METHOD, DEVICE AND INFORMATION CARRIER FOR CONFIRMING ACCESS RIGHT TO AUTONOMOUS RESOURCES Russian patent published in 2007 - IPC G06F21/20 G06F12/14 H04L9/28 G07F19/00 G06K19/00 

FIELD: automatics and computer science, in particular, identification means for controlling access to autonomous resources.

SUBSTANCE: method includes changing identification information during each new query of autonomous resource, which information is used for identification of carrier during following queries to autonomous resources, by including it in algorithmically converted form on information carrier and in database of central device and checking of its correspondence in a row of previous queries to autonomous resources. Each autonomous resource has memory block for storing conversion algorithms and signs of these algorithms and block for reading/recording carrier information. Central device contains at appropriate data bank addresses the virtual memory blocks for storing information for identification of carriers and memory block for storing a set of algorithms for converting code from one type to another and signs of these algorithms, and for each carrier - information storage address which was used during previous accesses. Carrier contains energy-independent additional memory block for recording, storing and reading additional information code after identification of carrier, available both during manufacture of carrier and its submission to autonomous resource.

EFFECT: increased level of protection from unsanctioned access.
