A Method of Fingerprint Legitimacy Discrimination Based on Fuzzy Matching Algorithms for Terminal
Abstract— Nowadays, increasing number of network security events occur according to some illegal
terminal counterfeiting intruding into the enterprise's internal network. The traditional terminal access system
only uses some easy feature information (such as MAC address, IP address, host name, etc.) of the terminal
equipment as the admission certificate to judge the legitimacy of terminals. In this paper, a method based on
fuzzy approximate matching algorithm is proposed to identify the legitimacy of fingerprint features of
terminal equipment. This method combines the basic characteristics of equipment and the behavior
characteristics of equipment to generate device fingerprints, and uses the fuzzy approximate matching
algorithm to compare the similarity between device fingerprints and fingerprints recorded in fingerprint
database, so as to determine whether the device to be tested is a legitimate device. Finally, experiments show
that the accuracy of the algorithm is 94.5%.
