ok experts

i have written a new system that creates a worksheet called Data - the
contents of data are created from forms and VBA - my question is : can the
contents of a range be given a DISPLAY ENCRYPTION so that a user can not go
to the cells and see the contents

I should add that although this appears a strange request the owner of the
vba system does not want to reveal how the system works so thus hiding data
is a good idea - i guess he does not want his ideas copied

can this be done ???? or how should i address this issue ????
