An admin will also need to add this information to make it verified.

In that topic, I submitted some new information about Monster Trucks (Sony PlayStation): http://redump.org/disc/11534/

I got an answer in that topic from Enker:
"An admin would need to lock the barcode to make it verified.

The ring field cannot be locked until the 'Mastering Code' and 'Mastering SID Code' are provided. They are present on the disc, but require a strong light to see. There is no way to scan these codes from the black discs, so the ring cannot be verified."

Now, it seems like Enker was actually wrong, because I have successfully scanned the bottom (black or blue) surface of the Sony PlayStation-disc with a regular scanner + a 25 W halogen lamp.
I have also checked/verified the disc surface manually by holding it in front of the halogen lamp and looking at the Ring-surface to be absolutely sure that I haven't missed any information under the bottom surface (especially Mastering Code (Ringcode), Mastering SID Code and Toolstamp).

So, here is the addtional information:
Monster Trucks (Complete Ring codes):

Mastering Code (Ringcode)                                
DADC AUSTRIA<TAB>A0100219137-0101<TAB>15                                        

Mastering SID Code
IFPI L555

Toolstamp

Mould SID Code
IFPI 946A

Additional Mould Text

Keep in mind that the current information in the Rings-section of the game was submitted by me.
So please, edit (not add a new field for) the existing Ring-field to add the new information.
