Identity Theft Protection Using Encrypted Fragmented Data Storage

The patent segments personal identity information into multiple encrypted fragments stored at geographically separate secure locations rather than at a single central database. This segmentation ensures that no single point of failure exists, and even if one location is compromised, the complete identity information cannot be reconstructed without all fragments, thereby reducing vulnerability to identity theft while maintaining transaction convenience through distributed access.

The patent introduces controlled use cards as intermediaries between users and merchants. These cards contain encrypted account information that allows transaction processing without exposing actual personal identity information to merchants or storing it at merchant data locations. The controlled use card acts as a mediator that enables convenient transactions while protecting against identity theft by never revealing the user's true identity information.

The patent creates controlled use cards that are copies or representations of actual account information. These cards contain encrypted data that can be processed for transaction accuracy verification without revealing the actual personal identity information. The copy enables precise transaction processing while the encryption and controlled access prevent identity theft, as the merchant receives a functional copy rather than the original sensitive information.

The patent changes the state of personal identity information from plaintext to encrypted form through cryptographic transformation. This parameter change allows the information to be processed for transaction accuracy (through encrypted verification) while preventing unauthorized access and identity theft. The encrypted form maintains the functional properties needed for transaction processing while eliminating the security risk of exposing actual identity data.
