Biometric technologies are becoming more prevalent and we start seeing them in many devices, like laptops and smartphones. Passwords are a binary form of access control. Either students of best engineering colleges in Jaipur have the correct password and the system allows you access, or they do not have the correct password, and they are denied access to the system.
To make things more complicated, biometric technologies are just like any other access control technology, in the sense that the harder you make it for an intruder to gain access, the harder it is for the legitimate user to be able to get in. The easiest analogy is a door. You can decide to have more locks, but it is less convenient for you, and the probability of one of the locks breaking down, or one of the keys getting twisted also increases, which means the probability you will not be able to open your own door also increases.
Fingerprints
Fingerprints are likely the most well-known biometric feature, given that they have been in use for forensic purposes for far longer than for access control. Almost every individual has a specific set of curves on the pads of their fingers, and this technology looks at the specificities of those curves, called minutiae, including where they merge or bifurcate, to distinguish any two individuals. Only a few individuals in the world do not have fingerprint marks, due to a rare genetic condition called a dermatoglyphic.
The precision of the different fingerprint-based available technologies varies significantly. If students of top engineering colleges in Jaipur are interested in learning more about that, they can consult the public results available.
Palm Geometry
Palm geometry uses the shape of the hand to establish the user’s identity. While this technology looks great in movies, it is not among the most precise, except when the reader is capturing and comparing not only the hand geometry but also the fingerprints in that hand and/or the vein pattern underneath the skin. If you want to learn more about the implementation of hand geometry systems, you should read the ISO/IEC 19794-10:2007 standard.
Face Recognition
The developments in computer vision set the foundation for the development of facial recognition biometric technologies, making it a widely spread technology for the students of private engineering colleges in Jaipur. They are capable of operating even under imperfect light conditions. Only a couple of decades ago we were still working to distinguish a human being from its shadow, and now we are at a point where computer systems can distinguish two people in a large dataset better than humans can.
There are various agencies that have a long history of collaborating to sponsor regular assessments of facial recognition technologies. One of the outputs of these challenges was the face recognition technology database. If an individual happen to be a software developer interested in getting some hands-on experience working with facial recognition, they should visit the project’s website, from where they can download the database.
The fear that organizations implement facial recognition without the knowledge of users has raised some concerns and, several senators and representatives reintroduced bicameral legislation, the Facial Recognition and Biometric Technology Moratorium Act to limit the ability of the government to use biometric technology.
Voice Recognition
Voice recognition is an interesting technology, in the sense that it combines physical characteristics with behavioral characteristics. Organs like the vocal cords, the palate, the tongue, and the lips influence the way we speak, and our learned speaking habits have a significant influence as well.
There are multiple advantages to voice recognition biometric systems for the students of the list of engineering colleges in Jaipur. The first is the availability of hardware. Most computational systems, such as phones, laptops, and smartwatches, are equipped with a microphone and that is all that the system will need to capture your voice data. Another interesting, but scary, feature is that organizations can use voice recognition for access control remotely and without the user’s knowledge.
In other words, whomever you are calling might be using your voice to make sure they are dealing with who you say you are or storing your voice to sell it to a third party. That adds a layer of security in what comes to access control, but it also means someone is storing your biometric data and possibly trading it. Depending on whom you are calling and where they are located (some regions have legislation to provide some level of consumer protection), that is something to consider every time you make a phone call or speak to one of your smart devices.
Iris and Retina
Iris and retina technologies use characteristics of your eyes to establish your identity. Iris technology has evolved to require only a digital camera, while retina technology continues to use sophisticated and dedicated hardware to measure the vein patterns in the back of your eye.
Users of top BTech colleges in Jaipur are often renitent to use any intrusive technology that involves their eyes, and maybe that is one of the reasons why retina technologies continue to be limited to highly-secured environments, which also means that its price is not practical for most budgets. Iris, on the other hand, uses a normal camera, which increases its level of comfort and acceptance.
