Security Question

Hi:

In the past I have installed a couple of my programs in school servers and in the coming weeks I’ll be installing another program in another school server. However, this time the school in question has several branches in the rest of the country, which presents the possibility of illegal copying from the part of the school.

How can I make sure that once I install the program no IT guy from the school can copy it and install it free of charge in the other school branches?

Any suggestions?

Thank you for your attention.

What program are you installing? You could probably hide some code that reports the domain of the site being browsed back to you so that you could see if it was copied. You could probably also add code so that it only works on a particular domain, although that code could probably be easily found and deleted.

Ray:

The program I’ll be installing is the one you have been recently helping me with (Administrative/Academic Student Records) It will be installed in an intranet server, therefore not available on the WWW.

I’m assuming the IT guys would have to copy the code and files installed in the first school server so that they could “paste” them on each of the other school servers across the country.

Again, I have no evidence that they would try to do that. I’m just looking for precautionary protective measures, just in case.

Thank you for your attention.

You could add code to check specific $_SERVER variables to match the installed server... but realistically that could be removed by anyone that knows what they are doing.

There is no real security measure you could employ particularly on sites that can't access the internet. You may just have to depend on clear license terms and the integrity of the organization.

Ray:

I have no real reason to believe they will try to copy it, but if there had been any measures to make sure they don’t do it I would have taken them.

Thank you for your time and attention
