Just as with normal (paper) documents, it is often vital to know that the content of a digital document has not changed after a certain point in time. A timestamp that confirms this gives a digital document legal validity equivalent to that of a normal document. The document is signed with a valid qualified digital certificate at a certain point in time by securely linking the time data of the signature with the data in the digital document.

Halcom CA has the status of a Trusted Third Party (TTP) and operates as a Time Stamping Authority (TSA). The role of a time stamping authority in electronic commerce is similar to that of an impartial witness in transactions with paper documents (e.g. a notary public).

The meaning of timestamps

The timestamp is legally valid proof that the electronic document existed at a certain point in time.
The timestamp confirms that the document has not changed since the moment of time stamping.
