Image Watermarking Using LSB (Least Significant Bit)
With the rapid development and wide use of Internet, information transmission faces a big challenge of security. People need a safe and secured way to transmit information. Digital watermarking is a technique of data hiding, which provide security of data. This paper presents a watermarking technique which least significant bits (LSB), its steps and its process with matlab images.
متن کاملA New Digital Watermarking Algorithm Using Combination of Least Significant Bit (LSB) and Inverse Bit
In this paper, we introduce a new digital watermarking algorithm using least significant bit (LSB). LSB is used because of its little effect on the image. This new algorithm is using LSB by inversing the binary values of the watermark text and shifting the watermark according to the odd or even number of pixel coordinates of image before embedding the watermark. The proposed algorithm is flexib...
متن کاملModified Least Significant Bit (MLSB)
Steganography is the science of writing hidden messages is such a way that no one except sender and intended recipient can realize there is a hidden message. Compared with cryptography we can say that, steganography’s in security work as supplement to cryptography, not replace it. So to add another layer of protection we can encrypt the hidden message (Johnson & Jajodia, 1998). A survey of curr...
