Doug Tygar

Current Research

Professor Tygar examines issues in computer security, privacy, electronic commerce, and related policy areas. His recent research has included recovering keystrokes from a recording of a user typing at a computer keyboard, creating techniques for securing sensor nodes (described in part in his book Secure Broadcast Communication with Adrian Perrig), developing powerful anti-phishing techniques, exploring the usability of computer security systems, and examining systems for protecting privacy in government database systems. Professor Tygar has previously helped developed a number of important electronic commerce systems, including the US Postal Service's Information Based Indicia (cryptographically protectred 2-D bar codes used for postage) and the NetBill system.
