It is a risk to transmit information in the Internet. How to protect the security of information transmission is becoming popular research topic in recent years. This thesis presents a new information hiding technique using TS (tabu search) and OLSB (optimal least significant bit) substitution named TS-OLSB. An optimal LSB substitution may enhance the quality of stego-image. In addition, a Tabu search can obtain near optimal solution. Therefore, this paper hybridizes Tabu search and optimal LSB substitution for image hiding processing. According to the simulation results, it is observed that the proposed method outperforms optimal LSB substitution and genetic algorithm hybridizes OLSB (GA-OLSB) in time cost and peak-signal-noise-ratio (PSNR) comparisons. This thesis presents another new information hiding technique using improved LSB matching, two-sided side match (TSM) steganography and optimal substitution named ITSM (Improved TSM). This technique divides into two parts. First, using improved LSB matching method may enhance the capacity of stego-image. Second, hybridizing TSM and optimal substitution named optimal TSM that may maintain the quality of stego-image is used. Therefore, this thesis hybridizes improved LSB matching and optimal TSM for image hiding processing. According to the simulation results, it is observed that the proposed method outperforms TSM in capacity and peak-signal-noise-ratio (PSNR) comparisons.

With the progress of development in computer and networking technologies, digital text documents nowadays have become much more popular than in the past. The XPS (XML Paper Specification) document is a new text file format which is portable to any computer to produce identical page layouts with high printing and browsing qualities. In this study, three data hiding methods utilizing certain properties of the XPS are proposed for covert communication, text authentication, and steganography. For covert communication, the proposed data hiding method uses a single cover image in an XPS document as a data embedding channel. A secret message to hide is encoded as certain rectangular-shaped patterns according to a table designed in this study, and the patterns are described by Path elements in XPS files for use in dividing an image hierarchically in the XPS document. The divided image pieces then are composed together seamlessly to form the original image, thus accomplishing imperceptible data embedding in the document. Furthermore, since XPS documents are widely used on the Internet, malicious users may try to intercept and tamper with their contents. This requires XPS document authentication for which a novel method is proposed in this study. Specifically, the digests of the texts in an XPS document to be protected, after being encoded by specific gradient patterns, are used as authentication signals. To verify the integrity and fidelity of the text content of a suspicious XPS document, the authentication signals extracted from it are compared with those computed from its current text segments for decision making. Finally, keeping secrets in XPS documents without arousing notice from possible attackers is necessary in many information security fields. For this kind of steganographic application, a method inserting specific invisible and width-adjustable ASCII codes between words in the texts of XPS files for encoding secret messages is proposed. The resulting stego-document appears to be identical to the cover document with no width increasing between the text words. Measures to enhance the security of each proposed method are also suggested. Good experimental results show the feasibility of the proposed methods.

iii created from a grayscale image of a secret document, yielding a steganographic effect of hiding the secret document into the mosaic image, though visibly. The selection of the most similar target image from a database is based on a newly-proposed k-feature of the grayscale value, which speeds up the image creation process. Finally, for secret sharing, a secret image is shared to yield multiple secret-fragment-visible mosaic images. In order to disperse tile images evenly in selected target images, the target images take turns randomly to pick appropriate tile images. In addition, various security enhancement measures were proposed to make the embedded data more random to prevent hackers’ attacks. Experimental results show the feasibility of the proposed methods for image creation and data hiding applications. In this study, a new type of art image is created, which is called secret-fragment-visible mosaic image. And this kind of new mosaic image is used for three applications of data hiding, namely, covert communication, steganography, and secret sharing. First, the newly-proposed secret-fragment-visible mosaic image is created to be composed of rectangular-shaped fragments which come from division of a secret image. A new 1-D h-colorscale is proposed to represent the color distribution of an image based on the color feeling of human vision. To create a secret-fragment-visible mosaic image, a new image similarity measure based on the h-colorscale is proposed, and the most similar candidate image from an image database is selected accordingly as a target image. Then, a greedy algorithm is adopted to fit every tile image in the secret image into an appropriate block in the target image. Furthermore, to solve the problem of using an insufficiently-large database, a remedy method by enlarging the size of a target image is also proposed. Secondly, for covert communication, based on the fact that tile images which are in an identical histogram bin have similar colors, the tile images in an identical histogram bin are reordered, or equivalently, the relative positions of the tile images are switched, to embed secret message bits imperceptibly. Third, for image steganography, a grayscale secret-fragment-visible mosaic image is

A new type of art image is created in this study, namely, tetromino-based mosaic image. Methods for automatic creation of images of this type and data hiding in them are proposed. For the creation of tetromino-based mosaic images, we find all the possible combinations of tetrominoes by a tree enumeration algorithm. A tetromino database is constructed with different colors and tetromino combinations for image creation. We also propose a border enhancement process for improving visual effects of tetromino edges. For data hiding in tetromino-based mosaic images, we utilize two types of features of mosaic images, tetromino combination and color, to embed data. We can hide data by using distinct combinations of tetrominoes. An edge fitting method is used to enhance edge effects by adjusting combinations of tetrominoes using the information obtained by edge detection. In addition, the colors of tetrominoes are also used to hide data by shifting color values of tetrominoes slightly. For watermarking in tetromino-based mosaic images, we propose a removable lossless watermarking method by replacing the colors according to a mapping between two color palettes. Based on this invertible watermarking method, an image steganographic method is also proposed by replacing the colors of the watermark area according to the proposed mapping between the two color palettes. Experimental results show the feasibility of the proposed methods and systems.

Because of the proliferation of digital images on the Internet, people can carry and transmit information by digital images conveniently. For this purpose, some methods for covert communication are proposed in this study. Besides, with the advances of digital techniques, digital images may be copied or tampered with illegally. To solve such problems, some methods for copyright protection and tampering detection for various types of images are proposed in this study. For grayscale images, a method based on visible watermarking techniques and a human visual model is proposed to protect copyrights and detect image alterations. For binary images, a data hiding method is proposed to embed up to two bits in a 3´3 image block by changing at most just one bit in a block. An authentication method for verifying the fidelity and integrity of binary images is also proposed, which creates authentication signals by rearranging the pixels in image blocks. Three methods integrating various data hiding techniques to embed invisible watermarks, visible watermarks, annotations, and authentication signals into three types of images are finally proposed. Good experimental results prove the feasibility of the proposed methods. Finally, some mechanisms for multiple authorizations of images are proposed and some functions of an image authentication center are also suggested.

With the advance of hardware and software technologies, digital information can be easily created, seamlessly manipulated, and widely distributed. Therefore, information security has become one of the most critical and challenging problems in recent years. This dissertation is dedicated to solving the problems of protection and secure transmission of digital information. One way to protect various types of digital information is to hide them in images. In this approach, reduction of embedding distortion is one of the major concerns. To design imperceptible data hiding methods, three techniques for distortion reduction are proposed in this study. First, the first technique is based on the new concept of embeddability proposed in this study, which is defined as a measure for checking the quality of stego-images yielded from embedding secret data in cover images. Only embeddable pixels are used to embed data. The other two techniques are proposed for minimizing embedding distortion from a global view. One is based on the use of error-correcting coding to create correctable errors corresponding to the data to be hidden, with the effect of minimizing embedding distortion. These errors can be detected, corrected, and so extracted to recover the hidden data. The other technique is based on providing multiple code holders as candidates for embedding data. An optimal code holder which results in the least embedding distortion is selected to embed data. On the other hand, also proposed are five new techniques for data embedding and four new techniques for solving various digital information hiding and authentication application problems have been developed. More specifically, two methods of data hiding in binary and palette images, and two methods of authentication of binary and palette images are proposed. In the proposed data hiding methods, not only can general digital information be embedded into binary and palette images without introducing noticeable distortion, but also can the credibility of the hidden information be verified. Besides, some tradeoffs between design requirements, including that between image quality and embedding capacity as well as that between the accuracy of authentication and the portability of authentication information, are addressed and solutions for balancing these requirements are proposed. Furthermore, a new method for embedding binary images into cover noise images is proposed. It is argued that there is no need to find a meaningful cover image for data hiding. Instead, a cover noise image which has larger embedding capacity can be used to hide a secret binary image. Nevertheless, a general approach to data hiding based on the employment of error-correcting coding is also proposed. Both embedding of digital information into images and authentication of the results are achieved by the error-correcting as well as error-detection abilities of an error-correcting scheme. On the other hand, a novel content-based authentication method based on the use of digital signatures is proposed. The concept is to extract visual color and edge features, which are invariant to content-preserving manipulations, from image blocks, as digital signatures. The authenticity of each image block can be verified by comparing its features with the corresponding ones recorded in the digital signature. The performances of all the above proposed methods have been evaluated extensively by theoretical analyses and experiments. The results indicate that they are feasible for practical applications.
