In the process, I often hear the same question: can we authenticate with the application using biometrics, such as face or fingerprint recognition? There are several perspectives in this regard, but none of them are promising.
Although we live in the age of Big Data, we still cannot ensure accurate biometric authentication via backend services. The main reason simply comes down to the volume of data. The thing is, the commonplace username-password combo tends to be characters long, which is a negligible amount of data to transmit over the Internet. As opposed to this, a fingerprint scan of decent quality is quite a bit of information for the system to send. When facial recognition is in place, the volume gets even bigger.
Some people will argue that hashing could be the response to this challenge, because it allows you to transform any data entity into a shorter value of fixed length. Unfortunately, the hashing tactic brings us to another issue that will exhaust any super-productive system. In order to log in using a password, we need to reproduce this password accurately. In plain language, the hash is a string that you can derive from the password, but which cannot have the password derived from it.
This protects your sensitive data from being stolen and abused. Therefore, one of the fundamentals of hashing is to complicate the decoding routine. Even very similar passwords will have absolutely different hashes.
As you can see, the resulting strings are completely different even for nearly-identical input values.
When a user places their finger on the scanner, the slightest offset for a fraction of a millimeter, a change in pressure, skin damage and other circumstances always affect the resulting image. Consequently, the scans of the same finger or face will always be different. We have learned to recognize the key elements and perform the comparisons based on the presence and location of these elements. This type of search routine is aimed at finding elements that resemble each other approximately rather than exactly.
All of us have run into unfamiliar people who bear a striking resemblance to someone we know. There are ethnic groups with very few anthropological types, where the probability of a match is appreciable. When fuzzy string searching steps in, though, things look entirely different.
Speaking of authentication in the context of hundreds of millions of users, a fuzzy string searching system is likely to pick a person who resembles you on a photo more than you resemble yourself on that photo. This type of approach implies that you cannot change biometric characteristics like you can change a password — you have them since birth. Moreover, our biometric data is always available to an external observer.
We are constantly leaving our fingerprints, photos of our faces and DNA traces from our hair and nails. We are doing it permanently without even noticing it. Imagine facial recognition on a mobile device 15 years ago. In the age of the 0. Nowadays, the average cheap smartphone provides photo quality hundreds of times higher. This means modern gadgets make it so much easier to fabricate the image of a face than several years ago.
The endless race in pursuit of enhancing various external scanners further aggravates the problem, and we will have to update authentication data as new forgery techniques splash onto the scene. Nevertheless, the use of biometrics on personal devices makes perfect sense. Furthermore, major players use password-based authentication as additional security. Huawei products request a password every three days if biometric unlocking is enabled.
E-banking applications use biometric authentication after the customer has logged in, thus simply adding an extra layer of security to the whole process. Your email address will not be published.
Save my name, email, and website in this browser for the next time I comment.Biometrics are part of the cutting edge of technology. Put simply, biometrics are any metrics related to human features. As an emerging technology, biometric systems can add great convenience by replacing passwords and helping law enforcement catch criminals. Biometric identifiers also act as access control in secure environments, both physical and digital.
But the first question you should ask is: Is my biometric data secure from identity theft? These can include physiological traits, such as fingerprints and eyes, or behavioral characteristics, such as the unique way you'd complete a security-authentication puzzle. To be useful, biometric data must be unique, permanent and collectible.
Once measured, the information is compared and matched in a database. Every time you unlock a smartphone screen with a facial recognition, ask Siri for a weather update, or log in to your online bank account using your fingerprint, you're using biometrics.
You might use the technology every day to authenticate your identity or communicate with a personal device, but there are plenty of other uses for biometrics. In medicine, wellness exams might include retinal scans or genetic tests.
And when you use a credit card at a cash register, you'll probably supply a signature, which can be analyzed if the issuer suspects forgery. Basically, you record your biometric information, in this case a fingerprint. Fingerprints are just one form of biometrics. One of the emerging forms of biometric technology is eye scanning.
Usually the iris is scanned. Handwriting, voiceprints and the geometry of your veins are other biometrics that are uniquely yours and useful for security applications. Laptops and other computing devices are increasingly relying on biometric systems, and the trend has only just begun. Biometric authentication and biometric identification is an exceptionally secure way to log in to your devices and various services.
Plus, it can remove the hassle of remembering dozens of account passwords. While biometric systems provide convenience to commercial users, U. The original biometric was the ink-fingerprint process still used by law enforcement today. The rise of biometric identification has helped law enforcement agencies in major ways, but like any technology, this personal information can be misused by cybercriminals, identity theft scammers, and others in the case of a data breach.
There are serious privacy concerns when it comes to biometrics. Some of the major issues identified with biometrics include these:. There are some common-sense security measures you can make to help protect your biometric data, including these:. Biometric data could make the world more secure and more convenient. Following common-sense guidelines for security can play a role in helping to protect your privacy. Secure passwords are more important than ever as data breaches and leaks expose information.

Citizenship and Immigration Services today announced updates to its Policy Manual that address mobile biometrics services and fingerprint waivers.
USCIS requires biometrics from individuals who submit applications, petitions, and requests for certain immigration benefits. USCIS uses biometrics to verify identity, produce secure documents, and conduct required criminal and national security background checks.
In limited cases, at the discretion of the agency, USCIS may make special arrangements to collect biometrics from those who cannot attend scheduled ASC appointments in person, due to disability or other health reasons. This update clarifies that USCIS will not provide mobile biometrics services in prisons or jails for individuals who cannot attend their ASC appointment due to incarceration or detention. This policy applies only to individuals held in non-DHS custody.
For those in DHS custody, U. Immigration and Customs Enforcement will continue to collect biometrics. The updated guidance also clarifies that an approved fingerprint waiver is tied to the specific petition, request, or application listed on notice of the appointment for submission of biometrics at the ASC. In other words, someone cannot use an approved waiver for any other biometrics requirement for any future filings.
Individuals may qualify for a waiver of the fingerprint requirement if they cannot provide fingerprints because of a medical condition. These updates will improve consistency, fairness, and efficiency in how USCIS handles biometrics services. Visit the Policy Manual for Comment page for more information on stakeholder review and comment. Fingerprint Waivers The updated guidance also clarifies that an approved fingerprint waiver is tied to the specific petition, request, or application listed on notice of the appointment for submission of biometrics at the ASC.
Share This Page.Biometrics is the technical term for body measurements and calculations. It refers to metrics related to human characteristics. Biometrics authentication or realistic authentication is used in computer science as a form of identification and access control. It is also used to identify individuals in groups that are under surveillance. Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals.
Biometric identifiers are often categorized as physiological versus behavioral characteristics. Physiological characteristics are related to the shape of the body.
Biometrics and biometric data: What is it and is it secure?
Behavioral characteristics are related to the pattern of behavior of a person, including but not limited to typing rhythm, gait, and voice. Some researchers have coined the term behaviometrics to describe the latter class of biometrics. More traditional means of access control include token-based identification systemssuch as a driver's license or passportand knowledge-based identification systems, such as a password or personal identification number.
Since biometric identifiers are unique to individuals, they are more reliable in verifying identity than token and knowledge-based methods; however, the collection of biometric identifiers raises privacy concerns about the ultimate use of this information.
Many different aspects of human physiology, chemistry or behavior can be used for biometric authentication. The selection of a particular biometric for use in a specific application involves a weighting of several factors. Jain et al. Proper biometric use is very application dependent.
Certain biometrics will be better than others based on the required levels of convenience and security. The block diagram illustrates the two basic modes of a biometric system. Three steps are involved in the verification of a person.
In the second step, some samples are matched with reference models to generate the genuine and impostor scores and calculate the threshold. The third step is the testing step.
This process may use a smart cardusername or ID number e. PIN to indicate which template should be used for comparison. Second, in identification mode the system performs a one-to-many comparison against a biometric database in an attempt to establish the identity of an unknown individual.
The system will succeed in identifying the individual if the comparison of the biometric sample to a template in the database falls within a previously set threshold. Identification mode can be used either for 'positive recognition' so that the user does not have to provide any information about the template to be used or for 'negative recognition' of the person "where the system establishes whether the person is who she implicitly or explicitly denies to be".
The first time an individual uses a biometric system is called enrollment. During enrollment, biometric information from an individual is captured and stored. In subsequent uses, biometric information is detected and compared with the information stored at the time of enrollment. Note that it is crucial that storage and retrieval of such systems themselves be secure if the biometric system is to be robust.
5 Ways Biometric Technology Impacts Our Everyday Life: A Statistical Representation
The first block sensor is the interface between the real world and the system; it has to acquire all the necessary data. Most of the times it is an image acquisition system, but it can change according to the characteristics desired. The second block performs all the necessary pre-processing: it has to remove artifacts from the sensor, to enhance the input e.In order to identify a person, a security system has to compare personal characteristics with a database.
A scan of a person's iris, fingerprint, face, or other distinguishing feature is made and a series of biometric points are drawn at key locations in the scan. In the case of a facial scan, biometric points might be placed at the tip of each ear lobe and in the corners of both eyes, for example.
Measurements taken between all the possibly hundreds of points of a scan are compiled and result in a numerical "score" which might be quite largeunique for every individual, yet which can quickly and easily be compared to the previously compiled scores of all the facial scans in the database to determine if there is a match.
For security systems using cameraspeople recognition has become, in recent years, one of the most common forms of identification. The successful identification of an individual requires comparing an image of the individual to a database that contains the images of many people. However, comparing each image in its entirety, pixel by pixel, would be an extremely slow and expensive process. To solve this problem, biometrics are used. With biometrics, rather than compare the entire image, biometric points are placed at key locations, measurements between all the points are taken, and the results are compiled into a kind of "score.
When a new individual's image is obtained, all that is required for successful identification is for the system to compile the score based on the image's biometrics and then to compare this new score to the scores in the database—an easy task for a modern computer or laptop.
The goal of a recognition system is: given an image of an "unknown" person, to find a picture of the same person in a group of "known" or training images.
The difficulty is ensuring that this process can be performed in real time. A biometric system identifies images or videos of people automatically. It can operate in two modes:. For the scientist, Biometrics is the science of measuring physical properties of living beings and for the engineer it is the automated recognition of individuals based on their behavioural and biological characteristics.
By measuring an individual's suitable behavioural and biological characteristics in a recognition inquiry and comparing these data with the biometric reference data, which had been stored during a learning procedure, the identity of a specific user is determined. A biometric characteristic is biological or behavioural property of an individual that can be measured and from which distinguishing, repeatable biometric features can be extracted for the purpose of automated recognition of individuals.
An example is the face. This characteristic, recorded with a capture device, can be compared with a biometric sample representation of biometric characteristics. The biometric features are information extracted from biometric samples, which can be used for comparison with a biometric reference. Examples are characteristic measurements extracted from a photograph of a face, such as eye distance or nose size.Did you know that biometric identification management technology has been around since the 19 th century when police began to use it to track criminals?
The implementation of biometric technology is around us and expanding fast, quickly becoming a part of everyday life.
A number of biological characteristics such as fingerprints, finger and palm vein patterns, and iris and voice recognition have proven to be useful in the evolution of biometrics and biometric identification capabilities are now becoming standard on many devices we use each day. Many countries around the world including Iraq have already deployed biometric border security systems for fast and accurate identification of both local and foreign travelers.
Biometric identification management deployments for border security include: national databases, immigration, and e-passports. Biometric border control systems ensure that an inadmissible person does not pass through immigration unidentified at airports, seaports, and other border control environments.
Takeaway: These statistics reflect that biometric technology border control implementations at airports and other border control environments is successfully closing many loopholes in border security. Biometric identification management for border control increases security and protects individuals and nations.
The main application of healthcare biometrics refers to the use of biometric solutions in medical facilities for secure patient identification. Additional uses of biometrics in healthcare include time and attendance workforce management and single sign-on SSO to safeguard protected health information PHI.
Health records are among the most valuable personal documents to protect. Medical identity fraud can endanger individual health and place you at a higher risk to be a victim of medical errors. Furthermore, safeguarding access to PHI is critical for patient safety and to maintain a high level of patient data integrity.
The global market for healthcare biometrics is projected to expand at an extremely high Implementing biometric technology also prevents medical identity theft and secures sensitive patient information.
Takeaway: This data shows that implementation of biometric technology not only ensures patient safety, but also protects medical identities and privacy and prevents individual patient information from being stolen or compromised.
Biometric identification allows end users the ability to provide physiological characteristics in place of a password, token, or personal identification number PIN as a secure method of system or database access. For biometric authenticationimplementation potentials are limitless. This does not even count the financial turmoil and emotional distress people have to go through as victims of identity theft. From banking and business enterprises to accessing homes, cars or even personal computers, biometrics provides the highest level of security when it comes to protecting privacy and providing secure access.Introduction to Biometrics
Takeaway: The use of biometric technology ensures protection against identity theft as well as secures access to your home, car, computer and even mobile phone. The threat of security breaches and unauthorized facility access has left many member-driven organizations searching for a safe and effective way to manage their databases. Due to the limitations of membership access systems that rely on plastic ID cards or PINs, biometrics has quickly become a necessity for membership management organizationssuch as gyms, churches, clubs, and libraries.
Beyond data security, biometric technology also provides an efficient and productive way to manage memberships, already proven to be the most effective solution for secure and orderly management of member information. Membership-based organizations are quickly becoming aware of the value of biometric technology such as fingerprint recognition.
The impact of biometrics in membership management is immense, and still evolving. Takeaway: Membership facilities are more secure than ever and biometrics helps membership costs from increasing because it prohibits unauthorized individuals from accessing the facility.
Biometrics also makes membership management more efficient, thus reducing expenses. The use of biometric technology in workforce management for time and attendance has almost become a necessity.
More and more companies around the world are adapting biometric technology as a more secure employee identification solution with their workforce management systems.
Many organizations now rely on biometric time clock s for use in workforce management to help secure:. Takeaway: The implementation of biometric technology in workforce management such as employee time and attendance increases employee productivity and accountability, eliminates time theft and buddy punching, maximizes authentication accuracy, and increases return on investment ROI.

You can view their Web site at www. Start Your Free Trial. Don't Worry! You will not be spammed.Biometric authentication is simply the process of verifying your identity using your measurements or other unique characteristics of your body, then logging you in a service, an app, a device and so on.
To understand it better, just know that biometrics is the name for any type of body measurements and calculations. Biometric identification verifies you are you based on your body measurements. Biometric authentication goes one step further and uses that information to compare you against a database and enters your information in a service. Think of it like this: biometric identification is like a neighbor who looks through the peeping hole at the 2 people who just rung the bell.
The neighbor decides which one of them is Dave based on height, hair color, eye color and so on. Biometric authentication is the neighbor who looks through the peeping hole to see who is calling the door. Biometric authentication works by comparing two sets of data: the first one is preset by the owner of the device, while the second one belongs to a device visitor.
For instance, you might have a slightly sweaty finger or a tiny, tiny scar that changes the print pattern. There are quite a few types of identifying a user by way of his own body. Both Google and Apple store your fingerprint on the device itself and do not make a copy of it on their own servers.
So even if a malicious hacker reaches this mathematical representation, he cannot reverse engineer it to reveal an actual image of your fingerprint. Not only that, but the fingerprint data itself is encrypted. This will get them access to your unlocked phone, but not to a copy of your fingerprint, so it differs from stealing a password.
Android phones operate under similar guidelines. They store the fingerprint data in a secure part of the main processor called Trusted Execution Environment, or TEE for short.
Just as with Apple devices, fingerprint data is stored in an encrypted state. In addition, removing a user from the device should also delete any fingerprints stored on it. While Apple has moved away from fingerprint scanning authentication and replaced TouchID with FaceID, other companies still rely on it. Indeed, ina lot of smartphone developers are aiming to incorporate fingerprint scanners in the screen itself.
Vivo is the first one to market such a device. Whenever the OLED screen lights up, it also illuminates your fingerprint, which the sensor sees and then compares it to the info already stored.
For users, the result is a seamless experience: simply touch the screen with your finger and your phone will unlock. Despite these limitations, the technology has made its way as a security feature in airports, banks, and other sensitive buildings.
How it works. During verification, an iris scanner will again emit infrared light to spot those hidden details.
