Advanced recognition techniques have made use of human aspects that are difficult to tamper with. These advanced biometric identification devices use individualistic characteristics into account for recognizing an individual for his/her true identity. Some of these intrinsic characteristics are iris, fingerprint, face, voice, retina etc.The earlier methods of biometric security also included writing and hand geometry but these methods are slowly becoming obsolete since they can be altered and manipulated.
Nowadays, one of the most widely used and commonly found biometric devices is the fingerprint recognition system. It is a known fact, with various studies dedicated to it, that each individual has a different set of fingerprint mark. It is also inexpensive and fast to access the finger print and ascertain the true identity of the person. It is also used at the time of criminal investigations and time attendance systems in workplaces. The advanced fingerprint technology uses sensor technology and optical systems to capture high quality prints. The images are very fine and are according to Federal Information Processing Standard 201 for personal identification (FIPS 201/PIV). Making biometric devices traceable, new age biometric security has a unique serial number. This makes it appropriate for government and high profile uses.
The other type of biometric device is iris scanner that works by capturing the image of the iris in the eye. This method of identification, verification and recognition is one of the most fool proof systems to ensure that no outsider is able to get access inside the restricted areas. Iris scanners do not involve a high beam laser that can penetrate the eye or is discomforting. It involves a video based technology that captures the image of the eye. It is safe and uses infrared rays only.
As contrary to biometric devices such as fingerprint scanners fingerprint scanners, iris scanners do not involve any touch. They are considered to be more hygienic and are more secure. It is one of the most advanced technologies today.
Biometric security has a variety of applications and is widely accepted as an element to ensure greater security. Both the biometric devices are easy to adapt and can be added to any system or application. Not only do they save time but are also a great addition to maintain control and security.
