A protoype algorithm: PINVOX (â??Personal Identification Number by Voice") for on-line certification is introduced to guarantee that scholars have followed, i.e., listened and watched, a complete recorded lecture with the option of earning a certificate or diploma of completion after remotely attending courses. It is based on the injection of unique, randomly selected and pre-recorded integer numbers (or single letters or words) within the audio trace of a video stream at places where…
