FIELD: information technology.
SUBSTANCE: database of users allowed to access the system is formed from discretised and quantised readings of samples of the handwriting of a matrix of two-dimensional discrete cosine transform (TDCT) coefficients. When allowing a new user into the system, a matrix of TDCT coefficients similar to the reference sample is formed from the discretised and quantised readings of samples of the handwriting of that user. Comparison is carried out and a decision is made to associate the obtained record to one of the reference records.
EFFECT: high reliability of authorised access in all systems requiring use of personal identification means.
