This document discusses biometrics, which uses physical and behavioral characteristics to identify individuals. It outlines various biometric technologies including fingerprints, palm prints, iris scans, retina scans, voice recognition, signatures, and keystrokes. The biometric process involves data collection, template generation, matching, and decision making. Benefits of biometrics include strong security, accountability, convenience, and reduced password administration costs.

- 13. RETINA GEOMETRY TECHNOLOGY A retinal scan involves the use of a low- intensity coherent light source, which is projected onto the retina to illuminate the blood vessels which are then photographed and analyzed. A retinal scan has an error rate of 1 in 10,000,000, compared to fingerprint identification error being sometimes as high as 1 in 500.
- 14. GAIT RECOGNITION Gait recognition is an emerging biometric technology which involves people being identified purely through the analysis of the way they walk.
- 15. VOICE RECOGNITION Voice Recognition: is the Identification using the acoustic features of speech that have been found to differ between individuals. The vocal characteristics depend on the dimensions of the vocal tract, mouth, nasal cavities and the other speech processing mechanism of the human body.

- 17. KEYSTROKE DYNAMICS Keystroke dynamics are the patterns of rhythm and timing created when a person types. Keystroke dynamics include: Overall speed Variations of speed moving between specific keys. Common errors. The length of time that keys are depressed.
- 18. BIOMETRICS Vs TRADITIONAL TECH. Which is better? Neither is adequate for strong, practical security on its own. Each has strengths and weaknesses, and real security requires some combination of these or other technologies. PASSWORD It is simple to use, easy to implement and can be reasonably strong. The problem is one of scale. BIOMETRICS The use of physical traits such as fingerprints, irises, faces or voices to identify persons is more complex, but is becoming more practical. All forms of biometrics operate on the close enough principle. Combining both is practical as well as strong.
