The US government with assistance from major telecommunications and Internet companies has engaged in massive spying programs on millions of Americans. US President Barack Obama has defended the top-secret programs saying “they help us prevent terrorist attacks” despite their “modest encroachments on privacy.” Scope of phone and Internet surveillance has caused alarm among privacy advocates.
