Privacy Enforcement on Subscriber's Data in Cloud Computing

Data stored in the cloud are susceptible to any array of threats from hackers and also to undetectable and unauthorized access by the cloud service provider. This is because the subscriber has no access to the internal operations of the cloud and cannot control access to his data. Therefore confidentiality, availability and integrity of subscriber's data must be maintained to gain their trust in cloud-based systems. This work made use of privacy with non-trusted provider algorithm to ensure privacy of subscriber's data. here, the subscribers encrypt their data before sending it to the service provider that performs a second encryption before storage in the cloud. Simulation was done on the multimedia dataset downloaded from Stanford University dataset. The systems results were then compared with an existing system using a trusted cloud provider and it ensured a higher level of privacy on subscriber's data.
