The Intelligent Protective Sysetm Based On Face Liveness Detection

With the development of technology and the progress of society,an increasing number of banks begin to promote the construction of intelligent banks,and a large number of new self-service devices are put into use.Although self-service devices have brought a lot of convenience to our life,there are also some problems come from them.When customers are using self-service devices,their information may be stolen and their security may be threatened.In order to protect the users' safety,self-service devices always be installed with protecting cabin.However,the function of the the traditional protecting cabins are too simple to realize real-time remote alarm and monitoring,record the appearance characteristics of criminals,and provide effective evidence for crime.Therefore,this paper proposes an intelligent protecting cabin system based on liveness-based detection technology.Compared with the traditional protecting cabin,the protective system has two main improvements: firstly,the connection between the bank and the protecting cabin has been built.With this system,the bank manager can monitor the protecting cabin operating states remotely.When the protecting cabin user is in danger,the system can also be used to send alarm signals to the remote monitors and make a Long Distance Speech with the monitor.Secondly,a liveness detection algorithm based on blink detection and similarity of background is proposed and applied to the entrance guard system of the protecting cabin.With this system,the door of the protecting cabin can be opened when users' s face was detected,and the facial image of the user can be stored in the bank database.The main work of this article is as follows:Firstly,aiming at the shortcomings of the current protecting cabin,an intelligent protecting cabin system with the function of remote interaction and liveness detection is designed.Based on the study of face liveness detection algorithms and the requirements of the subject,a new face liveness detection algorithm based on blink detection and similarity of background is proposed.Secondly,the management system of protecting cabin is designed.In this work,based on the system requirement analysis,the software development environment and programming language of the management system are determined and the database is built.The function of remote monitoring,remote alarm,remote parameters' adjustment,remote voice and remote video monitoring are designed.An administration function is added to manage the key points of the whole system.This system also has the information query function and the visual interface.Finally,the hardware and software are designed for the intelligent protecting cabin system.Based on the relationship between the external input,and the output of the equipment,the local control founction is designed to run the protecting cabin automatically.And the performance of the system is tested.
