1) CDT Testifies at House Judiciary Committee Data Retention Hearing
In late January 2011, the House Judiciary Subcommittee on Crime, Terrorism, and Homeland Security held a hearing on "Data Retention as a Tool for Investigating Internet Child Pornography and Other Internet Crimes." The informational hearing focused whether ISPs and online service providers should be made to collect and retain information about their users' Internet communications, so that law enforcement could access the inform in child pornography and other criminal investigations.
At issue is the fact that most ISPs provide subscribers with “dynamic” IP addresses, meaning that the IP address assigned to a particular user will change every few days or weeks. When law enforcement is pursuing a case of online child exploitation, they may have the IP address of a user who sent or received the child pornography file. To assist law enforcement, the leading ISPs in the United States have voluntarily kept records of their IP address allocations so that, for limited periods of time, the ISPs would be able to tell law enforcement who had a given IP address on a particular date and time. But some law enforcement officials and legislators want to make this kind of data retention mandatory.
