SETTING 3D PASSWORD !!
 The 3D password presents
a virtual environment
containing various virtual
objects
 The user walks through
the environment and
interacts with the objects
using navigators
 The password is a 5

Flexibility
Strength
Ease to Memorize
Respect of Privacy

The 3D password’s main application
domains are protecting critical systems and
resources.
 Critical Servers
 Nuclear Reactors & military Facilities
 Airplanes and missile Guiding

1. Holography (from the
Greek, whole + write) is the science
of producing holograms invented
by Dennis Gabor
2. It is an advanced form of
photography that allows an image to
be recorded in three dimensions
3. The technique of holography can 16

I. AUTHENTICATION : Hologram
stickers cannot be scanned or
photocopied so they are used in
authentication of passports
,books etc.
II. ATTRACTIVE : Hologram stickers
can also used in packing as they

# For trade-show
booths
# Museums display

 Binocular
vision is
dependable on
the distance
between our
eyes
 Each eye sees
22

 The brain takes
the information
from each eye
and combines
them into one
image
 Difference of
angles makes
23

 Anaglyph
 Pulfrich
 Polarized
24

 On the screen
,two images one
blue and one red
is displayed
 The lenses only
let one image 25

 Polarized lenses are
both a gray color and
let color through
 The lenses are
specially cut at
opposing 45 degrees
 Two images are
projected on the
screen and each one 26

 The polarized
glasses allow
only one of the
images into
each eye
because each
lens has a
different 27

 These glasses use the
concept of one dark and
one light lens to form 3D
images
 The image through the
dark lens reaches the
brain slightly after the
image that went through 28

CONCLUSION AND FUTURE SCOPE
1)3-D Password setting is a very useful technology
for the areas where high security risk is involved
2)3-D tattoos and street art has capacity to
capture the market of advertisement industry
3)3-D printing has a great future scope for
example NASA engineers are printing 3-D
printing parts, which are structurally stronger and
more reliable than conventionally crafted parts,
for its space launch system. Use in medicine:
jaw transplant , to grow new human tissue with
the help of bio printer
