FIELD: physics.
SUBSTANCE: database of users allowed to access a system is formed from sampled and quantised readings of handwriting samples of a matrix of two-dimensional discrete Haar transform coefficients. When allowing a new user into the system, a matrix of two-dimensional discrete Haar transform coefficients similar to the reference sample is formed from the sampled and quantised readings of handwriting samples 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 systems requiring use of personal identification means.
