Abstract:
Due to advances in technologies, most of the
information is kept electronically.
Steganography and Cryptography are two
popular ways of sending vital information in a
secret way. In this paper, an image
steganography technique is proposed by
combining cryptography and steganography. The
proposed technique uses LSB-based data
embedding technique and RC4-liked keyed state
vector to hide the encrypted message. Before
embedding the secret message, RC4 encryption
algorithm is also used for message encryption.
After encrypting, the encrypted messages can be
embedded according to state vector size. The
secret messages can be randomly hidden in BMP
image file by using LSB technique. This system
can protect the privacy of information.
Moreover, this technique supports for data
integrity and data confidentiality.
