Hello All,

One of my clients needs a software which cannot be copied to another computer. Yes, they want to store some valuable information along with the software, which they don't want to be copied to another computer and they also don't want to run this software from pen drive.

IMHO, this can be done by checking serial number of the hard disk. But, I don't know how to do it?

Can anyone did this before?

For data encryption, I am planning to use ENCRYPT function.

Thanks in advance.

With best regards.

Disk serial number can be easily changed by anyone to meet the 'original' that makes your application work.

For me, the best solution in that case, is to use an encrypted virtual disk and install the app. inside it.

ie: http://www.truecrypt.org/

Thanks a lot Master Roberto
I installed it. Now testing with it
With best regards.

This is new to me.

I too am badly in need of such thing..

Thanks for asking this Sudip.

We should establish an award for the forum users that do the best questions, inaugurating it with Sudip

Thanks a lot Master Roberto and Rathi When I was in school there was a back bencher (not me, he was sitting besides me ), who always asked irrelevant questions to disturb the class. Hope I am not playing the same role here

Ok jokes apart, I tested this excellent software, created an encrypted volume. I copied my app to this volume. It runs fine from there. But, how can I protect copying that app from the encrypted volume? (Yes, there are too much unused gray cells in my brain, I need more hints )

Thanks in advance.

With best regards.

I was a teacher for nearly twenty years and I can assure that, always there is one

But, it's still surprising to me that on the other side of the world, in very very different cultures, at last, the people behaves the same



If the operator is 'trusted' he simple should close the encrypted disk at app exit, If not, you are in trouble

Well... in such case you should collect info about the PC BIOS that can be not emulated (at least easily) on other machine.

Perhaps Grigory could help on this...

Hi,

Try


I hope that helps

THANKS!

May be this is too much. However...

Since truecrypt is also open source, can that be compiled using mingw and probably have a bridge for harbour so that we can use it inside our HMG application?
