US Patent 9223950 Security challenge assisted password proxy

Systems, apparatus, and methods of authentication utilizing contextual data to authenticate individuals and prevent security breaches are described herein. An example proxy engine may monitor interactions with a computing device to obtain contextual data unique to a user. The contextual data may be utilized to generate unique challenge questions in response to requests for access to a secure resource, and may eliminate the need for a user to remember credentials to access the resource. Challenge questions may be limited to a single use and vary in difficulty in proportion to the value of the resource. In response to correct responses to challenge question(s), the proxy engine may access a vault containing a credential authorizing access to the resource. The vault and proxy engine may be entirely contained on the computing device or they may be implemented on a remote apparatus accessed via an application or interface on the computing device.
