Computer forensics is a very important branch of computer science in relation to computer and Internet related crimes. Earlier, computers were only used to produce data but now it has expanded to all devices related to digital data. The goal of Computer forensics is to perform crime investigations by using evidence from digital data to find who was the responsible for that particular crime.
For better research and investigation, developers have created many computer forensics tools. Police departments and investigation agencies select the tools based on various factors including budget and available experts on the team.
Forensic science is a scientific method of gathering and examining information about the past which is then used in the court of law. Digital Forensics is the use of scientifically derived and proven methods toward the preservation, collection, validation, identification, analysis, interpretation, documentation, and presentation of digital evidence derived from digital devices for the purpose of facilitation or furthering the reconstruction of events found to be criminal, or helping to anticipate unauthorized actions shown to be disruptive to planned operations.

Low Cost Visual Support System for Challenged PeopleChristo Ananth
Christo Ananth, Stalin Jacob, Jenifer Darling Rosita, MS Muthuraman, T Ananth Kumar, “Low Cost Visual Support System for Challenged People”, 2022 International Conference on Smart Technologies and Systems for Next Generation Computing (ICSTSN), 978-1-6654-2111-9/22, IEEE, 10.1109/ICSTSN53084.2022.9761312, March 2022,pp. 1-4.
Description:
Christo Ananth et al. emphasized that people who are visually impaired have a hard time navigating their surroundings, recognizing objects, and avoiding hazards on their own since they do not know what is going on in their immediate surroundings. We have devised a new method of delivering assistance to people who are blind in their quest to improve their vision. An affordable, compact, and easy-to-use Raspberry Pi 3 Model B+ was chosen to demonstrate how the proposed prototype works. All of this is made possible by a camera and sensors and the most modern image processing algorithmic methods available. A camera and ultrasonic sensors are utilized to measure the distance between the user and the object. Using a global positioning system (GPS), it is also possible to track down people who are blind or have impaired vision (GPS). Consider the possibility of making this a for-profit product. Small and light, it may be fitted to a regular pair of spectacles without incurring additional fees or posing any further difficulties.

A computer is an electronic device that can process and store data. It is made up of various hardware components, such as a central processing unit (CPU), memory, storage devices, input/output devices, and communication interfaces.
The CPU is the brain of the computer and performs most of the processing tasks. It retrieves data from memory, performs calculations, and executes instructions. Memory, also known as RAM (Random Access Memory), is used to store data and instructions temporarily while they are being processed by the CPU.

2. Overview
What is Data Recovery?
How can it be used?
Techniques
Recovery Methods
Secure Deletion
What can you do?
3. What is data recovery?
Retrieving deleted/inaccessible data from electronic
storage media (hard drives, removable media,
optical devices, etc...) is called as Data recovery.
Typical causes of loss include:
Electro-mechanical Failure
Natural Disaster
Computer Virus
Data Corruption
Computer Crime
Human Error
4. Cases of Recovery
FIRE
Found after a fire
destroyed a 100 year old
home – All data
Recovered
CRUSHED
A bus runs over a laptop
– All data recovered
SOAKED
PowerBook trapped
underwater for two
days – All data
recovered
5. What is Data Loss?
Data has accidentally been erased or data control structures
have been overwritten.
Data has been corrupted or made inaccessible.
Data is unable to be accessed from a previous functioning
computer system or backup.
6. What Causes Data Loss?
Sabotage(Destroy or Damage)
Natural Disaster
Hardware Error
Virus Attack
Human Error
Intentional deletion
Accidental overwriting of files
Software Corruption
8. Facts of Data Recovery
The majority of data loss situations are recoverable.
Computer storage systems may fail, but the data stored
on them is not always completely lost.
There are occasions when damage to data is permanent
and complete data recovery is not possible. However,
some data is usually always recoverable.
Data recovery professionals can recover data from
crashed hard drives, operating systems, storage devices,
servers, desktops, and laptops using various proprietary
data recovery tools and techniques.
10. Software Data Extraction
Data extraction is the process of moving data
off of the imaged drive to another destination
location.
Data extraction software scans sectors of the
hard drive and restructures the file system either
in memory or another hard drive.
The software can be used to copy the
recoverable data to a destination location.
11. Data Recovery
The user may send a failed hard disk drive to a
private data recovery company that offers
secure and confidential data recovery.
The data recovery company will carefully
perform part replacement of the heads, spindle
motor and base casting, the electronics board,
etc. in a clean room environment.
Part replacement has historically been
successful for data recovery about 40%-60% of
the time.
12. Data Recovery Techniques :
Scanning Probe Microscopy
(SPM)
A technique that is used to image and measure surfaces at
the atomic level.
Scans an atomically sharp probe over a surface which
produces a 3D topographic image of the surface at the
atomic scale.
13. Data Recovery Techniques
Magnetic Force
Microscopy (MFM)
MFM (Magnetic Force Microscopy) is a new
technique which images the spatial variation of
magnetic forces on a sample surface.
MFM is derived from scanning probe
microscopy (SPM) and uses a sharp magnetic
tip attached to a flexible cantilever for analysis.
An image of the field at the surface is formed
by moving the tip across the surface and
measuring the force.
14. Magnetic Force Microscopy (MFM)
Detectable old data will be present beside new data on the track
which is usually ignored.
Together with software, MFM can see past various kinds of data
loss/removal.
Each track contains an image of everything ever written to it, but
each layer gets progressively smaller the earlier it was written.
15. Magnetic Force Microscopy (MFM)
MFM looks at the minute sampling region to detect remnant
magnetization at track edges.
17. Scanning Tunneling Microscopy
(STM)
STM (Scanning Tunneling Microscopy) is a more
recent variation of MFM which uses a probe tip
typically made by plating nickel onto a pre-
patterned surface.
The probe is scanned across the surface that is to
be analyzed. STM measures a weak electrical
current flowing between the tip and the sample.
The image is then generated in the same way as
MFM.
18. Summary
Individuals or companies may experience data loss
at any time for many reasons.
There are various steps that should be implemented
to help prevent data loss.
Data loss can be very costly and very upsetting.
There are several data recovery techniques that
have proven to be successful or partially successful
in recovering data.
Utilizing qualified professional data recovery
specialists will aid in the degree of success of data
recovery.
