It’s a password reset

takes an entirely different
approach from traditional

thereby resists common
attacks.
It authenticates you by knowing what you

memory.
This is based on well known in
psychology research.
A system based on personal
preferences is also less vulnerable
to data-mining attacks than one
that relies on more easily
searchable facts.
A ssumption ? People lie to increase security then forgot. Avoid memory Use preferences. Preferences are not forgotten, change rather slowly.
The researchers, Anya Hurlbert
and Yazhu Ling of Newcastle
D rivers
University, the United Kingdom,
found that women tend to prefer
pink – or, at least a redder shade
– while men fancy blue.
Human preferences are fuzzy. (

- Economic stand
- Social stand
- Religion The popularity of Bill Clinton After
Gulf war is drastically fallen.
- Physique
- Division of labor etc
The importance of any consensus of people's likes and dislikes, and the
practical value thereof, are often obtunded by the large variances of
human hedonic behavior within and between people. RUBACKY E. P,

Human preferencesUmm. are fuzzy. (
Ambiguous !
Likes and dislike ) are largely
driven by –
- Gender
The Problem 1 -
- Age I never hard it
- Ethnicity If you don’t know
- Economic stand what is it, How can
- Social stand
- Religion you vote for it.
- Physique
- Division of labor etc

The Problem 2 -

Hence not free from data

In India those who play

In a clever experimental design,
The Problem 3 -
Marcus, et al (1995) tested the validity

subjects were given the opportunity to -Emotion, Emotion goes on

This procedure enabled subjects to

the same subjects were confronted with -Feeling

of groups that they had rated as “least-

-And these are subject to
change.
How does a person recall

Proposal – 1(a)
Proposal – 1(a) A text phrase require knowledge, but a shape is only about a feeling, emotion and thinking. The same image an American assumes a coffee mug but a Mongolian may think an ostrich egg. No matter.
Proposal – 1(b)
Design images considering
the Psychology of human
fascination about shapes and
images.
“In our studies at Leicester University of some
everyday likes and dislikes, we compared the
responses of children of various ages and of
young adults. Instead of artificially making
subjects familiar with various materials by
repeated exposures during the experiment, we
have used
objects which, for cultural reasons, are already
to varying degrees familiar to people of different
ages. We have thus investigated materials
ranging from complete novelty to extremely high The psychology of
levels of familiarity indeed.” human fancy – Andrew Colman and
Wladyslaw SlucklnProposal – 1(c)
Images are to design with
extreme care that – They should
not look visually biased.
Example- ( Don’t use )
Natures beauty Well composed Foods that
Erotic Avoid common
( sunrise, sunset images everyone prefer
( sex sells interest images
etc ) ( rule of third aka ( ice-cream )
everywhere ) like flower,
photography) children etc.
Human psychological development also involves
preferences for the familiar .Things that are easier to picture are easier to understand.
Proposal – 1(d)
Misc-
- Design images with line art, vector shape and 4-8 bit color depth.
It will also resolve accessibility issue. ( will help to reduce loading
time )
- Design Images with same style and shade in terms of patterns.
Like XP, Vista, Mac define an unique Blue moon style for showing
images.
- Using likes and dislike smiley is a very good usable approach.

proceed for now.
Later I will see.
An Overly Optimistic Attitude towards
Life Leads to a Dulling of EmotionThe success of Blue Moon authentication lies how efficiently we can optimize the ‘Somewhat like’. And ‘Don’t know’ subset area.
Future Research required 1. Duration of persistence – Human preferences. And how much shot term ( cognitive memory ) used. 2. Psychological justification for Fuzzy mathematical model ( Fuzzy set ) in terms of human preferences. How far can we hack behavioral preferences using fuzzy logic theory. ?

Simplicity is not the goal. It is the by-product of a good idea
and modest expectations.- Paul Rand
