- W2350650050 abstract "The technique of reversible watermarking can strictly recover the original cover data,with the watermark accurately extracted at the same time.Therefore it is more suitable for digital copyright protection of vector maps.A new space feature-based reversible watermarking for 2D-vector maps is proposed.Under the condition of keeping relative locations of feature points,this algorithm nonlinearly scrambles the location of feature points according to the predefined secret key to avoid unauthorized users using high-accuracy vector data.Then it embeds watermark into the scrambled feature points and can recover the original 2D-vector maps with the watermark extracted at the same time.The experimental results show that the proposed watermarking method is strictly reversible with preferable invisibility." @default.
