Sovereign: Canadian Customs wants your Laptop, too …

Published on The Sovereign Society, by Mark Nestmann, January 18, 2010.

U.S. customs authorities have assigned themselves the authority to copy all data on your laptop or other electronic device when you cross a U.S. border. I wrote about this policy last year.

Now, customs authorities in Canada (and other countries, especially the U.K.) are getting into the act. I’ve received reports from several sources (among them from J. J. Luna, author of the classic How to be Invisible) describing intimidating encounters at the Canadian border. Luna reports that after being routed into a secondary inspection queue, customs officials forced him to reveal the passwords to his two laptops and USB flash drives. Then, they disappeared with these devices in hand for nearly an hour, presumably to copy and inspect them. 

Your smart phone may be subject to the same type of inspection, and all your photos, text messages, online searches, and calling records copied onto a customs database.

To avoid a border inquisition, the best precaution is not to carry any electronic device across an international border. For most people, this isn’t practical, so the next-best strategy is to carry only “sanitized” devices.

I also have an “unlocked” cell phone I use only for international travel. When I arrive in a new country I purchase a domestic SIM card from a local phone dealer. This not only protects your privacy at the border, but also insures your domestic carrier has no record of your international calls. And, it eliminates roaming charges.

If you do carry your cell phone across the border, delete any photos or text messages you feel to be even remotely controversial, and then reset it to factory settings. You can find instructions for doing so at

What if you need access to confidential data while traveling internationally? One option is to upload a zip file containing your data to a commercial backup service, such as Carbonite (  Be sure to encrypt the data before uploading it, using a product such as PGP Whole Disk Encryption ( or True-Crypt (

Another option is to send an encrypted USB flash drive to your destination via courier, and send it back via courier when you’re ready to return home. I’ve done this several times without any problems … (full text).
