Creating Fake Fingers for Secure Biometric Fingerprint Authentication As the unrelenting demand for smartphones continues to increase, many technology companies are looking for ways of making such devices easier, faster, and more user friendly. Many smartphones are equipped with fingerprint readers, allowing the user to access their phones securely and quickly without having to type in their pin or passcode. This prevents users from having to remember dozens of random passphrases that, in theory, a hacker could potentially guess and be granted access into. However, this poses a serious question - How secure is fingerprint authentication and why should consumers trust that this technology will keep their information safe? Similarly, …show more content…
Capacitive readers work by measuring the differences in capacitance between the ridges and valleys to map out the fingerprint. Because of this, unlike the optical reader, there is no light component necessary in order to read the fingerprint. Thus, the capacitive sensors can be much smaller, and are commonly seen in smartphones, laptops, and tablets. In figure 1 below, the difference between the fingerprints captured by the optical (left) and capacitive (right) readers can be seen. Due to the smaller size of the capacitive reader, it captures a smaller area of the fingerprint. Anil Jain and Joshua Engelsma of Michigan State University are creating life like fake fingers, commonly referred to as “spoofs.” These pigmented, conductive silicon spoofs share properties similar to human skin; their mechanical, optical, and electrical properties allow it to act basically as a finger. With these spoofs, creators of fingerprint readers can use them for two purposes: 1. remove the discrepancy between optical and capacitive readers and 2. enable readers to detect for only real fingers to be granted access. The current problem with many of these readers is that if it was recorded on one type of reader, and the user tried to authenticate with a different type, it would fail. These spoofs will allow developers to test their systems, without having to use their own fingers over and over again, while also ensuring consistency. In
During the identification phase, the user puts the finger on the same sensor, generating a new fingerprint image or template called query print. Minutiae points are carried out from the query print, and the matcher module compares the set of query minutia with the stored minutia templates or image in the enrollment database to find the number of similar minutia points. Because of variations present in finger placement and pressure applied to the sensor, the minutia points take out from the template and query fingerprints must be lined up, or submitted before matching. After line up the fingerprints, the matcher decides the number of pairs of matching minutiae-two minutiae points that have similar location and directions. The system decides the user's identity by comparing the match score to a
Here, instead of U.V light, a visible light was used. The light source used was a variable light source, which enabled us to change the wavelengths of the visible light. The latent fingerprint was attempted to be excited using a variable visible light source to determine if the fingerprint fluoresce within a specific visible light wavelength. The light wavelength was increased from 425nm to 700nm with 25nm in each step. Multiple images were photographed within each level, using spectral filters and camera settings in order to capture any fluorescence that the fingerprint might
Portable equipment often doesn't need passwords enabled. Mobile device apparatuses often need passwords on validating clients and control entry should information saved on the gadgets. a large number unit have those specialized foul abilities should backing passwords, particular ID number numbers (PIN), or design screen bolts to Confirmation. Some versatile apparatuses likewise incorporate a biometric spectator to examine a finger impression to verification. However, ane data demonstrates that shoppers sometimes utilize these instruments. Additionally, if clients would utilization A secret key alternately PIN they often decide passwords alternately PINs that camwood make effortlessly decided alternately bypassed, for example, 1234 or 0000.
We consider the situation where an attacker is already in possession of the smartphone. This scenario is common because the user might forget her smartphone somewhere, i.e., in her office, canteen, etc., or an attacker manages to steal the smartphone (e.g., through pickpocketing, etc). More specifically, we target three scenarios: (i) an attacker accidentally finds the smartphone, (ii) the attacker is victim's friend or colleague (who knows about the implemented mechanism), and (iii) an attacker who tries to mimic the user behaviors (e.g., using recorded video, etc) to unlock the victim's smartphone.

The solutions presented in the report have an edge over different models. The reason is that, once an attacker obtains access to a unique finger impression template, he can claim to be a validated client. Yet,
About 2 % of the population have poor quality of fingerprint, especially the elder people and manual worker. For these cases one need to consider other biometrics or any other solution.
Any moist or wet biological evidence (blood, body fluids, plants, etc.) like the lottery ticket on the counter with the blood smeared print on it should be collected wearing gloves it should then be placed in a clean unused paper container such an envelope, and or small bag and transported back to an evidence receiving area, it should then be taken out of the bag and allowed to air dry thoroughly. The Ninhydrin process should be applied to this piece of evidence to obtain noticeable prints.
The use of fingerprinting as a means of identification was born out of the need of law enforcement officials to have permanent records that could determine if a convict had been previously arrested or imprisoned. Before the advent of fingerprinting, law enforcement used a number of different methods to try to accomplish this. Ancient civilizations would tattoo or physically maim prisoners. In more recent times, daguerreotyping (that is, photographing) was used, but proved to be less than reliable, because people had the ability to dramatically alter their appearance (Skopitz). As a result, this method too, became obsolete with the discovery of fingerprinting, an absolutely infallible
Every time somebody touches something, they leave behind a unique signature that forever links them to that object. This link is their fingerprints, which are unique to every person, for no two people have the same set, not even family members or identical twins. Palms and toes also leave prints behind, but these are far less commonly found during crime scene investigations. Therefore, fingerprints provide an identification process that is applicable to background checks, biometric security, mass disaster identification, and most importantly, crime scene investigations. Fingerprints are so differentiated because they are made up of distinct patterns of ridges and furrows on the fingers. The ridges are the “raised” portions of the prints, and the furrows are the “recessed” portions. This perceived uniqueness has led some people to falsely accept fingerprint analysis as absolute scientific fact. Although overall fingerprints are reliable, there are definitely situations where their accuracy can come into question.
Biometric technology offers an alternative to the most used system currently in place in most operations: passwords or personal identification numbers (PIN). Instead of users inputting their password or PIN, users interact with a computer terminal that will scan their finger, face, voice, retina, etc. to identify them. Many of the next generation personal computer systems will have integrated biometric technology so that no external hardware is needed. In the mean time, users can buy small peripherals, like a mouse with integrated biometric technology or a small finger terminal for finger scans, to secure their personal computers.
The world’s major credit card companies are using finger scanning devices to protect credit card information and save the consumer from credit card fraud. Walt Disney World in Orlando has implemented a hand scanning system to prevent people from
Fingerprinting is used for many things, such as a robbery, or at a crime scene. Fingerprints were first discovered in 1870 by Alphonse Bertillon, who was a French anthropologist. In 1892, Juan Vucetich had made the first criminal report using a fingerprint. In 1905 America used fingerprints for identification. When America started using fingerprints for identification they had to match the fingerprints manually when needed. When technology was able to enter fingerprints, and match them with anonymous ones, it helped identification immensely.
The final main biometric technology used is fingerprint recognition. This is definitely the most widely used biometric technology. This type of biometric has been used for many, many years. Because of this, fingerprint recognition has been known as the most primary and accurate identification method used to identify a person. The modern fingerprint recognition is all done electronically. There are two main ways of analyzing fingerprints electronically. The first plots points on the ridges of a person’s fingers that enable the computer to compare to different fingerprints. The second method uses patterns of a fingerprint
Biometrics is a method of identifying an individual based on characteristics that they possess, typically physiological features such as a fingerprint, hand, iris, retina, face, voice, and even DNA. Some methods of biometrics security even use multiple physiological features or multimodal biometrics to provide superior security than a single form of biometrics can provide. Why are biometrics important in the field of information security? Biometrics provide a remarkable amount of security for information because biometrics are unique to each person, and thus cannot be lost, copied, or shared with another individual. This security allows for biometrics to provide a means to reliability authenticate personnel. The importance of biometrics can be further divided into the history of biometrics and why it was devised, past implementations of biometrics, current implementations of biometrics, and future implementations of biometrics.
