> And the biggest concern of all: How would they [the dementors] know
if they had found Sirius Black, and not some other person? <snip> Did
they have a "emotional footprint" they were looking for? 

HP fan 2008:
It seems to me that the basic thought pattern is the key. Harry was
focusing on Sirius's innocence when the dementor almost kissed him -
exactly the thought that Sirius was focused on at Azkaban. In
addition, when Umbridge sent the dementors to Harry in book 5, I
believe that she wanted them to kiss Harry - but she was completely
wrong about what Harry would be thinking of. Dudley's thought pattern
was probably closer to what Umbridge told the dementors to look for.
