Biometrics.

Biometrics applies to a broad range of electronic techniques that employ the human physical characteristics as means of authentication. Nowadays, this technique is getting more recognition in the security domain because the old password systems are becoming more and more vulnerable to hackers. Biometric techniques make use of an individual’s distinct biological characteristics to provide a Bio-Password that is almost impossible to break by any traditional hacking method. Usage of Biometric authentication is often used in combination with other mechanical techniques to give robust protection to a system. Some examples of Biometric techniques are:

• Facial Thermogram: In this case, the heat signature of an individual is captured using an Infrared device and stored into a database from which a person’s facial identity can be recognized by the same machine and can be used (in future) for recognition.
• Fingerprint: No two human beings have the same finger impression in this world. Based on this conception, Biometric technique is often implemented. The line pattern on a finger (often the thumb) is recorded using an optical or infrared scanner and stored for future identification.
• Hand Geometry: This technique is based on the assumption that every person has a different hand shape. It also assumes that after a certain age, an individual’s hand shape does not change significantly. This method measures length of fingers and/ or thumb, hand’s width etc. that are used in future to categorize a person.
• Retinal Scan: Retinal Scan technology is based on the blood vessel pattern in the eye retina. When a retinal image is captured, an Infrared light source illuminates the retina to create a pattern.

The identifying power and utility of Biometric Techniques depend on FRR (False Rejection Rate) and FAR (False Acceptance Rate). FRR gives the measure of rejection of identification of a valid identity and FAR counts the rate of wrong acceptance of an invalid identification. So, to combine both FRR and FAR, biometric devices commonly include features which have variable threshold or sensitivity settings. These sometimes facilitate FRR and sometimes FAR, tailored to the importance of the secured system.
Like other powerful technologies, Biometrics too has disadvantages. First of all, if an individual’s Biometric identity is changed by some accident, the user will face problems. Also, in case of a malicious intervention, one runs the risk of losing his/ her life as Biometric Techniques are related to human lives.

Pictures of some IT Godfathers

1) Tim Berners Lee — Founder of the World Wide Web

 2) Bjarne Stroustrup – founder of C++, Stroustrup called his new language ‘C with Classes’ and then ‘new C’.Because of which the original C began to be called ‘old C’ which was

considered insulting to the C community. At this time Rick Mascitti suggested the name C++ as a successor to C.

3) Michael Dell of Dell Computers

4) James Gosling of Sun Microsystems – Father of Java. Java was originally called Oak by creator James Gosling, from the tree that stood outside his window, the programming team had to look for a substitute as there was no other language with the same name. Java was selected from a list of suggestions. It came from the name of the coffee that the programmers drank.

7) Steve Woznaik(sitting) and Steve Jobs of APPLE Computers Favorite fruit of founder Steve Jobs. He was three months late in filing a name for the business, and he threatened to call his company Apple Computers if the other colleagues didn’t suggest a better name by 5 o’clo ck
