Example Embodiment

[0046] Example

[0047] In this embodiment, the smart terminal is illustrated by a smart TV. The method applied to the smart terminal for payment based on TEE and blockchain includes a user registration method and a user payment method. The preparations include: user downloading or pre-setting the client , The smart terminal initializes resources and completes the client installation.

[0048] Specifically, the user registration method includes the following steps:

[0049] S101. The client sends a registration request to the TEE module when the user needs identity registration;

[0050] S102. The collection unit requests to collect the biological characteristics of the user;

[0051] S103. The user provides biological characteristics;

[0052] S104. The collecting unit extracts the collected biological characteristics to obtain biological characteristic information, and stores the biological characteristic information in the storage unit;

[0053] S105. The block chain unit encapsulates...

Abstract

The invention relates to the technical field of security, overcomes the problem that payment is unreliable when sensitive data is maliciously tampered by a third party in the existing payment process,and provides an intelligent terminal for payment based on a TEE and a block chain, the intelligent terminal comprises an REE module and a TEE module, and the REE module comprises a client for interacting with a user; The TEE module is used for collecting identity identification information after receiving the registration request, storing the identity identification information and carrying out cryptographic processing to obtain a ciphertext of the identity identification information; After receiving a payment request, calling a security input unit for a user to input payment information, comparing the acquired identity identification information of the user with the stored identity identification information, if the comparison is successful, sending the complete payment information to aclearing center, and after receiving a clearing success message, generating a corresponding payment log; And packaging the ciphertext and the payment log of the identity identification information according to a block chain protocol, performing local recording, and sending the local recording to a block chain network for linking. The method is suitable for safe payment of the intelligent terminal.

Description

technical field [0001] The invention relates to the field of security technology, in particular to a smart TV and a method for payment based on a trusted execution environment and a block chain. Background technique [0002] The operating systems of existing smart terminals basically run in REE (Rich Execution Enviromnet, multimedia execution environment). Rich OS (Rich Operating System, multimedia operating system) is usually an Android system or an Apple iOS system running in a REE environment. The REE There are security issues in itself. In order to ensure users' convenient, fast, safe and reliable payment transactions, GP (Global Platform, the global platform organization), the standard organization for smart cards and terminal security, proposed the concept of TEE (Trusted Execution Environment, Trusted Execution Environment). TEE is an operating environment that coexists with REE on smart terminals. TEE is a trusted execution system that is more secure than REE and is ...
