Abstract:
Devices and methods are disclosed which relate to managing multiple public user identifiers (PUIDs) in a database by setting customizable access rules and requiring authorization from applications for access. These PUIDs can be virtually any electronic identifier such as a telephone number, email address, FACEBOOK name, etc. The PUID database is on the memory of a mobile communication device. Applications on the mobile communication device or on the network request access to the PUID database. Access logic on the mobile communication device checks another database of PUID Access Policies and Preferences (PAPP) for authorization. The PAPP database may allow the application immediate access, deny access, or query the user for allowance. The PUID database and PAPP database are on a server on a network.
