Today a broad array of civil liberties groups, think tanks, and technology companies launched the Digital Due Process coalition. The coalition’s mission is to educate lawmakers and the public about the need to update U.S. privacy laws to better safeguard individual information online and ensure that federal privacy statutes accurately reflect the realities of the digital age.

Over 20 organizations belong to the Digital Due Process coalition, including such odd bedfellows as AT&T, Google, Microsoft, the Center for Democracy & Technology, the American Civil Liberties Union, the Electronic Frontier Foundation, The Progress & Freedom Foundation (where Berin works), the Competitive Enterprise Institute (where Ryan works), the Internet Technology & Innovation Foundation, Citizens Against Government Waste, and Americans for Tax Reform. The full member list is available at the coalition’s website.

Amidst the heated tech policy wars, it’s not every day that such a diverse group of organizations comes together to endorse a unified set of core principles for legislative reform. Over two years in the making, the Digital Due Process coalition, spearheaded by the Center for Democracy & Technology, is a testament to the broad consensus that’s emerged among business leaders, activists, and scholars regarding the inadequacies of the current legal regime intended to protect Americans’ privacy from government snooping and the need for Congress to revisit decades-old privacy statutes. It also represents a revival of a bipartisan consensus on the need for reform reached back in 2000, when the Republican-led House Judiciary Committee voted 20-1 to approve very similar reforms (HR 5018).

Today, in the digital age, robust privacy laws are more important than ever. That’s because U.S. courts have been unwilling to extend the Fourth Amendment’s protection against unreasonable search and seizure to individual information stored with third parties such as cloud computing providers. Thus, while government authorities must get a search warrant based on probable cause before they can lawfully rifle through documents stored in your desk, basement, or safe deposit box, information you store on the cloud enjoys no Constitutional protection. (Some legal scholars argue this interpretation of the Fourth Amendment, referred to as the Third Party Doctrine, is outdated and deficient. See, for example, Jim Harper’s excellent 2008 article in the American University Law Review.)

To be sure, this doesn’t mean that data stored in the cloud is completely without legal protection. In 1986, Congress enacted the Electronic Communications Privacy Act (ECPA), a then-forward-looking law that established several new privacy protections limiting governmental access to consumer data stored or transmitted by “remote computing service providers” and “electronic communications service providers.” Thanks to this law, along with earlier statutes such as the Wiretap Act, most electronic communications transmitted today enjoy some degree of legal protection. Unfortunately, the law’s provisions don’t reflect the reality of modern digital communications, nor do they offer sufficient protections for sensitive items like emails, mobile device locational information, and instant messages.

To remedy these deficiencies, the Digital Due Process coalition has offered four principles for Congress to consider as it revisits ECPA. In essence, they would require that government obtain:

• A search warrant from the court, upon the showing of “probable cause” required by the Fourth Amendment, before compelling “cloud” providers to disclose most kinds of private communications or mobile location information;
• A court order subject to meaningful judicial review before compelling providers to disclose dialed number information or email to and from information; and
• Judicial approval, rather than a mere subpoena, before compelling providers to disclose non-particularized information about individual accounts.

These proposed reforms, if enacted, would go a long way toward ensuring that individuals enjoy the same legal protections online that the Fourth Amendment has long provided in the offline world. The principles would also empower cloud computing and mobile service providers to offer more robust privacy assurances to users. Such assurances will help strengthen user trust in of cloud computing and, consequently, may spur innovation in cloud computing services that involve highly sensitive data like health information.

This call to action is also a reminder that restricting the power of government, not the private sector, is the solution to the privacy challenges of the digital age. Privacy advocates and zealots alike often focus on the risks of private data collection. Yet the greatest, and most demonstrable, of these risks comes not from private firms but from the real Big Brother: the risk that government will get its hands on private data without meaningful judicial oversight.

As we’ve long argued (see Ryan’s essay with Wayne Crews, “Selling Out Online Advertising,” and Berin’s comments to the FTC’s Exploring Privacy Roundtable last November), the consumer benefit of individualized data collection and use is nothing short of spectacular. Without it, services like Gmail, Google search, and Facebook likely wouldn’t exist. (And it’s only 2010—the best is yet to come!) Simply put, there is no free lunch!

But data collection has a real downside: As long as sensitive information remains stored on a provider’s server, there’s a risk that it will end up in the wrong hands. Through smart information security practices and privacy policies enforced both by the FTC and strong reputational forces, the private sector has generally done a good job of safeguarding individual data, with rare exceptions. Yet, today, no amount of security or legalese or good intentions can protect against a government subpoena issued in compliance with ECPA’s outdated, inconsistent and downright byzantine legal standards—which vary widely depending on whether messages have been opened, how long they’ve been on the server, etc.

The reforms proposed by the Digital Due Process Coalition would fix this gaping hole in America’s privacy laws, allowing individuals to rest assured that their personal information won’t end up in the hands of government unless probable cause is shown before a court of law. That’s the promise enshrined in the Fourth Amendment—a promise we seek to restore.

Facebook has been at the center of a controversy involving its moderation policies and The Pirate Bay, a popular Bittorrent tracker that was found guilty of copyright infringement by a Swedish court last month. Since early April, Facebook has enforced a “site-wide” ban on links to The Pirate Bay – including those in private messages.

This practice may run afoul of federal wiretapping statutes that bar service providers from “intercepting” private messages, according to an article that appeared on Wired Threat Level last week. Wired quotes Kevin Bankston, a senior attorney for the Electronic Frontier Foundation, who explains that Facebook’s filtering raises “serious questions about whether Facebook is in compliance with federal wiretapping law.”

It’s important to draw a distinction between the traditional notion of “wiretapping” and Facebook’s “interception” of user messages, which doesn’t involve any human intervention. Regardless of how the courts may interpret ancient laws like the 1986 Electronic Communications Privacy Act, an automated computer system flagging and deleting certain strings from user messages simply isn’t comparable to a third party secretly listening in on a private phone conversation.

Besides, Facebook makes clear to its users from the get-go that their messages and postings are subject to a set of rules (which Facebook lays out in plain English). If Facebook believes a message or posting is against the rules, it can block or remove it. This is not an unreasonable rule; many online discussion forums have enforced similar policies since the Web’s early days. Such filtering is possible only if sites can “examine” messages to identify misconduct.

Critics of Facebook’s filtering policies have rightly pointed out that even legal Pirate Bay links are being blocked. While this is a valid argument, it belongs on the feedback section of Facebook’s Site Governance page – not in a court of law. It isn’t the role of government to second-guess content judgments reached in good faith by social networking sites. Facebook must weigh a range of competing concerns in deciding how to cater to its hundreds of millions of diverse users. The same message that one user might consider “spammy” or malicious might be seen in a totally different light by another user. Add into the equation concerns over reputation and even potential copyright infringement liability, and it’s easy to see why Facebook has to make tough – and controversial – decisions all the time.

While I agree with Bankston that the legal ramifications of Facebook’s practices are far from clear, I’m concerned about the prospect of wiretapping laws being used against websites that moderate communications between users. If filtering Pirate Bay links from user messages constitutes illegal wiretapping, then it would seem that any social network or discussion forum that monitors and removes content from user-to-user communications would be in violation of federal law.

What would it mean for the Internet if websites were barred from moderating messages sent between users? AOL might not be able to “kids only” chat rooms; instant messaging services might be even more spam-ridden than they already are; and yoursphere, a social-networking site “just for kids,” likely wouldn’t even be able to exist.

Decisions about how to operate private online ecosystems are best left to individual firms competing in an open marketplace. Prohibiting website operators from moderating user messages may not bother people who don’t mind spam or porn (or Pirate Bay links), but what about people who desire a social network in which certain kinds of speech are off-limits?

One of the best aspects of the Web is that choices are abundant. If you don’t like one social networking site’s policies, you can go someplace else. Users can already send around links to Pirate Bay torrents through countless other social networking sites, email providers, and instant messaging services. Gmail, AIM, Ning, and Skype are just some examples of free online services that do not censor Pirate Bay links. Heck, if none of these options are satisfactory, you can even build your very own social network with free software like BoonEx and spread around all the Pirate Bay links you want.

Unlike with wiretaps, law enforcement agents are not required by federal statutes to obtain search warrants before employing pen registers or trap and trace devices. These devices record non-content information regarding telephone calls and Internet communications. (Of course, “non-content information” has quite a bit of content – who is talking to whom, how often, and for how long.)

The Electronic Privacy Information Center points out in a letter to Senate Judiciary Committee Chairman Patrick Leahy (D-VT) that the Department of Justice has consistently failed to report on the use of pen registers and trap and trace devices as required by law:

The Electronic Communications Privacy Act requires the Attorney General to “annually report to Congress on the number of pen register orders and orders for trap and trace devices applied for by law enforcement agencies of the Department of Justice.” However, between 1999 and 2003, the Department of Justice failed to comply with this requirement. Instead, 1999-2003 data was provided to Congress in a single “document dump,” which submitted five years of reports in November 2004. In addition, when the 1999-2003 reports were finally provided to Congress, the documents failed to include all of the information that the Pen Register Act requires to be shared with lawmakers. The documents do not detail the offenses for which the pen register and trap and trace orders were obtained, as required by 18 U.S.C. § 3126(2). Furthermore, the documents do not identify the district or branch office of the agencies that submitted the pen register requests, information required by 18 U.S.C. § 3126(8).

EPIC has found no evidence that the Department of Justice provided annual pen register reports to Congress for 2004, 2005, 2006, 2007, or 2008. “This failure would demonstrate ongoing, repeated breaches of the DOJ’s statutory obligations to inform the public and the Congress about the use of electronic surveillance authority,” they say.

It’s a good bet, when government powers are used without oversight, that they will be abused. Kudos to EPIC for pressing this issue. Senator Leahy’s Judiciary Committee should ensure that DoJ completes reporting on past years and that it reports regularly, in full, from here forward.

You can tell I like my writing when I take a sentence from a post and make it the title.

Annnyway, my brief comment on the whistleblower who outed “Stellar Wind” is on the Cato@Liberty blog.

The Progress & Freedom Foundation has just launched the new Center for Internet Freedom.  CIF offers an alternative to the proliferation of advocacy groups calling for government intervention online by offering timely analyses and critiques of proposals that diminish the vital role of free markets, free speech and property rights.  We aim to drive the Internet policy debate in new directions by emphasizing a layered approach of technological innovation, user education, user self-help, industry self-regulation, and the enforcement of existing laws consistent with the First Amendment.  Such an approach is a less restrictive—and generally more effective—alternative to increased regulation.  

Here are some of the issues I’ll be working on as CIF’s Director in conjunction with my esteemed colleagues Adam Thierer, Adam Marcus, and adjunct fellows: 

• Defending online advertising as the lifeblood of online content & services, especially in the “Long Tail”;
• Emphasizing market solutions to problems of privacy protection, especially regarding the use of cookies and packet inspection data;
• Protecting online speech and expression both in the U.S. and abroad;
• Defending Section 230 immunity for Internet intermediaries;
• Opposing online taxation and legal barriers to e-commerce and digital payments, especially at the state and local levels; and
• Ensuring that Internet governance remains transparent and accountable without hampering the evolution of the Internet.

Since the fall of 2008, a debate has raged in Washington over “targeted online advertising,” an ominous-sounding shorthand for the customization of Internet ads to match the interests of users.  Not only are these ads more relevant and therefore less annoying to Internet users than untargeted ads, they are more cost-effective to advertisers and more profitable to websites that sell ad space.  While such “smarter” online advertising scares some—prompting comparisons to a corporate “Big Brother” spying on Internet users—it is also expected to fuel the rapid growth of Internet advertising revenues from $21.7 billion in 2007 to $50.3 billion in 2011-an annual growth rate of more than 24%. Since this growing revenue stream ultimately funds the free content and services that Internet users increasingly take for granted, policymakers should think very carefully about what’s really best for consumers before rushing to regulate an industry that has thrived for over a decade under a layered approach that combines technological “self-help” by privacy-wary consumers, consumer education, industry self-regulation, existing state privacy tort laws, and Federal Trade Commission (FTC) enforcement of corporate privacy policies.

In an upcoming PFF Special Report, we will address the many technical, economic, and legal aspects of this complicated policy issue-especially the possibility that regulation may unintentionally thwart market responses to the growing phenomenon of users blocking online ads.

We will also issue a three-part challenge to those who call for regulation of online advertising practices:

1. Identify the harm or market failure that requires government intervention.
2. Prove that there is no less restrictive alternative to regulation.
3. Explain how the benefits of regulation outweigh its costs.

The Online Advertising Market

While there are other forms of targeted advertising based on who you are (“demographic”) or where you are (“locational”), the most important varieties are based on what you’re searching for, seeing or doing online at any particular moment (“contextual”) and the pattern of what you’re searching for, seeing or doing over time (“behavioral”). The bulk of Internet advertising falls into one or both of these last two categories, with behavioral advertising growing rapidly.

Search engines deliver contextual ads on search results pages based on the search keywords entered by a user, while third-party advertising networks (some of which also run search engines) deliver contextual ads on behalf of website operators who sell ad space to the network, with the ads displayed on each page chosen according to keywords on that page. Contextual advertising is far “smarter” than displaying the same “dumb” untargeted banner ads to every user, because the contextual ad uses keywords to “guess” what the user is interested in based on the context of each page. But the purely contextual ad network doesn’t “remember” what the user has looked at in the past, so its insights into what the user would find relevant are very limited, especially for some websites. Online behavioral advertising (OBA) solves this problem and increases the value of advertising space on all websites by targeting ads based on a “profile” of the user created by tracking websites the user has visited—as well as limiting the number of times a user is shown a particular ad.

The Perceived Harm Driving Calls for Regulation

For a decade, the basic technology behind OBA has changed little: When a user visits the typical webpage, they download not only the webpage contents but also a small piece of code that allows the website to distinguish that user’s browser from other browsers (a “cookie”)—without personally identifying the user. Some cookies are required to make sites work properly (“site cookies”) while others (“tracking cookies”) are used by the third party ad network in which that site participates to recognize that browser across multiple sites participating in the ad network, and thus create a “profile” of what the user might be interested in. Even though such profiles themselves are anonymous, many privacy advocates have pointed to four reasons why online profiling is becoming “too invasive:” (i) It is sometimes possible to infer the actual identity of the user; (ii) though all browsers allow users to opt-out of tracking by “cleaning out” their tracking cookies, a website may be able to restore deleted tracking cookies through the use of cookie alternatives such as “Flash cookies”; (iii) certain vulnerabilities in current browser design make it theoretically possible to “sniff” a user’s browsing history, cache or bookmarks; and (iv) the use of “packet inspection” by Internet Service Providers (ISPs) (instead of the use of cookies) to track online browsing amounts to illegal wiretapping.

The other concerns expressed by the advocates of regulation vary significantly. Some fear that browsing profiles could be captured by hackers, somehow associated with personally identifying information, and used for identity theft. These advocates demand limits on data retention as well as data security mandates. Others demand that users have access to their own profiles—a goal inherently in tension with data security. Most share a vague queasiness about “being tracked” and about advertising in general, while downplaying the effectiveness of self-regulation or user self-help.

Perhaps most legitimately, others fear that the real “Big Brother”—the government—will gain access to a “honeypot” of surveillance data that might be associated with individual users. A variety of other solutions have been proposed to what is, for the most part, a poorly defined problem, including a government-run “Do Not Track” registry to make it easier for users to block tracking cookies; mandating opt-in for some or all forms of profiling; and banning completely the collection of tracking data about sensitive subjects, cross-referencing of data sets, and use of packet inspection data for OBA.

The Less Restrictive Means: A Layered Approach

But how should policymakers decide which, if any, of these interventions are really necessary–or would even be effective? Ironically, those who demand immediate OBA regulation to protect user privacy are often the first to insist on less burdensome approaches whenever a policy “problem” involves purely non-commercial speech. For example, emphasizing personal and parental responsibility is often favored as the more sensible approach to dealing with free speech and child protection concerns. But, as Chapman University Law Professor Tom Bell has asked, why not apply the same standard across the board? Why not expect those especially privacy-sensitive users who object to OBA to do something about it? To the extent effective self-help privacy tools exist, they provide a means of solving policy problems that is not only “less restrictive” than government regulation but generally more effective and customizable as well. Why settle for one-size-fits-all solutions of incomplete effectiveness when users can quite easily and effectively manage their own privacy? Indeed, those who advocate personal responsibility and industry self-regulatory approaches to free speech and child protection issues should be advancing the same position with regards to privacy.

Fortunately, a wide variety of self-help tools and “technologies of evasion” are readily available to all users and can easily thwart traditional cookie-based tracking, as well as more sophisticated tracking technologies such as packet inspection. While cookie management tools that allow users to delete their cookies have been standard in browsers for some time, the latest generation of browsers incorporates far more advanced control over what kind of cookies browsers will accept from websites in the first place. Furthermore,  the extensible nature of modern browsers allows any freelance software developer who sees a way to improve a browser to do so by writing an add-on that “plugs in” to the browser using standard programming interfaces designed by each browser developer.  Many such add-ons are wildly popular, but even those users who never install a single one benefit from the acceleration of browser evolution made possible by add-ons.  We will be documenting examples of these tools in our upcoming Special Report and in an ongoing  series of blog essays.

The Benefits of Smarter Advertising

The “free” Internet economy is based on a simple value exchange: Users get access to an ever-expanding collection of content and services at no cost from websites that are able to generate revenue from “eyeballs” on their pages by selling space on their sites to advertisers, usually through ad networks. The smarter that advertising, the more free content and services it can support. This is the same value exchange that has supported free, over-the-air television and radio content for decades. The only difference is technological: Because websites can connect directly with the user, they need not rely on crude profiling tools such as Nielsen ratings.

There are larger economic benefits of smarter online advertising. First, it makes the overall economy more open and competitive by allowing small market entrants to reach consumers with messages about their products. Second, those who attack the use of packet inspection by ISPs for OBA fail to see that it is precisely the kind of “game-changer” that could disrupt Google’s currently dominant market position. Third, the involvement of ISPs in OBA could help defer broadband costs: Even if OBA revenue does not completely subsidize monthly service costs, smarter advertising could at least keep prices in check and potentially lower them significantly going forward.

But smarter advertising isn’t just about selling products or services. It is ultimately about making all kinds of speech more cost-effective. The ability to “target” listeners more narrowly also increases the ability of political and other not-for-profit speakers to communicate their messages. In short, smarter advertising means more voices, more choices, and more speech. The line between “advertising” and “content” is already blurring rapidly, as the technologies used to customize advertising are also used to customize webpages and ad networks themselves are used to deliver content.

The Larger Implications of Potential Regulation

As if reducing the advertising revenue generated by each web ad didn’t do enough to reduce the total amount of funding for free web content and services, government regulation of targeted online advertising could reduce advertising revenues even further by aggravating the problem of adblocking in two ways. First, the less relevant ads are, the more annoying users will find them, and the more likely users are to try to block them. Increased relevance is perhaps the most important remedy for adblocking and the best way to maintain the implicit value exchange that currently supports free Internet content and services

Second, regulation could short-circuit the eternal battle of technological one-upmanship between online advertisers and those users who rely on the technologies of evasion to “opt-out” of seeing ads or being tracked. Such privacy-conscious users are “free-riding” off of those users who don’t opt-out, since (at present) they generally don’t lose access to the free content and services supported by the targeted advertisements that other users do see. The user who blocks tracking, but not ads, is still free-riding off those users who don’t opt-out of tracking. On a large enough scale, such self-help has the potential to disrupt the value exchange of the Internet, just as automatic commercial-skipping has already disrupted the value exchange of television. As with all “Spy v. Spy” battles, this long-term trend is inevitable: As more sophisticated technologies of evasion are incorporated seamlessly into browsers and can be used without significantly degrading the browsing experience, their use will become increasingly mainstream. But ultimately, just as with television commercial-skipping, market forces can and will, if permitted, respond through technological means and the development of new business models. Today’s implicit quid pro quo may become, of necessity, explicit: Websites and ad networks will have to find increasingly creative ways to grant access to certain content and services for users who do not block ads or the tracking that makes ad space more valuable. Policymakers should take care not to ban such technologies or cripple such business models (e.g., through requiring opt-in), which may rely on more sophisticated forms of targeting such as the use of packet inspection data.

As users face an increasingly clear choice between (i) getting content and services for free supported by behavioral advertising and (ii) paying to receive those same services and content without tracking or even without ads altogether, policymakers will finally see whether users are really as bothered by profiling as the advocates of OBA regulation insist. Given the ongoing and widespread replacement of fee- or subscription-supported web business models with ad-supported models, it seems likely that the vast majority of consumers will continue to choose ad-supported models, including profiling.

Conclusion

The questions raised above—about the harm that supposedly requires intervention, the availability of less restrictive means, and the cost/benefit analysis of regulation—are vital considerations for the future of the Internet. Indeed, if smarter online advertising will not fund the Internet’s future, what will? As both the desire for “free” services and content and the need for bandwidth expand, OBA has the potential to offer important new revenue sources that can help support the entire ecosystem of online content creation and service innovation, while also providing a new source of funding for Internet infrastructure and making ads less annoying and more informative. That would certainly seem preferable to increased user fees or other “pay-per-view” pricing models for Internet content and services.

But looming legislative and regulatory action could stop all of that by replacing the current regime—in which the FTC merely enforces industry self-regulatory policies—with one in which the government preemptively dictates how data may be collected and used. The more enlightened approach is a “layered” approach to privacy protection that combines industry self-regulation, enforcement of industry-established privacy policies, consumer education, and user “self-help” solutions. These and other issues will be addressed in greater detail in our upcoming PFF Special Report.
