FIELD: information technologies.
SUBSTANCE: in invention they identify randomly distributed criteria of object, compress them and code them with the help of signature. Label is created, which contains object of authentication and coded data. Data may be compressed thus identifying function of probability density related to object of authentication. Vectors related to randomly distributed attributes are identified on the basis of at least partially probability density function. Vectors are coded with application of arithmetical coding algorithm.
EFFECT: reduced cost of objects manufacturing with high extent of data protection.
