US Patent 11803622 System for improving data security when redeeming data

When personally identifiable information (PII) is to be stored or updated, a system first seeks consent from the user for the PII store or update. If the user grants consent, then the system stores the PII in the user's personal device or updates the PII stored in the user's personal device. The system then retrieves that PII and generates a token representing that PII. Even if the token were taken by a malicious user, it would not be possible for the malicious user to determine the user's actual PII from the token. In this manner, the security of the PII is improved over conventional systems.
