ABSTRACT:
A system for digitally signing electronic documents is disclosed. The system includes a mobile device, an application server and a database, the mobile device includes a requesting module and a digest encrypting module, the application server includes an obtaining module, a digest generating module and a merging module. The requesting module is configured for sending a request for a digital signature of an electronic document to the application server; the obtaining module is configured for obtaining the electronic document from the database; the digest generating module is configured for generating a digest of the electronic document, and sending the digest to the mobile device; the digest encrypting module is configured for encrypting the digest, generating an encrypted value, and sending the encrypted value to the application server; the merging module is configured for merging the encrypted value and the electronic document. A related computer-based method is also disclosed.
