Biometric Identification

Biometric Identification BIOMETRIC IDENTIFICATIONIntroductionThe escalating threat of global act of terrorism and narcoterrorism in the twenty-first century has generated massive changes in the acknowledgment of suspect criminals. One of the technological highlights in this regard has been biometric identification. Biometrics refers to the science of identifying humans organism by analyzing biological traits or physical characteristics (Bolle, 2004). This paper describes the some astray- utilize forms of biometric identification and demos the advantages and disadvantages of each.Advantages and Disadvantages of Biometric Systems Biometric identification is an automated manner used to recognize a person based on behavioral or physiological characteristics (Tipton Krause, 2004). behavioral characteristics include utterance or authorisewriting. Physiological characteristics include fingerprint, iris, or hand geometry.1. Fingerprint analysis The most commonly known biometric system is a the fingerprint analysis (Bolle, 2004). The principle here is that each individuals set of fingerprints is unique. This method requires a user to wander his or her finger onto a testifyer. The persons fingerprint is scanned and sent to a database where it will be compared, identified, and verified. Fingerprint engine room is widely used today in law enforcement, banking, and in merchandising. The biggest strength of this method is its high truth and number 1 incidence of turned acceptance and its low cost. However, fingerprint technology is said to have a high false rejection rate (where valid users are incorrectly rejected access). Sometimes, the technology does non recognize accurately in case of hand trauma, age, or disease.2. overhaul geometry The hand geometry identification method is the second most commonly used biometric tool (Jain, Ross, Pradhakar, 2004). Basically, it analyzes finger length and the edge of a hand. Hand biometric requires a person to p lace his or her hand on the wile which has pegs to cast the hand on. When the hand is put properly in place, the device scans and checks the database for identification or verification. While the hand biometric device is easy to integrate, use, and can correct work despite dirty hands, the technology is expensive, has low accuracy level, cannot read when hand is injured or has suffered from trauma, or when a person has arthritis.3. Retina technologyThe concept is that it is practically impossible to counterfeit a human retina. The digital scanner analyzes capillary vessels situate in the back of the eye. Retina biometrics requires the person to place his or her eye close to a scanner and as the device scans, to focus on a specific point while being still (Jain, Ross, Pradhakar, 2004). The process takes 10-15 minutes. Retina technology has a very high accuracy rate. However, it is a sensitive process, expensive, and quite uncomfortable for those who wear glasses.4. theatrical r ole technology office biometrics analyzes the pitch or tone of a persons voice. Voice biometrics fall into two categories voice recognition and speech recognition. Voice recognition analyzes quality of the voice while speech recognition interprets what a person says (Jain, Ross, Pradhakar, 2004). The advantages of this system is that is it non-invasive and not susceptible to error due to a cold. However, its accuracy may be compromised with the presence of acoustics in the room and change magnitude age.ConclusionBiometric identification includes methods such as fingerprint technology, hand geometry, retina analysis, and voice recognition. Although biometric identification is undeniably cutting edge technology, there are disadvantages present that is inherent with any modern technological systems.ReferencesBolle, R. (2004).
