Fake web addresses and hyperlinks

摘要

A destination address is processed to determine if the destination address is a fake web address or hyperlink. The destination address may be compared with a database of known domain names to see if the domain name is legitimate or illegitimate. The designation address may also be compared to other domain names to see if it is an honest or dishonest transformation of the other domain names. Appropriate action may be taken if the designation address is a dishonest transformation of another domain name.

主权项

1. A computer-implemented method of processing a destination address, the method comprising:
receiving, within a computer hardware device, the destination address; determining that the destination address is a domain name; comparing the domain name with a database of legitimate domain names; determining that the domain name does not match an entry in the database of legitimate domain names; analyzing the domain name to determine that the domain name is a dishonest transformation of a legitimate domain name by determining a similarity value between the domain name and the legitimate domain name exceeds a predetermined value, the similarity value being based upon a longest common subsequence between the domain name and the legitimate domain name; classifying the destination address as a fraudulent address; and taking an appropriate action in response to classifying the destination address as a fraudulent address.
