摘要: Authenticating in transaction of digital media becomes an active research field now a day. That is emerging due to the illegal use and hacking by unauthorized users. Spatial domain based watermarking methods are one authentication methods. These not generally robust against intentional or unintentional changes images. In this paper, new method proposed recover watermark more precisely spatial method. A high-boost filtering utilized before executing extraction procedure. The information magnified preforming filter. Effectiveness filter proved several experiment. Experimental results show that performance correlation algorithm improved recovery
