Digital Signature System for Electronic Documents is Patented

Software provider Xign has been awarded a US patent for a digital signature system. Issued to Xign on 19 October 2004, US Patent number 6,807,633 covers digital signature technology that verifies the authenticity, integrity, and security of electronic documents associated with the settlement of a business-to-business (B2B) transaction. Legacy digital signature systems have allowed document recipients to verify the authenticity of electronic documents; however, these systems are often difficult to use, do not support a variety of computing platforms, and require add-in cards or peripheral devices for interconnecting with other systems.
