Method for verifying banknote origin, relevant device and system

Abstract

The invention discloses a method for identifying the source of bank notes, which comprises the following steps: the original information and the information of a transaction object of a transaction bank note are acquired, and the original information comprises infrared original information; identification characteristic amount is generated according to the original information; the transaction is finished, and the information of the transaction object and the identification characteristic amount of the transaction bank note are stored according to transaction results; the identification characteristic amount of the bank note to be identified is acquired; the identification characteristic amount of the bank note to be identified is compared with the identification characteristic amount of the stored transaction bank note, and the source of the bank note to be identified is acquired. The invention also discloses a device for identifying the source of bank notes, a device for identifying the authenticity of bank notes, and an automatic teller machine containing part of the devices. Because the infrared identification characteristic amount is used as matching information, the uniqueness of the identification of true bank notes and false bank notes is improved, and the accurate rate of the source identification of bank notes is effectively improved.

Description

technical field [0001] The invention relates to the field of banknote circulation and identification, in particular to a method for verifying the source of banknotes, a related device, a system and an automatic teller machine including the related device. Background technique [0002] The use of automatic teller machines (Automatic Teller Machine, ATM) to store or spend banknotes does not require the direct participation of counter staff, and the deposit and withdrawal of banknotes can not be limited by time and space. The demand for high-security banknote identification technology is increasing day by day. [0003] Although the current automatic banknote recognition technology has a high recognition rate, the production technology of counterfeit banknotes is becoming more and more sophisticated, especially the counterfeit banknote production technology for the loopholes of machine identification technology emerges in an endless stream. Therefore, the ATM is likely to cause...

Problems solved by technology

For example, in technologies that only use serial numbers of banknotes to identify banknotes and verify their origin, since most counterfeit banknotes have the same serial numbers as genuine banknotes, the existing methods of verifying the origin of banknotes cannot identify genuine banknotes with the same serial number and counterfeit currency, and the inability to identify multiple banknotes with the same serial number, i.e. the identification of each banknote is not unique (regardless of whether it is genuine or counterfeit), which may result in the inability to verify the exact origin of the banknote
