A new method for evaluating cloud computing user behavior trust

Cloud computing is a model for networking universal, easy and on demand access to a set of computing resources that can be quickly interfering with minimum labor, or require the service provider to be provisioned. One of the issues discussed in cloud computing, is user behavior trust in cloud services. For trusted services and users´ satisfaction in the context of cloud computing behavior trust of each user should be assessed. Cloud computing subscribers, including members, local organizations and distributed resources should built trustworthy relationships among entities which are linked together. Relationships are based on trust. In this paper we proposed a new method for user behavior trust evaluation that considers user´s identification code and mac address to prevent the registration of members with multiple user names and makes available the information of user behavior trust in other cloud computing environments. Also, in calculating the amount of user behavior trust assigns a negative score for repeated disruptive behaviors. This method rely on the user behavior from the perspective of service providers in the 6-step measures and considers the new scores of user, behavior scores rated in the past, the scores of the other entities and scores of other cloud computing provider´s to the user. Principles are presented for calculating scores and total confidence to the end user is obtained as a score. The method helps identify malicious users and negative behaviors. Finally we compare proposed model with other models of user behavior evaluation that use principles and show the effectiveness of model in detecting malicious behavior and users.
