Implementation of the Software Lock Function Based on Fingerprint within Hardware

The common achievement method of software locks is studied,the design idea of identity certification that using the computer hardware internal fingerprint as software key is proposed.When development,the fingerprint information in user's hardware that distributed with the software need to be collected,and must be embedded into the internal program.When application,the fingerprint information in the specified hardware is detected automatically,and compare with the known fingerprint information embedded within the software,the key function of the software lock is realized.Practice shows that this method is designed simple,easy to use and can replace some dedicated hardware encryption devices to achieve higher strength identity certification effect.
