AN OVERVIEW OF BIOMETRIC ATMs WHY ? CONVENTIONAL ATMs -> BIOMETRIC ATMs Environmental Concerns Security Concerns ENVIRONMENTAL CONCERNS In conventional ATMs – PIN is needed PIN comes in an envelope which contains 2 sheets of paper and between this sheets secret code is marked RBI report says – 25000 new accounts are opened daily On yearly basis, a lot of paper is required – leads to cutting of trees SECURITY CONCERNS Anybody holding the card with PIN number known can operate No need to be the original owner of the card In Bio metric only the original card holder can operate BIO METRIC ATMs Biometrics refers to the automatic identification of a person based on his physiological/behavioral characteristics. Various types of biometric systems are being used for real time identification;most popular are based on face recognition and finger print matching. WHY USE IT? Traditional methods involving passwords and PIN numbers Biometrics highest level of security TYPOLOGY OF IDENTIFICATION METHODS Characteristics Physiological Behavioral Face Fingerprint Hand Eye Signature Voice Keystroke BIOMETRIC SYSTEM Data Collection Transmission Signal Processing Data Storage Decision BIOMETRIC SYSTEM VARIOUS BIOMETRIC SYSTEMS 1. HAND The three dimensional shape of a person’s hand has several advantages as an identification device. Scanning a hand and producing a result takes 1.2seconds.It requires little space for data storage about 9 bytes which can fit easily magnetic strip credit cards. 2. FINGER PRINT Most of the work in biometrics identification has gone into the finger print for general security and access control application fingerprints are gaining popularity. IMAGE ACQUISITON OTHER TOOLS 3. FACE 4. EYE RETINA IRIS 5. SPEECH MULTIBIOMETRICS 1. INTEGRATING FACES AND FINGER PRINTS FOR PERSONAL IDENTIFICATION An automatic personal identification system based on fingerprints or faces is often not able to meet the system performance requirements. MULTIBIOMETRICS 2. A MULTIMODEL BIOMETRIC SYSTEM USING FINGERPRINT, FACE AND SPEECH This system takes the advantage of the capabilities of each individual biometric. It can be used to overcome some of the limitations of a single biometrics. CONCLUSION A range of biometric systems are in developments or on the market because no one system meets all needs. The trade off in developing these systems involve component cost, reliability, discomfort in using a device, the amount of data needed and other factors. But the application of advanced digital techniques has made the job possible. Further experiments are going all over the world.
