“…To embed the parameters needed in the stego-texture decoding process, we used an RSA algorithm [27] to encrypt the parameters and extended the FPcode [26] to embed the ciphertext. The FPcode uses the relative average intensity of adjacent blocks in the cover image to embed a bit string; therefore, it is less sensitive to changes in illumination conditions and the degradation caused by printing.…”

We present stego-texture, a unique texture synthesis method that allows users to deliver personalized messages with beautiful, decorative textures. Our approach was inspired by the success of recent work generating marbling textures using mathematical functions. We were able to transform an input image or a text message into an intricate texture by combining the seven basic, reversible functions provided in the system. Later, the input image or message could be recovered by reversing the process of these functions. During the design process, the parameters of operations were automatically recorded, encrypted and invisibly embedded into the final pattern to create a stego-texture. In this way, the receiver could extract the hidden message from the stego-texture without the need for extra information from the sender. To ensure that the delivered message is unnoticeably covered by the texture, we propose a new technique for automatically creating a background that is harmonious with the message based on a set of visual perception cues.

“…To embed the encoded bit string into a texture, we adopted the FPcode proposed by Genta et al [26] because it has a relatively large embedding capacity and is robust against color distortion caused by scanning, printing or the illumination To embed a bit string, the original texture (Fig. 11) is divided into row × col blocks.…”

“…Then the parameters of marbling operations are encoded into an encrypted bit string and embedded into the marbling pattern to create a stego-marbling-texture using a steganography technique. We use RSA algorithm [11] to encrypt the parameters and extended FPcode [12] for embedding the marbling parameters. Typical steganography algorithms, such as those based on LSB [9] [10], usually cannot resist from the image degradation caused by printing or capturing.…”

We present stego-marbling-texture, a new and unique texture design method which allows users to deliver personalized messages with beautiful marbling textures. Our approach is inspired by the success of the recent work on modeling traditional marbling operations as mathematical functions. The encrypter transforms an input image or a text message into an intricate marbling pattern using marbling operations defined as reversible functions, and the decrypter recovers the input image or message through reversing the process of marbling operations. When applying marbling operations, the parameters of operations are automatically recorded, encrypted, and then invisibly embedded into the marbling pattern to create a stego-marbling-texture. In this way, the decrypter can be implemented as a stand along software, enabling the receiver to extract the hidden message from the stego-marbling-texture without requiring any extra information from the sender. To ensure that the message is unnoticeably and beautifully covered by the marbling texture, we propose a new technique for automatically creating a background which is harmonious with the input message based on a set of visual perception cues.

“…Although those enhanced codes are visually more pleasing than the original QR code, they all suffer from the lacking of design flexibility, since they are basically 2D bar codes. FPcode [10] and CLIC2C [1] uses water marking technology to embed information into images. However, these techniques embed information by altering the intensity or color of original images and hence are not suitable for many logo images, which are abstract symbols with no locally change of color or intensity.…”

2D image codes are widely used for inputting information to mobile devices with cameras. QR code is a typical example of such codes. Conventional image codes do not have semantics in images themselves. Such codes may spoil the quality of design when attached on commercial products. We propose a novel code, Be-code, for embedding data into logo images. Be-code is generated from a logo image by modifying some of the edge pixels according to the bits to be embedded, but avoiding causing obvious change to the appearance of the original logo image. Algorithm for extracting information from the camera captured Be-code is also presented. The original logo image is not required in decoding. In experiments, embedded data could be decoded at a high success rate.
