![]() ![]() SHA-2 Fingerprinting has these properties:.Instead, its SHA-2 fingerprint (more info), is transmitted and stored in our database to enable easy on-line verification of the file's time stamp. Your file is never transmitted to us or stored.Total confidentiality and secrecy of your document, which is also secret from us.SHA-2 validity chain is intermittently published in other media, which preserve the time-stamp integrity, even if the above methods were to lose credibility due to events such as server security compromise.Electronically Signed Certificate is issued which allows off-line verification of authenticity, even if our database were to become unavailable.Time Stamps are recorded in our database.Several different methods maintain the integrity of the time-stamping record, even if some of these methods were to cease to function or if they were to lose credibility due to unforeseen compromise of our server's security, or unforeseen compromise of one of the cryptographic methods.Well-known and widely-accepted Mathematical, Cryptographic and Database Methods are used to provably record the existence of your file, in a way that keeps the file contents secret, and is considered impossible to forge.Timestamping authority that provides extremely robust proof that your invention, copyrightable work, design, idea, or document existed today.
