Watermarking, which belongs to the data hiding field has seen plenty of research interest recently.

Handbook of Visual Display Technology pp Cite as. Securely embedding data in digital images has important applications for covert communication and copywrite protection. The specific algorithm used to embed information depends on the characteristics of the application. Two prominent techniques for embedding information are least-significant-bit modification, and discrete-cosine-transform modification. Detecting modifications to a high bit-rate signal such as a digital image can be difficult, and is the subject of cross-disciplinary research in statistics and signal processing.

A digital watermark is a kind of marker covertly embedded in a noise-tolerant signal such as audio, video or image data. It is typically used to identify ownership of the copyright of such signal. Digital watermarks may be used to verify the authenticity or integrity of the carrier signal or to show the identity of its owners. It is prominently used for tracing copyright infringements and for banknote authentication. Like traditional physical watermarks , digital watermarks are often only perceptible under certain conditions, e. A signal may carry several different watermarks at the same time.

Information Security Stack Exchange is a question and answer site for information security professionals. It only takes a minute to sign up. I have a PDF file that I want to embed an invisible and fragile digital watermark. What are the suitable algorithms available for this task? This is not, strictly speaking, a watermark -- but it is invisible and fragile, as requested.


Steganography and steganalysis (the art of detecting hidden information) have been added to a robust treatment of digital watermarking, as many in each field.

A study of influence between digital watermarking and steganography Abstract: Researches about steganography and watermark mostly focus on either field separately. However, their correlation is ignored while they apply highly similar techniques to hide information in images. Watermark is commonly added in some websites after an image is uploaded.

Lecture notes for undergraduate and first-year graduate students on digital watermarking and data embedding in multimedia data. Steganography is the art and science of hiding data within innocent-looking objects cover objects. Multimedia objects such as images and videos are an attractive type of cover objects due to their high embedding rates. There exist many techniques for performing steganography in both the literature and the practical world. Meanwhile, the definition of the steganographic capacity for multimedia and how to be calculated has not taken full attention. Audio steganography is a technology that embeds messages into audio without raising any suspicion from hearing it.
