FIELD: information technologies.
SUBSTANCE: method is implemented by introducing the person's attitude taken when the person is affixing a signature (autograph) by controlling that attitude. The person's attitude is represented in the form of a 3D-curve containing the sections built as per average points of a 3D-figure consisting of a feather, upper limbs and shoulder girdle of a person. The obtained curve is converted to digital form by using chain-line coding in projection planes of vertical, side and frontal person's images.
EFFECT: increasing accuracy of person's authenticity as to his biometric image owing to more complete use of biometric information characterising the person when the person does not know that the check is performed, and when it is not necessary to teach biometric control system for many times.
