Patent ID: 7596812

Claim:
A method for transferring protected data having an authorizing entity's outer encryption layer and having a user-fixed inner encryption layer from a first electronic device having a first unique, unalterable identifier to a second electronic device having a second unique, unalterable identifier, the method comprising: receiving protected data having a first unique, unalterable identifier of the first electronic device, a first outer encryption layer, and the user-fixed inner encryption layer from the first electronic device, wherein data having the user-fixed inner encryption layer is generated by encrypting data using a first user-fixed encryption key, the first user-fixed encryption key being generated from a first user input received at the first electronic device, wherein the first outer encryption layer is generated by encrypting the data having the user-fixed encryption layer using a first authorizing entity-shared encryption key corresponding to the first unique, unalterable identifier of the first electronic device; verifying the first unique, unalterable identifier of the first electronic device; generating, in response to the verification, the data having the user-fixed inner encryption layer by decrypting the first outer encryption layer using a first authorizing entity-shared encryption key corresponding to the first unique, unalterable identifier of the first electronic device; encrypting the data having the user-fixed inner encryption layer with a second outer encryption layer using a second authorizing entity-shared encryption key corresponding to the second unique, unalterable identifier of the second electronic device; appending, in response to the encryption, a second unique, unalterable identifier of the second electronic device; and transmitting the protected data having the second unique, unalterable identifier of the second electronic device, the second outer encryption layer, and the user-fixed inner encryption layer to the second electronic device, wherein the second electronic device decrypts the protected data using the second authorizing entity-shared encryption key corresponding to the second unique, unalterable identifier to form the data having the user-fixed inner encryption layer, and decrypts the data having the user-fixed inner encryption layer using the first user-fixed encryption key generated from a second user input received at the second electronic device.
