I don't think so.  I actually haven't seen any solutions to the problem
as propounded.  All the "solutions" I've seen don't prove anything to
anyone until after the "proof" recipient has found Waldo - this may
have been acceptable by the intent of the original author of the
problem, but it's sure not how I read the wording.

Note that this is completely independent of whether the other person
can be trusted to not peek.  If peeking makes a difference, then I
don't consider it a valid answer to the challenge posed, because it
means that the purported solution does indeed give away information.
