How do we copy protect a CD?

[gopz]

There is a friend of mine who is making a software for schools and intends to sell it. How do we make sure that the CD cannot be copied...so that people wont just buy 1 CD and copy it and distribute it?

But those look like Audio CD protection...may not work for Software CDs

Try this:-http://www.freedom-to-tinker.com/?p=946

Btw every copy-protected CD / DVD can be copiled using Alcohol 120..

Offtopic:
Its at these kind of times, that people understand the problems of piracy,
and how it feels to have hard work ripped off.

Ontopic:
There are softwares that do the job, but most of them are paid,
besides , even if u manage to lock the cd, they will just use Alcohol or smthing else.
Instead just try telling people not to distribute the hard work done.
A junior of mine back in college did the same with a music cd he published.

say u use that software & a SMART kid cracks ur cd & ur work is gone ....

imo, instead of locking ...... y not keep an imp file of that sotware u created with u & before they use ur softy , ask 4 that file .....

& 4 each softy THAT imp file is diff ......

just my though .....

if suppose his product sell in UK then he will go to UK to give the file or email it.

And suppose if his s/w become some what famous then he is gone.
24 hrs sending that file.

LOL

imo u have to do Hard Work if u goes with this sugestion of ax3

imp file = less in size & just 4 activation via net .......

If the work means so much to him, ask him to buy a SecurDisc drive, all the LG Burners are SecurDisc enabled. It will allow him to protect his media with password protection, Digital Signature Protection, and Copy protection too!
