For a timestamp to be valid, compliant with standards and provide independent evidence, it has to be issued by a Trusted Third Party (TTP) called a Time Stamping Authority (TSA), which PROOFIP is.

The timestamping Service uses Public Key Infrastructure (PKI) and trusted time sources based on international standards IETF RFC 3161, Time-Stamp Protocol (TSP), IETF RFC 5816.

A timestamp confirms the existence of electronic data at a specific time. It cannot be backdated and certifies that the data has not been subsequently altered.

The technology provides a secure and immutable record of the digital time stamping processes and their results using an innovative, independent, and unique digital fingerprint – the hash value.

Due to the cryptographic technology used by the Time Stamping Authority, all data become and remain completely confidential and immutable.

A strong cryptographic hashing function processes the digital document while it is still on the owner's computer, producing a hash value which uniquely identifies the file. It is not possible to read or recreate the original file from the hash value, ensuring 100% confidentiality.

PROOFIP never gets access to the content and does not store the original file.

  The Service is developed in accordance with international requirements and standards: IETF RFC 3161 Time-Stamp Protocol (TSP). IETF RFC 3628 Policy Requirements for Time-Stamping Authorities (TSAs).
