Best Face Detection Software

Biometric is the technology used to identify and authenticate individuals quickly and reliably using biological characteristics.

There are various techniques for biometrics like fingerprint scanning, iris recognition, palm vein recognition, voice recognition, and face recognition. Whether they are operating solo or in combination, they make excellent tools in authenticating a person’s identity. Their adoption rate largely relies on user’s convenience and operation speed; considering these attributes face recognition is quite popular among the users.  It has emerged as a promising option for various organizations to identify individuals with high accuracy and minimize the risk of identity theft. Face recognition systems give a sense of security compared to traditional techniques like smart cards, PINs, plastic cards, passwords, tokens, keys, etc. Face detection is a computer-based technology that has its roots in Artificial Intelligence. 

The face identification is categorized into 4 categories,

1. Feature-based: The feature-based method is to locate faces by extracting the structural features of the face.
2. Appearance-based: The appearance-based approach uses statistical and machine learning techniques to learn the characteristics of face and non-face images from examples. 
3. Knowledge-based: The knowledge-based face detection method depends on the set of rules, based on human knowledge to detect the faces. 
4. Template matching: Template matching is a digital image processing method for finding small parts of an image that matches a template image. The template matching is used to detect the more accurate faces and neglect the others. The technique may involve edge detection, feature extraction, and object extraction. 

Once the face detection process is completed using any of the above methods, face recognition biometrics carries out the further identification and verification process.

Identity theft is like a treasure hunt for hackers; once they succeed in replicating identity, the damage they can bring is unaccountable. For instance, filing fraudulent income tax returns and applying for loans under the victim’s name. It can lead to financial loss and threatens a victim’s reputation. Despite all the precautionary measures taken by individuals, they were never far from the next incident of identity theft.  The traditional methods are powerless against such hackers. The only way to defend against these attacks is to use the uniquely detectable biological traits like face recognition or fingerprint scanning. Compared to other biometric systems, face recognition biometrics does not require physical contact with the device. It requires less processing time and helps to automate the authentication process.

Face recognition technology has immense potential to modernize the current identification system. And as per a few reports, the global biometric facial recognition market is estimated to surpass $12 billion by 2026. There is a rising demand for biometric surveillance systems among private and government institutes. Face recognition establishes a high level of security, with a minimum amount of time or effort. It is difficult to manipulate the facial features or steal the information. The face recognition system equipped with 3D facial recognition can accurately identify a number of different facial expressions and postures, regardless of the illumination level. The system can be easily deployed in a dark environment. 

Biometrics is just one area, but businesses are taking face recognition capabilities into new dimensions. The retail industry sees facial recognition as the ground-breaking technology in rendering personalized experience to the customer. Likewise, other sectors like law enforcement, logistics, immigration, and healthcare are equally excited about the face recognition applications in their respective fields.

Yes, compared to the existing identification process, the face recognition technology can bring remarkable improvements.  

The advanced technology within the face recognition tool is designed to compare and predict potential matches of faces regardless of their age, expression, and facial hair. The contactless facial recognition system speeds up the identification process and eliminates all the risk associated with existing identification processes.

• PIN lost or stolen: The most common person identification and verification method is using the PIN system (Personal Identification Number). The risk with such techniques is that the person can forget the PIN, or it can be stolen for misuse.
• Compromised passwords: The basic form of user authentication on the web is password authentication. If the individual doesn't have strong server security, someone can easily break into the database and read the passwords.
• Smartcards unauthorized access: Smartcards are protected by a two-factor authentication process that involves showing the card and then entering a password or PIN code. Again with PIN or password access, the risk of a security breach cannot be ignored.
• Hacking token-based authentication: The token-based authentication is the most secure form of authentication currently, as it is laced with two-factor authentication. But smartphone-based tokens sent as texts are riskier because they can be intercepted during transit.

Yes, there is software available for conducting facial identification.

Besides facial recognition, facial identification technology acts as the first step in many key applications like face tracking and face analysis. Face recognition tools like Face++ offer a range of features like face searching, face comparing, 3D face model reconstruction, including face detection to meet customer’s requirements. The user can use these features individually, or together as per the application requirement. In case if the users are not keen to develop the system from scratch, they can go for a ready-to-use face recognition system. 

There are also tools like Ever AI that give liberty to customize their face recognition system by using APIs.

Face recognition software is a technology capable of verifying or identifying a subject through an image, video, or any audiovisual element of his face. The advanced face recognition software even allows users to find people in real-time.

There are two main jobs of facial recognition systems:  

• The first is verification, where the input image is compared with the known identity. Unlocking mobile devices with facial identification is the best example where new input faces are compared with the registered face on the device. 
• The second is the identification where an input face is compared to a database of multiple face identities. It is mostly used for security and surveillance purposes. 

Although face recognition seems simple, identifying a particular face is actually a challenging task. .With the advancement of computer and artificial intelligence, the algorithm of face recognition has become smarter. It parses huge data in a few seconds and retrieves information with a high level of accuracy level.

Face recognition has a vast application in different sectors, and in various ways, it helps them to address their concerns.

Step 1: Face Detection

The camera will detect and recognize a face, either in a crowd or alone. The face detection process is a critical step as it detects and locates human faces in videos or images. The advanced face recognition system even allows capturing images in real-time. 

Step 2: Face Analysis

Once the face is detected, the photo of the face is captured and analyzed.  The face is analyzed on various nodal points such as spacing of the eyes, bridge of the nose, the shape of your cheekbones, the contour of the lips, ears, chin, etc.  Humans have 80 nodal points.

Step 3: Converting an image into code

In this step, the nodal points of the face are converted into a mathematical formula. The image is now converted into its digital form, also known as a faceprint. For each individual, the system generates a unique face print. 

Step 4: Face match

Face match verifies whether two faces belong to the same person. The face print of numerical code is compared against the database of other faceprints. If there is any match, the system will retrieve the image along with the name and address.
