Looking at some examples given in the linked pages on this here, it stands out that there is a structure to each of the 32 bit records in this data. The first 16 bits are nearly random, but the second set obeys some rule: the third octet is a low number and the hole set of records is sorted by that. The fourth is always zero. If this is intended to be a kind of tracking identifier, this structure is a bit odd. Intuitively, I would rather interpret this as a list of tags that are stored in-band with the image.
