Abstract: A computer-implemented method includes receiving an authentication request from an external device for authenticating an application on the external device, and receiving a plurality of information items in connection with the authentication request from a plurality of different externally residing information sources. The authentication request is then evaluated, which includes evaluating each of the plurality of information items, to determine an authentication status of the application. Based on the authentication status, the device is then selectively permitted access to private information through the application. A computer system and/or machine-readable media may be provided to perform some or all steps of the method.
