DATA CARRIER, PROTECTED FROM UNSANCTIONED ACCESS, METHOD FOR PERFORMING OPERATIONS WITH SAID DATA CARRIER, PERSONAL DATA PROTECTION METHOD Russian patent published in 2005 - IPC

Abstract RU 2263967 C2

FIELD: data carriers.

SUBSTANCE: carrier has at least one memory, in which operation system is contained. Methods for performing data protection operations in data carrier with chip describe order of execution of aforementioned operations. Method for protecting personal data includes, prior to execution of one or more operations, concerning data protection, distortion of source data by combination via logical operation XOR with auxiliary data, and for compensation of aforementioned distortions, output data are combined via logical operation XOR to value of auxiliary function (F(Z)).

EFFECT: higher efficiency.
