Campus User Portrait System And Design And Implementation Of Access Control

Today,in the era of big data,the network environment is becoming more and more complicated,which has brought tremendous influence and even temptation to campus users.It also brings higher challenges and difficulties to the management of college users in campus.So for colleges and universities,through data mining and behavior analysis,to understand and help on-campus users accurately,is conducive to the implementation of effective management.In building campus user portraits,the privacy of campus users is made explicit,so access must be strictly and securely controlled to protect it.This paper uses the core technology of WEB development and visualization technology to design suitable dimensions and design the core model of research user portraits through the analysis of user characteristics and the characteristics of research campus users with dynamic and uncertainty.At the same time,in order to protect the privacy of campus users,an improved role-based access control model is designed and implemented.Improved role-based access control model based on the traditional role-based access control model.The permission controlled by the role only,changed into be controlled by either the role or the user via the access control list.The application effect in the system shows that the improved role-based access control model can realize that the roles and users can control the rights to meet user needs.It can provide environmental support for scientific management in colleges and universities.
