Nigel - ask and you shall receive :) Section 7(3) A data controller is not obliged to comply with the request under this section unless he is supplied wit such information as he may reasonably require in order to satisfy himself as to the identity of the person making the request and to locate the information which that person seeks. Proportionality is the key and while it may be reasonable to ask for more stringent proof of ID for cases where sensitive data is involved this isn't, in my experience, always necessary. Working in a social care environment a lot of the personal data we hold is of a sensitive nature but as we have many requests from people well known to the department we don't always ask for ID - we know the requestor so there is no benefit in asking for proof of their ID despite the sensitive nature of the data requested. That said if we received a request from someone not currently known we would of course ask for proof of their ID, usually a copy of their passport or similar.

If you are a bank, as a matter of opinion, I think it is REASONABLE for you to ask for my passport/ID card as you have those already (or data of similar sensitity) by the operation of statutory rules (I.e anti-money laundering) (However, askin for these by post STILL does not stop id theft!!). If I make an SAR on a company or organisation like a spammer which SHOULD have no data, or marginal data about me, then sending such data is UNREASONABLE (again, IMO). Whether something is reasonable or not, is often irrelevant. The question is what is LAWFUL?? I have yet to find the relevant section of the Act. (Can anyone direct me to it?). But I seem to recall the expression "sufficient to identify" being bandied about. This is a LONG way from "*prove* your identity". It is not the same at all. I submit that name and address is normally "sufficient to identify" me in most circumstances. (Where you the data are stored agaisnt a previous address, then that address is would be required to be sufficient.) Ultimately it is a matter of construction and you can't decide on 'gut-feel' unless the word 'reasonably' appears in the law. You have to apply statutory interpretation to the relevant section. Anyone able to quote chapter and verse?
