Steganographic Watermarking for Documents
نویسندگان
چکیده
The present paper defines Digital Seals for Documents, their scope, application environment and limitations. These seals can be used to insert information on documents, as with watermarking, or to use documents as a communication channel for sending concealed messages, as it is the goal of steganography. Users can decide to employ one, another functionality, or a combination of them depending on their needs or

Proposing an effective approach for Network security and multimedia documents classically using encryption and watermarking
Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...
متن کاملDevelopments in Steganography
This paper presents two main results. The first is a new approach to steganography in which data is encoded in correlations among the pixels in an image. Almost all previous steganographic methods encode data in correlations between the pixels and a known external reference signal. This method hints at the existence of public key watermarking techniques, which will be defined. The other result ...
متن کاملTexture based steganalysis: results for color images
Steganographic and watermarking information inserted into a color image file, regardless of embedding algorithm, causes disturbances in the relationships between neighboring pixels. A method for steganalysis utilizing the local binary pattern (LBP) texture operator to examine the pixel texture patterns within neighborhoods across the color planes is presented. Providing the outputs of this simp...
متن کاملMeasures for classification and detection in steganalysis
Still and multi-media images are subject to transformations for compression, steganographic embedding and digital watermarking. We propose new measures and techniques for detection and analysis of steganographic embedded content. We show that both statistical and pattern classification techniques using our proposed measures provide reasonable discrimination schemes for detecting embeddings of d...
