dc.description.abstract With improved technology, every user now generates huge amount of data that requires ever increasing amount of space to store it. It is not economical for the users to purchase new storage device every time. As a remedy to this problem di erent service provider o ers storage space that can be utilized by the users. Cloud computing also provides a similar functionality to the users for storing their data over the Internet. The invention of cloud computing has ful lled the need for extra storage space but at the same time it has also lead to increased concerns regarding security of data stored over the Internet. The responsibility of the security of this huge amount of data lies with the service provider, but there may arise a situation where user may not trust the service provider due to the sensitivity of data. So there is a need of a technique which provide users a level of trust and security. In Document security solution (DSSol), we have tried to deal with such a situation, where we provide protection against adversary which can also be the service provider itself. We have used the Steganographic le system along with encryption to protect the document uploaded over the Google Docs from any security breach. The design encrypts the data les to be uploaded and divides them in equal sized chunks which gets uploaded along with some additional dummy chunks to the Goggle Docs. This provides unobservability, tra c analysis resistance and thereby providing protection against attacks possible due to tra c analysis and usage patterns. en_US
