  • Method of detecting changes to a collection of digital signals
    Patent number: 5448668
    Abstract: A probabilistic method of detecting viral intrusion into an original computer file is disclosed. In the method, a protection file is first created. In the preferred embodiment, the protection files is created by generating a test string. The test string is compared to the original computer file and is discarded in the event of a match. The test string is kept in the event of a non-match. The protection file is created by storing a plurality of non-matching test strings. In the detection stage, the file to be screened for possible viral infection is compared to each of the test strings of the protection file. The computer file being screened is determined to be probabilistically free of a viral infection if all of the test strings in the protection file do not match the file being screened. However, in the event of a match between a test string and the file being screened, then a change in the file being screened is detected.
