Harry Robinson I have heard Windows XP has a sort of protection so that it cannot be copied. I also heard of users having to phone to get the code. Does anyone know how this really works? Is it efficient?
Also does anyone know of a good system to protect a TCL software?
Thank one thank all (June 1 2004)
See source protection. It's a good idea to run a search [L1 ] before creating a new page.
That page really doesn't cover this topic. Preventing an executable from being copied and used elsewhere is not the same problem as protecting source from prying eyes. One might argue day and night about the right & wrong of each, the possibilities for success, etc. But clearly they are not the same question, though both might come up in the same discussion.
To Mr. Robinson's question...my understanding is that XP obtains information on the hardware configuration and compares this information with the hardware present at boot time. This is, of course, an oversimplification, but that is the general concept. There is nothing to prevent a TCL app from doing something similiar, but to my knowlege it has not been implemented.
I know the Scriptics tools used a licence-key server system to control licencing. Perhaps something like this would suit your needs. Others would know more about it then me, and hopefully will chime in here ;-).
Harry Robinson ''Thanks so much for a very enlightening answer Mister ... (I'm sorry I did not see your name! :-)). I have been told the same thing about XP's protection: it does a sort of virtual digital prints. Very interesting!
The Scriptics tool sounds like the solution I am looking for. Thanks! No offense to supporters of open-code but bear with us we'll be trying to make a living with software so we just can't give it out.
