ABSTRACT
Based on software system user historical access data, this paper studies user visiting access behaviors and habits, Through the construction of co-occurrence model of user behavior, the credibility calculation method of user behavior is proposed. The co-occurrence model of user behavior consists of co-occurrence probability matrix and synchronization distance matrix. These two matrices are still based on user history access data, through the data processing process, the behavior sequence data is converted into the form of matrix. The calculation method of user's behavior credibility is based on the above two matrices. This method can effectively quantify the trust degree of users' behavior sequences compared with their historical behavior habits by dividing the behavior confidence interval and setting the trust threshold. Finally, the simulation results show that the method is effective.
