Cloud computing ensures Cloud Information Accountability (CIA) framework, based on the notion of information accountability. Privacy protection technologies which are built on the hide-it-or-lose-it perspective, information accountability focuses on keeping the data usage transparent and tractable. CIA framework provides endto end accountability in a highly distributed fashion. One of the main innovative features of the CIA framework lies in its ability of maintaining lightweight and powerful accountability that combines aspects of access control, usage control and authentication. Their basic idea is that the user’s private data are sent to the cloud in an encrypted form, and the processing is done on the encrypted data. The output of the processing is deobfuscated by the privacy manager to reveal the correct result.
