M: I wouldn't be surprised, because, you know, it's the easiest way to communicate with other users over a network.
W: Is it? But I was told that we must set up an E-mail system on the network before we can communicate with other users. Is that true?
M: Yes, it's not tough to create such a system. However, you need some hardware and software to support it.
W: Let me know the hardware needed first.
M: A computer and a line that connects your computer with the Internet.
W: All right. I was told that I need an account for my E-mail. Where can I get it?
M: You can contact an ISP, I mean an Internet Service Provider, to get an account.
W: How much do I have to pay for it?
M: It varies. You can also get a free E-mail account if you don't have to consider too much for the security of your mails. I know many people prefer free E-mails and they say their correspondence through that kind of account doesn't involve commercial information needed to be strictly kept secret. You can get such a free account simply at home if you have got access to a website with such a service.
W: It's so convenient. I may prefer the free E-mail. What about the software?
M: You don't need any additional software. Just the IE, the Internet Explorer, bound with Windows, the operating system.
W: Thank you so much for your help.

Consumer activists are pressing Congress for better privacy laws without much result so far. The legislators lean toward letting business people track our financial habits virtually at will.
As an example of what's going on, consider U.S. Bancorp, which was recently sued for deceptive practices by the state of Minnesota. According to the lawsuit, the bank supplied a telemarketer called Member Works with sensitive customer data such as names, phone numbers, bank-account and credit-card numbers, Social Security numbers, account balances and credit limits.
With these customer lists in hand, Member Works started dialing for dollars-selling dental plans, videogames, computer. software and other products and services. Customers who accepted a "free trial offer" had 30 days to cancel. If the deadline passed, they were charged automatically through their bank or credit-card accounts. U.S. Bancorp collected a share of the revenues. Customers were doubly deceived, the lawsuit claims. They didn't know that the bank was giving account numbers to Member Works. And if customers asked, they were led to think the answer was no.
The state sued Member Works separately for deceptive selling. The company defends that it did anything wrong. For its part, U.S. Bancorp settled without admitting any mistakes. But it agreed to stop exposing its customers to non-financial products sold by outside firms. A few top banks decided to do the same. Many other banks will still do business with Member Works and similar firms.
And banks will still be mining data from your account in order to sell you financial products, including things of little value, such as credit insurance and credit-card protection plans. You have almost no protection from businesses that use your personal accounts for profit. For example, no federal law shields "transaction and experience" information--mainly the details of your bank and credit-card accounts. Social Security numbers are for sale by private firms. They've generally agreed not to sell to the public. But to businesses, the numbers are an open book. Self-regulation doesn't work. A firm might publish a privacy-protection policy, but who enforces it?
Take U.S. Bancorp again. Customers were told, in writing, that "all personal information you supply to us will be considered confidential". Then it sold your data to Member Works. The bank even claims that it doesn't "sell" your data at all. It merely "shares" it and reaps a profit.
