The one problem you face is that some kid somewhere will crack your
substitution encoding and post a reader to all the cracks and warez
groups if your product captures even 1% of the market in your niche.
Your users will then view your product as worthless when their 13 year
old shows them the reader. A reputation lost is hard to regain. To
maintain profitability and marketablity you'll need a little more added.
That same programming loop you'd have in the code performing the
substitution could easily be doing some excryption. Your end user still
won't see it.

Anyway, you may have already seen this, but if not, web page that
encodes to barcode: http://www.idautomation.com/java/linearservlet.html
