A document’s ownership and authenticity can be validated using a digital signature. A timestamp additionally serves to enable verification of the precise time an electronic document was signed.

With the increasing popularity of digital signatures in completely electronic workflows, such verification is becoming critical. Timestamps allow the time factor to be integrated into electronic workflows, as they are a mechanism for subsequently verifying when a document was created.

Particularly in electronic document archiving, it is imperative that the time when a document was signed can be conclusively verified at a later time (e.g., for auditing purposes). Timestamps therefore form the basis for long-term archiving of electronically signed content.

As a rule, any electronic document can be time stamped, which makes timestamps ideal for protecting audit and log data, too.

The TC TrustCenter Time Stamping Service lets you affix time stamps to your electronic documents and is billed according to usage. The service is ideal for any company that wants to upgrade to time stamping the easy way.

TC TimeStamp is ideally suited to protect signatures created using Algorithms considered weak in the near future. This kind of protection is required according to §17 SigV (German Signature Ordinance).
