Abstract: The watermarking producing, inserting and detecting method of the present invention comprises: a watermark inserting logic in which images selected from various types of source images are divided, watermark is inserted using personal information and converted location into the selected image, and the selected image watermark is inputted into is coded and produced into a watermarked image; and a watermark detection logic in which the watermarking images selected from the watermarking images produced by applying the watermark inserting logic are divided, inserted watermark bit is extracted using personal information and converted location into the selected watermarking image, and the extract watermark bit and insert watermark bit are compared to each other to determine if the source image is converted or not. Therefore, by the present invention, fake and distortion of original digital media data can be accurately determined as well as the fake and distortion location.

Abstract: PURPOSE: A location calculating method between sensor nodes is provided to reduce an error of a location recognition generated by performing MDS algorithm. CONSTITUTION: A sync node or a server repetitively performs a MDS algorithm(S4). The sync node or the server obtains a relative coordinate of nodes. The sync node or the server changes the obtained relative coordinate of the nodes into an absolute coordinate(S5). The sync node retransforms the changed absolute coordinate into a WGS84 coordinate system(S7). The sync node obtains the absolute coordinate of the nodes in a cluster.
