Wireless multimedia delivery is becoming increasingly important in today's networks. Due to the explosive growth of the Internet and increasing demand for multimedia information on the web, streaming video over wireless networks has received tremendous attention from academia and industry. Data origin and data integrity authentication are very important factors in video security. Extensive research has been conducted in this area with different techniques. In this paper, digital signature techniques are reviewed for authenticating video.
