"Anonymizing" data is a myth; stripped or hashed columns can usually be recovered by correlating the remaining data with other data sets.

Which admits that the data probably is recoverable, just "economically infeasible". Do you have proof of that claim? Unfeasible for who? In general, the difficulty of re-correlating data goes down as the amount of data grows.

DJB once described[1] hashing as "magic crypto pixie dust" that "takes personally identifiable information and makes it incomprehensible to the marketing department".
> A demand to forget has to show that I have data on that person.
So you're trying to launder data to circumvent the letter of the law. This kind of scofflaw, antisocial attitude is how you attract reactionary, heavy handed regulations.
There is no other data set to correlate. Simply all the external context data is not recorded anywhere. Not even in logs. Unless some higher agency is going to hack some network driver to pick up the tcpip source, etc, I don't see how the data could be associated with datetime and location. This is why I was talking about "economically infeasible".
Data scrambling doesn't mean hashing. Sorry, here you are wrong. It's a on-the-fly frequency/timedomain scrambling, means someone has to physically, again, access a server and pick up from the memory the algorithm. And no marketing department, all research here!
The other stuff, I wound't reply, but let me asure you, there is no law circumventing. We are open and if someone can pinpoint of some personal data, there is no issue removing it.
