Facial recognition is the technology that recognizes the face of a particular person. It uses biometry to compare personal facial characteristics with the information previously stored in its databases.
It is simple to accomplish since everybody’s facial structure is unique. The demand for face recognition, particularly in the USA, has taken an upward trend. The steps below demonstrate how facial recognition works.
• Detecting the face
The camera searches and locates the faces of one or more people within the camera angle. When a person has a straight look at the camera, the front face area is better defined. However, some technical changes have been made to allow the camera to function even if a person faces away.
• Face analysis
This step involves the capture and examination of the face. It distinguishes distinctive features and nodal points, including the outline of the jawline and the length between the eyes. For most face recognition systems, 2D images are more straightforward in giving matches than 3D ones, as most photographs in their databases are in the 2D model.
• Finding the face prints/facial signatures
Here, your face analysis follows a mathematical pattern. The facial features become numbers in a code known as the faceprint. Every individual has a unique facial print like the fingerprint pattern.
• Matching the faceprints
Your numerical facial code corresponds to other facial copies in a database. Databases contain images with IDs that can be used for comparison purposes. The Federal Bureau of Investigation agencies can access more than six hundred million photographs and databases. Facebook is yet another database that is accessible to many agencies. The technology identifies and matches the exact features of a particular database.
Advantages and disadvantages of facial recognition technology
Like other security technologies, facial recognition has both pros and cons, which had ignited various facial recognition legal battles. Some people endorse the face scanning technology while a significant number of others despise it. Below are some of the advantages and disadvantages.
One of the top benefits of face recognition is improved safety. The technology limits unauthorized access to user data as encrypted data are accessible only to the designated person. The system also helps locate missing people and identify suspects in different agencies like the police and investigating departments.
2.The smooth and quick integration process
Since touching is unnecessary, facial recognition is faster as it uses an automatic scanner to allow access. The integrable facial recognition software also functions relatively well with the latest security applications used by businesses. Additionally, you can also easily program it to communicate with the other software systems of a company.
3D facial recognition, together with infrared technology, has enhanced the reliability of facial recognition. It is hard to penetrate any system or device that employs the technology. Thus, there is a higher precision rate in facial recognition technology.
Different governments and security services use facial scanners to enforce the law. Their actions may occasionally violate the privacy of innocent people.
For example, recent protests in Moscow have encouraged people to apply some paint on their faces to avoid any prying eyes. National and international organizations, however, continue to use the technology to uphold safety.
2. Personal facial changes pose an effect
The faces of people continuously change over time, hindering facial recognition technology’s results. The technology is vulnerable to small changes. Face scanning technology cannot check one’s identity when there are some minor changes in the face. Therefore, companies developing facial recognition technology need to update its functionality to solve such issues.
3. Cameras need many surveillance angles
The effects can only be achieved from different camera angles. Faces can not be fully identified or interpreted without these angles. Obstructions like sunglasses may also pose a problem during the examination. Therefore, cameras must cover all aspects to avoid this.
Over the years, face recognition technology has made considerable progress. Today, computers can automatically verify identity information for individual purchases, access to buildings, surveillance, and security operations. Some people oppose it, as it is perceived as a way to violate their privacy.
