WASHINTON (CNN) - If you thought the National Security Agency and big tech companies like Google were the only threats to your privacy, you may want to think again.
Foreign Governments may also be spying on you.
When Edward Snowden dropped his bombshell revelations about the U.S. Government's surveillance program, his story took an ironic turn. Snowden fled to China and Russia, nations long known for spying on foreign visitors.
Those countries are not alone, especially when it comes to your computer, phones and other devices. Many countries, even allies, consider them fair game.
According to Mark Rasch of Rasch Technology and Cyberlaw, "When you cross the border you're going to be carrying a bag and in your bag you'll have say your phone, you'll have your laptop computer. The border patrol agents in any country around the world have the right to take all of the data off of that drive."
Reporter: "Do people know that this is being done?"
Mark: "Most business travelers do not know that countries have the right to copy everything that's on your drive and all of your passwords that access your mail, your email, all your files."
Reporter: "So, this is routinely happening?"
Mark: "It happens all the time."
Whether openly or in secret, from border guards, to customs agents, to free wireless system at a hotel, all represent ways in which information can be grabbed from your electronics.
The White House has acknowledged the threat.
"We're going to have to work very hard to build a system of defenses and protections both in the private sector and in the public sector, even as we negotiate with other countries,” said President Obama.
So who and what are they after?
Journalists and lawyers are targets for the contacts they have; college professors and students for their state-of-the-art research; and business travelers because of internal memos, studies, and trade secrets that other countries and companies want.
"They have economic interests in wanting to learn trade secrets, business processes, new development, and new information technologies. If they can shave a year off of designing a new airplane engine, they can save billions of dollars for their economy," said Mark.
Avoiding such spying is not easy.
You can travel with cheap, disposable phones, encrypt everything on your computer, or better yet leave at home everything you don't absolutely need.
It is worth noting, most of us, in most of our travels will not be spied on, but if you work in high tech, the military or some other sensitive area, the odds do go up that when you go to see the world's sites someone may also be looking at you.
