Abstract:
1. A method, comprising: receiving at a personal identification device a first section of a symmetric key in encrypted form, a second section of the symmetric key in encrypted form and biometric data in encrypted form from a backup storage repository separate from the personal identification device, the first section of the symmetric key being different than the second section of the symmetric key; verifying a validity of a signature associated with the first section of the symmetric key based on a public key associated with the personal identification device; and combining the first section of the symmetric key and the second section of the symmetric key to restore the symmetric key after the validity of the signature is verified such that the symmetric key is configured to decrypt the biometric data in encrypted form to restore the biometric data; wherein the personal identification device is a first personal identification device, and wherein the biometric data was previously stored on a second personal identification device.
