When I travel for work, I undertake what some people consider extreme measures to protect proprietary client data from theft by officials at international borders. These officials do not need warrants to seize or examine anything in your possession when crossing a border and that makes border officials excellent spies. This issue arose recently regarding the actions of the US border officials:
In Canada, one law firm has instructed its lawyers to travel to the United States with “blank laptops” whose hard drives contain no data. “We just access our information through the Internet,” said Lou Brzezinski, a partner at Blaney McMurtry, a major Toronto law firm. That approach also holds risks, but “those are hacking risks as opposed to search risks,” he said.
Creating a “blank laptop” entails more than just hitting the delete key or even using a utility to overwrite existing data. The hacking risk is also greater than most people realize, especially with wireless connections. Even with secure end-to-end encryption, traffic analysis can yield very useful intelligence.
