Is it possible to encript or password protect individual layers in InDesign? I know that you can lock layers but I need to supply .indt or .indd files to a client with specific information, ie: indicia's, non-printable areas, master items etc., that must have no possibility of movement. They would then build their creative layout around those stationary items. It's too easy to unlock layers and mess with the items using the little lock icon. Any other suggestions would be appreciated also.
Thanks
