Looking for source of information in topic on tnp3xxx toys

Does anybody know where the following information was sourced from (near the bottom of this topic: http://www.proxmark.org/forum/viewtopic.php?id=6165)?

Imaginators signature

Blocks 2, 4, 22 and 3E are a Ed25519 signature (just like in the Kevin Valk thesis). The message that gets signed is the first two blocks (0 and 1). The number 51 also seems to correspond to a yearcode (5) and keyindex (1). I also found that only one key is currently in use. The public key to verify the signature is: 8E567B03734294EE2E491C3A2DEDA46B9E1858C08924699860D229E01287253B
