Digital Watermarking for Image Authentication
Digital Watermarking is a technology used to authenticate and protect digital images. It embeds a hidden code or signature into the image which can be used to identify the original owner of the image. This technology has become an important tool in protecting intellectual property rights, as it allows copyright holders to track and enforce their rights. Digital Watermarking also provides a layer of security against unauthorized use, as it is difficult for someone to remove the watermark without damaging the image itself. By using Digital Watermarking, companies can ensure that their images are protected from unauthorized use and that they are able to receive credit for their work.
