Paper Abstract

With the rapid development of earth observation missions and internet technology, there is increasing recognition that internet is an effective channel for disseminating digital remotely sensed data. To cope with the security problems accompanying with internet-based remote sensing, a multipurpose watermarking technique of remote sensing images is proposed in this paper for copyright protection and authentication in the spatial domain and the wavelet domain. The proposed scheme can utilize the human visual system (HVS) to embed the copyright watermark in discrete wavelet transform (DWT) medium frequency coefficients of the host image by permuting the watermark image, and embed the authentication watermark in spatial domain to detect and indicate the counterfeit area clearly. It determines the location where the watermark can be hidden and modifies the strength of the embedded watermark adaptively based on images content. Furthermore, there is little influence on such application of remote sensing images as edge detection after embedding watermarks.
