New Jersey ? Convicted sex offenders who used the Internet to help them commit their crimes will be banned from using the Internet under a measure signed into law Thursday.

The bill applies to people who, for example, lured a potential victim through e-mail or other electronic messages. It also affects paroled sex offenders under lifetime supervision, but exempts computer work done as part of a job or search for employment.

Under the law, sex offenders will have to let the state Parole Board know about their access to computers. Those caught using the Internet would face 18 months in jail and a $10,000 fine.

Convicted sex offenders will have to submit to periodic, unannounced examinations of their computer equipment and install equipment on their computers so their use can be monitored.
