With the increasing use of internet and major development in technology, transmission of digital media is being affected by a large number of illegal interventions.As a valuable solution to this, watermarking provides a secure way for channelizing the digital media (image, audio or video).Digital Watermarking is a method of embedding data (watermark) into a host image without degrading its original quality.This paper presents Digital Image Watermarking in Spatial Domain by finding the Mean and Variance of host image and using the well-known method of Least Significant Bit (LSB) to embed the watermark in a secure position.The experimental results analyze the strength of proposed watermarking algorithm against attacks like Salt and Pepper noise and Gaussian noise.
