Need to hide the video downloaded from server in Mobile Device

Hello,

I am looking to have the videos uploaded to the web server and then download it to my mobile device. I am successful to do that. But As I see the video is visible in the android device by other video players as well as the file locator, I am looking to hide that video OR do something so that none of the movie players can play the downloaded video Nor can be viewed in the file locator.

Please do suggest me the way to achieve this task.

Thanks
