摘要：We present new approaches used in development of the demo version of a WEB based client/server system that contains an archival fund with folklore materials of the Folklore Institute at Bulgarian Academy of Sciences (BAS). Some new methods for image and text securing to embed watermarks in system data are presented. A digital watermark is a visible or perfectly invisible, identification code that is permanently embedded in the data and remains present within the data after any decryption process. We have also developed improved tools and algorithms for analyzing of the database too.
