A team of Michigan State University computer scientists led by Indian Institute of Technology (IIT) Kanpur alumnus Anil Jain has built the first three-dimensional (3-D) model of a human fingerprint.
The development will not only help today’s fingerprint-matching technology do its job better, but could eventually lead to improvements in security.
Jain, a University Distinguished Professor of computer science and engineering, and his team have developed a method that takes a two-dimensional image of a fingerprint and maps it to a 3-D finger surface. The 3-D finger surface, complete with all the ridges and valleys that make up the human fingerprint, is made using a 3-D printer. It creates what Jain’s team calls a fingerprint “phantom.”
Imaging phantoms are common in the world of medical imaging. For example, to make sure an MRI machine or a CT scanner is working properly, it needs to first image an object of known dimensions and material properties. In this case, the ultimate goal is to have a precise fingerprint model with known properties and features that can be used to calibrate existing technology used to match fingerprints.
While the 3-D model doesn’t yet have the exact texture or feel of a real finger, it could advance fingerprint sensing and matching technology. Read more
Now, diabetes can be detected at an early stage by just taking a photograph of retina. An Indian company has developed a prototype of a portable device that enables diagnosis of the disease through retinal scan.
Trivitron Health Care, a leading manufacturer of medical devices, has developed kiosk-type device in collaboration with Indian Institute of Technology, Madras (Chennai) and LV Prasad Eye Institute, Hyderabad.
“The device will be available in the market in next six months after a patent is obtained,” Trivitron group of companies founder Dr G S K Velu told a reporter from DNA. “In a country like India which has second largest number of diabetics, the device can help in early detection and prevention,” said Dr Velu.
At present, diabetes is detected through blood tests, both fasting and post-prandial. This new device, however, takes into account changes that occur in retina of patients during early stages. The company has developed algorithms from a database of the changes brought about by diabetes in patients. The software in the device compares the retinal scan of the patient with the database and arrives at a conclusion. “It will hardly take 2-3 minutes to get the results and the product will be cost-effective also,” Dr Velu said.

Scientists at Intel are developing a new technology which can verify a person’s identity with a wave of the hand. A biometric sensor in a laptop or tablet computer scans the unique pattern of veins in a person’s palm to verify their identity. The technology could do away with the multiple passwords most people use for websites.
“The problem with passwords — we use too many of them, their rules are complex, and they differ for different websites. There is a way out of it, and biometrics is an option,” Sridhar Iyengar, director of research at Intel Labs said. Iyengar added that the palm scanning technology worked much better than the finger-print scanners used on some laptops today. Read more
Pune-based BioEnable Technologies has launched a scanner enBioScan-C1 that has been certfied by US Federal Bureau of Investigation (FBI) for Personal Identity Verficiation (PIV).

The scanner is flexible and user friendly in design. “It is a combination of high quality and cost effectiveness which will revolutionize the single finger scanner market,” says Pradeep Bhatia, managing director of BioEnable Technologies.
Along with design customization feature, the device is capable of capturing extremely high quality images. It is expected to cater to the needs of the government or semi-government projects as it is both customizable and compatible withUnique Identification Authority of India’s Aadhaar authentication server.
The scanner also complies with ISO standards such as ISO 19794, ISO 19792, NIST and ANSI, and “with world class algorithms and hardware, it outperforms FRR/FAR requirements set by STQC/ UIDAI,” says Bhatia.

A New York-based biometric security company, Hoyos Group has unveiled a new security product, dubbed the EyeLock. According to reports, it is probably the first and only portable iris-scanning device for consumers. The device, which is the size of a standard business card and weighs about 113 grams, connects to the users computer by a USB cable. Once the EyeLock software is installed, all that the user has to do to is wave the scanner in front of her eye to automatically log in to any password-protected application or website whether that’s Facebook, Twitter, PayPal, or a bank account.
