Biometric palm vein smartcard used to access medical records

The first implementation of a biometric palm vein authentication system to access electronic medical records has been implemented at the Hospital for Charged Particle Therapy at the National Institute of Radiological Sciences (NIRS) in Japan.
The innovative system enables users to access electronic medical records and is being used to prevent unauthorized access to the hospital's data.
A leader in charged particle therapy, the hospital is involved in a wide range of medical activities based on its radiology examination and care, including radiation diagnoses for cancer, treatment, nuclear medicine, and care for patients who were exposed to atomic bombs.
To log into the system, the user inserts an integrated circuit (IC) smartcard in which the user's pre-registered palm vein pattern data has been registered, and holds his or her hand over the palm vein authentication sensor.
The palm vein pattern obtained from the authentication sensor is then compared with the data read from the smartcard.
If the patterns match, the user is granted access to the electronic medical record system.
Compared with the conventional ID and password input systems, Fujitsu's PalmSecure restricts unauthorized access, reinforcing the security that protects the hospital's confidential data.
Additionally, the new system includes enterprise user authentication (EUA) which complies with Healthcare Enterprise Information Technology Infrastructure standards, allowing users to also access the medical imaging management system and report system via single sign-on.
Because palm veins are beneath the body surface, they are extremely difficult to forge. Compared to the pattern of veins in fingers or the back of the hand, palm vein patterns are more complex - again, increasing the difficulty of forgery - and more stable, as they are less affected by temperature and other external impacts.
According to Fujitsu, the system has a false acceptance rate of less than 0.00008 percent and false rejection rate of 0.01 percent.
Unlike fingerprint-based authentication methods, for which registration and verification of biometric data cannot be successfully completed if the surface of the skin is impacted by abrasion or dryness, contactless palm vein authentication has negligible susceptibility to such external factors.
In developing its palm vein authentication technology, Fujitsu collected data samples of 150,000 palm vein patterns from 75,000 individuals worldwide to verify authentication accuracy and applicability rate. In this process, there were no cases in which the data sample could not be registered and verified.
Meanwhile, the Biometrics Institute of Australia has announced it will hold its annual conference on June 7-8, 2007.
The event will focus on biometrics including commercial and government applications, technology updates, privacy considerations, standards, interoperability, testing & evaluation.
