Can we enable licensing facility for our customized forms and report...?

Question

He All,
We have a product and we frequently used to send customized forms and reports to our customers through the shipment team after QC certified. But some of the customized forms and reports have sent to the customers without their knowledge from the development team, it is creating a big problem in the customer site.
We would like to know that is there any facilities to verify that this shipment has come from through proper channel or not if not they should not open. Is there any license kind of thing that we can do..? If I run some exe file which will check that and let the customer to use it..?
If any one have the knowledge about this kindly share with us. any kind of information regarding this can be appreciated.
With Best Regards
Thangaraj

Answer 1

So you want the customer to be able to check if the forms where shipped through the proper department from your company?
First thing that comes to my mind is to pack all the Forms in a JAR file (which is basically a ZIP file) and sign the JAR file with the jarsigner tool. To sign the JAR you need access to the private key that is in a keystore that's only available to this single department. The customer can verify if the JAR was signed with a proper certificate.
You could issue your own certificate to do this but requires the user to also first import this certificate so it is trusted. You could also buy a commercial certificate from a vendor like Verisign but there are costs involved.
Just google for jarsigner and keytool to get the idea.
