Simple URL encoding technique?

My JSP application asks users to visit a web site with a URL of the
form <www.example.com?column=100&row=200>. This makes it far too easy
for an intruder to derive a different column and row that may yield a
real location to which they should not have access. Is there an
existing method that can "obfuscate" (and de-obfuscate) the column and
row number. It is easy to concatenate the row and column numbers if
that is a desirable first step. I don't need a high level of security
because the there is nothing of real value at the destination; I just
want to foil a casual vandal.
