Abstract
A set of security templates is maintained including first and second templates. The first template specifies time and location stamp authentication for a file, and contextual security conditions that must be met before the file can be accessed. The second template specifies the time and location stamp authentication, but not the contextual security conditions. One of the first or second security templates is applied to the particular file. When the second security template is applied, a GPS-crypto device adds a time and location stamp to the particular file. The particular file is signed using a private key associated with the GPS-crypto device to generate an authentication signature based on the time and location stamp. The authentication signature is added to the particular file to allow a recipient to verify the time and location stamp of the particular file using a public key corresponding to the private key.
