What is Forensic Science?

Overview of Forensic Science

• Forensic science, or forensic science, is an applied science that utilizes theories and methods to assist investigative bodies in uncovering the circumstances surrounding specific events.

• It aids judges and decision-makers in issuing appropriate rulings related to crimes, extending beyond just court applications to include use within companies and institutions.

Digital Forensics: A Subfield of Forensic Science

Definition and Scope

• Digital forensics focuses exclusively on digital evidence, distinguishing it from traditional forensic practices that often involve physical evidence like blood analysis or autopsy results.

• The emergence of digital forensics stems from the evolution of daily life where digital channels have proliferated; people now heavily rely on mobile devices and computers for communication.

Changes in Evidence Collection

• The nature of crime tools has evolved; criminals can now manipulate individuals psychologically through technology, such as using deepfake images or tracking their daily lives via smartphones.

• Digital traces left behind by criminals have also changed; evidence can now be found on smartwatches, mobile phones, or social media platforms rather than solely relying on physical traces like footprints or blood.

Importance of Digital Forensics in Crime Investigation

Applications in Various Crimes

• Digital forensics plays a crucial role in investigating various types of crimes including fraud, child exploitation, terrorism, drug trafficking, and murder.

• Criminal activities such as child trafficking and drug trade increasingly occur on the dark web; thus digital footprints are vital for law enforcement agencies to track down perpetrators.
