Image steganography is the art of hiding data into an image by using the secret key. This paper presents two techniques that combine the most significant bit (MSB) as well as the least significant bit (LSB) based on a color image (24bit for RGB). The presented study proposes a novel method to combine (LSB and MSB) bits based on check MSB values and replace bits from LSB with a secret message. The result of this proposed method that made not affect quality stego -image based on the resulting histogram that shows a match between the cover image and stego- image and more secure because not hidden in all image. The factors were used Mean Square Error (MSE), Compute Payload, in addition to Peak Signal to Noise Ratio (PSNR). The PSNR’s rate is high and MSE is less. The result of this paper when applying on the different image gives high PSNR of 87.141 and less MSE of 0.00012 when inserting message 80 bits and reduction value PSNR of 72.023 and MSE of 0.0040 when inserting message 1200 bits and measure entropy is the same value for cover image and stego –image then this method is more security for the attacker.

Steganography is the art of hiding, and transmitting information using
apparently innocent carrier without expose any suspicion. This paper present a
natural language steganography technique, which is different from all the natural
language steganography technique, that uses structure of the sentence constituents
in natural language text in order to insert a secret hidden information, or all others
techniques, which hide information by modifying the appearance of text elements,
such as lines, words, or characters. The proposal technique use the secret hidden
text information to generated the stego-cover carrier text by using algorithms
depend on natural language processing, particularly text generation field. A survey
for natural language terminology, techniques, and tools for text processing, a
natural language steganography technique and its difficulties to implement
methods like LSB's is presented. The results shows that, the proposal technique is,
a successful one in implementing methods like, LSB's for natural language bit
steganography .
