内容記述 The digitization of E-learning sources makes it an easy target for frauds, conterfeiting and content stealing. In this paper we present a new technique to deal with the security problems of e-learning content, its authentication and Digital Right Management. The proposed technique is done by inserting\na digital logo image, which serves as watermark signals, in the audio stream of E-learning material. This technique is based on Modulated Complex Lapped Transform that was selected for its audio reconstruction properties and the extraction of the watermark is performed using an Independent Component Analysis algorithm. To demonstrate the effectiveness of the proposed method, a real world implementation has been done and the algorithm shows quite good visual and audible quality in watermarked content, as well as a high robustness against common signal processing attacks.
