According to a new study by the Ponemon Institute, public trust in the United States government's commitment to protect privacy has fallen to a new all-time low. The survey of 75 federal organization examined the protection of personal information by federal agencies as well as the commitment to keep secure personal information. For 2010, the average privacy trust score across the United States government fell to 38%, from 50% in 2009. The top-rated government entities included the Postal Service, the Federal Trade Commissions, and the IRS, while the least-trusted agencies were the National Security Agency, the Department of Homeland Security, and the Department of Justice. The largest decline in trust over privacy matters came for the Census Bureau, which is preparing the 2010 census. The largest favorable change was at the Department of State.
