Abstract
Systems and methods are provided for restoring backup data files. One example computer-implemented method includes receiving a restore request including a backup data file having an L1 file, a wrapped L1 key, and an L4 file having an attribute of a user. In response, the method includes unwrapping the L1 key with a private key, decrypting the L1 file via the L1 key, and verifying a sample biometric included in the restore request against a reference biometric from the L1 file. Upon verification of the sample biometric, the method includes decrypting an L2 file of the L1 file, verifying a contact attribute from the L2 file with the user, decrypting an L3 file using the contact attribute, wrapping an L4 key from the L3 file with the public key of the restore request, and transmitting the wrapped L4 key to a mobile device of the user.
