The Crypto-Sign Solution Crypto-Sign offers a new approach to electronic signatures to enhance the security of remote, web-based and wireless transactions and to generate significant economic savings. It is a patent-pending technology which combines the benefits of the PIN /Password with those of electronic signature verification to utilize the benefits of, and eliminate the disadvantages of both systems. Its author, Rod Beatson is the founder of Transaction Security and the author of the associated patent application. Crypto-Sign is essentially a non- invasive, low cost, software-based biometric solution to the problem of providing secure access control to remote devices and identifying remote authors of electronic messages and transactions.

Conventional Signature Verification Systems With the introduction of the Electronic Signatures In Global and National Commerce Act (the “E-sign” Act) an electronic signature is essentially any sign submitted electronically by the author signifying intent. This could be achieved by the submission of a password, which might release a private key to generate a digital signature to “sign” the document. Alternatively the author might submit a biometric sample to be identified by the system and hence generate the electronic signature

In the field of biometrics and particularly that of dynamic signature verification there is a belief that the submission of one’s signature on a digitizer, enabling the analysis and comparison of that signature against a previously generated template would provide a secure method of tying an electronic document to the author and give the ensuing transaction a high degree of integrity. Biometrically identified documents and transactions, using dynamic signature verification have been used in a variety of applications from the early 1980’s. Applications include cash withdrawals from retail bank branches, change control of engineering drawings, entry control to Safety Deposit boxes, identification of customers using credit or charge cards at retail point-of-sale and a number of others.

Today there are two main forms of dynamic signature verification systems. One system captures and processes pressure and force/acceleration signals sensed by a special pen as it moves over the writing surface.

The other dynamic signature verification system uses a digitizer, Tablet PC or Personal Digital Assistant (PDA) as the capture instrument and works in the following manner:
