Biometric ID System
Technology has progressed very far since the days of spy thrillers in the areas of access control for physical access control, computer log-in, welfare disbursement, international border crossing and national ID cards, along with financial banking online and ATM machines.
Another great advancement in the access control is in automobiles, biometrics is used in place of keys for keyless entry and keyless ignition.
Biometrics have been used in forensics for criminal identification for a long time but biometrics have not been able to be used in government applications and civilian securities.
Fingerprint scanners are used in police stations, high security buildings and even on PC keyboards these days. You can get a personal USB fingerprint scanner for around one hundred dollars and it will guard your computer with high-tech biometrics.
Biometric devices are the automatic identification of a person based on their behavioral or physiological characteristics.
Rather than using a PIN number or an ID card, the person has to physically be there and this is taking away the necessity of passwords and ID tokens or ID cards.
Biometrics will prevent unauthorized access control to ATM's, laptops, computer networks and cellular phones. PIN's and passwords can be forgotten and ID cards or tokens can be stolen, lost or forged for the biometric devices are used to enhance security and reduce financial fraud.
The most popular biometrics devices are the fingerprint, iris or face scanners and chips or the retinal scan, voice, signature and hand geometry.
The biometric devices recognize the person trying to be identified or scanned but the user has to be enrolled in the database of the biometric devices system. The data is stored in smart card or at a central database and the information is retrieved when a person needs to be identified.
The fingerprint scanners are a form of biometric devices and its job is to take the place of the human analyst by collecting a fingerprint sample and comparing it to the other samples that the database has on record.
The fingerprint scanner works in two steps and the first step is that the fingerprint scanner has to get a picture of your finger, the ridges and valleys and it compares these ridges and valleys of the fingerprint to see which one it matches of the database of ridges and valleys in pre-scanned images.
There are two fingerprint scanners in the biometric devices category and they are capacitance scanner and optical scanner. The optical scanner uses a light sensor system like the digital camera to capture the ridges and valleys of the fingerprints. The capacitance scanner uses a electrical current to sense the ridges and valleys of the fingerprints.
These two are great ways to identify the fingerprints and identities of an individual. These fingerprint scanners or other biometric devices can be used to verify customers during transactions that are performed over the telephone or internet.
The International Civil Aviation Organization is allowing the use of E-passports. E-passports are passports that contain chips that have the holder’s facial image and other traits. E-passports are such great biometric devices because they help protect against increased security threats.
