This is a solution for public administrations, banks and companies for signing documents and verifying signatures on documents via web. The system can be easily integrated with other information systems used by operators and the staff using the e-commerce payment paradigma (chart in the original site, user transferred to UniServ WebSite for signing, return of the signed documents to the original site). Using the web architecture, the operator can use only the standard browser on his PC. The system therefore doesn't require maintenance or installation on individual clients. The functions available:

• Document signature
• Signed document retrieval
• Signed document verification
• Extraction of information from a certificate
• User authentication from a certificate
• Document timestamping
• Verification of a timestamp on a document
• Certificate renewal

can be used for any type of documents and dimension.
