Securing multimedia content through encrypton and decryption - Final Year Project Report (CSC-404) 

Abstract

Multimedia data security is becoming important with the continuous increase of
digital communications on internet. The wide use of audios and videos in various
applications brings serious attention to security and privacy issues today.
With the continuing development of both computer and Internet technology,
multimedia data (images, videos, audios, etc.) is being used more and more widely. In
order to maintain privacy or security, sensitive data needs to be protected before
transmission or distribution. This project made research on different encryption
algorithm and how they can be implemented through programming language. So, in
this research based project, Rijndael algorithm is studied and application is developed
based on it which helps to protect the multimedia content by encrypting multimedia
data.
Rijndael is collection of block ciphers used for cryptography applications, and three
of the Rijndael block ciphers (also referred to as Rijndael algorithms) were adopted as
algorithms for use in Advanced Encryption Standard (AES), which is a symmetric-
key encryption standard that was ratified by the National Institute of Standards and
Technology (NIST) as United States (U.S.) Federal Information Processing Standard
PUB 197 (FIPS 197) on Nov. 26, 2001, and adopted by the U.S. government as a
Federal government standard on May 26, 2002
This project attempt to make and web based application in ASP.NET which can be
used by any users. This project demonstrates how a simple audio and video
encryption application can be created easily using ASP.NET. This application
provides basic functions that an encryption application must perform.
