Profile: Phil Zimmerman
Phil Zimmerman was a participant or observer in the following events:
Phil Zimmerman, the creator of the highly regarded “Pretty Good Privacy” (PGP) protocols, sounds an alarm about the 1994 Communications Assistance for Law Enforcement Act (CALEA), which mandated that telephone providers aid government wiretapping “by installing remote wiretap ports onto their digital switches so that the switch traffic would be available for snooping by law enforcement. After CALEA passed (see January 1, 1995), the FBI no longer had to go on-site with wiretapping equipment in order to tap a line—they could monitor and digitally process voice communications from the comfort of the home office.…CALEA opened up a huge can of worms….” Zimmerman writes, “A year after the CALEA passed, the FBI disclosed plans to require the phone companies to build into their infrastructure the capacity to simultaneously wiretap 1 percent of all phone calls in all major US cities. This would represent more than a thousandfold increase over previous levels in the number of phones that could be wiretapped. In previous years, there were only about a thousand court-ordered wiretaps in the United States per year, at the federal, state, and local levels combined. It’s hard to see how the government could even employ enough judges to sign enough wiretap orders to wiretap 1 percent of all our phone calls, much less hire enough federal agents to sit and listen to all that traffic in real time. The only plausible way of processing that amount of traffic is a massive Orwellian application of automated voice recognition technology to sift through it all, searching for interesting keywords or searching for a particular speaker’s voice. If the government doesn’t find the target in the first 1 percent sample, the wiretaps can be shifted over to a different 1 percent until the target is found, or until everyone’s phone line has been checked for subversive traffic. The FBI said they need this capacity to plan for the future. This plan sparked such outrage that it was defeated in Congress. But the mere fact that the FBI even asked for these broad powers is revealing of their agenda.” [Ars Technica, 12/20/2005]
