COMPLEX FORMAT-PRESERVING TOKENIZATION SCHEME

摘要

Methods, computing systems and computer program products implement embodiments of the present invention that include defining multiple primitives, each of the primitives including ranking and unranking methods. Two or more of the multiple primitives are selected, and an operation is performed on the selected primitives, thereby defining a complex format. Upon an encryption processor receiving a data record including a plaintext, the complex format is applied to the plaintext, thereby generating a non-reversible token. In some embodiments, the generated token is transmitted a remote computer.

1. A method, comprising:
defining multiple primitives, each of the primitives comprising ranking and unranking methods; selecting two or more of the multiple primitives; performing an operation on the selected primitives, thereby defining a complex format; receiving a data record comprising a plaintext; and applying, by a hashing processor, the complex format to the plaintext, thereby generating a non-reversible token.
