TOR is a software tool designed to enhance the privacy and security of your online activities. The TOR browser protects your identity and your search queries from various types of Internet surveillance. It is also useful when used to circumvent the electronic restrictions.
TOR protects your anonymity by transferring your communications through a distributed relay network operated by volunteers from around the world. The TOR browser conceals the pages you visit and thereby protects you against potential observers, and also hides your geographical location.
