        abstract = {Image processing technology has been developed rapidly in recent years, and altering the content of an image is easy for everyone, but may be illegal for an attacker. Thus, it is urgent and necessary to overcome this problem to protect the integrity and authenticity of images. Watermarking is a powerful technique proposed to solve this problem. So dealing with these Real world problems in the recent years have become more complex, hence more powerful optimization techniques are needed to solve these complex and unsolvable problems. Digital watermarking is an effective approach, which handles watermarking problem by encoding use or other copyright information directly in the data without providing any access restrictions to such data. In this paper a new scheme is developed for an efficient robust watermarking technique using Bees algorithm & area of best fit equation. The watermarks are embedded into the HL and LH frequency coefficient in wavelet transform domain. Science, the embedding technique is blind which does not require the original image is the watermark extraction. As well the scheme also searches the optimal location in order to improve both quality of watermarked image & robustness of the watermark. The performance of the proposed watermarking technique is watermarking technique is analyzed in terms of Peak signal-to-noise ratio (PSNR) and Normalized Correlation (NC).},
