Global surveillance disclosures made by Edward Snowden in 2013, raise the awareness for keeping personal information and mail stored online secure. The hype that followed these events is so big, some parts of the controversial Patriot Act lacked Congressional approval, and they expired on 1st June 2015. In spite of this, other parts of the Patriot Act are still valid and global surveillance is far from being over. It should be noted that government agents are not the only people who are trying to get their hands on people’s mail and personal information. There are also different kinds of hackers who can be much more dangerous than NSA.
