IDENTIFICATION SERVICE BASED AUTHORIZATION

Using various embodiments, methods and systems for securing user data are described. In one embodiment, a system receives a user authentication token, an application identification, and a cryptographically random number from a software application. It then generates an identification hash value using the received information and determines whether the generated identification hash value corresponds to another identification hash value known to the system. If the hash values correspond, it authorizes the software application to perform actions on behalf of a user.
