Problems solved by technology

However, it has not yet solved the problem of using video or dynamic pictures to record face information to crack, nor can it solve the unlocking between twins or people who look similar or have been disguised by makeup, which still has a great security risk

Abstract

The invention comprises an intelligent terminal face unlocking method combined with gesture recognition. Firstly, the unlocked video image is collected and preprocessed. Then the image is processed byan Adaboost algorithm based on Haar features. After filtering, feature extraction and feature dimension reduction, the feature is extracted by a support vector machine SVM for face recognition. Aftersuccessful face recognition, the salient map of gesture region is established, and the Hu moment feature and HOG feature are extracted and fused to carry out preset gesture recognition. If the recognition is successful, the screen is unlocked, and the recognition failure is counted to reach the set number of screen locks. The invention integrates the visual recognition advanced technology such asface and gesture, improves the complexity of face unlocking, greatly reduces the success rate of cracking the terminal by using the methods such as video recording or dynamic picture recording without knowing the specific expression action, and also can not unlock the screen.

Description

technical field [0001] The present invention relates to a technology for unlocking a terminal screen, in particular to a face unlocking method for an intelligent terminal combined with gesture recognition. Background technique [0002] According to the analysis in the "2017-2022 China Smartphone Market Supply and Demand Forecast and Investment Strategy Research Report", the penetration rate of smartphones in my country has reached 58%, and smartphones have become an important channel for people to shop, communicate, study and work, and surf the Internet. A large amount of privacy data of users is stored in the mobile phone, such as photos and videos, office documents, consumption records, medical and health data, etc. If these data are leaked, it will inevitably lead to the loss of personal work, life and even economic property. As a portable device, mobile phones are easy to lose or be stolen by others. Therefore, how to prevent the disclosure of sensitive information in m...
