POS (point-of-sales) safety certification device, POS safety certification system and POS device safety certification method

Abstract

The invention discloses a POS (point-of-sales) safety certification device, a POS safety certification system and a POS device safety certification method. The POS safety certification device comprises a safety certification information acquisition module, a certification information communication module, a master control module and a data channel safety control module; the safety certification information acquisition module is used for acquiring safety certification information of a user; the certification information communication module is used for transmitting the safety certification information of the user to a bank server to perform safety certification and receiving returned safety certification data; the master control module is used for generating a data processing result according to the safety certification data; the data channel safety control module is used for controlling data exchange between the POS safety certification device and external equipment according to the data processing result. The POS safety certification device, the POS safety certification system and the POS device safety certification method have the advantages that satellite positioning information acquisition, registration and safety certification verification for relevant devices and the equipment are implemented, a biological feature safety authentication verification function is realized for POS safety certification, the safety of the POS safety certification is effectively improved, leakage of a password of a client is prevented, and the client can immediately make a safety payment via a mobile phone locally.

Description

technical field [0001] The present invention relates to the field of information security, in particular to bank POS device security technology, specifically a POS security authentication device, system and POS device security authentication method. Background technique [0002] With the rapid development of information technology, mobile payment has become popular. In order to ensure the safety of mobile payment, the current method of mobile payment is usually divided into three steps. First, the customer signs a contract with the bank to open the mobile payment service, and completes the registration and authorization of the binding of the mobile phone card number with the bank account; Before payment, the customer sends payment request information with simple payment password security authentication information to the bank's mobile payment security authentication system through the mobile phone; finally, the bank's mobile payment security authentication system performs se...

AI Technical Summary

Problems solved by technology

[0003] However, with the proliferation of mobile phone Trojan horse viruses and the malicious detection and illegal use of mobile phone operating system security vulnerabilities, there are obvious technical security risks and functional defects in the prior art mobile payment methods.

First of all, under the existing technical conditions, the satellite positioning and geographic location information of payment mobile phones and other key payment control equipment is not timely and securely verified, and it is easy for mobile phones and other related wireless devices and key payment control equipment to be illegally embezzled or illegally connected to the payment service network network and other crimes, causing heavy losses

Secondly, the existing mobile payment technology does not carry out security authentication and verification of the legality, authenticity, and biometric characteristics of the payment mobile phone and the electronic certificate holder, and there is a security risk of only authenticating passwords and certificates but not authenticating people and equipment.

Furthermore, the existing mobile payment technology only focuses on the authentication of the legality of the mobile phone holder's business authorization, and fails to realize multiple security authentications of merchant POS electronic certificates, people, systems, and equipment that play a key role in merchant charges. It is also not possible for mobile payment customers to use QR codes to pay electronic license certificates at the shopping site for independent confirmation of payment and on-site audio and video evidence collection, which is prone to counterfeit payment or transaction repudiation by customers

[0004] Therefore, the existing mobile payment not only has some functional deficiencies, but also the security of mobile payment and POS payment is poor, there are obvious hidden dangers of technical security and information leakage, and it is easy to cause transaction denial and counterfeiting and illegal key payment control facilities. The promotion of mobile payment encounters serious difficulties
