Internet has revolutionized the way people share information, store
data, communicate, learn, and do business. Internet has been used for
information transmission; this has changed in the last decade. Today,
governments, businesses and individuals are increasingly relying on-line
applications; the need to secure data exchange over the Internet and
store it on the cloud has gained more importance. Data security aims to
keep information safe by using cryptography and/or steganography.
Steganography is a suitable candidate for keeping information safe,
hiding the existence of data itself inside another medium. The Least
Significant Bit (LSB) algorithm is one of the most common techniques to
hide secret messages in an image. The main problem with LSB is knowing
whether such an image has a secret message inside, making it easy to
retrieve it by collecting the least significant bit from the steg-image.
This paper presents an attempt to improve the security level of the LSB
algorithm by using a secret steganography key. The proposed algorithm
SKLSB is encoding the secret key from the cover image, encodes the
secret message using the secret key, embedding it to the cover image.
Even if attackers know about the steganography, they cannot know about
the secret key. The SKLSB algorithm helps to get a higher and better
level of security, useful for keeping sensitive, relevant, and important
information stored. The results regarding this paper are compared with
LSB algorithm regarding its Mean Square Error (MSE) and Peak Signal to
Noise Ratio (PSNR) values aiming to show this method is more secure and
does not affect the image imperceptibility.
