About Crypto-Sign®

Crypto-Sign® is a non-invasive biometric technology, based upon electronic sign verification and signature capture. It combines the benefits (and eliminates the disadvantages) of the Password/PIN and traditional biometric signature verification systems as a means of remote user authentication. In application the technology requires the submission of a secret sign (no display or inking) on a PDA or digitizer, which is statistically compared to a previously established template for the sign.

Crypto-Sign® Applications range from remote access control to networks, web sites, files and electronic documents to secure document signing for proof of authorship and delivery. It is ideal for secure storage, access to and retrieval of electronic documents from electronic vaults and, with the advent of the Net enabled wireless PDA, for conducting secure document-based transactions and M-commerce from these devices. It would be an ideal technology to work in conjunction with an authentication server based service, using wireless PDA’s or wired PDA’s connected to Workstations or Laptops, where the pen-based hardware means of biometric input is already included. Based upon a business model of software licenses per PDA/Workstation, the ROI to enterprises installing Crypto-Sign® products is phenomenal.

Biometric Performance is a key area of product differentiation. Through his original Sign/On signature verification product, Mr. Beatson’s pre-Crypto-Sign® signature verification algorithms have been positively evaluated by Sandia National Laboratories and compare favorably with better-known biometric systems such as fingerprint, facial recognition and voice recognition. With the added secrecy afforded by Crypto-Sign® the FAR/FRR performance, security and user friendliness is significantly enhanced above the original Sign/On product.

Crypto-Sign® Development Status
TSI first developed a Win 32 based Crypto-Sign® system using sign input from an off-the-shelf digitizer. This ported easily to the Pocket PC 2002 platform and a PDA Crypto-Sign® demonstration system is now available for these devices. TSI’s first product, PDA-Protect®, extends the demonstration system to protect access to the PDA and its data by interrupting the Password request process. PDA-Protect was Beta tested by Microsoft and is now released. Please see the PDA-Protect page for product details and ordering information.
