COMPUTER-READABLE CARRIER WITH MICROPROCESSOR FOR CONTROLLING READING AND COMPUTER, ADAPTED FOR FORMING CONNECTION WITH SAID CARRIER Russian patent published in 2005 - IPC

FIELD: digital data storage devices.

SUBSTANCE: device is provided with memory area for storing data and separate microprocessor, having a communication interface, memory block and processor connected to communication interface, and also to memory block. Data may include first data portion, which is adapted for reading and decoding by a computer device, in case when at least one condition is fulfilled. Microprocessor is adapted for generation of at least one cryptographic key. Processor is made with possible realization of communication to computer device through communication interface for checking whether said condition is fulfilled, and for generation of said cryptographic key for mentioned computer device, if the condition is fulfilled. Also provided are computer device for communication with computer-readable carrier; method for reading and decoding data from computer-readable carrier; data carrier, computer software for realization by a processor of method for reading and decoding data from computer-readable data carrier; method for allowing access to data, stored on a computer-readable carrier; data carrier, provided with software for realizing method for allowing access to data, stored on computer-readable carrier; method for allowing access to data, stored on computer-readable carrier and system for providing for safe access to data.

EFFECT: reliable copy protection.
