Description

The problem of data anonymity is one of the most important aspects of nowadays’ data management systems. The main concern of users that want to store data over a cloud or over any distributed system from the internet is that their privacy needs to be guaranteed as well as their data’s security. This thesis addresses the problem of data anonymity in BlobSeer, a large-scale distributed storage system. The easiest way to hide data from other users is by encrypting the data we want to store. We could additionally split the data and make from it a padding inside the BLOB we are using. The step of splitting the data and scattering the pieces inside a blob is very useful because an attacker will not be able to find where the data is written as its location is encrypted as well as the data itself. In this way the data we want to store via a BLOB will be hard to be tracked down and decrypted by other users.
