In a critical report, the Parliament members said the government and industry have a "laissez-faire" approach to online crime that could lead to an "economically disastrous" loss of public confidence in the Internet.
With computer fraud growing more sophisticated, people have little hope of protecting themselves alone, the House of Lords' Science and Technology Committee said.

The lawmakers said that industry--from software makers and Internet service providers to banks and shops--must do far more to protect customers.
And they criticized the government for insisting that responsibility for security rests with Internet users, who are often faced with a "bewildering" set of options.
"This is no longer realistic, and compounds the perception that the Internet is a lawless 'Wild West,'" the report said.
The government must work with the European Union to see if more responsibility for security could be legally handed to computer and software makers, the report said.

Senior police must get the extra funds needed to launch a central e-crime unit and a Web site where people could report online offenses.
The report also highlighted the lack of clear figures on e-crime. The government should also make sure the courts are aware of the seriousness of the problem.
"The choice is either to intervene now...to keep the threat to the Internet under control, or to let it grow unchecked, and risk an economically disastrous, long-term loss of public confidence in the Internet," the report concluded.
