Data sharing

The question is too general, as we have seen from the recent Facebook revelations, firstly we need to know what detail of data is being held and further what detail is proposed to share.

How about putting some effort in rather than asking simplistic questions that can't elicit a reasoned response.

I give my data to one firm. If they want to share it, they should ask me and pay me for it if I consent of course. Otherwise I don't wish my date to be used by any other firm.

We never had a debate about the Orwellian rollout of CCTV 30 odd years ago. In the same way, we seem to have surrendered our personal data without any great demur.
The problem is that the benefits are tangible by way better services, while the risks seem more distant.

Working in IT as I do, in system quality and security, I see every day how incompetent some organisations are in securing data even within their own organisation. GDPR will go some away to improve that, with increased fines and a wider range of controls. The fact is however, that tackles issue since they've happened. The safest way to ensure that my data doesn't get lost - I don't agree to its being shared whenever I have the option - sadly, not often enough with government agencies who frequently have exemptions from key legislation.

As for the private sector - I'd rather hand out my ATM card and pin number on the high street. At least that way, I'd know when to expect being fleeced, instead of waiting for the surprise.

Data should not be shared without express and specific permission.
My view is that all those involved only care about money and would only such information for personal gain and not for the good of the people.

Look at the Facebook / Cambridge Analytica fiasco for example.

No personal, private information of any kind should ever be shared for any reason by any public agency. So called sensitive data (e.g. post code, date of birth, ethnicity) when used together may identify individuals, and this is exactly what private organizations want and use for multiple purposes none of which are in the control or consent of the individual. Therefore, the only way to truly prevent individuals being identified is not to collect, store or share any information in the first place.

I am against personal data being allowed to be supplied to anyone. This includes by the Electoral Roll.
I think it should be law that if any authority or company requests personal data of an individual to any company, then the company that has this personal data on their client must be legally made to request the authority of the client as to if they wish their personal data to be supplied. This should be the same for any social media and or websites that individuals (clients) use.

I constantly get unsolicited mail for companies (Capital One for example), emails (companies that use LinkedIn for example) and even calls when I have never contacted them or enquired about their services

As I see it this is a breach of the Data Protection Act as Personal Data should be personal for that individual

Currently I would not trust them. I think given the budgetary constraint on local government there is no hope that they would share data in a way that was compliant with the relevant legislation, which (as the recent Facebook scandal has revealed) is completely out of date and inadequate anyway.

I'm not opposed in principle but I'd have to be convinced that there was a proper regulatory framework in place and that it was enforced, and currently we are just a long way from that point.
