Image security is playing a key role in present real-world situations as the data transferring is mainly through digital images which may not secure. Hence, we present a novel algorithm for image watermarking using the error recovery adder and discrete wavelet transform. This process involves the hiding of one secret image into the host image qualitatively. For this process error recovery adder (ERA) is used to select the dynamic threshold value from the minimum values of the secret and host image. This error recovery adder reduces delay of the process. This work consists of both embedding and extraction process. The experimental consequences propose that the projected method provide results with high PSNR values.
