This paper discusses protection of the copyright of audio signal which is belonging to Egyptian Radio and Television Union (ERTU). It is used to protect it through the cloud and allow the Authorized Groups (AuthGs) to get benefit from. It is done using watermarking techniques based on Discrete Cosine Transform (DCT). Many tests are performed to compare between the original and watermarked audio to insure the robustness of the process and then the high performance of the cloud which is done. Moreover, these tests are applied to insure the source of the audio and detect if any changes are made. This also overcomes the difficulties of distance for all AuthGs.
