Unique Code Generation for Banknote Journal Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional money handling machines at banks face issues with counterfeited journals leading to inappropriate bank account payments and require a communicative connection for authentication, which prevents offline operation and increases costs.
Innovation Solution
Incorporating a unique code generation and printing mechanism on the journal to authenticate its authenticity, allowing offline operation and reducing costs by enabling the teller to verify the journal's authenticity without external connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a communicative connection between the money deposit machine and the upper-level terminal is established for authentication, then the reliability of preventing counterfeit journal payments is improved, but the device complexity and operational costs increase, and offline operation becomes impossible
Solution Approach 1:
The patent extracts the authentication function from the complex networked system and embeds it directly into the money deposit machine itself. The machine now contains an authentication unit with algorithms and reference data that enable it to independently verify journal authenticity without requiring connection to an upper-level terminal, thus reducing system complexity while maintaining reliability
Solution Approach 2:
The money deposit machine performs self-authentication by using its own embedded authentication unit to verify the journal's authenticity. The system serves itself by containing all necessary authentication components (algorithms, reference data, verification logic) within the machine, eliminating the need for external authentication services and enabling offline operation
2Difficulty of detecting and measuring
If a warning device is disposed near the money deposit machine to alert when counterfeited money is put in, then the detection of counterfeit money is improved, but the teller at the teller window may not notice the warning due to the distance between the money deposit machine and the teller window
Solution Approach 1:
The patent introduces the journal itself as an intermediary carrier of authentication information. Instead of relying on distant warning devices that may not be noticed, the authentication result (authentic or counterfeit) is embedded directly on the journal through unique codes or markers. The teller can verify authenticity by examining the journal at the teller window, ensuring the information is transmitted reliably regardless of distance
Solution Approach 2:
The authentication of the journal is performed in advance by the money deposit machine's authentication unit before the journal is delivered to the teller. The authentication result is pre-marked on the journal, so when the teller receives the journal, the authenticity verification has already been completed, and no additional warning detection is needed at the teller window

AI summary
The money handling machine (banknote depositing and dispensing machine 1) includes a unique-code generating unit 80 configured to generate a unique code that is used for a receiver of a journal in judging whether the journal is authentic or counterfeit based on at least a part or all of the deposit information printed on the journal by a printing unit (printer 6). The printing unit is configured to print on the journal the unique code generated by the unique-code generating unit 80 as well as the deposit information that is information regarding money deposited into the money handling machine.
