Long-term legal archiving

Perennity is an innovative and powerful way to provide long-term legal proofs of existence, based on the cryptographic archiving. It cannot replace traditional archiving, but adds a long-term proof of existence module to an existing process.

Perennity allows you to maintain proofs of existence of signed and unsigned documents: each element is regularly "re-protected" to take into account cryptographic breakthroughs or end of life of any component. It is of utmost importance for signed documents, allowing them to extend their validation time.

Even after 20, 30 or 40 years, you can easily provide verifiable evidences of existence which can convincingly hold in court thanks to integrity proofs.
