WHAT IS TOR BROWSER?

What is TOR?

Tor is software that allows users to browse the Web anonymously. Developed by the Tor Project, a nonprofit organization that advocates for anonymity on the internet, Tor was originally called The Onion Router because it uses a technique called onion routing to conceal information about user activity

Is TOR is legal?

Tor to browse the Internet is not illegal. The download is free, and hiding your IP address and browsing history is not, in and of itself, illegal. However, many of those that use Tor use it specifically for anonymity because they are doing something illegal.

What is Tor Org?

Tor, also known as the Tor Project or the Onion Router, is an online anonymity network designed to conceal its user's identity and online activities. It does this by first encrypting the user's  communications, and then routing these communications through a network of relays located around the world

How TOR works?

Tor Browser obtains a list of Tor nodes or relays from the Tor directory server

Tor Browser picks a random path through Tor network to the destination server. All connections inside Tor network are encrypted. this example, the last connection is not-encrypted. The last connection would be encrypted if were visiting an https website.If at the later time, visits another server , Tor Browser selects a different random path.

INDIAN HACKER INVENTED SIXTH SENSE

Sixth Sense is a gesture-based wearable computer system developed at MIT Media Lab by Steve Mann in 1994 and 1997 (head worn gestural interface), and 1998 (neck worn version), and further developed by Pranav Mistry (also at MIT Media Lab), in 2009, both of whom developed both hardware and software for both head worn and neck worn versions of it. It comprises a head worn or neck-worn pendant that contains both a data projector and camera. Head worn versions were built at MIT Media Lab in 1997 (by Mann) that combined cameras and illumination systems for interactive photographic art, and also included gesture recognition (e.g. finger-tracking using colored tape on the fingers).    

WORKING

The Sixth Sense prototype is comprised of a pocket projector, a mirror and a camera. The hardware components are coupled in a pendant like mobile wearable device. Both the projector and the camera are connected to the mobile computing device in the user’s pocket. The projector projects visual information enabling surfaces, walls and physical objects around us to be used as interfaces; while the camera recognizes and tracks user's hand gestures and physical objects using computer-vision based techniques. The software program processes the video stream data captured by the camera and tracks the locations of the colored markers (visual tracking fiducials) at the tip of the user’s fingers using simple computer-vision techniques. The movements and arrangements of these fiducials are interpreted into gestures that act as interaction instructions for the projected application interfaces. The maximum number of tracked fingers is only constrained by the number of unique fiducials, thus Sixth Sense also supports multi-touch and multi-user interaction.  

The Sixth Sense prototype implements several applications that demonstrate the usefulness, viability and flexibility of the system. The map application lets the user navigate a map displayed on a nearby surface using hand gestures, similar to gestures supported by Multi-Touch based systems, letting the user zoom in, zoom out or pan using intuitive hand movements. The drawing application lets the user draw on any surface by tracking the fingertip movements of the user’s index finger. Sixth Sense also recognizes user’s freehand gestures (postures). For example, the Sixth Sense system implements a gestural camera that takes photos of the scene the user is looking at by detecting the ‘framing’ gesture. The user can stop by any surface or wall and flick through the photos he/she has taken. Sixth Sense also lets the user draw icons or symbols in the air using the movement of the index finger a

nd recognizes those symbols as interaction instructions. For example, drawing a magnifying glass symbol takes the user to the map application or drawing an ‘@’ symbol lets the user check his mail. The Sixth Sense system also augments physical objects the user is interacting with by projecting more information about these objects projected on them. For example, a newspaper can show live video news or dynamic information can be provided on a regular piece of paper. The gesture of drawing a circle on the user’s wrist projects an analog watch.
