This video highlights one of the problems that the National Identity Scheme(NIS) is likely to make worse.
Whilst the above scenario could happen (I think it is quite likely to happen), the following have happened and involve similar problems with existing government databases:
- Tax office worker passes address of battered wife on to ex-husband.
- Doctors betray forced marriage victims to their families.
Many other examples can be found via this Magna Carta Plus article.
The NIS will make these problems worse by requiring people to register changes of address (on pain of penalties upto £1000), by storing data in one central database accessed by all public bodies and by facilitating the cross-linking and sharing of data by those public bodies.
