I'm trying to find out whether the AMCV cookie can be used to identify unique sessions - specifically so we can sessions between Adobe and a 3rd party tool (we can pass the cookie ID through to it). 

 

I know the MCAAMB part of the cookie is the encrypted Audience Manager 'blob' but I'm not clear whether it is consistent across a session and if it then changes from one session to another.  All the other elements of the AMCV cookie appear to be static across sessions for the same visitor on the same day, whereas I can see the MCAAMB part does change, I'm just not sure if it changes per session or in some other random way.  Any info, gratefully received!
