Internet-based text message apps are one of the most common means of communicating today. But when it comes to this relatively new technology, surveillance law is behind the times in important ways, and as is so often the case when the law lags technology, our privacy suffers as a result.

Text messages have for some time been a cash cow for the wireless carriers—back in 2007, annual global SMS revenue was estimated to be 60 billion dollars. Charging consumers 25 cents per 140 character text message is a great way to make money, but when those same consumers are already paying for internet connectivity to their smartphones, the market was ripe for disruption. In recent years, a number of internet companies have entered the text message market. In some cases, they have offered low-cost or free SMS services that interoperate with the carriers’ existing SMS system. In other cases, large companies like Facebook, Apple and WhatsApp have offered closed text message services to their smartphone using customers. Often seeking to reduce their monthly telephone bills, millions of consumers have migrated from smartphone text message services provided by the wireless carriers to smartphone text message services provided by internet companies.

Want to keep your information private now that Google has started rolling out “Search, plus Your World,” a new search results format? For those signed-in with a Google account, the new feature combines search results from the public web plus private information and photos you have shared (or have been shared with you) through Google+ or Picasa.

Can using privacy-enhancing tools (such as Tor or a Virtual Private Network) actually expose you to warrantless surveillance by the National Security Agency? This week, the ACLU sent off four FOIA requests to federal agencies in order to try and answer this question.

To understand why we think that may be the case, we have to go back to the passage of the FISA Amendments Act (FAA) in 2008. That act was not a high-point for civil liberties or the rule of law. It included a provision giving immunity to the telecom companies that violated the law by assisting the NSA with its warrantless wiretapping program. Although the get-out-of-jail-free card given to the phone companies is the most well-known aspect to the FAA, there is much more to the law, and many other things that give privacy advocates reason to worry.

In a disturbing trend that can have a chilling effect on free speech, law enforcement agencies around the country are seeking wide-ranging information about the social networking activity of political activists. The San Francisco District Attorney recently issued subpoenas to Twitter for tweets by two political protesters, Lauren Smith and Robert Donohoe, who had been charged with rioting and unlawful assembly during a Columbus Day demonstration last year. They had been active on Twitter but disabled their accounts after the protest.
