A short while ago the US House Judiciary Committee amended House bill H.R.1981 “Protecting Children From Internet Pornographers Act of 2011” so as to require ISPs in the United States to retain for 18 months a broad range of data about customers and their online activity. (It would seem that the version currently available on LOC’s Thomas does not yet reflect the changes.) To quote from the brief story by Conor Friedersdorf in The Atlantic:
…the firm that sells you Internet access would be required to track all of your Internet activity and save it for 18 months, along with your name, the address where you live, your bank account numbers, your credit card numbers, and IP addresses you’ve been assigned.
. . . .
Even more troubling is what the government would need to do in order to access this trove of private information: ask for it.

A similar bill has been introduced into the US Senate.
