QR Code to improve the protection against forgery of certificates

1 Requirements

To improve the protection against forgery of ILIAS certificates, it should be possible to add a unique QR code to each certificate, e.g. via a placeholder [QRCODE] in the certificate text.

To make the QR code unique it has to encode

• the NIC-ID of the ILIAS installation
• the object ID of the object which issues the certificate
• the user ID of the owner/recipient of the certificate
• the timestamp when the certificate was issued

Then, anybody should be able to scan the QR code on the printed certificate to validate its genuineness.

By scanning the QR code a message should be displayed to mark the certificate as valid. The message should contain the most essential information on the certificate. Following an additional link it should be possible to view the original certificate to compare it to the printed one.

One challenge:

The information on issued certificates has to be stored persistently. It should still be possible to validate a QR code on a printed certificate, even if its owner already left the institution (e.g. finished his/her studies and left the university) and his/her ILIAS account was closed and deleted.
The same problem applies when the test object, which issued the certificate, will be deleted (e.g. in the case it belonged to an elderly semester course).
