Overview of Facial Recognition
In recent times, facial recognition technology has become more commonplace, thanks to its application in different fields, including security and law enforcement by identifying suspects. For example, Facebook uses facial recognition to identify users in photos uploaded to the platform.
In December 2020, Texas sued the facial recognition firm, Meta, that works with Facebook, over concerns about its facial recognition practices. So let’s take a closer look at facial recognition and how it is used on Facebook.
Definition of facial recognition
Facial recognition is a biometric technology that can be used to verify or recognize a person’s identity. It does this by measuring and analysing a person’s facial features, such as the shape of the eyes, eyebrows, nose and mouth. The collected biometric data is then compared to templates stored in a database – either on-site or ‘in the cloud’ – and returns results that inform the user whether or not it “recognizes” the face.
The use of facial recognition technology on social media sites such as Facebook is becoming increasingly commonplace. Facial recognition opt-in allows users to register their face with Facebook using their webcam or smartphone camera. Facebook then stores this data in its online databases, which can be accessed by third-party developers who create apps for users to interact with.
By using facial recognition opt-in feature, users can get personalised experiences when interacting with friends and family on the site, such as being automatically tagged in photos taken at events or matching previously uploaded photos to new ones posted by friends. Facial recognition also helps users keep their accounts safe from malicious access or potential intrusions from criminals by making it more difficult for hackers to break into an individual’s account.
How facial recognition works
Facial recognition is a computer-based technology used to accurately identify or verify a person based on the characteristics of their face. This technology works by scanning and mapping facial features from a photograph or video to create a digital ‘faceprint’ which can then be compared to other faceprints to decide if the two people are the same.
In technical terms, facial recognition is an automated process involving the measurement of distances between certain feature points of the face such as eyes, nose, and jaw line. When taking into account all possible permutations of points and distances on an individual’s face, it can be said that everyone’s ‘faceprint’ is unique.
Facebook utilises facial recognition software to recognise individuals in photos uploaded by its users via their social media platform. This allows Facebook to match faces across photos quickly and easily – even if they have been edited, cut up or cropped. In this way, Facebook can accurately tag people according to who they are while providing its users with an efficient way of managing all their photos.
Beyond this particular use case, facial recognition is increasingly being used in more advanced applications such as:
- Access control systems
- Automated payments systems
providing added security along with user experience benefits.
Texas Sues Meta Over Facebook’s Facial-Recognition Practices
Facial recognition technology is becoming increasingly popular on social media, and Facebook is no exception. The technology can be used to identify people in photos and videos, as well as to detect emotions, gender, age, and other characteristics.
Recently, Texas sued Facebook for its facial-recognition practices, which have caused much debate over the implications of using facial recognition technology on social media. In this article, we will take a look at the various uses of facial recognition on Facebook, and explore the implications of the Texas lawsuit.
How Facebook uses facial recognition
Facebook uses facial recognition technology to identify people in photos and videos when permitted by the user. This technology allows Facebook to suggest friends tag individuals in a photo, share photos or videos with the right audience, and create personalised experiences for the user.
For Facebook to utilize facial recognition, it must first collect a person’s biometric data, including details such as the size of eyes and nose and the shape of face and mouth. In addition to this data, Facebook inspects pixels in photos/videos and how they are distributed to differentiate one person from another. This information is collected only when you give explicit permission to do so.
Once your biometric information is collected, Facebook stores it in a digital template where it can be compared against other images on the platform or those uploaded by users. If a match is identified, Facebook notifies users that they have been tagged in photos/videos or suggested as someone similar on Pages or Groups. It also allows for friend suggestions. It also serves to help protect its users’ privacy by preventing someone from stealing their identity or using a photo without their consent.
Facebook’s use of facial recognition helps improve the user experience on the platform. Still, it can be turned on/off within Settings > Privacy > Face Recognition depending on individual preferences surrounding using this technology. Users should take into consideration concerns about their privacy when deciding whether or not to opt-in for this feature offered by Facebook.
Benefits of facial recognition on Facebook
Facial recognition on Facebook is a powerful security tool used to protect user accounts, provide varying levels of account access to other users and make tagging photos faster and easier.
As with many breakthrough technologies, facial recognition on Facebook can have both positive and negative effects, but the pros certainly outweigh the cons.
Some of the benefits of using facial recognition on Facebook include:
- Improving account security: Facial recognition can be used to detect unauthorised access attempts, making it more difficult for hackers to gain control of your account. It also helps prevent fraud by ensuring only authorised users can access your account.
- Easier authentication processes: Facial recognition utilises biometric data when you log in or make changes to your profile, so you no longer need to remember an array of passwords or PINs to use different services. Additionally, online conversations are generally more secure since users must use their facial data before being granted access.
- More accurate tagging: Whenever you upload a picture it will automatically detect and tag people’s faces – so long as they’ve allowed Face Recognition in their privacy settings. This makes it much quicker and easier than manually entering each person’s name during uploads and allows friends and family members not present at the event to be included in photo albums.
- Better photo sharing experiences: With real time linking capabilities, once a photo is tagged with a person’s face that user can then view –and potentially share — the same photo from wherever they may be located in the world with just one tap! This eliminates old school methods such as printing out physical copies for sharing via post or collecting multiple digital images from different devices for consolidating into an album.
Legal Issues Surrounding Facial Recognition
When it comes to facial recognition, there are a variety of legal issues that can arise. Recently, the US state of Texas sued Meta, a technology company, over its use of facial recognition tech in cooperation with Facebook. Meta was accused of unlawfully collecting and storing biometric information without the knowledge or consent of its customers.
In this article, we’ll look at other legal issues surrounding facial recognition:
Texas lawsuit against Facebook
In September of 2020, a lawsuit alleging that Facebook’s use of facial recognition violated the Biometric Information Privacy Act (BIPA) was filed in the Texas state court. The lawsuit claimed that Facebook had collected and stored individuals’ biometric information without their knowledge or consent, which is a violation of BIPA.
According to the complaint, Facebook had “secretly collected and used its users’ faceprints for years” and continued to store them indefinitely despite removing automatic face-tagging from photos.
The complaint also addresses alleged privacy violations related to facial recognition. It states that Facebook collected, stored, and used “data related to elements of an individual’s physical identity such as face geometry measurements derived from photographs and videos posted on the company’s platform by their peers or friends.” The complaint further alleges that the company did this without obtaining explicit consent from the individual whose data was being collected or whose faceprints were being used.
It further claims that Facebook has failed to provide users with clear instructions on how their faceprints can be secured or destroyed after they terminate their accounts with the social media giant. Moreover, it claims that Facebook has taken no steps whatsoever to ensure its storage and use of users’ data is compliant with BIPA standards.
Privacy concerns related to facial recognition
Privacy concerns related to facial recognition are increasing as the technology becomes more ubiquitous. Individuals may view the use of facial recognition as a form of surveillance, which can be seen as an infringement on privacy and civil liberties. Additionally, there may be potential bias, such as racial or gender discrimination, associated with using this technology, resulting in potential violations of human rights.
The use of facial recognition on social media sites such as Facebook raises several privacy-related issues. In particular, many people worry that the information gathered through facial recognition is being shared with companies for commercial purposes without their knowledge or consent. In addition, users’ personal information collected through this process can be used for identity theft and other criminal activities. There have also been reports of law enforcement agencies indiscriminately collecting biometric data from individuals with or without their consent and using it for investigative purposes.
Furthermore, privacy advocates are increasingly concerned about data being kept indefinitely despite users deleting accounts and photos from such sites as Facebook and Instagram. They argue that data accumulated through facial recognition technologies should not remain stored indefinitely unless it is necessary to do so for legitimate purposes; however there is currently no clear-cut regulation governing this practice in most countries.
Therefore, it is essential to ensure protections are put in place when developing new technologies involving facial recognition processing so that individuals’ right to privacy is protected both online and offline. This involves having safeguards to help limit biometric processing activities by governments, corporations and third-party entities while empowering people to exercise control over their personal information revealed through facial recognition processes on social media applications like Facebook.
Alternatives to Facial Recognition
Texas Sues Meta Over Facebook’s Facial-Recognition Practices has raised important questions about facial recognition technology and its potential applications. While facial recognition can be a powerful tool in certain contexts, it is not the only option for authenticating identity.
In this article, we will discuss some alternatives to facial recognition that can be used to authenticate identity:
Privacy-focused alternatives to facial recognition
Facebook has become increasingly aware of the privacy concerns that surround facial recognition technology, and has started to develop privacy-focused alternatives that still provide accurate authentication.
Some options include voice recognition, palm and fingerprint scanning, as well as photo-based analysis and behavioural biometrics. Each of these methods can be used to identify and authenticate individuals without the need for direct access to their face.
- Voice Recognition: This relatively new technology uses sound waves from a person’s speech patterns to create a unique signature associated with their identity. It is then used for authentication purposes by comparing the voice signature with pre-existing data records to verify a user’s identity.
- Palm & Fingerprint Scanning: Just like every thumbprint is unique, so are the plant veins on our hands and fingers. This form of recognition uses specialised scanners that take an image of both surfaces to match them against predetermined records stored in a database. This system is considered very secure since fingerprints are practically impossible to replicate or duplicate.
- Photo-Based Analysis: By accessing millions of photographs taken by users on Facebook, this method relies on algorithms specifically created for facial recognition to conduct comparison tests between different images to process the request accurately. Comparisons are performed between images and text – not just face shape – to enhance accuracy further and ensure there are no false matches or results when trying to authenticate an individual.
- Behavioural Biometrics: Utilising information regarding users’ click habits, scroll speed or cursor placement could make up behavioural biometrics, as these provide increased accuracy when taking into account contextual elements associated with their identities such as language or location preferences which can be used along traditional biometric data types for enhanced detection abilities.
Security and accuracy of alternatives
Facebook’s facial recognition feature works by using algorithms to match a face in someone else’s tagged photo with your profile picture to suggest adding a tag. This technology has improved dramatically over recent years and the accuracy of Facebook’s facial recognition is greatly enhanced by its artificial intelligence capabilities.
However, it is still wise to be aware of the security and accuracy of available alternatives. For instance, two-factor authentication – requiring two pieces of information to gain access to an account (even if one piece is your face) – as well as biometric authentication – Fingerprint or retina scan – can increase security and accuracy, while avoiding the potential ethical pitfalls associated with facial recognition technology. In addition, the false positives that may occur with facial recognition can be better avoided when combined with other methods such as voice or iris scanning.
In addition, tracking methods such as location-based services allow an app developer to track users within a certain area and enhance the security of their platform without compromising user privacy. Furthermore, solutions such as object identification technologies (e.g., image and sound recognition) could enable apps like Facebook to avoid using any type of explicit personal data for authentication purposes. Developers need to consider other forms of authentication and incorporate solutions that reduce false positives to protect user data from unauthorised access without compromising their privacy.
