Holographic technology allows for three-dimensional data storage by using lasers and photosensitive materials to record holograms. Dennis Gabor invented holography in 1947 by using coherent light to record the phase of an object. A hologram is reconstructed by exposing the photosensitive recording material to the original reference beam without the original object. Holographic data storage can achieve extremely high densities and uses spatial light modulators and interference patterns within holographic materials to store and retrieve data in parallel as light is diffracted off volume gratings. Potential applications include high-capacity data storage, medical imaging, virtual reality, and more.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Essentials of Automations: The Art of Triggers and Actions in FME
Holographic data Storage
1.
2. Devices that use light to store and read
have been the backbone of data storage
for almost three decades.
CDs revolutionized data storage in
1980s followed by an improved version
of CDs, DVD, around 1997.
CDs and DVDs are the primary storage
media for music, software, personal
computing and video.
3.
A CD can hold approximately 783
megabytes of data whereas a doublesided, double-layered DVD can hold up
to 15.9GB of data.
4. Although conventional storage mediums meet
today's storage needs, storage technologies have to
evolve to keep pace with increasing consumer
demands.
Today’s user requires such storage media that
provides faster data access ,huge storage capacity
but in a small package. To achieve this, scientists
are now working on a new optical storage method
called “Holographic Memory”.
5. Polaroid scientist Pieter J. vanHeerden
first proposed the idea of holographic
storage in the 1960s.
The Defence Advanced Research
Projects Agency (DARPA) and high-tech
giants IBM and Lucent's Bell Labs have
led the resurgence of holographic
memory development.
6.
Holographic Data Storage is an
advanced data storage concept that
stores information in the form of
holographic images.
Holographic Data Storage is a
volumetric approach of storing data.
An HDSS can store 1-4 TB of data on a
sugar-cube sized crystal.
7.
The technology uses holograms which
are created when a light from a single
laser beam is split into two beams.
8.
Uses a reference beam and a data beam
to create an interference pattern.
While writing :
The intersection of the two beams causes a
change, which is then stored.
While reading:
Action of the reference beam and
interference pattern is used to recreate the
data beam.
12. •
•
•
Blue-green argon laser is split into two
beams.
One is known as the object or signal
beam, and the other as the reference
beam.
Interference pattern created by these
two beams creates hologram.
13. •
•
•
SLM is a 1024 * 1024 array of light or
dark squares.
The array represents the data to be
stored, and is usually implemented by a
set of pixels on an LCD.
An SLM can be refreshed at rates of
about 1000 frames per second.
14. It is used to allow the laser beam to access
different pages in the hologram.
• Two types of multiplexing is used- shift and
angular multiplexing.
• Shift multiplexing uses a rotating disc to vary
the angle of laser beam so as to access a
different view of the hologram, used in reading
data.
• Angular multiplexing uses mirrors to change the
angle at which the laser strikes the crystal, used
in recording data.
•
15. •
There are mainly two storage mediums
used:
• Lithium-niobate crystal, and
• Photopolymer.
16. •
•
•
•
CCD is an array of sensors which corresponds to
the pixels on the SLM.
The CCD is used to read the interference pattern
from the reference beam, and also to read the
information from the hologram.
The matrix construction of the CCD allows it to
read1Mb data at once.
Typical CCD dimensions are one square
centimeter, and typical access rates are 1000
frames / second, or 1 Gigabit / second.
17. When the blue-green argon laser is fired, a beam
splitters creates two beams.
The object or signal beam travels straight and
bounces off one mirror and travels straight
through SLM(Spatial-Light Modulator).
The signal beam passes through a SLM, that
stores pages of raw binary data.
The information from the page is carried by the
signal beam to light-sensitive lithium-niobate
crystal.
18. the reference beam shoots out the side of beam
splitters and takes a separate path to the
crystal.
When the two beams meet ,the interference
pattern created stores the data in a specific area
in the crystal.
19.
20.
HDS contains information using an optical
interference pattern within a thick, photosensitive
optical material.
Light from a single beam is divided into two separate
optical patterns of dark and light pixels.
By adjusting the reference beam angle, wavelength, or
media position, a multitude of holograms can be
stored on a single volume.
21.
The stored data is read through the reproduction of
the same reference beam used to create the hologram.
The reference beam’s light is focused on the
photosensitive material, illuminating the appropriate
interference pattern, the light diffracts on the
interference pattern, and projects the pattern onto a
detector.
22.
The detector is capable of reading the data in parallel,
over one million bits at once, resulting in the fast data
transfer rate.
Files on the holographic drive can be accessed in less
than 0.2 seconds.
23. ¤

The word Hologram is derived from a Greek
word “holos” meaning whole and “gram”
meaning message.
A hologram contains the information about
size, shape, brightness and contrast of object
being recorded.
It is a 3-D image formed by the interference of
light beams from a laser or other coherent
light source.
24. Amplitude and phase modulation
holograms
Volume holograms
Transmission and reflection holograms
25. Increased storage capacity
Increase read/write speed due to
parallel access.
Longer storage life
Security
26. The challenge is to find the right
recording material-a photosensitive
substance that is both stable and cheap
enough to use commercially.
Problems with parallel recording.
Cross-talk noise, as it is known, causes
faint images all of the files recorded to
be called up even when only one is
being accessed.
27. Spatial light modulators in a low cost
system.
Holographic recording is also very data
sensitive. You have to keep the data
streaming. It’s not appropriate for
partial recordings.
28. The future of holographic memory is very promising.
The holographic storage provide high data density. It
can easily store 1000GB of data in a small cubic
centimeter crystal reducing the cost on the other hand.
It may offer high data transfer rate.
But even then the holographic way of storing data is
still at the base stage and it may take another couple
of years for this technique to hit desktop with a real life
data storage solution.
However this technology itself is dazzling and aims to
light up the desktop experienences.
