Technology is, of itself, neither good nor bad. What matters is what we make of it. Lets see what might actually happen when governments and businesses gather and use personal information:
In the UK the 'database state' is emerging - the tendency to try to use computers to manage society by watching people. There are many interlocking government plans that do this. Together they mean officials poking into private lives more than ever before.
All the databases could be linked to, or indexed by, the National Identity Register (NIR) that is the main aim of the 'ID cards' scheme. The NIR number would be the key to an individual's life. And by "information sharing", what they tell one public servant could be passed to anyone.
The government call this: "Transformational Government" which sounds OK - until you realise that what is being transformed is not government but its power over you.
In the USA Muslim Americans have been branded as unfit for travel using no-fly lists or are otherwise subject to racial profiling, a practice that is condemned in other contexts for its manifest unfairness. The same practice has been rightly derided in the UK where Civil Rights groups have suggested that the profiling of UK asian air passengers means a new criminal offence is emerging- "travelling whilst Asian"
I can see only advantages, provided that your ID no.-related data is restricted to those who need to know.
And there's the problem - who needs to know? What should they know? What are our rights? How can we prevent those who have no right to know about us getting hold of our information? Those are not decisions I want a government to make on my behalf.
The devil, as they say, is in the detail.
