1. The document discusses adding biometric identification, specifically eye recognition, to ATMs to improve security over traditional passwords. 2. It describes how an ATM with eye recognition would work, prompting the user to insert their card then input their PIN before capturing an image of the user's eye to verify their identity. 3. Eye recognition offers advantages over other biometrics for ATM use as the iris and retina patterns are unique, stable over a person's lifetime, and can be imaged from a distance. However, challenges include obtaining a clear image of the small eye target.

3. ABOUT THEATM:-
3
1 An ATM is an electronic device which allows a bank’s
customer to make cash withdrawals and check their
account balance at any time without the need for a human
teller.
2.. In ATM system customers authenticate themselves by
using a plastic card with a magnetic stripe which is known
as “ATM CARD”.
3. The magnetic stripe encodes the customers account
number and a numeric password which is known as PIN
(Personal Identification Number) .

4. HOW ATMWORKS:-
4
1. Physical access card and PIN or other
password is used in order to access a
customer’s account
2. TheATM prompts the user to insert the card.
3. When the card is entered the customer
personal identification number (PIN) is
requested.

5. 4. The customer inputs his or herPIN.
5. If the card is a valid card which can be
processed by the machine then control transfer to
next stages and prompts the user to withdrawalof
cash.
6. If the number entered incorrectly several times in a
row most ATMswill retain the card as a security
precaution to prevent an unauthorized users.
7. ATMreads and store customer’s data on a smart
card.

6. ATM Frauds
6
• ATM’s are manifold due to the exponential
growth of “intelligent” criminals dayto day.
• Now a days Frauds are easily taping the
passwords of card holder.

7. Draw backs of PIN:-
7
1 The PIN does not prove the identification of
the cardholder.
2 People write PINs and disclose to others
increasing the risk of fraud; and PINs can
be stolen by observation.
3 ATM systems today use no more than an
access card and PIN for identityverification.

8. 4 There is an urgent need for improving
security in banking region.
5 So we need more security confirmation in
ATMs

9. Biometrics with ATM:-
9
•Biometric techniques gives high security to
avoid fraudulent use ofATMs

10. HOW ATM WORKS WITH BIOMETRICS
(AN ATM WITH AN EYE):-
1. TheATMprompts the user to insertthe card.
2. When the card is entered the customeris
personal identification number(PIN)
requested.
3. The customer inputs his or herPIN.
4. When PIN matches the accountthen
an ordinary video camera captures an image of
the customer's right or lefteye.
10

11. 5 This image is converted
into a digital code, which
is compared with one
already stored for that
individual if the system
perceives a match, the
customer can proceed the
user to withdrawal of
cash.
11

12. 6 When a match is made with PIN but not the
images, the bank could limit transactions in
manner agreed upon by the customer when
the account was opened,and could store the
image of the user for later examination by
the bank officials.
7. ATM reads and store customer’s data on a
smart card.

13. Eye Recognition:-
13
• Iris:
– Measures the shape & color of
the Iris
• Minutiae rich
• Inconvenient
• Expensive
• Retina:
– Blood Vessel Pattern The blood
vessels at the back of the eye
have a unique pattern, from eye
to eye and person to person.
• Highly Accurate
• Low public acceptance .

15. Advantages
15
• Highly protected, internal organ of the eye.
• Externally visible; patterns imaged from a
distance.
• Iris patterns possess a high degree of
randomness.
• Changing pupil size confirms natural physiology
• Limited genetic penetrance of iris patterns
• Patterns apparently stable throughout life.
• Encoding and decision-making are tractable.

16. Disadvantages:-
16
• Small target (1 cm) to acquire from a
distance (1 m).
• Moving target ...within another.
• Located behind a curved, wet, reflecting
• Surface.
• Obscured by eyelashes, lenses, reflections.
• Partially occluded by eyelids, often drooping.
• Deforms non-elastically as pupil changes size.
• Illumination should not be visible or bright
Some negative (Orwellian) connotations.

17. CONCLUSION:
17
• Thus this typeof developed ATM is more
reliable in providing security by using facial
recognition software by keeping the time
elapsed in the verification process to a
negligible amount we even try to maintain the
effiency of ATM system to a greater degree.
