What Is PRISM? A Little Knowledge Helps You Prioritize Your Privacy
PRISM came about because of the Patriot Act, which was a reaction to 9/11. It is a program run by the National Security Agency (NSA), ostensibly to collect intelligence from foreign terrorists or from people working with foreign terrorists. That's an important distinction because it's illegal for the government to collect information on domestic citizens without a warrant. It's not as if the NSA doesn't know that. After all, it's the Fourth Amendment. The problem is that the NSA doesn't seem to care all that much about our constitutional rights when it comes to PRISM.
What Can I Do to Protect Myself?
First, you want to ensure that your Internet communications are encrypted. The best and easiest way to do this is by using a VPN. A VPN offers you other protections as well; for one, it obscures your IP address, which means it's difficult to trace traffic back to you. Well, it's difficult as long as the vendor doesn't keep any logs of personal information, such as is the case with ZenMate. A VPN can't keep the NSA from forcing companies to comply, but it can help you provide it with less data to start with, and it can keep your data from interception.
