5. Definition
Forensic Science is the application of science
to criminal and civil laws and involves the
preservation, identification, extraction and
documentation for evidentiary and root cause
analysis.
6. History of Computer Forensics
• It is difficult to pinpoint when computer forensics history began.
• Most experts agree that the field of computer forensics began to evolve more
than 30 years ago.
• The field began in the United States, in large part, when law enforcement and
military investigators started seeing criminals get technical.
8. Digital Evidence
• Definition
Digital evidence is defined as information and data of value to an
investigation that is stored on, received or transmitted by an electronic device.
•Properties
i. Admissible
ii. Authentic
iii. Complete
iv. Reliable
v. Believable
9. Where to Find It?
Computer
Devices
Visited Websites Encrypted
Memory Devices
Social Media
10. Analyzing Evidences
• Latent fingerprints and impressions which develops
latent fingerprints; analyzes and compares fingerprints,
footwear and tire impressions; and runs fingerprints
through the Automated Fingerprint Identification System.
• The trace evidence department runs GSR analysis,
and identifies and compares samples of soil, glass,
fibers and paint.
11. •The chemistry section conducts analysis and comparison of illicit drugs, explosives and
unknown chemicals.
•The computer crimes team recovers evidence from computers and performs computer
enhancement on audio or video evidence.
•The medical section include Serology and DNA,
which conducts body fluid analysis, including DNA
analysis for blood stains, semen and hair for
identification and comparison.
12. Catching Criminals

status of computers, storage media, other electronic
devices, and traditional evidence.
29. Presentation
Evidence will be accepted in court on:
Manner of presentation
Qualification of the presenter
Credibility of the process used to
preserve and analyze evidence
31. Forensic Laboratories in Pakistan
NFSA (National Forensic Science Agency)
The agency provides forensic services, training and guidance to Law Enforcement
Agencies (LEAs), Government departments and Forensic bodies.
PFSA (Punjab Forensic Science Agency)
Receives physical evidence from Law Enforcement Agencies on criminal and civil
cases and analyzing the forensic evidence.
40. Disadvantages of
Computer Forensics
Costs
Preserving electronic records & preserving
them is extremely costly.
Presents the potential for exposing privileged
documents.
Legal practitioners must have extensive
computer knowledge.
41. Conclusion
With computers becoming more and more involved in our everyday life, both
professionally and socially, there is a need for computer forensic. This field will
enable crucial electronic evidence to be found whether it was lost, deleted,
damaged or hidden, and used to prosecute individuals that believe they have
successfully beaten the system.
