HOW BIOMETRIC HAND VASCULAR SCANNERS WORK |
| |
|
| |
The Vascular Pattern Scanner uses passive infrared technology to capture an individuals unique Vascular Pattern from below the surface of the skin on the back of their hand. This simple to use, very fast, hygienic and highly accurate solution allows for a unique personal template to be captured, encrypted, and then stored a variety of ways. The individual subsequently presents the same hand to the scanner, the live vascular pattern is matched to the stored template and the individual is identified. |

With the option of storing the encrypted unique personal template on media such as a smart card and 2D barcode, the scanner communicates with Identica s proprietary Universal Controller (the UC-2) and biometrically verifies the user against the stored template on the media. Therefore the stored template stays with the user addressing privacy concerns. The VP-II can also be used in conjunction with Identica s T-Module, using TCP/IP to communicate with the network, to store and access the biometric template. The user either keys in a personal identification number (PIN) or presents a proximity card, and then presents the back of the hand for identification. The live vascular pattern is then compared to the network-stored template and the identity verification message is sent to the access control / time and attendance / credential verification system. |

Utilizing Identica’s Software Development Kits (SDK), OEM’s and Solution Providers can rapidly develop fully integrated applications with current, legacy and future TCP/IP based entry management, time and attendance and credential verification systems. |

The United States has implemented face recognition to ensure that terrorists in its watch list database do not slip through its borders. The Singapore immigration authority has implemented iris scans at one of its checkpoints to facilitate the immigration process for motorists travelling between Singapore and Malaysia. Schools and offices are installing biometrics devices to restrict and control individual access while large organisations are replacing traditional punch card devices with biometrics to better manage time and attendance. |

Without a doubt, biometrics is here to stay. This is because traditional security and access devices still depend heavily on ‘what we have’ (keys, cards) and ‘what we know’ (personal identification numbers, or PIN). This means it is still subject to loss and abuse. Biometrics, on the other hand, relies on ‘what we are’. As a result, after the first fingerprint biometrics system was introduced about 30 years ago, market awareness for biometrics solutions is finally gaining momentum, and security-sensitive organisations like government agencies, financial institutions, multinational enterprises and utility management companies are among the early adopters. |

In the biometrics market, hand geometry and fingerprint scans are the most commonly deployed solutions. Thanks to the Hollywood blockbuster Minority Report, we are also familiar with iris scans, while face and voice recognition already have a popular following. However, brace yourself for this: the vascular (vein and capillaries) pattern at the back of your hand can also be a unique identifier. Considering the fact that biometrics is the science of measuring the behavioural and/or physiological characteristics of an individual, basically any part of the body can be used in biometrics.The reason for the different emerging technologies is because each biometrics system possesses one or two significant advantages and suffers in other aspects. |

While consumers are spoilt for choice,they are also left mulling over the best system – in evaluating a cost-effective system, one not only considers overall costs but also the product usability, flexibility of use, maintenance costs, user convenience, accuracy and security aspects. |

When hand vascular pattern recognition technology was introduced in the market a few years ago, the other biometrics players did not pay much heed to it because, after all, any part of the body can be used as biometrics, including ear shape and even body odour. In addition, little research has hitherto been conducted on hand vascular pattern biometrics. However, as time went by, this new technology has silenced the naysayers and created a stir among the other players. This is because hand vascular pattern biometrics boasts several key advantages and benefits. |
