In that case, the user wants to keep the secret of data and how to process the data. Even if the data and programs are encrypted, when data processing, the data and programs will be decrypted. So the cloud provider could look into the data and programs. Usually, between the user and the cloud provider shall contract to keep the secret. The contract is called SLA (Service Level Agreement). The cloud provider will honestly obey the contract. However, the user could not keep the mind in peace if he is in a sever competition. The user’s need is like “I will ask data processing but I would not like to be known what data exist and how the data are processed”. Is it possible? We propose a proposal to solve this need. The verification for this proposal is our future work. Keyword: Cloud Computing, Security, Opinions Gathering, Concealment of Data and Programs
