Abstract
A method for recovering data. Identity factors are collected at a device, wherein hashes of the identity factors are configured to be stored at a server. A dynamic password is generated at the device based on the identity factors and a Salt generated by the server and configured to be delivered to the device. A selfie is captured of a user. The device generates a symmetric key used to encrypt the selfie. The symmetric key is encrypted using the dynamic password. The encrypted symmetric key and the encrypted selfie are stored on the server. One or more data items are stored on the server. The dynamic password is recoverable by presenting the plurality of identity factors that are hashed to the server. The symmetric key is recoverable using the recovered dynamic password. The data items are recoverable by presenting the symmetric key and a second selfie of the user.
