Digital signatures have become part of everyday life. Signatures are used in online invoicing, online registry court administration and e-government services, which are available for everyone. In corporate environments signatures are used in document management, archival and tracking systems. Furthermore, signatures are widely used for protecting electronic correspondence.
A digital signature is special code which can be used as proof of who created which document. Adding timestamping capability extends this functionality with proof for exact time. We have significant experience in building PKI infrastructure, timestamping service and even in developing custom applications over digital signatures.
