A PKI Based Digital Eye-Control Sign Technology

摘要

Security is very important in E-business. Nowadays, some kinds of digital signature devices have been used in different fields. But. Most of their authentication information are just PIN (Personal Identification Number), and lack of user's personal characteristic information. So, the data security can not be guaranteed very well. In our prototype system, the authentication information is composed of a cipher key based on the PKI (Public Key Infrastructure) and a digital eye-control signature. Then, the authentication information contains more personal characteristic information. At the same time, the system security is also be enhanced. The algorithm about how to discriminate the digital eye-control signature is also presented.
