Internet

Maintain a number of alternate personas on the Internet that give you access to web mail and other services should you ever need to use them.
If you need to use the Internet, use a public access point, such as a cybercafe, a public library that doesn't require an ID, or a college computer lab that doesn't require an ID. Make sure that you do not access your own Internet services from the cybercafe - use an alternate persona.
If you need to view material that you do not wish to be associated with as part of the server logs of your Internet service provider, use a cybercafe.
If you use cybercafes as part of your communications, try not to use the same one.
If you have a laptop computer, and you wish to mask your location, let someone you trust use it online whilst you are away on sensitive work.
