摘要：The major concern while using internet is the security of the transmitted and the stored data. The proposed system will provide a solution to the security and the problems of the centralized database system. To achieve this task, the concept of distributed database and cipher text will be used. In distributed database portions of the database are stored on multiple computers within a network. Users have access to the portion of the database at their location so that they can access the data relevant to their tasks without interfering with the work of others. Cipher text is encrypted text i.e. the original text is converted into unreadable text using some algorithms so that unauthorized user could not get access to the information. Most systems are based on the concept of centralized single database. The centralized database acts as the backbone of the whole system. If the centralized database gets failed, whole of the system crashes. Moreover the data stored in the database is stored as plain text. If anybody gets access to the centralized database, the information could be easily retrieved. Secured transmission of data is a wide area of research in networking as data is the most crucial element of any organization also the risk of getting the information leaked or hacked these days has also increased. The Paper is divided into five Section which include introduction in the first section , review of literature with several attacks explanation in second section, third section explain some countermeasures to overcome different problems. Finally, we end up our paper with a conclusion and future scope.
