Secure Data Exchange Using Format-Preserving Encryption - A simplified explanation of the abstract

This abstract first appeared for US patent application 17661773 titled 'Secure Data Exchange Using Format-Preserving Encryption

Simplified Explanation

The patent application describes methods and systems for tokenizing data to create a secure token.

• Tokenizing data means converting it into a secure token that is limited in scope and time.
• The secure token is directed to a specific recipient and is valid only for a specified period.
• The invention includes a detokenization process to recover encrypted data from the secure token.
• The detokenization process does not require any relational database lookup, reducing cost.
• The system ensures robust protection against unintended recipients trying to access the encrypted data.

Original Abstract Submitted

Methods and systems disclosed herein describe tokenizing data to generate a secure token that is limited in scope (e.g., directed to a specific recipient) and limited in time (e.g., valid for only a specified period of time). A detokenization process may be employed to recover encrypted data of the secure token without the need for any relational database lookup processes, thereby reducing cost while maintaining robust protection against unintended recipients that attempt to recover the encrypted data.
