Skyfi Labs Biometric Authentication Project
- 1. Biometric Authentication Finger Print Based Access Control Copyright © 2015 Skyfi Education Labs Pvt. Ltd.
- 2. Introduction to Biometrics The term "biometrics" is derived from the Greek words “Bio" means life and “Metric" means to measure. Biometrics is the measurement and statistical analysis of people's physical and behavioral characteristics. © 2015 Skyfi Education Labs Pvt. Ltd.
- 3. Introduction to Biometrics The technology is mainly used for identification and access control or for identifying individuals that are under surveillance. The basic premise of biometric authentication is that everyone is unique and an individual can be identified by his or her intrinsic physical or behavioral traits. For example, every human has an unique fingerprint, DNA, iris etc. © 2015 Skyfi Education Labs Pvt. Ltd.
- 4. Types of biometric identifiers Physiological characteristics: The shape or composition of the body. Finger Print DNA Face Recognition Iris Recognition © 2015 Skyfi Education Labs Pvt. Ltd.
- 5. Types of biometric identifiers Behavioral characteristics: The behavior of a person. Typing Rhythm Gesture Voice Recognition © 2015 Skyfi Education Labs Pvt. Ltd.

- 7. Human Finger Print A fingerprint is an impression left by the friction ridges of a human finger. These are detailed, presumed to be nearly unique, difficult to alter and durable over the life of an individual, making them suitable as long-term markers of human identity. A fingerprint consists of ridges and valleys and they provide grip for our hand. © 2015 Skyfi Education Labs Pvt. Ltd.
- 8. Finger Print Patterns The three basic patterns of fingerprint ridges are Arch Loop Whorl Scientists have found that family members often share the same general fingerprint patterns, leading to the belief that these patterns are inherited. © 2015 Skyfi Education Labs Pvt. Ltd.
- 9. Finger Print Recognition Finger Print Recognition requires the comparison of several features of the print pattern. These include patterns, which are aggregate characteristics of ridges, and minutia points, which are unique features found within the patterns.

- 10. Finger Print Sensor A fingerprint sensor is an electronic device used to capture a digital image of the fingerprint pattern. The captured image is called a live scan. This live scan is digitally processed to create a biometric template (a collection of extracted features) which is stored and used for matching. © 2015 Skyfi Education Labs Pvt. Ltd.
- 11. Types of Finger Print Sensor Capacitive Optical RF Thermal Piezo resistive Ultrasonic Piezoelectric MEMS © 2015 Skyfi Education Labs Pvt. Ltd. Capacitive and Optical type finger print are the most commonly used one.

- 13. Function of Biometric System Sensor: it is the input unit may contain scanner, camera, microphone etc to capture the identification. Pre Processor : this involve in filtering the useful data from the measured quantity. Extractor: this will extract the necessary features that need to be identified. © 2015 Skyfi Education Labs Pvt. Ltd.
- 14. Function of Biometric System Template Generator: based on the extracted features the template will be made as a digits or an image. Those templates will be stored in a data base only during enrollment process. Matcher: during the matching phase the stored templates will be compared with the input data using various algorithms. © 2015 Skyfi Education Labs Pvt. Ltd.
- 15. Application of Biometrics India's national ID program called Aadhaar is the largest biometric database in the world. As of 31 December 2015, over 95 crore (950 million) Aadhaar numbers have been issued in the project. © 2015 Skyfi Education Labs Pvt. Ltd.

Editor's Notes
- Every human has some unique features of their own. Those uniqueness is measured for security applications known as biometric techniques. The parameter may be a physical appearance or else the behavior.
- Biometric is classified into two types: Physical and behavioral characteristics. Physical characteristics are the unique feature in human body as shown.
- In This method the behavior of a people is used as an identification.
- arch: The ridges enter from one side of the finger, rise in the center forming an arc, and then exit the other side of the finger. loop: The ridges enter from one side of a finger, form a curve, and then exit on that same side. whorl: Ridges form circularly around a central point on the finger.
- The ridge ending is the point at which a ridge terminates. Bifurcations are points at which a single ridge splits into two ridges. Short ridges (or dots) are ridges which are significantly shorter than the average ridge length on the fingerprint.
- It is the basic schematic of all kind of biometric system. The sensor is the input unit may contain scanner, camera, microphone etc to capture the identification. Pre processing involve in filtering the useful data from the measured quantity.
