Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0032] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0033] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static rando...

Abstract

The purpose of the present invention is to provide a method and device for identifying user and device identity security based on sound waves. This application collects the input first voice password through the microphone of the source device, and saves it as a key password in the TrustZone security area after processing, which is convenient for follow-up The comparison of the input second voice password accurately identifies whether the identity of the user inputting the second voice password is legal. In addition, the source device matches the second voice password with the key password in the security area of ​​the memory, accurately identifies whether the identity of the user entering the second voice password is legal, and then encodes the voice password, and will include The source device identity information and the sound wave password using the source device's user identity information are sent to the target device, indicating the source device identity and the user's identity using the source device. The target device can use the microphone to receive the sound wave password, demodulate the source device identity information and user identity information, so as to safely identify the user and source device identity.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for identifying user and device identity security based on sound waves. Background technique [0002] Due to the popularity of smart devices and the era of Internet of Everything (IoT), the protection of personal characteristics (fingerprint, iris, voice) is very important. With the popularization of community culture, more devices related to social identity will be interconnected, and security will be the most critical part. [0003] Device-to-device information exchange is inseparable from the confirmation of identity information, and even the safety of the user who uses the device and the device, as well as the safety of the behavior of using the device is becoming more and more important. When we want to exchange information with another device, we must establish a secure information channel. The prerequisite for establishing a secure information channel is to provide a sec...
