Trust Management is one of the most important factors for the success and adaption of the cloud computing. Cloud Services are distributed,non-transparent and highly dynamic in nature. These introduce more issues like availability,security and privacy. Trust management and consumers have interactions between them. These interactions may involve consumer’s information which is more sensible. So protecting consumer’s privacy is not an easy task. Malicious users may create problems for cloud services. In this paper,we are presenting a reputation based trust management model which consist of identity management which is used for the registration and list the malicious users. Trust management is used to take feedback of the user,provide the trust result of the cloud service and used to add the cloud services which are available in the internet. © 2016,International Journal of Pharmacy and Technology.
