Partial Image Encryption using RC4 Stream Cipher Approach and Embedded in an Image

Abstract

Cryptography is a science concerned with securing data transmission. By applying cryptographic operations to data, readable information is converted into unreadable data. Currently, security is of great importance. Data transferred over the internet must have some form of encryption. Different forms of multimedia contents are moved over the internet. This paper focuses on image encryption. It tries to amend the multiple selective region image cryptography techniques using a RC4 stream cipher. This approach is derived from the standard RC4 algorithm. The proposed method can highly improve security for images transferred over the internet.
