The audit we have in the bundle at tab 10, dated August of last year. It was obviously reporting on a Google privacy report, no doubt dealing with the matters you've just outlined, and the overall conclusion that I'm looking at reads:
"The audit has provided reasonable assurance over the accuracy and findings of the privacy report as provided by Google Inc. to the Information Commissioner. It has also provided reasonable assurance that Google have implemented the privacy process changes outlined in the undertaking."
It went on to identify some scope for further improvement and records the fact of improvements which had taken place.
