Android system-based intelligent POS security system, starting method and data management control method

Abstract

The present invention relates to an Android system-based intelligent POS security system, a starting method and a data management control method. The system comprises an application CPU and a security CPU connected with the application CPU, the application CPU is also connected with a communication module, a display screen and an internal memory, and the security CPU is also connected with a touch screen, a contact IC card reader, a non-contact IC card reader, a magnetic card reader and a physical security circuit. According to the present invention, the transaction sensitive information, such as the bank encryption/decryption secret keys, the user ciphers, the account data, etc., is protected effectively, the contact of the sensitive data and an Android system is isolated effectively, at the same time, a signature verification mechanisms is provided to protect the integrity and the legality of the Android system and the APP programs effectively, thereby guaranteeing the payment security of the Android system-based intelligent POS.

Therefore, it is difficult for the smart POS built on the Android open system to meet the security requirements of the financial industry

[0005] Some smart POS products use customized Android system to enhance the underlying security of the operating system, prohibit Root, prohibit the installation and loading of unsigned APPs, and isolate payment-related applications from other applications to improve security, but Android operations will be lost System openness, scalability, and even user experience, the development and security certification cycle is long, and there are still inevitable security risks
