In the digital age, security procedures have indeed undergone a dramatic evolutionary phase. Security technologies are now well-structured to counter hacker threats or malicious code attacks in a timely manner by equipping them with better detection strategies. This leads to a discussion on the topic of “ethical hacking” (discussed later in this article). Additionally, we will examine different biometric authentication methods in detail, including face, fingerprint, and iris recognition methods. “Biometrics” is a Greek word with two parts: “bio” for life and “metric” for measurement. In computer science, biometrics is defined as a method of verifying an entity based on a person’s physical or behavioral characteristics.

What Is Biometric Authentication Method In Security ?

Biometric authentication proves a method of verifying a user’s entity. Biometric authentication is basically a pattern recognition system used to authenticate or entify users based on their unique physical characteristics. Biometric authentication is the process of ensuring that the person is who they say they are. Authentication can be achieved in a number of ways, such as through something a person knows (password authentication), something a person has (keys), and something a person has (fingerprints, footprints, facial recognition). Unique entifiers of indivuals, such as fingerprints, footprints, and facial recognition, can be used to prevent unauthorized access to systems by using automated biometric verification processes or by verifying an indivual’s unique entifier or physical characteristics for authentication.​​​.

What Are The Biometric Authentication Techniques ?

Various biometric authentication technologies are currently available, but in addition to these, the most common ones currently commercially are: fingerprint, facial recognition, finger geometry, hand geometry, palm print, iris pattern, and retina pattern.

Fingerprint Technology :

Fingerprinting is the oldest of all biometric programs. Fingerprints are already used in many countries such as India and China to correctly entify indivuals before entering systems (companies, organizations or even logging into computer systems). Optical fingerprint readers are the most commonly used fingerprint readers today. It is based on the change in reflectivity of the finger nipple line touching the reader surface. All optical fingerprint readers have a light source, a light sensor, and a special reflective surface that changes reflection based on pressure. Some readers are also equipped with processing and memory chips. The fingerprint bitmap is obtained with an optical fingerprint reader, as shown in the image above.

Face Recognition Techniques :

Face recognition techniques in computer science are used to automatically entify or verify people based on their digital images or using video frames present in databases. This technique can be valated by taking an example of a video frame or digital image and comparing it to an example in a database. A good quality pixel camera with sufficient resolution to acquire the image or any scanned image can be used as input to facial recognition technology. Again, depending on the camera or scanner we get more accurate results. Under what conditions the photo was taken, whether the lighting conditions are good, and in poor lighting conditions, indivual features may not be clearly visible. Face recognition systems generally only use grayscale information. Face recognition technology develops in the two fields of face measurement and eigenface. Face metrology techniques depend on specific features of the face, ie. H. The position of the eyes, nose and mouth also depends on the distance between all these features. A normal face image is called a canonical image, and its face metrics are calculated and stored in a face template. The typical size for storing such a template is between 3 and 5 Kb, but there are also systems with very small template sizes, ie. H. 96-byte point) eigenface methods are based on ifying faces according to the degree of eigenfaces, with a fixed set of 100 to 150 eigenfaces. This method is similar to the police method of creating portraits, but the image processing here is automated and based on real images. There are various face recognition software that can assign each face a match with each of the 150 main eigenfaces, probably only the 40-42 template eigenfaces with the highest fit are required with 99% accuracy Rebuild the face.

IRIS Recognition :

IRIS recognition is a unique authentication technique that uses the iris of the eye (the colored area around the pupil). In this technique, the iris pattern is obtained on a video-based acquisition system. Iris recognition is consered the best example of biometric authentication because the iris is protected by the eyel, cornea, and aqueous humor, which, unlike fingerprint recognition, minimizes damage. The process of iris recognition includes the following steps: 1. Taking a picture: You can take a picture with a standard camera using visible and infrared light. The person can do it manually, but make sure the iris should be in focus and the length between the camera and the iris should be between 6 and 12 inches. In the case of an automated system, the camera automatically locates the face and iris focus and adjusts the length between three and a half inches to one meter. 2. Define the iris position and optimize the image: If the iris is sharp, the iris recognition system will only entify the image with the best sharpness and clarity. The goal of the IRIS recognition system is to entify areas suitable for feature extraction and to remove areas covered by eyels, dark shadows, and reflective areas. 3. Storing and comparing images: Once the images are stored in a database (called an iris code 512-byte record), the process of segmenting, filtering, and mapping iris segments into hundreds of vectors occurs. The comparison software takes two iris codes and calculates the Hamming distance from the different digits. If the calculated Hamming distance value is within the range, that is H. 0 – 1, representing the same iris code, this result is again compared to the safety threshold to make the final decision. Iris recognition is the fastest recognition of all biometric systems.

What Is Ethical Hacking ?

In more common terms, ethical hacking can be defined as finding or trying out system security holes and looking for loopholes that could be exploited by malicious hackers. The IT security industry uses the term “ethical hacker” to describe a hacker whose intent is to attack a network or other security system in order to test the network and discover potential threats on a computer or network on behalf of its owner. A person who maliciously or criminally breaks into a computer network to test or evaluate its security vulnerabilities is called an ethical hacker (whose goal is to maliciously break into a system for personal gain). Ethical hackers can be expressed in many other words and in different ways – like white hat hackers, they’re not actually bad hackers or black hat hackers. The goal of a white hat hacker is to secure and secure an FT system or network, while a black hat hacker is someone who performs unethical hacking. These are criminal hackers or crackers who use their skills and knowledge for illegal or malicious purposes. The term “Certified Ethical Hacker” (CEH) is a qualification obtained when assessing the security of computer systems, may be employed by an organization, and may be a trusted indivual (on a computer) who performs hacking or attempts to penetrate a network and/or uses Computer systems with the same methods and techniques as hackers.

Why Do We Need Ethical Hacking ?

In modern times, increasing cybercrime is a big problem, so ethical hackers offer a more comprehensive solution to protect and prevent such crimes and attacks. Also, it only proves security for the network. Ethical Hacking has also introduced a term known as “reverse engineering” – usually the term reverse engineering refers to finding bugs in software developed commercially for multinational companies. Finding bugs through reverse engineering is called a “bug bounty”. This solution is best for testing any program from backend and frontend.

Differences between Ethical Hacker and Hacker ?

An ethical hacker is a white hat person who looks to networking and security to find any bugs not found during the testing phase of a given project. Ethical hackers are licensed and work at the request of the project owner. Ethical hackers are more capable than traditional black hat hackers because all resources are available to white hat hackers. Hackers are traditionally criminals who can break into and disrupt networks without the owner’s authorization. These hackers are also known as black hat hackers. Black hat hackers aim to steal personal or confential information from a victim’s system. These people are not legitimate or friendly people.
