Presentation transcript:

Intercepting Communications Wiretapping Telephone: Pre-1934: used widely by government, businesses, and private sector. 1934: the Federal Communications Act disallowed unauthorized wiretaps; many ignored the law. 1968: the Omnibus Crime Control and Safe Streets Act restricted wiretapping by requiring a court order. Q: Can law enforcement intercept communications without a court order?

Intercepting Communications Wiretapping New Technologies: 1986: Electronic Communications Privacy Act (ECPA) and its amendments restricted government interception of e-mail, cell-phones, etc.. 2001: USA Patriot Act loosened restrictions on government wiretapping and communications interception. Q: Does the USA Patriot Act supersede ECPAs restrictions?

Intercepting Communications Designing Communications Systems for Interception and Tracking Obstacles to interception: Incomplete pen-registers as a result of long distance service. Packet-mode communications (e-mail, file transfers, Internet phones). Solutions: CALEA: Requires telecommunications equipment be designed to ensure interception by law enforcement (with court order). Q: Why did privacy advocates object to CALEA?

Intercepting Communications Designing Communications Systems for Interception and Tracking (cont’d) CALEA Costs include modified hardware, software, and overuse by authorities. Wiretappable systems vulnerable to criminal hacking, industrial spies, etc.. Competition weakened due to restricted changes and diversities. Civil liberties threatened by nationwide standard for surveillance. Q: CALEA allows for the interception of PINs. Do you support this use?

Intercepting Communications Carnivore FBI’s system to intercept e-mail with a court order. Pro: Law enforcement needs this tool to fight crime. Con: All e-mail goes through FBI’s Carnivore system. Q: Does Carnivore violate the 4th Amendment?

Intercepting Communications NSA and Echelon NSA (National Security Agency): Collects and analyzes communications to find threats to national security. Echelon: Member nations intercept communications for each other. Q: Should the NSA be permitted to intercept all e-mail entering and leaving the U.S.?
