British people were told yesterday that the personal data of nearly half the nation has “gone missing”. In the newly merged department of Inland Revenue and Customs, a “junior official” downloaded the personal details, including bank account data and National Insurance numbers, of 25 million people and placed all of it on two unencrypted CDs.

The official then put the CDs in an envelope and posted it. The package wasn’t even registered so couldn’t be tracked or traced. It’s now officially “lost in the post”.

Alternatively, it may have been stolen to order by organized crime. We have been told, the official is now under guard in a “safe house” to protect him or her against the media, and presumably criminals seeking “to make him an offer he can’t refuse”.

This morning there’s huge panic all over the UK as people wake to find their bank accounts and personal identities compromised in the most dangerous way possible.

Once again we see the perils of allowing a central administration to accumulate vast quantities of information through a system of universal benefits more in tune with the Soviet era than the distributed nature of data in the age of the internet.

What can you do to protect yourself against the kind of scam everyone in the UK is now worried about?

1. Check your bank and credit card statements for the next 5 to 10 years. Criminals can lie low and strike when banks get sloppy again.

2. Change your online banking password, especially if you use family data as a memorable word.

3. Look at your credit report. The information in the Child Benefit Agency records is enough for a criminal to apply for loans, credit cards and even mortgages in your name, as well as other forms of credit such as mobile telephone and catalogue accounts. Your credit report lists all your credit commitments and recent applications for credit, so you can instantly see if someone has been trying to use your ID.

Apart from that, you are at the mercy of Government officials and your bank’s security measures. Ultimately, they must take responsibility for protecting their customer’s data.

Unfortunately, British Government agencies routinely break its own Data Protection Act. The shambles goes on.

The long-expected credit crunch linked to massive failure in the American sub-prime market really hit home yesterday.

The European Central Bank, regulator of the Eurozone group of countries, piled into the markets with $130 billion of cheap, emergency credit.

The move, the biggest central bank intervention since 9/11, came after reports that commercial lenders were desperately hauling back the supply of loans. The French giant BNP Paribas suspended withdrawals from three of its investment funds because of their exposure to the U.S. sub-prime market, saying “There has been a complete evaporation of liquidity” from credit markets, which could escalate into a worldwide credit squeeze.

Rumours were rife of impending fund meltdowns and banking collapses. Trevor Williams of Lloyds TSB said, “Liquidity has dried up basically. It’s a moment of panic.”

Nick Sparks, risk manager at F&C Partners, said, “People have got caught out. There will be more pain to come.”

You have been warned.

I’m assuming you’re not one of nature’s money launderers, and all your financial dealings are honest ones. How then would you avoid clandestine attempts to turn you into a launderer of stolen cash?

Here’s one solution : reject all emails that ask you to help with transferring a large sum of money from one place to another, neither of which you have any connection with.

We’ve all received them : our inbox pings and we find an URGENT MESSAGE (they’re often in capital letters), from Mr Winston Churchill Obongo, President of Barclays Bank, Nigeria, who pleads for our help in transferring a $10m inheritance to a destitute widow in the USA/UK, or wherever we happen to live.

We delete them, of course. Only the most credulous or ill-informed people on the planet would fall for such a crude ploy.

Now, however, something more insidiously believable is doing the rounds. It pretends to come from the genuine clothing company, Harvey’s of Oldham, England. Its sender calls himself, Ronald Harvey. He says his company moves money around the world, but falls foul of a 25 percent “international money transfer tax” on businesses. Individuals, apparently only pay 7 percent.

You can see where this is going. You are the key to reducing Harvey’s costs by 18 percent. All you have to do is accept funds into your bank and use a money transfer firm to send it on around the world. You receive 10 percent.

You may, of course, wonder why you’ve been singled out, but the lure of 10 percent of whatever millions are shooting through, is a persuasive one. The snag is that in Britain banks by law demand to know where any sum over £10,000 has come from. Nevertheless, a regular transfer of £9,900 would get through the cracks.

The bottom line is that the money transfer tax doesn’t exist and the money will be stolen. By getting into the loop you’ll be rendering it squeaky clean for the recipient.

Ronald Harvey turns out to be “Michael” with a distinctive African accent. The scam has nothing to do with the Oldham workwear firm.

Researchers at MoneySupermarket.com have unearthed 110 charges and fees on basic financial transactions that customers may be liable for.

In the UK, penalties hidden in the small print can add up to more than £8 billion ($16 bn) in revenues for finance companies, credit cards and banks. And a similar situation may also exist in the USA.

The website looked at five common financial products : current accounts, mortgages, loans, credit cards and savings.

Mortgages, with arrangement, booking and valuation fees accounted for 46 of the total. These have risen to around £1000 ($2000) in the past year.

Normal bank accounts can levy 32 penalty charges, while credit cards account for 16 fees. Loans attract up to 11 charges.

Stuart Glendinning, Managing Director of the website, said : “It is unbelievable that five financial products can be the root of so much penalty pain.”

Nick Gardner, a director at Chase de Vere, the mortgage advisers, said the range of fees embedded in home loans is “cunning and completely unacceptable. The headline rates may be coming down, but the number and scale of fees have risen enormously.”

Maybe it’s time to get that old magnifying glass down from the attic.
