Face detection what is

According to this consumer report , car companies are experimenting with facial recognition to replace car keys. Facial recognition can help gambling companies protect their customers to a higher degree. Monitoring those entering and moving around gambling areas is difficult for human staff, especially in large crowded spaces such as casinos. Facial recognition technology enables companies to identify those who are registered as gambling addicts and keep s a record of their play so staff can advise when it is time to stop.

Casinos can face hefty fines if gamblers on voluntary exclusion lists are caught gambling. Technology companies that provide facial recognition technology include:. Aside from unlocking your smartphone, facial recognition brings other benefits:. On a governmental level, facial recognition can help to identify terrorists or other criminals. On a personal level, facial recognition can be used as a security tool for locking personal devices and for personal surveillance cameras.

Face recognition makes it easier to track down burglars, thieves, and trespassers. The sole knowledge of the presence of a face recognition system can serve as a deterrence, especially to petty crime.

Aside from physical security, there are benefits to cybersecurity as well. Companies can use face recognition technology as a substitute for passwords to access computers. In theory, the technology cannot be hacked as there is nothing to steal or change, as is the case with a password. Public concern over unjustified stops and searches is a source of controversy for the police — facial recognition technology could improve the process.

By singling out suspects among crowds through an automated rather than human process, face recognition technology could help reduce potential bias and decrease stops and searches on law-abiding citizens.

As the technology becomes more widespread, customers will be able to pay in stores using their face, rather than pulling out their credit cards or cash. This could save time in checkout lines. Since there is no contact required for facial recognition as there is with fingerprinting or other security measures — useful in the post-COVID world — facial recognition offers a quick, automatic, and seamless verification experience.

The process of recognizing a face takes only a second, which has benefits for the companies that use facial recognition. In an era of cyber-attacks and advanced hacking tools, companies need both secure and fast technologies. Most facial recognition solutions are compatible with most security software. In fact, it is easily integrated. This limits the amount of additional investment required to implement it. While some people do not mind being filmed in public and do not object to the use of facial recognition where there is a clear benefit or rationale, the technology can inspire intense reactions from others.

Some of the disadvantages or concerns include:. Some worry that the use of facial recognition along with ubiquitous video cameras, artificial intelligence, and data analytics creates the potential for mass surveillance, which could restrict individual freedom. While facial recognition technology allows governments to track down criminals, it could also allow them to track down ordinary and innocent people at any time.

Facial recognition data is not free from error, which could lead to people being implicated for crimes they have not committed. For example, a slight change in camera angle or a change in appearance, such as a new hairstyle, could lead to error. The question of ethics and privacy is the most contentious one. Governments have been known to store several citizens' pictures without their consent.

In , the European Commission said it was considering a ban on facial recognition technology in public spaces for up to five years , to allow time to work out a regulatory framework to prevent privacy and ethical abuses.

Such large data sets require robust data storage. Small and medium-sized companies may not have sufficient resources to store the required data. While biometric data is generally considered one of the most reliable authentication methods, it also carries significant risk.

Around the world, biometric information is being captured, stored, and analyzed in increasing quantities, often by organizations and governments, with a mixed record on cybersecurity. A question increasingly being asked is, how safe is the infrastructure that holds and processes all this data?

As facial recognition software is still in its relative infancy, the laws governing this area are evolving and sometimes non-existent. Regular citizens whose information is compromised have relatively few legal avenues to pursue. Cybercriminals often elude the authorities or are sentenced years after the fact, while their victims receive no compensation and are left to fend for themselves. As the use of facial recognition becomes more widespread, the scope for hackers to steal your facial data to commit fraud — increases.

A comprehensive cybersecurity package is an essential part of protecting your online privacy and security. We recommend Kaspersky Security Cloud which provides protection for all your devices and includes antivirus, anti-ransomware, mobile security, password management, VPN, and parental controls.

Biometric technology offers very compelling security solutions. Despite the risks, the systems are convenient and hard to duplicate.

These systems will continue to develop in the future — the challenge will be to maximize their benefits while minimizing their risks. We use cookies to make your experience of our websites better.

How does facial recognition work? Facial technology systems can vary, but in general, they tend to operate as follows: Step 1: Face detection The camera detects and locates the image of a face, either alone or in a crowd. However, this kind of method comes with one huge challenge: it is very difficult to build an appropriate rules set. If the rules are too general, there may be many false positives — and, conversely, if the rules are too detailed, the system could generate many false negatives.

Summary: A face is determined based on whether it meets a set of rules made by a human. With a template matching algorithm, parameterized or pre-defined templates are used to locate or detect faces — the system measures the correlation between the input photos and the templates. For instance, the template may show that a human face is divided into nose, mouth, eyes, and face contour regions. Also, a facial model could be comprised of just edges and use the edge detection method — implementation of this approach is easy, but it is insufficient for face detection.

Summary: Images are compared to standard face patterns that have been previously stored. In general, this method relies on machine learning and statistical analysis to determine relevant facial characteristics. An appearance-based approach is generally considered to be stronger than the previously mentioned methods. When the aforementioned strategies are combined, they can create a comprehensive face detection approach.

Researchers Ashu Kumar, Amandeep Kaur, and Munish Kumar published a review of face detection techniques , which included a detailed explanation of the challenges that facial detection faces. To sum up their findings, the challenges in face detection include:. As we mentioned earlier, deep learning is a subset of machine learning in which large neural networks process huge amounts of data and make complex predictions.

So how does deep learning factor into face detection? Well, multiple deep learning methods have been developed specifically for facial detection. This approach is popular because it achieved cutting-edge results for the time on a variety of benchmark datasets — plus, it is able to use landmark detection to recognize the eyes, mouth, and other facial features.

The image is first rescaled to different sizes or an image period. P-Net proposes facial regions, R-Net filters the bounding boxes, and O-Net proposes facial landmarks. Face detection is the initial step in face analysis, face tracking, and, most importantly, face recognition. The latter industry is growing by leaps and bounds, and is applied to device unlocking, banking, hospitality, law enforcement, building security, and more.

Face detection is necessary for facial recognition algorithms to know which parts of an image must be used to generate faceprints. Facial recognition is merely one application of face detection.

The former is used for biometric verification and device unlocking, whereas the latter can also be applied to facial analysis and tracking.

While face detection systems can be powerful, they are by no means foolproof, as demonstrated by our list of challenges. Intuiface Grassfish Broadsign. Everything About.

Face Detection. What is Face Detection? How does Face Detection work? Once trained, the algorithms are able to answer two questions in response to input in the form of an image: Are there any faces in this image? If yes, where are they? Why is Face Detection important? How can you use Face Detection? Aside from using face detection in conjunction with the technologies described above, you can use face detection to: Count the number of people entering a retail store or looking at a digital display Identify which areas of an image to blur to ensure privacy see Face Blur.
