Biometric verification Homework help
What is biometric verification?
Biometric verification is any means by which a person can be uniquely identified by evaluating one or more distinguishing biological traits. These biological identifiers include fingerprints, hand and earlobe geometries, retina patterns, voice prints and written signatures. Fingerprints are the oldest type of biometric verification and they’ve been used since ancient times with clay seals. The digitization of information and databases made them more popular. New technologies have enabled almost instantaneous identification. At assignmentsguru we have a pool of experienced professional writers in the field of Biometric verification.

How does a biometric verification system work?
The authentication process for biometric data is relatively consistent from one biometric identifier to another. First, a copy of a person’s unique characteristic — for example, a voice print of a person wanting access to bank account information — is made and stored in a database. When the person returns to ask the bank a question about their account, ID verification is required For that part, a new voice print is captured and compared with one in the database. If they match, the person’s identity will be confirmed.
Cloud technology is often used to make biometric information more accessible and portable. Cloud-based systems enable agencies and organizations to perform biometric identification on any individual, regardless of their location.
Even though security vulnerabilities still persist with cloud computing, there are a lot of vendors providing more secure cloud serverscHowever, the attack surface in the cloud is larger because there are multiple tenants. Even with effective tenant controls, there is some risk in a multi-tenant cloud
Where biometric data is stored is important. If a database containing the identification records is compromised, the biometric system tied to the data would be vulnerable, too. A biometric verification system depends on the use of biological characteristics that can’t be changed or replicated. If the data tied to the system isn’t secured, it could be extracted, deleted or manipulated, undermining the reliability of the system.
Where is biometric verification used?
Biometric verification is used to identify people in all sorts of settings, including the following:
- Financial institutions are using voice recognition and other biometrics to identify phone callers..
- Healthcare providers are finding biometrics to be a reliable way to identify patients.
- Law enforcement agencies use fingerprints, facial recognition, iris scans and other types of biometric ID to track people entering and returning to the criminal justice system.
- Other government entities are looking into using biometric identifiers in passports and for voter registration purposes..
Types of biometric verification
There are several ways to accurately and securely verify a person’s identity using biometrics. The following is a list of the more common types of verification systems and the technologies they use to facilitate accurate and reliable user authentication.
Fingerprint scanners, or fingerprints as they’re more commonly called, provide a quick and reliable way to identify the user and use devices such as smartphones. These scanners have been around for quite some time now because of their scope & simplicity.
The reliability of this technology comes from its lack of replicability. It is not easy to fool a fingerprint scanner, even with technology. Fingerprints are also harder to fake than passwords or other unique personal identifiers. For example, in 2016 Sprint’s phone users were targeted by hackers who gained access to the accounts of 200,000 users after bypassing the fingerprint locks of just 46 people using sophisticated methods.
Facial recognition maps features on a person’s face. This is one of the most common types of verification methods because it has the benefit of being able to match up data points in an individual’s facial features.
Apple has developed Face ID which scans and verifies the device of an individual. They are also able to create a depth map & infrared image of a face in order to get more accurate information. Using bionic chips, such as the A11 and A12X Bionic, Face ID transforms the depth map and the infrared image into an easily stored mathematical representation of facial characteristics.
Though facial recognition technology is convenient and effective, there are some weaknesses. During the 2019 Black Hat conference, researchers demonstrated how Apple Face ID could be hacked in less than 120 seconds. The researchers took advantage of two security vulnerabilities in Apple’s biometric verification process. The first was the accuracy of Face ID’s liveness detection. Liveness detection is the facial recognition technology’s ability to determine if a user is alive or awake to prevent the use of masks, fake heads, or sleeping or unconscious users.
The second vulnerability was the iPhone’s inability to accurately map the eye area of users wearing glasses. The researchers created glasses with opaque lenses and faux irises, placed them on a sleeping user and unlocked their device without their permission. While this approach isn’t easy to replicate, it highlights the limitations of facial recognition.
In addition to smartphones, facial recognition is used as physical security in buildings to limit access to authorized individuals. As this technology becomes more affordable, its range of applications will increase.
Iris and retina pattern recognition
Iris and retina patterns are unique and diverse, and so they make reliable biometric identifiers. An iris scanner can collect as many as 200 unique biometric features. Given the strength of security and reliability of this form of identification, banks are using iris and retina pattern authentication methods to verify ATM (automated teller machine) users. The U.S. military has used iris scanning technology for more than 15 years to screen people entering military facilities in Iraq and Afghanistan and to identify and track detainees.
Voice waveform recognition
Physical features aren’t the only form of biometric authentication. A person’s voice can be a unique biometric indicator that organizations can utilize to authenticate users. Many financial institutions, for example, use voice recognition to identify clients over the phone. Phone calls are a common phishing technique used by threat actors to extract assets or information. Voice recognition can help reduce the success rate of criminals attempting to pose as known individuals.
Nuance Communications Gatekeeper uses voice biometrics technology to confirm the age of callers. It was designed to prioritize elderly customers during the COVID-19 pandemic.
Voice waveform recognition has limitations, however. A threat actor could record the voice of a user and replay it for the voice recognition technology. Despite this, it is still an effective way to segment customers. Voice-based technologies, like Siri, Google Assistant and Alexa, all use some form of voice biometrics. For example, Google has users repeat a series of phrases to be able to recognize their voices when they speak certain commands.
Earlobe and hand geometry identification
Hand and earlobe geometry are both used to ID individuals measuring finger length and the distance between various parts of the hand. However, hand geometry changes with age and requires regular database updates. Earlobe geometry is one of the few biometrics that does not change with age.
DNA (deoxyribonucleic acid) matching
Genetic material from an individual can be compared with existing DNA databases to verify a person’s identity. This method is commonly used in criminal investigations for forensic purposes. If you are concerned about identity fraud, the most accurate option is to compare their DNA with that of the evidence. It is an invasive procedure but can be worth it if you need proof of someone’s identity.
Scans of finger veins are used to verify individuals’ identity. The vascular pattern in a person’s finger can be compared to data that was previously obtained to make an identification.
Signatures are one of the least reliable biometric verification methods. Signatures are vulnerable to replication and manipulation, but they are useful as an additional layer of authentication.
The inconclusive nature of the “Zodiac Killer” case mostly came from the subjectivity and inaccuracy of handwriting analysis. The self-proclaimed “Zodiac Killer” sent letters to the FBI throughout the 1960s, but those letters could not be used as definitive evidence due to human bias and other issues. These letters could never conclusively identify the killer because of the lack of handwriting analysis technology.
Signature analysis can identify instances of identity fraud where the signature attempt does not match existing records. Therefore, it exists more as a forensic tool than an immediate form of verification.
