Claim Text:
1. A video cryptography system comprising: (a) host computer system (HCS); (b) pseudo random number generator (PNRG); (c) mobile user device (MUD); and (d) computer communication network (CCN); wherein said HCS is configured to generate a random video image (RVI) with said PNRG; said HCS is configured to transmit said RVI and stream video media content (VMC) to said MUD through said CCN using a non-secure communication channel; said MUD is configured to present said VMC and said RVI on a display for an end-user; said RVI has a polygonal shape that is defined by data entered by said end-user on said MUD; said MUD is configured to accept graphical user interaction (GUI) on said display from said end-user via a user input device (UID) on said MUD; said MUD is configured to monitor said GUI to determine if said GUI intersects said RVI; said MUD is configured to collect a random gesture data (RGD) from said GUI based on the activities of said end-user with respect to said UID; said MUD is configured to transmit said RGD to said HCS; said HCS is configured to receive said RGD and use said RGD as a seed for a cryptographic communication algorithm (CCA); and said HCS is configured to establish secure communications with said MUD using said CCA.
