Abstract:
Steganography is the method of
communicating secrete information hidden in the
cover object, that may be text, image, audio,
video, and protocol for the purpose of hidden the
existence of secret messages. In this proposed
system, cover object is image because it is the
most popular carrier on the Internet. In this
system, it has contain four parts: first, the input
message is resized using message conversion
algorithm, in second, the message is compressed
based on the index-based compression algorithm,
in third, the compress message is encrypted by
using random-based transposition cipher for
message encryption and finally, the cipher text
message is hidden in blue channel of LSB of cover
image. This system provides sufficient complexity
and only key are required for embedding process,
but not for encryption.
