Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

to enroll for the donor request from the application itself. If the admin wish to make user
a registered donor, with some of the formalities with the organization it can be done.
Specialization of this application is that the user will not have to register on sign-in for
searching the blood banks and blood donors it can be just done by installing the
application to the mobile.
The purpose of making this application is to save the user’s time for searching blood of
needed blood group during the time of the emergency.
This is an android application developed in Java and XML with the connectivity of
SQLite database. This application will provide most of basic functionality required for an
emergency time application. All the details of Blood banks and Blood donors are stored
in the database i.e. SQLite.
This application allowed the user to get all the information regarding blood banks and
blood donors such as Name, Number, Address, Blood Group, rather than searching it on
the different websites and wasting the precious time. This application is effective and
user friendly.

Crime Scenes
Physical Crime Scenes vs. Cyber/Digital
Crime Scenes
Overlapping principals
The basics of criminalistics are constant
across both physical and cyber/digital
Locard’s Principle applies
• “When a person commits a crime something is
always left at the scene of the crime that was not
present when the person arrived”
16. 16
Digital Crime Scene
Digital Evidence
• Digital data that establish that a crime has been
committed, can provide a link between a crime and
its victim, or can provide a link between a crime and
the perpetrator (Carrier & Spafford, 2003)
Digital Crime Scene
• The electronic environment where digital evidence
can potentially exist (Rogers, 2005)
• Primary & Secondary Digital Scene(s) as well
17. 17
Forensic Principles
Digital/ Electronic evidence is extremely volatile!
Once the evidence is contaminated it cannot be de-
contaminated!
The courts acceptance is based on the best
evidence principle
• With computer data, printouts or other output readable
by sight, and bit stream copies adhere to this principle.
Chain of Custody is crucial
18. 18
Cyber Forensic Principles
• The 6 Principles are:
1. When dealing with digital evidence, all of the general forensic and
procedural principles must be applied.
2. Upon seizing digital evidence, actions taken should not change that
evidence.
3. When it is necessary for a person to access original digital evidence,
that person should be trained for the purpose.
4. All activity relating to the seizure, access, storage or transfer of digital
evidence must be fully documented, preserved and available for
review.
5. An Individual is responsible for all actions taken with respect to digital
evidence whilst the digital evidence is in their possession.
6. Any agency, which is responsible for seizing, accessing, storing or
transferring digital evidence is responsible for compliance with these
principles.
20. 20
Identification
The first step is identifying
evidence and potential containers
of evidence
More difficult than it sounds
Small scale devices
Non-traditional storage media
Multiple possible crime scenes
22. 22
Identification
Context of the investigation is very
important
Do not operate in a vacuum!
Do not overlook non-electronic
sources of evidence
Manuals, papers, printouts, etc.
23. 23
Collection
Care must be taken to minimize
contamination
Collect or seize the system(s)
Create forensic image
Live or Static?
Do you own the system
What does your policy say?
26. 26
Collection: Documentation
• Take detailed photos and notes of the computer / monitor
• If the computer is “on”, take photos of what is displayed on the monitor – DO
NOT ALTER THE SCENE
28. 28
• Rule of Thumb: make 2 copies and don’t
work from the original (if possible)
• A file copy does not recover all data areas of
the device for examination
• Working from a duplicate image
• Preserves the original evidence
• Prevents inadvertent alteration of original evidence
during examination
• Allows recreation of the duplicate image if
necessary
Collection: Imaging
31. 31
Collection: Imaging
Forensic Copies (Bitstream)
Bit for Bit copying captures all the data on the copied
media including hidden and residual data (e.g., slack
space, swap, residue, unused space, deleted files etc.)
Often the “smoking gun” is found in the residual
data.
Imaging from a disk (drive) to a file is becoming the
norm
Multiple cases stored on same media
No risk of data leakage from underlying media
Remember avoid working for original
Use a write blocker even when examining a copy!
32. 32
Imaging: Authenticity & Integrity
•How do we demonstrate that the image is a true unaltered copy
of the original?
-Hashing (MD5, SHA 256)
•A mathematical algorithm that produces a unique value (128 Bit,
512 Bit)
• Can be performed on various types of data (files, partitions, physical
drive)
•The value can be used to demonstrate the integrity of your data
• Changes made to data will result in a different value
•The same process can be used to demonstrate the image has not
changed from time-1 to time-n
33. 33
Examination
Higher level look at the file system representation of the data
on the media
Verify integrity of image
• MD5, SHA1 etc.
Recover deleted files & folders
Determine keyword list
• What are you searching for
Determine time lines
• What is the timezone setting of the suspect system
• What time frame is of importance
• Graphical representation is very useful
34. 34
Examination
Examine directory
tree
• What looks out of place
• Stego tools installed
• Evidence Scrubbers
Perform keyword
searches
• Indexed
• Slack & unallocated
space
Search for relevant
evidence types
• Hash sets can be useful
• Graphics
• Spreadsheets
• Hacking tools
• Etc.
Look for the obvious
first
When is enough
enough??
35. Issues
lack of certification for tools
Lack of standards
lack of certification for professionals
lack of understanding by Judiciary
lack of curriculum accreditation
Rapid changes in technology!
Immature Scientific Discipline

On board:
preservation, collection, validation, identification, analysis, interpretation, documentation and presentation
List on the board.
What are the important components?
Application of laws very NB. Discuss this.
Why are these so importnat
Never do anything that might inadvertently cause something to be written to the suspect’s original media.
Whether analyzed on site or taken to the lab, it is essential to protect the integrity of the data.
A duplicate image, also known as a bit-copy, image, or clone, is an exact, bit-for-bit copy of the source media.
A duplicate image of a physical device will be a true, digital copy of the entire physical device, including partition tables, reserved areas, partitions and unused areas of the device.
A duplicate image of a logical drive will be a bit-for-bit copy of the original logical drive, including Boot Record, FATs, Root Directory, Data Area, and Partition Slack.
Developed in 1994, MD5 is a one-way hash algorithm that takes any length of data and produces a 128 bit value, that is a “fingerprint” or “message digest”. This value is “non-reversible”; it is “computationally infeasible” to determine the data based on the value. This means someone cannot figure out your data based on its MD5 value. Here is an example of a MD5 output for the data area:
Processing Data Area: sectors 3246-1648013
MD5 Checksum for: Data Area = 945df74c54de310690e17487d6203876
The actual value is 945df74c54de310690e17487d6203876
A mathematical algorithm was applied to the "Data area" to produce the value (to learn the mathematical details about the algorithm, check out RFC 1321 at http://www.cis.ohio-state.edu/rfc/rfc1321.txt.) Every time an MD5 hash is performed on the data area, it should result in the exact same value. If a different value is obtained, then the data area has been altered.

Definitions
Hash — A hash value (or simply hash) is a number generated from a string of data. The hash is substantially smaller than the data itself, and is generated by a formula in such a way that it is extremely unlikely that some other data will produce the same hash value.
One-way hash function — An algorithm that turns data into a fixed string of digits, usually for security or data management purposes. The "one way" means that it's nearly impossible to derive the original data from the string.
Message Digest (MD) — The representation of data in the form of a single string of digits, created using a formula called a one-way hash function.
Algorithm — A formula or set of steps for solving a particular problem. To be an algorithm, a set of rules must be unambiguous and have a clear stopping point.
