Security Features on and with Documents: A Survey

Abstract In today’s world, document security has become essential. That stands for either a hard copy or a soft copy of any document. The concept of online, or digital, transactions has become increasingly prevalent in recent years. To accommodate these transactions, there arises a need to transform hard copies of documents into soft copies. This would further lead to a 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 human errors. These human errors are the ones that need to be taken care of on a large scale. Some people believe in sharing documents online with their peers or others of the same interest. This may lead to the misuse of these documents when they fall into the 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.
