introduction

Articles 1 and 7 of Chapter 1 of the Bills of Exchange Law of the People’s Republic of China, promulgated on May 10,.1995, clearly stipulate that. “In order to regulate Bills of exchange, to protect the legitimate rights and interests of the parties involved in bills of exchange, to maintain economic order, to promote the development of the socialist market economy, "And "the signature on the bill is a signature, a stamp, or a signature plus a stamp." Therefore, in the domestic economic and circulation fields, stamping and signature It is the only legal payment order for customers when using bills to settle funds. Due to the influence of Chinese historical and traditional culture, the use of bills for settlement in China The main method of payment is stamping. With the development of my country's economy, the volume of banking business has increased rapidly, and the amount of bills processed has become increasingly larger. The traditional bank seal verification method is that the bank teller folds the corner of the seal to be tested on the bill and compares the corner line with the corresponding position of the reserved seal. Manual positioning is performed and then the comparison is completed by visual inspection. This method leads to inconsistent verification standards, low verification accuracy, and difficulty in ensuring verification. If there is any misjudgment of quality, it will bring great economic and reputation losses to the bank and the customer. In terms of seal cards, there is a lack of safe, convenient and standardized management methods. At the same time, the verification speed is slow, the reserved seal cards are difficult to transfer, and the seals of bills between different places are difficult to pass. The authenticity of banknotes is very difficult to determine, and the inability to carry out corporate deposits and withdrawals has seriously restricted the development of banking business. In.2006, with the release of GB/T 20206-2006 “Technical Specifications for Banking Seal Verification System”, the banking seal verification technology was fully implemented. The reserved seal card is electronically archived and shared, which enables the network and remote location of the bill seal to be tested. Verification, completed the public business deposit and withdrawal processing function, in the check image system, reconciliation system, credit system, counter system, back-end centralized processing In short, the implementation of this document provides technical guidance for the business development of banks. First, ensure the security of fund settlement and control the occurrence of criminal cases; second, improve work efficiency and reduce operating costs. Summarizing nearly 20 years of experience in standard implementation, this revision further unifies design standards, algorithm performance indicators and implementation specifications, adopting a more Scientific and effective management methods, standardize seal verification technology, unify technical levels at all levels, and effectively ensure the security of bank funds settlement; formulate seal verification technology The technical requirements and evaluation contents of the verification also provide a basis for product liability insurance. In order to select better seal verification system products, it aims to provide more comprehensive evaluation basis and guidance for functionality, security and compatibility. The technical focus of this standard revision is. acquisition equipment, image processing technology, artificial intelligence algorithm, modeling quality control, and authenticity judgment. Continuous training, shared network management, system operating environment, and evaluation methods. Technical Specifications for Banking Seal Verification System
