We are printing certificates and diplomas in bond paper and we found some fraud copy of our certificates. The only feature we have for security is an embossed stamp in GPA, also we have printed 3 millions of blank certificate and printing over it using a crystal report format.

How are we verifying certificates in our existing system?

Can not verify from everywhere, because our main database is located only in center office and we are we have to verify 150+ certificates one by one everyday. Also 90% of the records are in file archives not in any database.

What we want? To prevent fraud copy of certificates, We have decided to use barcodes but still we need to locate our database everywhere and we can't do this now.

I have other options:

  1. Mobile SMS verification
  2. UV Ink
  3. Hologram

Since its bond paper, what feature can I implement on the paper to at least prevent it from duplicate (Not including the SMS verification because we can't afford it at the moment).

Interesting take on "IT" ;) –  Steven Lu Jun 30 '13 at 6:21
    
There's to primary problems with this question: (A) this question is about physical document security, not IT Security. And (B) it's a call for general discussion with no right answer. For these reasons, I don't think this is on-topic for this site. –  tylerl Jun 30 '13 at 6:53

It's on-topic (come on, information technology does not depend on the medium!) but poorly researched and unanswerable within the scope of a single Q/A webpage. Look at en.wikipedia.org/wiki/Security_paper –  Deer Hunter Jun 30 '13 at 7:54

IMO not being IT isn't really the problem. But the question is too broad. –  CodesInChaos Jun 30 '13 at 8:40

@tylerl All information security is firmly on-topic on Information Security, despite the restrictive name which we were locked in for historical reason. Conveying that a piece of paper is genuine is unambiguously information security and therefore on-topic. But I agree with other commenters that the question is too broad and best answered by an encyclopedia article or a book. –  Gilles Jun 30 '13 at 9:21
