This Innovative Fingerprint Scanner can Discern Fake Fingerprints from Real Ones


Revolutionary Fingerprint Scanner – Discerning Fake Fingerprints

One can beware of career crooks and villains now with BitFlow, the machine vision technology company that has created a revolutionary fingerprint scanner with the potential of discerning fake fingerprints from the real ones. While fingerprint scanners could be easy to fool, the new tech of BitFlow tends to scrap the process of photo scanning in favour of a method that looks inside the person’s finger.

Developed in amalgamation with the scientist at the Langevin Institute in Paris, France, the new scanner can quickly and accurate capture what according to the team is a person’s internal fingerprint. Just as the fingerprints are seen on the surface of a finger, an internal fingerprint has the similar topographical features that resides around half a millimetre below the skin.

Besides this, the system also has the potential of imaging sweat pores in the finger of the person, thereby enhancing its means of recognizing an individual. The internal sensor, engineered by Langevin Institute postdoctoral researcher Egidijus Auksorius and scientific instrument professor, Claude Boccara, is based on a full field optical coherence tomography of FF-OCT.

FF-OCT Depends on 2D Detector

Different from the standard optical coherence tomography that makes use of the 3D data as well as lasers, the FF-OCT tends to depend on a 2D detector thus making it easy as well as faster for utilisation. Essentially the images of an internal fingerprint could be captured within a second on using this tech which is of great advantage for the fingerprint scanning industry.

The scanner analyses the difference interference patterns produced when in use, after a beam of light reflects off a sample, which is the finger, against a reference beam of light. For example when a light beamed at a finger tends to register with the system, it has the capabilities of seeing the different grooves, patterns as well as pores linked with someone’s unique fingerprint.

The reference beam of light that is a pure beam enables the scientist to precisely read the variations and chart the grooves and the patterns. As per the published press release of BitFlow, a study which was done by the Department of Homeland Security, it was observed the wearing of fake prints, or spoofing a fingerprint sensor beats a scanner by about 80 percent of the time.

Produces Fingerprint Biometric Data

Taking this into consideration, it is a surprising percentage in any given capacity. Auksorius and Boccara’s collaboration with BitFlow seems to be a forensics expert’s best colleague. The system is expected to produce fingerprint biometric data which is less vulnerable to spoofing and could also be popular if the concern for security of 2D scanners tends to rise.

However, with the other 3D imaging systems like the ones based on ultrasonic technology developing at the same time, size and the cost would be essentially important and the FF-OCT system could envisage stiff competition in that sphere. As per a scientific paper published in a leading journal, Auksorius and Boccara had initially used an expensive InGaAs camera though recently had demonstrated that images of the internal fingerprints of same quality could be recorded on utilising a new silicon camera from Adimec which is due to the camera’s high frame rate together with the pixel’s high capacity. A compact LED source releasing at 780 nm is utilised to provide the illumination.

Iris Scanners Can Now Identify Us from 40 Feet Away

Nowadays, the government of every country believes that all the traffic cops should be provided with some high tech systems such as cameras or any other technology because these can help them to make out the potential risks from a secure distance. Thus, the latest designs of iris scanners may give a great help to the cops.

Iris scanner has been a portion of bio metrics. It is because just as finger prints, all people have unique iris. But, the iris scanners, which are utilized in the present days, would need the individual to give their permission for the analysis. Besides, the individual would need to come near the system to scan their iris. It is quite dangerous if the official needs to scrutinize the iris of any possible risky item. This is the main problem of the common iris scanners.

However, the researchers of Carnegie Mellon University have tried to develop an Iris scanner system with long range. This will be able to make out people who are present at a distance of nearly forty feet.
An engineering professor of Carnegie Mellon, Marois Savvides has found out a solution, which can assist the traffic officers to recognize the criminals or dangerous things within a very safe limit. This Iris scanner technology of Savvides is able to discover a person while they glance at the back view mirror. It is for the first time this kind of a device has been invented.

New system of Savvides is very easy to use 

In a discussion, Savvides stated that the researchers have made the overall user experience quite less disturbing and more comfortable. Moreover, he also said that there are not any X-marks-the-spot. Even there is no site you need to stand.

Savvides’ new Iris scanner system with long range can subtly scrutinize the iris as well as face of any individual. An associate of the Carnegie Mellon stated that in addition to the traffic stops, such technology may also get place at ID confirmation ports at all sites. This can also substitute the login system of laptop which is generally noticed in some other bio-metric structures.

However, the latest technology has some drawbacks that are clarified by the associate of the Carnegie Mellon with the help of some pictures. One of the demerits is that the government will be able to check face and even iris of every individual who is walking on a particular city without any approval or knowledge of the individual. It indicates that the scanner can make use of algorithmic techniques and spot any person who may be a disguised political advocate.

Prevention of many crimes with Iris scanner 

Savvides said that one of the major problems in this world is human trafficking and also sex trafficking. The children are often being kidnapped and trafficked across some borders. If the latest system can be placed at the borders, then it could make out them. A non-profit unit of Virginia, Seraphim Global that opposes all types of human trafficking, decided to deal with Savvides in order to attain their objective.

Eye-Tracking Tech Makes Virtual Reality Hands-Free

Eye Tracking Tech – FOVE Headset

People with certain disabilities can now look forward to new means of communication and interaction with the advanced virtual reality headset, which could be game changer for the entertainment industry according to developers.

FOVE headset utilises eye tracking technology to enable the wearer, a completely hands free virtual reality wherein the action could be controlled with the help of eye movements. The virtual reality technology has been advertised as the next social and communications platform with firms like Oculus VR being one the market leaders with their Oculus Rift, virtual reality glasses.

However, LochlainnWilson, FOVE’s co-developer as well as chief technology officer, states that their unique technology provides an immersive experience which has not been provided by anyone. He further adds that `eye tracking is game changing in VR.

 It allows for much more complex and subtle interaction than has been possible previously. By knowing exactly where the user is looking, characters in virtual reality can react to your gaze and return it naturally or avoid it or respond or question. But what really sets us apart is eye-tracking, of course. So with eye-tracking we enable a whole new world of interaction in VR. We enable really sensitive emotional experiences that could only otherwise be experienced in real life’.

Two In-Built Cameras – In Head Mount

This eye tracking technology utilises two in-built cameras which is in the head mount for recognizing the user’s eye movement. Presently users perform a short calibration system wherein the device tends to scan the user’s eye and track the movement of their iris.

According to the team, the next version of the device would use iris recognition for loading user profiles. Wilson informs that the device delivers an experience which was previously only possible in science fiction. He comments that `in the control sense, we enable science fiction like user interfaces like Tony Stark’s Ironman and Jarvis, just at a glance user interface respond and updates information, targets an enemy, hits another button and they’re blown up. It is pretty cool in that sense. In a more technical side of things, we enable what is known as foviated rendering, where you focus the processing power exactly on what the user is looking at. By doing this, we drastically reduce the computing power required to deliver a believable scene’.

Various Fields to Benefit with Technology 

Wilson also stated that the technology presents an occasion to re-imagine various tasks and social interactions in the field of education and medicine. This start-up was originated by Wilson together with CEO Yuka Kojima and with the games industry being their focus, the creators of FOVE convey that their device could bring about virtual reality to cinema, enabling viewers to interact within the headset with objects and characters.

He has also informed that they always thought that their technology would have applications which would be outside gaming. It would be suitable for education, training, psychology, research, neuroscience, with various fields which could benefit on having this form of technology.

He also informs that the technology provides a freedom of expression as well as creativity for individuals with certain disabilities, providing a level of communication which was otherwise impossible. The expected price point conveyed by him would be around $400.

The company would now launch a crowd funding campaign to raise $250,000 USD, on the Kick-starter platform, for a flawless product and begin developing its headsets.

Technology Turns Touchscreen Displays Into Biometric Scanners

Some of the researcher representing and working at the Yahoo Labs have developed a very affordable alternative to the current fingerprint sensors available on the phone. They have developed a biometric system which is being called as the Body print. This biometric system will only require the capacitive touch screen displays of the devices to authenticate the body parts of the user.

However, on the down side, since the touch screen displays have lower resolution of the input when compared to other specialized sensors, the new biometric system will require the user to make use of the larger parts of their body. The user will simply have to press any of these parts on the screen to get access to the device. This biometric system not only works as a security gatekeeper for the phone, but is also has many other benefits and applications. This system has perfect ability to recognize the fist, ear, set of five fingers, phalanges, and the palm of the user.

Applications of the new biometric system: 

A simple example of this biometric system application is the fact that the user can configure the device system to only answers calls when the device has been able to detect the ear of the users pressed to the phone. Body print that was recently launched at the 2015 Computer-Human Interaction Conference (CHI) in Seoul, South Korea was able to accurately identify different parts of the human body as well as the owners of the system for nearly about 99.98 percent of all the times during all the tests that was conducted using 12 participants. But if it is important that the creator is this biometric system and his team, try and test this system on a wider scale before it can be released for commercial use. This application is perfect to keep the files and documents saved from inquisitive people.

This creation has come as a new breather for many companies who are still afraid to try on the biometric systems. Not many companies have tried to take complete advantage of the full potential of this system. Most of the latest smartphones are built with the fingerprint biometric system and how might be the perfect time for all these companies to raise the bar a bit higher.

In present all the finger print scanners are available on some of most high end phones but the Body print will allow all the smartphones have all the features of a biometric system.

This firm is not only innovating latest technology but also planning to extend its research in the field of technology, as Marissa Mayer, who is the CEO of Yahoo stated that firm might compete with the other leading technology of same field such as; voice-based virtual assistants or Cortana of Microsoft, Siri from Apple or Google Now from Google. It is expected that Bodyprint will arrive in the market in the form of app to support touch screen of almost all smartphones.
