Trusted timestamping is used to prove the existence of certain data before a certain point (e.g. contracts, inventions description,...) without the possibility that the owner can backdate the timestamps.
The technique is based on digital signatures and hash functions.
According to the RFC 3161 standard, a trusted timestamp is a timestamp issued by a trusted third party (TTP) acting as a Time Stamping Authority (TSA). ANSI ASC X9.95 standard also requires the third party to prove that a reliable time source was used.
