Method for authenticating identity of mobile terminal and constructing safety channel

Abstract

The invention belongs to the field of identity authentication and image recognition, and specifically relates to a method for authenticating identity of a mobile terminal and constructing a safety channel. The method comprises the steps of 1) authenticating the identity, namely, mutually shooting by two data transmission sides through a front camera and a rear camera of an intelligent terminal, extracting the characteristics values of the image shot by the front camera of a first user and image shot by the rear camera of a second user, performing image matching for the first time, and entering the next step after successful matching; 2) constructing the safety channel, namely, generating a random key according to the background noise of the image shot in step 1), constructing a temporary channel through the random key, and then constructing the safety channel on the basis of the temporary channel by the Diffie-Hellman key exchange method. The communication channel constructed by the method is stable, safe and high in effectiveness; the identity can be authenticated and the safety channel can be constructed simply by shooting the images; the method has the advantages of being safe, efficient, convenient and fast and can be generally applied in the field of mobile data transmission for a long term.

Description

technical field [0001] The invention belongs to the field of identity authentication and image recognition, and in particular relates to a mobile terminal identity authentication and a method for establishing a safe channel. Background technique [0002] With the rapid development and prosperity of the mobile Internet, the demand for data transmission on mobile devices is growing faster and faster. In this context, mobile data transmission technology has been developed at an unprecedented high speed. In the era of information explosion, personal privacy is constantly being leaked in various ways. How to protect personal privacy and data security is an issue that has to be considered. On this basis, regardless of whether the data transmission on the mobile device side uses Bluetooth, WIFI or NFC, the data must be transmitted to the correct user and must be transmitted to the user safely. In short, the bottom-level requirement for data transmission is correct identity authen...

Problems solved by technology

Limited by the performance of mobile devices and network conditions, the generation and distribution of public and private keys will be very cumbersome, which will inevitably slow down the process of establishing encrypted channels, and the increase in time is also intolerable for mobile data transmission
