6 Alternative Biometric Technologies
Many government and business agencies are implementing various biometric technologies. Smartphones are already equipped with fingerprint scanner and it is probably the most popular type of biometric scanning. Here are other things that can be:
- Hand-palm print: Just like fingerprint, people also have unique hand-palm print. Employees will need to submit their hand prints for electronic storage. The data can be used for comparison against future scanning. It’s a foolproof technology and perpetrators will need to have surgical alterations that match our hands to break into the system.
- Iris pattern identification: An IR scanning device will scan the iris in our eyes to map its distinct features. Our iris has unique pattern that’s similar to fingerprint. However, while it is possible to fake fingerprints by lifting any trace of fingerprint and make a mold of it; fooling an iris pattern identification can be much more difficult. It is difficult to acquire this data passively.
- Facial recognition: Facial recognition is a relatively simple system, known for its accuracy and speed. Each person has unique face and facial traits can be mapped and measured. When the identity of someone is known, a high quality image of the person can be used to gather preliminary facial data. However, this may represent a potential risk; because perpetrators may use proper facial photos of someone and use it to attack the system. Facial characteristics may also change over time; so the system should be aware of this factor. Hair style could change, people may lose or gain weight significantly; so sometimes it is necessary to update the system. Facial recognition could be used in nation-wide security mechanism. People can be identified in public cameras and their faces are correlated with the central database.
- Speech recognition: Each person has unique speech features and they have specific signature that can be matched to distinct individuals. Our speech could have specific pitch and voice inflection. For this reason, it will be difficult for perpetrators to try to disguise our voice. Voice print can be changed into digital pattern, which will be placed in the database. One risk with this system is that perpetrator may record our voice and create digitally-manipulated duplicates that can say any kind of word.
- DNA: This is probably the ultimate bio-metric technology. Each person, even identical twin, has small traces of DNA variations. DNA information can be stored in digitized format in the central database. Saliva on cigarette butts, hair brushes and hygiene products have traces of our genetic information. One real downside with DNA identification is that it will take a lab work to perform. However, there could be high performance DNA sensor in the future with automated labs inside the unit that can provide quick identification.
- Facial thermography: Each person has different facial heat signature. When seen through the IR scanner, people look unique thermally; because they have different structure of muscles, fat, cartilage and bone. The heat pattern can be used to identify someone.
