AbsoluteProof by Surety is a cryptographic timestamping service that allows users to apply tamper-evident digital 'Seals' to electronic information, ensuring long-term proof of its existence and integrity. It can be deployed on the desktop, in the enterprise, or in the cloud, providing a solution for intellectual property protection, digital evidence protection, and proving the authenticity of electronic records and files. AbsoluteProof safeguards critical documents against tampering, proves record authenticity, protects digital intellectual property, preserves digital evidence, demonstrates regulatory compliance, and ensures litigation readiness. It supports independent verification of electronic record authenticity using secure hash algorithms like SHA-256 and RIPEMD-160. AbsoluteProof integrates seamlessly into various platforms with lightweight, pre-configured modules and software development kits, making it compatible with any data source, including documents, records, email, electronic health records, engineering diagrams, scientific device readings, audio, video, CAD diagrams, and audit logs. The service is based on standard hash functions and widely-witnessed integrity values, ensuring long-lasting protection of electronically stored information (ESI). AbsoluteProof's patented Seal renewal process allows for upgrading protection without relying on cryptographic keys or certificates that can expire or be compromised.
