Information carrier is printed or pressed with points, lines,
graphics, texts or combination of them, which not only has the only characteristic information, but also has information recorded with characteristic information (namely self-certification information). The method includes: printing points, lines,
graphics, texts or combination of them on the information carrier, using an
image acquisition instrument to read related characteristic information such as microscopic veins, tablet configuration, gaps surrounded by flaws or veins presented by
printing ink or dry toner inside the
image acquisition instrument, converting the characteristic information into another information expression mode, namely self-certification information, and denotes on the pressed points, lines,
graphics, texts or combination of them on a same information carrier; when identification is required, the characteristic information and self-certification information on the anti-counterfeiting products can be read by the
image acquisition instrument, performing
internal conversion according to the regulation, and then judging whether the two information is coincident in artificial or automatic mode, if coincident, the characteristic information is true, otherwise it is false. The invention has advantages of low cost, capability of large-lot production, capability of easily and accurately identifying, and application in all fields. The counterfeiters can not effectively imitate.
