Abstract:
In the current computing community, secure
data transfer is limited due to its attack made on
data communication. Solutions which came to the
rescue are cryptography and steganography.
Cryptography is often used in situations where the
existence of the message is clear, but the meaning
of the message is obscured. In particular, the
sender transforms the message into a form that
only the intended recipient of the message can
decrypt and read. Steganography is often used in
situations where the actual existence of the
message needs to be obscured. This paper is
intended to ensure secure data transfer between the
source and destination by providing double layer of
protection using both cryptography and
steganography. To implements both cryptography
and steganography, the message was encrypted
before it is hidden inside a cover image. In this
paper, the encryption was done by using vigenere
encryption method and the ciphered message was
embedded by using LSB algorithm.
