I. FORMAL INTRODUCTION

Human factors are considered in computer security systems.

The weakest link is regarded as the weakest link. There are, however, three

major domains in which human-computer interaction is used

Operations relating to security The main emphasis is on the in this case.

The difficulty is one of the most serious issues that could arise.

Human authentication techniques are classified as follows:

Authentication can be further subdivided into the following categories:

1) A technique based on recall that requires the user to

Recreate or repeat a previously created secret.

One common example of recall-based authentication is
