Cryptomathic Granted New Patent for Strong Non-Repudiation with eSignatures
October 2017 by Marc Jacob
Cryptomathic has been granted a new global patent (KR20170005400 (A)), which defines a method and system for generating an eSignature with the highest level of non-repudiation.
The patent relates to delivering a true What You See Is What You Sign (WYSIWYS) experience when users digitally sign documents remotely. The WYSIWYS term was coined by Cryptomathic founders in the late 90s, and focuses on being able to demonstrate that users only sign authentic documents, i.e. that the document has not been tampered with during the signature process. Together with the users’ sole control of their signature keys, WYSIWYS is central to the process of ensuring non-repudiation. Cryptomathic Signer delivers WYSIWYS technology and is used as a versatile remote signature server to sign documents and transactions at the qualified level in accordance with the eIDAS regulation.
The What You See Is What You Sign concept was invented by Cryptomathic all the way back in 1998, to enhance the security of digital signatures – and is one of the unique attributes of Cryptomathic Signer. Today’s patent announcement extends Cryptomathic’s IP portfolio in the digital signature space, and reconfirms its leadership in eSignature identity assurance together with its capacity for innovation in cryptography.
