In cloud computing, resources are share among multiple clients and it is important for cloud service provider to allocate these resources for such clients. Cloud computing is an infrastructure that provides on demand network services. In this technology, user fears about loss of his own personal data. To solve this problem, we propose data accountability approach which is used to keep track of usage of user’s data in the cloud. We create JAR programmable files to ensure user’s data authentication and automated log in JARs. Using this mechanism owner may know his data is handled as per his requirement only. By auditing method, we can ensure that the information which was stored in the cloud is used by the responsible persons as per the service level agreements. In this paper, this distributed accountability concept is applied to generic file types which contain not only image data type but also all types of data. It also supports different variety of security policies, like indexing policies for text files, usage control policies for executable files. It describes an application, which maintains log records of data usage stored on cloud. It also provides strong protection to owner’s data by compiling jar of that file.
