Be careful for what you desire
It sounds great - an identity which guarantees that it is YOU i.e. a person registered with the government, a bank, a doctor who is making contact with an online service. If that is where it stopped, it would be fine. However, when politicians get their hands on the concept it turns into something quite different like the National Identity register. For that, there would be thousands of people able to access your information, 1% (on average) being criminals. It was proposed that (as a starter only) with information to be added without your knowledge and with no means of correcting or challenging the information the following (I quote):
(1)For the purposes of sections 4 and 5 “personal information”, in relation to an individual (“A”), means—
(a)A's full name,
(b)other names by which A is or has previously been known,
(d)A's date and place of birth,
(e)external characteristics of A that are capable of being used for identifying A,
(f)the address of A's principal place of residence in the United Kingdom,
(g)the address of every other place in the United Kingdom or elsewhere where A has a place of residence,
(h)where in the United Kingdom and elsewhere A has previously been resident,
(i)the times at which A was resident at different places in the United Kingdom or elsewhere,
(j)A's current residential status,
(k)residential statuses previously held by A, and
(l)information about numbers allocated to A for identification purposes and about the documents (including stamps or labels) to which they relate.
Note that it fails to mention photos directly and the usual hassle of having to pay to update them on a regular basis.
This will permit a number of interesting consequences:
1. Criminals will be able to take your identity more easily since the information will be public (despite the governments best efforts).
2. If there is a criminal activity in or near any of the properties you have lived in, you will be hauled in front of a court to prove it wasn't you.
3. There will be many errors which you will not be able to correct - wrong addresses, wrong dates which will have nasty consequences in trying to get loans, take out insurance etc. etc.
Wouldn't it be nice if there could be an identity system which simply permitted you to identify yourself? In the uk IMPOSSIBLE - too many bureaucrats and politicians trying to create the police state.
