E-signature based on PKI authenticates users, prevents denial, and secures integrity of documents. This technology satisfies the conditions required for non-facing e-commerce. But it does not certifies the real time of e-documents.
MagicTSA executes e-signature on trustworthy time-data, and issues digital time stamps that certify the existence of documents or data at specific time. Digital time stamp prevents false alteration of the time when data or documents are made. Also, it certifies the accuracy and genuineness of data.
Visual information about documents or data certifies transaction in e-commerce, and secures whole system. Especially, application services like e-contract or e-tender apply time certification service, because time of contract or tender is crucial for them.
