Matt Bishop, associate professor of computer science at ºÙºÙÊÓƵ, can discuss security issues concerning electronic voting systems. In January 2004, Bishop was on a team of experts from universities and industry asked by the state of Maryland to test security in the Diebold AccuVote-TS voting system. The team found security flaws that would allow tampering with machines, access to databases and interference with recording and tallying votes. They made recommendations for short-term measures to reduce those risks, such as placing tamper-proof seals on the machines. A copy of the team's report, prepared by RABA Technologies LLC of Columbia, Md., is available online. Bishop is co-director of the Computer Security Laboratory at ºÙºÙÊÓƵ, recognized by the National Security Agency as a center of excellence. He is the author of "Computer Security: Art and Science" (2002).
