Design And Implementation Of University Student Apartment Management System Based On Compound Identity Authentication

College student apartment is an important place for college students,in where they live,study and rest.Actually,many college students spend almost half of their time in apartment.It's the basic duty of college to ensure the safety of dormitory.At present,most student apartment manage system implement identity authentication based on campus card or face recognition.However,with the development of imitation technology,the cost of cracking this single authentication method becomes lower and lower.There are security vulnerabilities in single authentication apartment management system.College student apartment management system proposed by this thesis is based on traditional access management system,and it integrates RFID technology,face recognition technology and WIFI probe technology to implements the"person-card-cellphone agreement" composite authentication strategy.The"person-card-cellphone agreement" composite authentication strategy prevents easy crack of single identity authentication,reduce the search range of facial features,and speed up the face recognition speed.In order to improve face recognition efficiency for large target library,in this paper,a hierarchical recognition algorithm based on facial stiffness geometric features is proposed.By this algorithm,the target library is classified into multiple patches and encoded by a small amount of facial stiffness features which are insensitive to illumination,expression and attitude.During the face recognition,the image is calibrated and encoded by the rigid characteristics,and the image matching is only in the corresponding patch.The classification of target library is not only helpful to reduce the computational amount of the match,but also to reduce the probability of similar face appearing in the training set,so as to speed up the recognition speed and improve the accuracy of recognition.The management system of college student apartment consists of managing client,server and mobile client.The management client is composed of industrial computer,image Acquisition unit,gate system,WIFI probe,emergency switch and other components,and it is responsible for collecting user information,completing identityauthentication,realizing control management of apartment entrance.Server stores and manages all user data.Mobile clients are developed by WeChat public accounts and users can upload their own facial images,cell phone MAC address,student ID,room number or other personal information by subscribing the WeChat public account or scanning the two-dimensional code with cellphone.The information of student is collected and stored in server,and then it will be download by the corresponding apartment manage client for authentication of the user's access to the apartment.By the mobile client,managers of the apartments can also send notices to users,such as lost and found information,water and power outage notice,visitors'information,or reminding users to sleep in time.
