How to build an application with MACHINE ID PROTECTION?

Status
Not open for further replies.
Dear all,

I've developped some video tutorials using
Camtasia Studio v2.1 & ACA Capture Pro v4.31.
They are simple .avi
files. Now I want to distribute them by making
an application and also protecting it (I mean,
the distributable CD) with "MACHINE ID PROTECTION"
feature so that everybody can view it after
entering the proper Serail(Generated based on
the MACHINE ID which differs from PC to PC &
also OS to OS), but nobody can copy it or, rip
the .avi tutorial files inside. Now, I am going
to discuss it in detail.

1. My tutorial files are simple .avi files which
is playable in Windows Media Player interface.
I've seen in many tutorial/presentation CDs
(e.g. intro games on any Game CD, or, diff. videos
in Encyclopaedia Britanica CDs etc.) that the video
files are encrypted. You are not allowed to play
those video files(I remember, some of those
mysterious video files are in .bik format) using
standard video player(say, Windows media player).
Now, I want to know how these people create those
mysterious video files? Which application they
use? Or, they use some converters to convert
our known video files(.avi, .mpg, .mov etc.) to
a mysterious format which can only be seen/played
using their interface(or, application) only???

2. Next thing I want to know is how to protect an
application by MACHINE ID PROTECTION??? I've seen
in many appz (say, Pinnacle Studio 9, 3D Studio Max 6,
Autocad 2004 etc.) that, during installation u need
a serial. After installing the app, an authentication
code is req. which is to be calculated using MACHINE ID
of the corresponding PC. I've also seen that MACHINE ID
varies from OS to OS in the same PC (e.g. Pinnacle Studio 9).
Now I want to know, is it possible to protect my app
which will contain some video files and a menu(an .exe file)
using MACHINE ID protection??? Plz note that, I want to
distribute my app as a shareware (a 14 day trial). After
the trial period is over, the app should be stopped. And
if proper Activation Key is entered, it should resume
its activities. Is it possible at all? If so, plz
guide me :(


thanks in advance,

What do you mean by machine id? Machine is made of various parts. So at most you can find the serial number, etc of all parts and make a composite number.

But what if someone plainly changes RAM stick or processor? Should they call you with problems :roll: I guess the best way is to use the hard disk serial number. I have a code in VB to find that out. Let me know if you want that :)
 
dear tuxfan,

if u ever install Pinnacle Studio 8 or, 9 or, Discreet 3D Studio Max 5 or,
later, u would know what do i mean by Machine ID Protection !

and again, if u have some codes to share, then plz go ahead for lots
of developpers like me !

Dear friends_for_all, I have never installed those softwares, so I really don't know what is Machine ID Protection ;)

As for the code. Here's the contents of the FRM file. Open notepad, put this code in that file and save it as .frm file.

Code:

hey dude!

you can try Visual Protect from *www.visagesoft.com/products/vp/index.php. it's grat tool for licence management u wanted. Though you have to chk out whether it helps u really or not.
 
thank u onlyutkarsh for your valuable addition. i'm downloading it right
now...

i've tested the following...

SerialShield
ShareGuard Copy Protection v2.1
SoftwareKey Trial Creator v1.10
SoftwareShield System
Hardkey License Manager v3.2
Smart Protector Pro v4.1
The Armadillo Software Protection System v3.60

these applications r wonderful if u use Visual C++ or, VC.NET
or, Delphi. But not very useful in my case.
