Abstract: “Cloud computing has recently emerged as a buzz word in the distributed computing. Today the issue of trust is one of the biggest obstacles for wide usage of cloud computing. When the element trust is absent in a cloud computing environment then this computing model will face a lot of challenges. One of the most important factors for the successful deployment and usage of cloud computing is to build trust and security in a cloud. Here the user directly operates the software and the operating system, so the effect and damage of the cloud resources are worse than that of the internet. Therefore, it is necessary to evaluate whether the user is trustworthy or not. In this paper, we have discussed feasibility of trust in cloud computing, which can be possible through building a trust model for evaluating user-level trust in cloud computing environment. We have further explained the approach and principles for the evaluation of user trust in cloud computing. Finally we laid down the foundatio”
