Self-portrait pupillary reflex reveals the address. How can a photo betray our personal privacy?

Whether you are a talented person or an ordinary person, the highest praise in the circle of friends is always a selfie, especially on holidays, through which you can feel the love of the world. When you enjoy the praise from various social networking sites, some risks come quietly.

You can use Google Maps to input the positioning system information of the picture. The current positioning system is very accurate. You can find out a lot of location information from a photo and find out where the photo was taken. Not long ago, a Japanese otaku did a great thing and found the home address of the star through the photo of the female idol. Then the boy found the female star's home address and harassed her.

With the rapid development of science and technology, the definition of high-pixel mobile phones is getting higher and higher. Girls who love beauty love to take photos by themselves, and each photo can basically see any details of the face. At the same time, you can also see the scene reflected in your eyes from your pupils, accidentally exposing your home address. As we all know, people in China have the habit of scissorhands when taking pictures. In fact, this action is also extremely risky. When taking photos with a camera, photos taken within the range of 1.5m can recover 100% fingerprints.

Andy, deputy director of Shanghai Information Security Industry Association, said at the Shanghai regional activity of 20 19 National Cyber Security Publicity Week that if the camera lens is close enough, Scissorhands photos can restore the fingerprint information of people in photos through photo enlargement technology and artificial intelligence enhancement technology. Remind everyone that when taking pictures in a circle of friends, you must be careful not to be careless.
