Digital Image Watermarking using LSB Technique
Watermarking belongs to hide particular information, so that you can easily detect any tamper detection .It is used for confidenality, authentication and copy right protection. In this paper watermarking is done with the help of least significant bit technique (LSB).As LSB technique is used as it has less effect on image. This new algorithm is using LSB of original image and idoing ‘&&’ operati...
متن کاملImage 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 کاملDigital Watermarking Method Using Replacement of Second Least Significant Bit (LSB) with Inverse of LSB
In this paper new algorithm proposed for digital watermarking using Least Significant Bit (LSB) .LSB already used but there is a slightly effect on the image. The above algorithm is using LSB & second LSB bit. Here we used binary value of watermark text in LSB, and in place of second LSB, the inverse of their correspond LSB bit. The proposed algorithm is flexible depending on the length of wate...
متن کاملA Watermarking of Medical Image: Method Based "LSB"
In this paper, we present a new approach for watermarking of medical image that we are trying to adapt to telemedicine. This approach is intended to insert a set of data in a medical image. These data should be imperceptible and robust to various attacks. It’s containing the signature of the original image, the data specific to the patient and his diagnostic. The purpose of the watermarking met...
متن کاملPerformance Evaluation of LSB Technique for Digital Watermarking
Watermarking of digital content is an imperative and interactive method for identification and protection of digital data. It allows veritable watermarks to be hidden in digital data for example image, audio, and video. Procedure of embedding and extracting of watermark from original image and watermarked image is complex. These include randomization of the watermark and selection of locations ...
