A recently granted patent (Publication Number: US11757626B1) describes a system and method for deterministic cryptography deidentification enabling granular destruction. The invention involves the use of a non-transitory computer-readable medium with instructions that, when executed by a processor, perform various operations.

The first claim of the patent describes the preparation of a table of name-token pair groupings with unique tokens. These pairings are randomly assigned based on the output of a cryptography random generator. The name-token pair groupings are used in a deidentification process, where each unique token is assigned to a group of separate data. The data is stored in a centralized repository, deidentified using an encryption key and a secured tag. The system also enables the identification of a token from the table, allowing for the reidentification of specific data items based on the provided token.

The second claim adds the operation of disposing of the token from the table of name-token pair groupings after use. This ensures that the token is no longer accessible or usable once the data has been reidentified.

The third claim specifies that the deterministic cryptography used in the deidentification process is performed via authenticated encryption with associated data cryptography. This ensures the security and integrity of the deidentified data.

The fourth claim highlights that the data being deidentified includes personal identifiable information. This indicates that the invention is particularly useful for protecting sensitive personal data.

The remaining claims describe additional features of the invention, such as the structure of the table of name-token pair groupings, the size of the token compared to the encryption key, and the inclusion of operations to deidentify data using the table.

Overall, this granted patent presents a system and method for deterministic cryptography deidentification enabling granular destruction. It offers a secure and efficient way to deidentify data while allowing for reidentification when necessary. The invention is particularly relevant for protecting personal identifiable information.
