Abstract: A video encryption transform filter based on DirectShow and new encryption RCE
is proposed. First the RCE encryption algorithm was discussed, then how to apply the RCE
encryption algorithm to DirectShow and implement the video encryption was discussed
detailed. The experimental result and conclusion indicate that this solution meet the
requirement of application and provides high security, high speed encryption, and even there
was no redundancy data add to the video file.
