FINGER PRINT BASED ATM SYSTEM

ATM innovation paralleled the growth of the PC and telecommunications industries.Each machine operated in a local mode without any connection to the banking

systems, and transaction authorization took place based on the information recordedin the magnetic bands of the cards. The next step in the evolution of this industry

was to connect these devices to the banks centralized systems; by then, mid-1980s, banks would work in a dual modality, in other words, the ATM would work on

-line but in the event of communication loss it had the ability to authorize thetransaction with the information recorded on the magnetic band.

In the early 90s, taking advantage of the technological boom inmicrocomputers and communications, ATMs started to work exclusively on-lineimplying that, if the ATM loss communication with its central system, there would notbe service. Once ATMs were connected directly, the need arose to protect theinformation in the card and the clients PIN (Personal Identification Number) found inmessages that had to travel across public telecommunication lines.Biometric Technology

The term biometrics comes from the word bio (life) and metric (measurement).

Biometric equipment has the capability to measure, codify, compare, store, transmit,and/or recognize a specific characteristic of a person with a high level of precisionand trustworthiness. Biometric technology is based on the scientific fact that thereare certain characteristics of living forms that are unique and not repetitive for eachindividual; these characteristics represent the only technically viable alternative topositively identify a person without the use of other forms of identification moresusceptible to fraudulent behavior.

Biometric identification is utilized to verify a persons identity by measuring digitallycertain human characteristics and comparing those measurements with those thathave been stored in a template for that same person. Templates can be stored atthe biometric device, the institutions database, a users smart card, or a TrustedThird Party (TTP) Service Providers database. Where database storage is more

economic than plastic cards, the method tends to lack public acceptance; however,Polemi (1997) found that TTPs can provide the confidence that this method is missingby managing the templates in a trustful way.

Here we are trying to develop an ATM system based on finger print.Here the system will do all the work of an ATM and will identify a person and theperson can do all transactions based on the finger print only.
