An identity authentication method and system

Abstract

The present invention provides an identity authentication method and system. The identity authentication method includes: transmitting electromagnetic waves of different frequencies to an object to be identified, and acquiring a plurality of S parameter; filter the S parameter and perform feature extraction, obtain at least one of the amplitude information, frequency information and phase information in the S parameter, and form a test set; use the S that contains n known objects The training sample set of parameter information trains the support vector machine classifier to generate a recognition model that includes n categories, each of which includes all S parameter information of a known object, where n is a positive integer; using the The recognition model recognizes the test set, and if the output result of the recognition model is one of the n categories, the object to be recognized passes the authentication. The authentication and identification of human body identity can be realized quickly and accurately by using the invention.

Description

technical field [0001] The invention relates to the technical field of biometric identification, in particular to an identity authentication method and system. Background technique [0002] As wearable devices and the Internet of Things continue to heat up, wearable computing applications and industries have increasingly broad prospects, and are expected to become the next economic growth point in the world. [0003] Privacy security is a key technology in the development of wearable devices. Wearable devices carry various sensors that can collect personalized and private information related to people, such as medical and health data, sports information, and hobby information. With the development of mobile Internet technology, the probability of information leakage is increasing day by day, and the degree of harm caused by the transmission of private information is immeasurable. Therefore, the information privacy protection of wearable devices has become very urgent and n...

Problems solved by technology

[0013] It can be seen from Table 1 that, in addition to some deficiencies in the recognition rate and other aspects of the above-mentioned biometric recognition technology, when applied to wearable devices, there are generally disadvantages such as poor wearability and need to exist in a fixed part of the body.

Therefore, the existing biometric technologies are not suitable for wearable applications
