Identity authentication method and device for wearable intelligent equipment

Abstract

The invention relates to an identity authentication method and device for wearable intelligent equipment. The method and the device have the beneficial effects that on the basis of the principle of intra-body communication and in combination with the bioidentification technology, when users use the wearable intelligent equipment, S21 parameters after test signals flow through user bodies are acquired in a test frequency band to determine the optimal frequency band, the S21 parameters are acquired and processed in the optimal frequency band to obtain final authentication templates used for representing user identifies; authentication of the user identifies is achieved by comparing acquired user identity authentication data with the authentication templates; the privacy information of the users is effectively protected by utilizing nonreproducible uniqueness of the biological characteristics of human bodies and the advantages that the biological characteristics of human bodies can not be lost or forgotten and are difficult to counterfeit, thus well ensuring the privacy and safety of the users, avoiding potential risks caused when the users use the wearable intelligent equipment and being greatly beneficial to popularization and application of the wearable intelligent equipment.

Description

technical field [0001] The invention relates to the field of identity authentication, in particular to a method and device for identity authentication of a wearable smart device. Background technique [0002] In recent years, with the development of microprocessors, sensors and computer networks, the penetration rate of wearable smart devices among global users has continued to increase, and diversified wearable smart This field shows important research value and application potential. [0003] Wearable smart devices usually carry a large number of sensors to collect private information such as the user's health, hobbies, and schedules. These private information are very important to the user because they involve the safety of the user's personal and property and must be encrypted. protection against leakage. However, most of the wearable smart devices currently on the market do not have the ability to protect the user's private information that is detected and stored. A f...
