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 techniques or information hiding are concerned with hiding the existence of data in other cover media. Usually one hiding method is used to hide secret data in a cover text and that will reduce the security, so in this paper we will use more than one hiding method to hide secret data according to syntax grammars of cover text produced by a special parser.
We represent the Arabic language grammar as logical terms and use B+tree for storing, and Augmented Transition Network) ATN) for parsing.
The proposed technique was implemented using Visual Prolog and after testing according to the authorized measures that are used in this field The proposed approach has provide good security (transparency) for steganography.

The growth of information technology and data transfer led to increase the data
attacks, so that information security becomes an important issue to keep the data
saved during information exchanges in computer networks. Steganography
techniques used to protect the information from being detected. The art of
steganography will hide secret information into cover data, which will be sending
without any change so the attack does not recognize any change into cover image.
This paper use the Steganography and artificial neural networks to presents an
information hiding procedure for hiding text in cover image, the secret text will be
converted to binary code, also the cover image will be converted to the binary data
in form of vectors. The supervised learning of neural networks will use binary
patterns of hidden text as set of input values, and the corresponding cover image
data as target that used as teacher signal to neural network. The generated weights
from neural network and the coordinate of data block of cover image have been
saved and then used to extract hidden text data.

Using B+ Tree To Represent Secret Messages For Steganography Purpose

Engineering and Technology Journal, 2010, Volume 28, Issue 15, Pages 5102-5112

In this research we suggest a new approach by using B+ tree for storing the secret massages (that want to be sent) in a manner that prevent redundancy of these massages or even sub massages in order to provide efficient memory usage . The proposed system includes two stages: Stores the secret message and get its unique code by using B+ tree, and retrieves the unique secret message when we have its code by using B+ tree. The proposed system was implemented using Visual Prolog
5.1 and after testing, the proposed system gives an efficient time in storing and in retrieving the secret messages, also the proposed method solved the ambiguity problem that some steganography methods suffer from.

Information hiding is a means to conical and transmitting information using
apparently innocent carrier without depiction any suspicions. This paper presents a
new means for information hiding based images by using Hybrid of Parametric
Spline and DFT. A set of control points, which represents secret key, are selects
randomly from the carrier , and a curve pass by the selected control points is
implement using B-Spline. A hiding process for the secret message bits tacks
place on the spectral real part of the intensity pixels where the B-Spline curve
passes by using LSB technique, followed by the IDFT. The paper also presents the
information hiding features, and techniques for images, and Interpolation
techniques. The Objective fidelity criteria are depicts the improvements in
algorithm with an application example.
