Holodisc

A holodisc was a disc-shaped device onto which holographic messages could be recorded. It was possible to encrypt the content of a holodisc.

Morgan Katarn had recorded a message to his son Kyle revealing the location of the map to the Valley of the Jedi and the truth about Kyle's Jedi potential, and encrypted its content. Only WeeGee (and maybe a very skilled computer engineer) could decrypt it.
