This whitepaper presents the data authentication and integrity assurance framework developed by Assureon. It outlines the challenges of ensuring archived files remain readable, accessible, and undamaged, while also addressing concerns over accidental or malicious deletions. The document details Assureon's patent-pending technology that safeguards information assets through a tamper-resistant system. Key features include immutability, where files are assigned a unique digital fingerprint, and serialization, which provides a globally-unique sequential serial number for each asset. The system performs regular integrity checks and can automatically replace corrupted files using redundant copies. Additionally, it describes the assured individual key destruction process, which ensures complete deletion of files at the end of their retention period. The whitepaper emphasizes the importance of audit reports and electronic inventory checks to maintain confidence in the security and integrity of archived assets.
