Cloud Computing is a flexible, cost-efficient, and authentic platform for providing business or consumer IT enabled services on the Internet. However, Cloud computing represents an added level of risk factors because important and essential services are often outsourced to a third party connected to cloud network, which makes it even harder to maintain the level of data security. Steganography is the technique of hiding or encapsulating information in digital media in order to prevent the existence of information. The digital media with hidden information within are called stego media and the data without hidden information are called cover media. Steganography can be used for hiding both the legal as well as illegal information. For example, civilians can use it for maintaining privacy while the government may use it for the security reasons of the country. In this paper we have discussed about the various techniques by which we can enhance the cloud service in relation to security and data privacy.
