Secure generation and inversion of tokens

DWPI Title: Apparatus for generating the tokens for the character strings, particularly the account numbers, comprises a memory that is loaded with instructions executed by the processor for generating the token representing string
Abstract: Described herein are various technologies related to secure generation of tokens and secure inversion of tokens. A tokenization system executes in a secure execution environment, and is configured to receive a string and an encrypted tokenization function. The tokenization system decrypts the encrypted tokenization function, and executes the tokenization function over the string to generate a token. The token is transmitted to a logically separate computing environment, and the tokenization system deletes the tokenization function and the string.
Use: Apparatus for generating the tokens for the character strings, particularly the account numbers, and social security numbers.
Advantage: The request is received to generate the token that is representative of the string from a logically separate computing environment, and hence ensures secure generation of the tokens.
Novelty: The generating apparatus comprises a memory (112) that is operably coupled to the processor (102), where the memory is loaded with instructions executed by the processor for generating the token representing string that conforms to a predefined format. A request is received to generate the token that is representative of the string from a logically separate computing environments (106,108). A tokenization function and string responsive are deleted to the generated token. The string is outputted to the logically separate computing environment.
