METHOD FOR PROCESSING INFORMATION FOR DETECTING IDENTIFICATION SIGNS IN INFORMATIONAL STREAMS Russian patent published in 2006 - IPC G06F17/30 

FIELD: computer engineering, possible use in devices for controlling informational streams to monitor informational traffic.

SUBSTANCE: method includes preliminarily forming a base of standard informational signs, receiving informational stream, serially selecting and recording fragments of informational stream, selecting identification signs from these, comparing them to standard ones. Base of standard informational signs is formed by computing morphological coefficient d of identification sign and its address A with utilization of hash-function. For identification signs received from informational stream, morphological coefficients d and identification addresses A are additionally computed, after that on basis of computed address, identification sign selected from informational stream is compared to standard one.

EFFECT: increased information processing speed due to shorter time needed for identification of addresses of signs in base of standard informational signs.
