The organization has implemented electronic mechanisms to corroborate that electronic protected health information (ePHI) remains unaltered and has not been destroyed in an unauthorized manner. This proactive approach aligns with the Health Insurance Portability and Accountability Act (HIPAA) requirements, ensuring the integrity and security of sensitive health information.

Hashing Algorithms:

Implementation of robust hashing algorithms to generate unique cryptographic hash values for ePHI. These hash values act as digital fingerprints, allowing verification that the data has not been altered.

Digital Signatures:

Utilization of digital signatures for certain types of ePHI, providing an additional layer of authentication and ensuring the origin and integrity of the information.


Inclusion of timestamps in electronic records, facilitating the tracking of when specific changes or accesses occurred. This enhances the ability to detect and respond to unauthorized alterations promptly.

Regular Integrity Checks:

Establishment of regular integrity checks on stored ePHI, comparing current cryptographic hash values with baseline values to identify any discrepancies that may indicate unauthorized alterations.

Audit Logging and Monitoring:

Implementation of audit logging and monitoring systems to track access and modifications to ePHI, ensuring a comprehensive record of electronic activities for corroborative purposes.
