Cloud Computing has been shows their importance in the next-generation architecture of IT Enterprise. It gives centralized large data centers with collection of application software and databases, but in which services offered by the cloud providers may not be fully trustworthy. This leads about many security issues, which gives a challenging work to researcher. Till the date researcher still working to give solutions to such security challenges raised in cloud computing environment. One of the challenge is having confirmation about deleted data. In the traditional cloud environment clients storing the data in the cloud servers and paying as per the agreement did for only the time they use. After the data uploaded in the cloud servers, the client which are the data owners can see the data are properly stored or not in the cloud servers. It is also makes important that data stored in the cloud will be in encrypted format because either public cloud service providers or the other users storing data on the same server are not trusted. With the encryption of data now a days a new problems arises about the deletion of data. As user deletion will work with one-bit-return protocol: deletion program delete the data and comes with one bit answer as success or failure. This one-bit-return protocol turns the system as black box, where user needs to trust on cloud provider about deletion of data. In this paper we are presenting the data deletion process more transparent, secure and verifiable. In our proposed system we will ensure that faithful deletion of data. We also proposed the correct implementation of the data with ensured deletion of all related keys.

Cloud Service Provider, faithful deletion, verifiability, encryption
