Face Detecting Technology
Technology
Facial recognition analyzes the characteristics of a person's face images input through a digital video camera. It measures the overall facial structure, including distances between eyes, nose, mouth, and jaw edges. These measurements are retained in a database and used as a comparison when a user stands before the camera. This biometric has been widely, and perhaps wildly, touted as a fantastic system for recognizing potential threats (whether terrorist, scam artist, or known criminal) but so far has not seen wide acceptance in high-level usage. It is projected that biometric facial recognition technology will soon overtake fingerprint biometrics as the most popular form of user authentication.
What is face recognition technology:
Like all biometrics solutions, face recognition technology measures and matches the unique characteristics for the purposes of identification or authentication. Often leveraging a digital or connected camera, facial recognition software can detect faces in images, quantify their features, and then match them against stored templates in a database.
Face recognition technology is the least intrusive and fastest biometric technology. It works with the most obvious individual identifier – the human face.
Instead of requiring people to place their hand on a reader(a process not acceptable in some cultures as well as being a source of illness transfer) or precisely position their eye in front of a scanner, face recognition systems unobtrusively take pictures of people's faces as they enter a defined area. There is no intrusion or delay, and in most cases the subjects are entirely unaware of the process. They do not feel "under surveillance" or that their privacy has been invaded.
Samsung face recognition technology :
Samsung was the first to pack advanced facial recognition technologies into a top-tier flagship with iris scanning technology inside the ill fated Galaxy Note 7. The technology stuck around inside the Galaxy S8 and new Note 8, which forms part of Samsung’s security suite alongside a broader face recognition system and fingerprint options.
Samsung’s iris scanning technology works by identifying the patterns in your irises. Just like fingerprints, these are unique to each person, making them very difficult to replicate. To do this, Samsung’s latest flagships are equipped with an infrared diode that illuminates your eyes regardless of the surrounding lighting conditions. This light wavelength can’t be detected by a regular front facing cameras, so a special infrared narrow focus camera then captures the detailed iris information. This image is then stored and processed locally on device, nothing is send via the internet.
Apple Face recognition technology :
Apple unveiled its new Face ID technology as part of its iPhone X launch. Unlike Samsung’s technology, Face ID is designed to map out a user’s entire face in a highly secure manner. It doesn’t just rely on the phone’s familiar front facing camera, there are actually lots of sensors crammed onto that strip at the top.
The iPhone X comes equipped with an array of sensors designed to capture details of your face. For starters, it uses an infrared flood light to illuminate your face, which will work regardless of your surrounding lighting conditions as it’s outside of the visible spectrum. A secondary 30,000-point infrared laser matrix is then beamed out, which reflects off the flood light. Rather than snapping a picture of this infrared light, a special infrared camera detects subtle changes in the matrix point reflections as your face makes minute movements, which allows the camera to capture very accurate 3D depth data.
