Abstract
A method is disclosed. The method includes receiving, by a processing network computer from a relying party computer associated with a relying party, a request for data associated with a user operating a user device. The processing network computer may retrieve first encrypted data of the user having a user-layer of encryption. The processing computer can then generate a second symmetric key to add a relying party-layer of encryption to the first encrypted data using a stream cipher. The doubly encrypted data may be transmitted to a user device that removes the user-layer of encryption on the first doubly encrypted data, and then adds a second relying party-layer of encryption to form second doubly encrypted data. The second doubly encrypted data may be transmitted to the relying party computer, which can remove both relying party-layers of encryption to gain access to the data associated with the user.
