2. LITERATURE SURVEY
Before discussing in details of literature survey, lets us define some of the basic terms used.
In short Encryption is the process of translating plain text data (plaintext) into
something that appears to be random and meaningless (ciphertext). Decryption is the process
of converting ciphertext back to plaintext.
As the data is stored in public cloud, .i.e. the data if as it is placed is not too safe. To protect
the data stored in cloud so encryption most be used so that the data is kept as cipher text
instead of plan text.
But for the condition checking of deduplication data already stored most be check,
but the data is in cipher text with some user key with will be unknown for the checking of
data for duplication purpose. So this traditional encryption method is not able to detect the
duplication in cloud storage as shown in Figure 2.1
