Security Features on and with Documents: A Survey

In today’s world, Security for any means has become really important. That stands for either hard copy or the soft copy of any document. The concept of online transactions or simply digital transactions has become a rage over a period. To accommodate such stuffs, there arises a need of transforming hard copies of document into soft copy ones. This would further lead to the crisis where there is a need to provide security for these soft copies. The documents when maintained as soft copies are vulnerable to all sorts of attacks either through bugs and/or through human errors. These human errors are the ones that need to be taken care of in a large scale. Some people believe in sharing documents through online with their peers or others of same interest. This may lead to the misuse of these documents when they fall into wrong hands. Then, the security of these documents becomes a topic to dwell on. In this paper, a study was conducted based on the ways to secure data and the techniques or algorithms that can be used to do it. There are many different technologies based on the type of data that is being encrypted. These are being discussed along with the papers that were taken into account for various data Security methods.
