recognition are required. Describes four attributes that characterize a biometric (8 marks)
b) Distinguish between genotypic and phenotypic characteristics in biometrics (4 marks)
c) The use of biometrics raises various public concerns over privacy of biometric data. Discuss atleast
five privacy issues raised regarding biometrics. (5 marks)
d) In what regard are behavioral characteristics more vulnerable to changes (4 marks)
e) When biometrics systems are used for identification or authentication there are four possible
outcomes. Identify these outcomes (4 marks )
f) Using a diagram illustrates the biometrics authentication process (5 marks)

QUESTION TWO
a) In authentication, possession of a chip card combined with biometric methods may further increase
reliability. Discuss atleast five advantages of using a combination of chip card and biometrics.
(10 marks)
b) Biometrics is an identification technology widely used in physical access control and forensics.
Cryptography is the science for information security. People generally agreed that biometric
information needs to be protected with cryptography. Discuss the benefits of biometrics and
cryptography (10 marks)
QUESTION THREE
a) Esoteric biometric systems provide a selection of some of the more obscure techniques. Describe at
least five types of these biometric modalities (10 marks)
b) Discuss the different levels of fusion that are applied in multimodal biometric systems.
(10 marks)
QUESTION FOUR
a) In order for the biometrics to be ultra-secure and to provide more-than-average accuracy, more then
one form of biometric identification is required. Hence the need arises for the use of multimodal
biometrics. Your client is considering this option to secure their data bank. You are have been
asked to to prepare a report that will help them in decision making. As part of your report discuss
the following issues
i) The benefits of multimodal biometrics (5marks)
ii) Issues considered in the design of Multimodal Systems (10Marks)
iii) Which biometric modalities to fuse (5 Marks)
QUESTION FIVE
a) As any other system and technology the biometric technology has its vulnerabilities. As a security
expert in biometrics you have been requested to prepare a presentation on attacks on biometric
authentication system for your colleagues. Describe three types of attacks that you shall include in
your presentation (8 marks)
b) Using the fingerprint scanning discuss how the “zoo” concept can be used in Setting variable matching threshold (12 marks)
