“…The SM can be easily converted to binary to produce a message binary matrix, the 8_bits binary representation is to be used and MBM will contain 8 columns and number of rows equal the number of characters in the SM. MBM can be easily reshaped to 1 or more columns and vice versa, figure 1 show various methods of SM representation [55][56][57][58][59]. In this research paper SMs will be classified to short messages (with length up to 100 characters), medium messages (with length less or equal 1000 characters) and long messages (with length greater than 1000 characters) [49][50][51][52][53][54].…”

High quality of the stego media is an important issue to evaluate the stego system, the stego media must be closed to the covering one and the MSE measured between them must be low as possible, while the PSNR measured between them must be high as possible. In this paper research a detailed analysis of stego media will be produced, the quality of digital color image will be compared with the quality of digital speech file. Digital color image will be used to hold various messages, the same messages will be hidden in a digital speech file, and the quality parameters will be calculated. The results of using the image will be compared with the results of using digital speech file to raise some recommendation. 2 and 4 bits for message hiding will be tested using short, medium and long messages.

“…Methods of protecting information varied between encryption and steganography. Encryption is the conversion of confidential data into an unreadable format [1] which is a sprinkling of letters that do not give any meaning only those who possess the encryption keys can decipher the text and return it to an understandable format [2].…”

“…Information hiding is the technique of protecting information from direct change or tampering with its content by unauthorized parties and delivering the information confidentially and securely to the requested party. The field of information hiding is considered important and vital due to its many applications in protecting copyrights, protecting personal information, credit cards, and exchanging confidential information [2].…”

Protecting information from manipulation and theft is a top priority as a result of progress in technology and the infrastructure of the multimedia network in addition to the development of illegal methods of obtaining information. One of the means of protecting and preserving information is to hide it in a digital medium. The motivation for introducing such a system is to enhance the security of confidential data by providing ways to protect the data and reduce attempts to attack it. The proposed system contains several steps summarized as follows: The sender side includes firstly the stage of generating hiding locations randomly depending on the genetic algorithm (GA) to generate rows and seed to generate columns. Secondly, the stage of including data after compressing it by the Huffman method. Data embedding depends on the pixel index as an indicator to choose one of the three bands to hide using LSB. The recipient side extracts the important information hiding in the two last rows which helps to extract the data and convert it into the original text. The proposed system gained efficiency and robustness with the help of genetic and Huffman where genetic chooses the best way for hidding among a set of suggested solution in addition to the randomness it possesses. The role of Huffman reduce data size and thus increase the cover capacity. System efficiency has been measured by PSNR through conducting a number of experiments that included using set of texts with different sizes and two types of standard colored cover images.

“…The proposed of this research paper is to introduce a new method of DCI hiding-extracting, which will provide the following enhancement [41][42][43][44][45][46][47][48][49][50]: -Making the hiding capacity unlimited, by resizing the covering image, the size of the DCI to be hidden may be greater than the size of the covering image [51][52][53][54][55]. -Covering image may have any size and any type (gray image or color image).…”

A simple and secure method of digital color image steganography method will be introduced, the method will hide a digital color image in another image, the covering image will be any type and with any size (the covering image can be smaller than the image to be hidden, thus the capacity of the covering image will be unlimited. The proposed method will apply image resizing, the resizing factors will form the private key to protect the hidden image from being hacked, this key will provide a good key space to secure the image, the extracted image will be very sensitive to the selected values of the private key components. A simple way of image bits hiding and extracting operation will be used, the image bit matrix will converted to one column matrix and embedded in the LSBs of the covering bytes using one assignment operation, the LSBs of the stego bytes will extracted using one operation to create a one column matrix, which will be converted to 8 columns matrix to form the image binary matrix. The method will be implemented and tested using various covering images and various color images to be hidden. The obtained results will be analyzed to prove the quality, speed and sensitivity of the proposed method.
