Digital timestamps

Electronic time stamps can provide proof of integrity and completeness simply, legally, permanently, inexpensively and anonymously if required. A time stamp signature is thus an electronic certificate that has existed like a notarial deposit in court and confirms the authenticity of the digital content and the authenticity of the author.

Electronic documents with a time stamp can be checked for validity over a long period of time.

Add timestamps to certificate-based signatures

The signature software Sign Live! CC creates time stamps in documents or adds time stamps (date and time of signature) to certificate-based signatures. Time stamps are easier to check if they come from a trusted certificate from a certification authority. With time stamps you keep track of when the document was signed. This reduces the risk of an invalid signature. You can obtain the time stamp from certification authorities (USA) or at another issuing office for time stamps. 

Note: If no time stamp was embedded when the document was signed, it can be added with Sign Live! CC to be added to the signature later (LTV-Signature). A timestamp inserted after the document is signed uses the time specified by the timestamp server.
