Cloud computing enables sharing of data over internet, hence the chances of security attacks also increases. So for the security of Data Sharing or Resources Allocation various Trust Models are implemented which provides security from various attacks. One of the efficient and improved Trust Model is implemented which increases the strength of Security in Cloud Computing [1]. Here in this paper various Trust Models their advantages and limitations are analyzed and com pare on the basis of various parameters. This paper deals with the analysis and survey of all the techniques implemented for Cloud Security so that on the basis of various issues a new and efficient Trust Model is implemented in Future.

Abstract: Cloud is a major requirement for data storage and computing power, without user direct performance. Cloud computing is a famous option for IT industries, enterprises, and government sectors because it provides everything as a service based on user demand. Cloud computing is a better environment for handling a large amount of data which is produced by social networks, health industries, transactional, etc., However, cloud has some issues during the data transaction, many researchers have proposed models and solutions for these problems but still maintaining consistency during the transaction is the biggest problem, it is one of the important properties in ACID. Further, secured architecture is another important issue in cloud environment. So this paper proposes a secured architecture and efficient D1FTBC approach for cloud data transaction. The performance analyses are evaluated at various levels. This research work may lead the transaction processing applications like banking, online reservations and shopping cart etc.,
