FIELD: computer equipment.
SUBSTANCE: invention relates to means for verification of bullet authentication. Computer device or its logic circuit takes, for example, through a camera or through a communication network, an image of a bullet-candidate, for example, one-dimensional or two-dimensional barcode, uses an image to perform measurements of the characteristic of attribute of bullet-candidate, as a result a profile for this attribute is created. Computer device filters, from the profile of attribute, all spatial frequency components, which are indicated as frequency components of sibling. In some embodiments, the computer device performs an inverse procedure and filters out all frequency components except those indicated as frequency sibling components.
EFFECT: high accuracy of identification.
