A method and system for identifying counterfeit banknotes based on a smart phone

Abstract

The invention provides a smart mobile phone-based counterfeit banknote identification method and system. The method includes the following steps that: image information of a banknote is acquired, and image information of the banknote at different angles is acquired; the image information of the banknote at different angles is pre-processed, so that preprocessing results can be obtained; the watermark and invisible numerical denomination anti-counterfeiting features of the banknote are subjected to region segmentation, and segmentation results can be obtained; matching identification is performed on the segmentation results and the anti-counterfeiting features of genuine banknote template image information, and whether the matching identification is successful is judged; if the matching identification is successful, optically variable ink feature detection identification is performed on the image information of the banknote at different angles, and detection identification results are obtained, and the authenticity of the banknote can be judged according to the detection identification results; and if the matching identification fails, the banknote is identified as a counterfeit banknote. With the smart mobile phone-based counterfeit banknote identification method and system provided by the embodiment of the invention, the accuracy of counterfeit banknote identification can be improved, and counterfeit banknotes can be identified whenever and wherever, and user experience can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of counterfeit banknote identification, in particular to a smart phone-based counterfeit banknote identification method and system. Background technique [0002] Large amounts of counterfeit money in circulation can cause economic problems such as inflation.

Problems solved by technology

[0003] With the advancement of science and technology, the counterfeiting technology of banknotes is also increasing day by day. It has been difficult for people to identify the authenticity of banknotes with naked eyes or simple infrared counterfeit banknote detectors as before; The authenticity of banknotes can be quickly and quickly identified, but large-scale counterfeit banknote detectors are too bulky, heavy and expensive, and ordinary residents cannot afford such counterfeit banknote detectors, and it is not conducive to users to carry them around, so it is inconvenient for people. Use them to detect the authenticity of banknotes; so now people are in urgent need of a counterfeit banknote detector that is both convenient to carry and has a high accuracy rate
