In today’s digital age using biometric technology has made authentication a trustworthy method. With leaps in technology, biometric authentication has become significantly more secure than traditional passwords. It is also faster and convenient for everyone involved. Biometrics simply involve physical, and sometimes behavioral characteristics to create unique identifiers to verify and authenticate individuals.
As part of the digital process, it can also be seamlessly integrated with other aspects of the process in question. Whether applied in workplaces, top security installations, or simply examinations, biometrics provide the authorities with the best way to stay secure. Biometric security has also been used as an effective tool in keeping track of people in a closed space. As such, it’s an effective tool for attendance in examinations and workplaces. These services can be easily availed by the biometric service provider who provide end-to-end solutions and support.
Varieties in Biometric Systems
Biometric by definition deals with the physical characteristics of a human being. But due to advancement in sciences and technologies, it currently also includes the analysis of behavioral patterns. There are numerous kinds of biometric means to authenticate however, and some are listed as follows:
Fingerprints have a long history of being used as an identifier. Whether for legal reasons or forensic purposes, fingerprints have been a surefire way to prove a person’s identity. Nowadays however fingerprint scanning as an option can be found even on smartphones to secure onboard data. It is also the most basic form of biometric measure that’s used for security, and is used by approximately 57% of companies around the world.
Biometric face recognition system methods are used worldwide to run facial characteristics through an algorithm using artificial intelligence. Since human facial characteristics don’t usually change throughout human age, it can serve as a credible and accurate security measure. For a long term security measure it is not however the best option, since extensive surgery or because of age, facial characteristics of a person may change significantly. As a ranged security measure however, it works better than many others to make sure that unauthorised individuals are tracked from a distance.
Other than the unique patterns of the human fingerprint and facial characteristics, there exists another unique identifier. The iris portion of human eyes are quite detailed when magnified. As such, using high contrast images and infrared algorithms can create images that are unique to each individual. This biometric measure also sees application in exam monitoring services to keep exam malpractices away. It is a great way to identify people from a distance and trigger actions accordingly. It could either open the door for authorised individuals, or help catch identified and unauthorised individuals. Iris scanning is no longer in the realm of science fiction. Due to advancements in technology, iris scanning is now a reality.
Voice authentication matches pre-recorded voice, and calculates data like timbre, pitch and variance to authenticate the right people. Currently, other than fingerprint and facial recognition, this biometric method can be found in smartphones and other computer devices as well. While this is not yet at its best, and can be easily spoofed, further improvements will change it for the better.
While not as secure as live facial and iris scanning, ID card photographs are still used to identify and verify individuals in workplaces.
Signing names and other forms of signatures have been in use for decades. This method is still used by many in their everyday lives and still see widespread use at retail checkouts and banks. Digital signature scanners make sure a digital record exists of this traditional means of authenticating people. Obviously it is not accurate, but signatures still carry a legal value.
Genetic identification offers a unique way into identifying and authenticating individuals. Due to the matter of ethics however only government agencies have permission to access such information. It is mostly used in forensics by law enforcements to identify suspects.
Biometric measures aren’t limited to just physical characteristics. Psychological progresses have identified ways in which behavior can be used to identify humans from computer programs. This option of identification measure is generally used in tandem with physical based biometric measures because of inherently lower reliability. However with the progress in technology, these behavioral identifiers will become more prominent and can be used on their own.
The advantage behavioral patterns have over physical identifiers, is the lack of a limitation. Nowadays this identification option helps differentiate between humans and bots. This method is helpful in separating spam created by bots and actual human interaction. These predictions can block even brute-force attacks due to behavioral understanding of humans.
Behavioral identifiers are a newer approach and are typically being used in conjunction with another method because of lower reliability. However, as technology improves, these behavioral identifiers may increase in prominence. Unlike physical identifiers, the only limits to behavioral identifiers is the human imagination. Here are some of the common uses of behavioral identifiers:
While all individuals have a different way of typing. It includes speed of typing, the amount of time spent moving from word to word, and the impact on keyboards as factors. Utilising these metrics artificial intelligence algorithms can identify human and bot actions.
The way that someone walks is unique to every individual and is used to understand their intent during their movement. For instance, when someone is being erratic with their movement, they might cause a security concern for particularly sensitive locations.
Computer Navigation Patterns
Mouse and finger movements on trackpads are different from ones directed by scripts and bots. Identifying these movement patterns is important in finding if an action is being triggered by bots or humans instead. This could help isolate systems that’s hacked or infected by computer viruses.
Progress made in the field of technology and programming has brought these security measures from the pages of science fiction to reality. It is only thanks to these innovations that the world knows better security. In a time where digital technology has been used for malpractices and to create breaches into data security, these forms of security is a necessity. In whichever form biometrics exist right now, they are here to stay.
