Printing with DNA

05 Apr 2007

DNA --- Tokyo-based Ko-sin Printing has developed a printing process that allows authors to add a more personal touch to their printed works by using ink that includes their DNA.

Once DNA is extracted from a human (or animal) hair or nail sample provided by the author, it is blended with a special ink and used in the printing process. Ko-sin has already put the technology to use in some self-published autobiographies whose title pages are printed with ink that includes the author's DNA. Mixing DNA in with the ink does not alter the appearance of the page, the company says.

Ko-sin also claims it is possible to extract genetic information from materials printed using this process. When the company sent a sample page to a DNA laboratory, the lab technicians were able to isolate and extract the DNA from the page.

The patent-pending printing process was invented by Ko-sin's president, Mr. Yoshida, who drew upon his years of experience researching and developing ink. Ko-sin hopes the process will appeal to autobiographers who want to add value to their work by including their DNA, or to people who wish to insert the DNA of beloved pets into printed materials. The company is now investigating other potential applications.

Iris recognition technology for mobile phones

06 Nov 2006

Iris recognition techology for cellphones -- On November 6, Oki Electric announced the development of iris recognition technology for camera-equipped mobile phones. Unlike Oki's previous iris recognition technology that relies on infrared cameras for the iris scan, the new technology uses ordinary cellphone cameras.

With plans to make the technology commercially available in March 2007, Oki hopes to boost the security of cellphone payment systems.

According to Oki, any camera-equipped cellphone or PDA can perform iris recognition once the special software is installed. Identification accuracy is said to be high, with only 1 in 100,000 scans resulting in error, and the system can tell the difference between flesh-and-blood eyes and photographs.

Fingerprint sensor in your wallet

28 Jul 2006

Fingerprint sensor by Seiko EpsonSeiko Epson has developed a paper-thin fingerprint sensor measuring 0.2 millimeter in thickness, which may help bring an extra level of security to a range of items in the future. When touched, the sensor reads fingerprint patterns based on the faint electric current emanating from the user's fingertip.

The fingerprint sensor's ultrathin profile means it can easily be incorporated into a variety of commonly used items. Among the applications that Seiko Epson is targeting are self-authenticating credit cards, in which a tiny on-card processor is used to compare the captured fingerprint data with the user's fingerprint data stored in an embedded memory. A non-matching fingerprint would render the card unusable, preventing abuse in the case of loss or theft.

The company aims to commercialize the sensor by 2010.

China’s body odor databank sniffs out crime

22 Mar 2006

Smell databaseForget about fingerprints and DNA -- the way you smell has been added to the list of biometric data that can be used as personal identification. Police in China are now using body odor data to identify suspects in criminal cases.

A laboratory official at the Nanjing Police Canine Research Center has created a "body odor databank" designed to assist in criminal investigations by matching crime scene odors with the smells of individual criminals. With the cooperation of police, the laboratory is now collecting the odors of people with criminal records. So far, 500 different samples have been collected and registered in the database.

According to the official, clues obtained from smells have played a key role in solving a number of cases. This is because even the craftiest criminals are unable to remove all traces of their odor from a crime scene.

Pirkus-R, the Bluetooth bot with facial recognition skills

17 Mar 2006

KDDI R&D Laboratories and I Bee, K.K. have upgraded their Bluetooth-enabled bipedal walking robot, named Pirkus-R Type-01, with facial recognition capabilities. Equipped with a built-in CCD camera, the 29-cm (1-foot) tall personal (build-it-yourself) robot can spot faces that it would like to inspect at closer range. Pirkus-R is able to self-correct its direction as it makes its approach, and once it captures a facial image, it can determine whether or not the person is registered in its file.

Pirkus-R Type-01

I Bee was responsible for developing the robot, which can be controlled from an au Bluetooth-enabled handset (W21T/W31T/W41T) using a BREW application. As I Bee continues to develop Pirkus-Rís control and facial recognition technology and the 8-bit CPU that links the robot with the handset, the price (250,000 yen for the deluxe model) may start to come down.

The robotís facial recognition technology is based on technology that KDDI developed for mobile phones. KDDI has improved upon previous facial recognition technology, which used to require you to position your face directly in front of the camera in order to be recognized. Other problems with the human-robot interaction have been addressed, including lighting-related problems that occurred when capturing images. Pirkus-R is able to automatically detect which direction you are facing, and is no longer at the mercy of variations in lighting conditions. Furthermore, because it is equipped with Bluetooth technology, you can use your BREW-enabled au handset to check Pirkus-Rís operating status and facial recognition results. Of course, you can control it from your phone, too.

Pirkus-R Type-01 is scheduled to appear at the Robo-One fights being held this weekend (March 17 to 19) at Panasonic Center Tokyo.

UPDATE 31/Mar/2006: Tempusmaster at www.robots-dreams.com has posted video of Pirkus-R in action (sort of) at Robo-One. The video suggests a need for further improvements to Pirkus-R's facial recognition capabilities. (Link)
