Patent KR-20000029683-A (KR)
Inventor: NEWMAN PETER A
IPC: G06F1/00
Filed: 1998-05-25
Abstract: PURPOSE: A copy protected record carrier is provided to do not rely on variations of physical parameters, to protect the making of usable copies on writable information carriers. CONSTITUTION: A method of a copy protected record carriers(1) are provided with a pattern of logical errors(2) which cannot be corrected by the error correcting rules predefined for the record carrier. The pattern of logical errors represents access control information. The logical errors are generated during decoding the bit sequence read from the record carrier. Bit errors is positioned in the bit sequence so as to counteract de-interleaving which is part of an error decoding process in a reading device and accumulate in error words which are uncorrectable. Also a method for detecting access control information and a retrieval arrangement are provided. The retrieval arrangement detects the access control information by selecting at least one error location, but not all error locations on the record carrier, and verifying the presence of an error by reading the selected error location via the reading means.

Abstract: PURPOSE: To decode ciphered data by using a cryptographic key communicated asynchronously with the ciphered data. CONSTITUTION: In a step S16, a control circuit monitors an ODD/EVEN flag added to encryption data. In a step S17, the control circuit decides whether the flag read in the step S16 differs from a flag read last time, and when the control circuit decides that the flag is changed, the processing continues to a step S18. In the stop S18, the control circuit discriminates whether the new flag is an ODD flag or an EVEN flag, and when the control circuit decides that the new flag is the ODD flag, and the processing continues to a step S19. The control circuit in the step S19 decides whether a key smaller in two keys described in a register is recorded in an EVEN register, and when the control circuit discriminates that the smaller value key is described in the EVEN register, the processing continues to a step S20. The control circuit in the step S20 causes the EVEN key described in the EVEN register to be updated.
