How Does Facial Recognition Work?
Facial recognition is a way of recognizing a human face through technology. A facial recognition system uses biometrics to map facial features from a photograph or video. It compares the information with a database o f known faces to find a match. Facial recognition can help verify personal identity, but it also raises privacy issues.
The facial recognition market is expected to grow to $7.7 billion in 2022 from $4 bill ion in 2017. That’s because facial recognition has all kinds of commercial applications. It can be used for everything from surveillance to marketing. But that’s where it gets complicated. If privacy is important to you, you probably want some control over how your personal information — your data — is used. And here’s the thing: your “faceprint” is data.
How facial recognition works
You might be good at recognizing faces. You probably find it a cinch to identify the face of a family member, friend, or acquaintance. You’re familiar with their facial features — their eyes, nose, mouth — and how they come together. That’s how a facial recognition system works, but on a grand, algorithmic scale. Where you see a face, recognition technology sees data. That data can be stored and accessed. For instance, half of all American adults have their images stored in one or more facial-recognition databases that law enforcement agencies can search, according to a Georgetown University study.
So how does facial recognition work? Technologies vary, but here are the basic steps:
Step 1: A picture of your face is captured from a photo or video. Your face might appear alone or in a crowd. Your image may show you looking straight ahead or nearly in profile.
Step 2: Facial recognition software reads the geometry of your face. Key factors include the distance between your eyes and the distance from forehead to chin. The software identifies facial landmarks — one system identifies 68 of them — that are key to distinguishing your face. The result: your facial signature.
Step 3: Your facial signature — a mathematical formula — is compared to a database of known faces. And consider this: at least 117 million Americans have images of their faces in one or more police databases. According to a May 2018 report, the FBI has had access to 412 million facial images for searches.
Step 4: A determination is made. Your face print may match that of an image in a facial recognition system database.
How can you find more protection against facial recognition systems?
Will hackers really want to steal your face? If your facial data can be used to commit fraud or turn a profit, the answer is yes. Add that to the list of cyber safety risks. A holistic cyber safety package is worth considering helping protect your online privacy and security. For instance, Norton Security is designed to help protect your computer, laptop, and mobile devices against viruses, ransom ware, and cybercriminals.
Still, facial recognition represents a challenge to your privacy. After all, there are few rules governing its use. In the meantime, maybe those anti-facial-recognition glasses won’t look so bad.

ACCORDING TO NUTRITIONISTS
These Are the 5 Ingredients Your Multivitamin Should Have.
1. Vitamin D
Vitamin D helps our bodies absorb calcium, which is important for bone health. Not getting enough of this vitamin can increase your chances of bone and back pain and bone and hair loss.
While you technically should be able to get your daily vitamin D by being in the sunlight for 15 minutes, the reality is that over 47 percent of people don’t get it. 10 Living in wintery locations with little sunlight, working an office 9 to 5 life, and applying sunscreen (which blocks vitamin 13 synthesis) makes getting vitamin D hard. This vitamin is also hard to come by in food, 13 which is why Taub-Dix says to look for this ingredient in your Multifoods with vitamin D fatty fish, egg yolks and fortified foods like milk, juice, and cereal
Magnesium is an essential nutrient, which means that we must get it from food or supplements. Lerman notes that magnesium is best known for being important to our bone health and energy production. However, magnesium may have more benefits than that She adds that this mineral can also calm our nervous system and reduce stress after 90 days, cam, sleep problems, as suggested by an older study on mice, regulate muscle and nerve function, balance blood sugar levels and make protein, bone, and even DNA
But a lot of people are magnesium deficient because they aren’t eating the right foods, not because they need supplements. Try eating more pumpkin, spinach, artichoke, soybeans, beans, tofu, brown rice, or nuts (especially Brazil nuts) before jumping to supplements for solutions.
Over 40 percent of the U.S. population doesn’t get enough calcium from their diet. This means those people aren’t getting the mineral they need for strong bones and teeth. Women in particular start losing bone density earlier, and getting enough calcium from the start is the best nutritional defense against this loss. Foods with calcium fortified cereals, milk, cheese, and yogurt, salty fish, broccoli and kale, nuts and nut butters AND beans and lentils
“Zinc tends to be low in older people and anyone under a lot of stress,” says Lerman. Which, (hello!) is basically everyone. And it makes sense. Zinc supports our immune system and helps our body use carbohydrates, protein, and fat for energy. It also aids in wound healing. Foods with zinc, oysters, grass-fed beef, pumpkin seeds, spinach, organ meats, tahini, sardines, brown rice, wheat germ and tempeh The average American diet isn’t rich in foods that offer zinc, and the body can’t store zinc, which is why Lerman recommends your daily supplements highlight this ingredient.
“Iron should be in your multivitamin, but not everyone needs the same amount of iron,” Lerman advises. Some of the benefits of iron include: increased energy, better brain function and healthy red blood cells
Those who eat red meats typically get enough iron, but certain circumstances like having your menstrual cycle, going through puberty, and being pregnant may increase the amount of iron you need. This is because iron is essential during times of rapid growth and development. Vegetarians and vegans may also want to make sure their multivitamin has iron, especially if they’re not supplementing meat with other iron-rich foods.
