Abstract
Copyright to an image is very important so that it is not misused by irresponsible parties, many ways can be done to provide copyright information in an image. Watermarking is a technique commonly used to mark a picture that the image already has copyright and whose owner is known, but in addition to visible watermarking there is also an invisible watermarking to indicate an image on a pixel or also in byte code and this is invisible. The Patchwork Algorithm is an algorithm that can be used to give an image to the image as an authenticity image so that many parties cannot claim it and are quite good from various modifications of image, application that has been created are purpose to embedded information as invisible watermarking in the image.
Highlights
Information can be something that is very valuable and must be kept confidential [1]–[7]
Another method that has a way of working with steganography is the watermarking method which is generally used as an identifier of digital media such as images, audio or video[16]–[20]
Patchwork technique uses redundant pattern encoding and spread spectrum methods to hide information into the entire cover image, in using redundant pattern encoding the message or information that you want to secure on a cover can only be done once because it will occupy a large enough position from the picture[21]–[24]
Summary
Information can be something that is very valuable and must be kept confidential [1]–[7]. Steganography is a science and art that studies the concealment of confidential data in a media in such a way that its existence is not detected by other parties who are not entitled to the information[13]–[15]. Another method that has a way of working with steganography is the watermarking method which is generally used as an identifier (digital signature) of digital media such as images, audio or video[16]–[20]. Watermarking is a form of steganography in learning the techniques of storing data (digital) into other digital host data. Patchwork technique uses redundant pattern encoding and spread spectrum methods to hide information into the entire cover image, in using redundant pattern encoding the message or information that you want to secure on a cover can only be done once because it will occupy a large enough position from the picture[21]–[24]
