WebAudio and video files were encoded with distinct cryptographic algorithms and then metadata were extracted from these cryptograms. The algorithm identification is obtained by using data mining techniques. Therefore, the procedure first stage performs the encryption of audio and video files using DES, Blowfish, RSA, and RC4 algorithms.
