Meta Data re Personal Data

The metadata would reveal if the Report was edited after the phone call.

A forensic metadata would actually reveal what was written before the editing (if editing was discovered)


You are, I think mistaken.

If the file is a word document (or perhaps similar) then it may contain a revsion history. A simple email will not.

SAR may not be the way to get this metadata. See my first reply to this topic.

Yes, the file (Investigator's Report) is a document that would contain a revision history.

A revision history is not what is generally understood as meta data. Providing you with a copy of the file itself would also beg the question as to improper disclosure of matters relating to completely unrelated third pasrties, and begs the question entirely about whether a revision would be at anybody's request.

There is nothing at all in the fact pf a phone call to suggest that something wrong is afoot.

Meta Data is "data about data". It is the technical information that enables the separate data items to be connected in a usable way. Historically in computing it was considered to be data above 3rd normal form, though in today's world of big data that definition is less relevant. In this context the "meta data" seems to be the attributes associated with an electronic file. Companies have been using meta data and federation techniques to avoid data protection legislation for a number of years even in the US.

Would it not be easier to request the internal report with the source data? Its likely to still be held?

Can you please explain these normal forms and the various federation techniques.

They are all listed in this article under the see also section
https://en.wikipedia.org/wiki/Database_normalization

If you take Personal information and "Pseudonymize" (1) but maintain a hash of the difference from the real data , you can happily process personal information for business gain without it falling under the criteria of Data which is to be protected. GDPR (2) legislation tried to address this, but as usual the industry moves quicker than the legislation. It really all took off with the introduction of PCI DSS (3) which meant companies had to secure 1000s of systems holding card data, or replace the card data with a hash/index and store the real data once in a controlled secure way, which was obviously a lot cheaper. With the "cloud" you can distribute your bits of data in the same way that companies choose to distribute their revenue to minimise tax.

I believe that is perfectly normal. I don't believe it is a deliberate effort to obfuscate.
