Protecting PHP programs from theft?

I am looking for recommendations for the best PHP copy protection. The key feature in the copy protection is to able to be able give people UNIQUE serial numbers so that I can control who installs or uses the scripts on their web host. This way unauthorized users won't be able to install or run the program. Someone suggested this program: codelock.co.nz/tracker.html but am wondering if there are any other solutions.

What I need to happen... i.e.
1. Jimmy uploads the php files to his website
2. Jimmy runs the program and then it asks for a serial number
3. We give jimmy serial number and to unlock it so that the script will work
4 If Jimmy tries to give the script to his friend Teddy, Teddy won't be able to use the script since he needs the serial number which is unique for each person and can only be used one.

Thanks!

  • Hi Hummer,

    The level of protection you implement should be in direct proportion to the skill of the people that are going to use your s/w.

    In otherwords, if you are goijng to provide code to "geeks" then no matter what protection you use, someone can break it..

    One of the better php encrypters if the Zend one, and its works well, but just the otherday I found a site that allows anyone to "DeZend" script back to it orginnal code (all for free).

    Now that encrypted code is now freely available on the web.

    So if your audience is programming newbies, or people who know very little about PHP, then apps like CodeLock work well and should deter 95% of your potential code thieves..

    Don't stress about the remaining 5% becuase you can never stop them anyway.

    The way I approauch programming in all that the people that steel your code where never going to buy it anyway, so what have you lost.. NOTHING!!

    But if you provide outstanding service, support etc, people will be encourage to pay full price to get what you give.. It works for me!!

    Just my 2c worth

    take care
