DIGITAL EVIDENCEAbstract
Cybercrimes are committed but due to lack of professional investigation and
follow up of providing digital evidence, the case become weak. Unfortunately,
there is a insufficiency of information about the crime related to computer is, and
how to conduct digital evidence based investigation. A comprehensive guideline
and framework to computer forensic investigators and analysts is missing for
Bangladesh. Therefore, there is a need for a proper digital evidence based crime scene investigation framework of processes to prevent Cybercrime in Bangladesh.
The study started with the investigation of presently available investigation
process using Digital Evidence Management Framework (DEMF) in Bangladesh,
check whether any legally accepted DEMF exists in Bangladesh or not, reviewed
available DEMF in literature and formulate a generally accepted DEMF with digital
evidence so as to safeguard from cybercrime in Bangladesh. Reviewing fourteen
different Digital Evidence based Investigation Process, consulting crime scene
investigators and forensic experts from CID and PBI, Law Makers of Cyber Act,
and White Hackers- a well-defined DEMF involving seven phases is proposed.
The Phases were Initiation process, Planning, Collection and Preservation or Data
Acquisition, Examination and Analysis, Closing, Post Processes or Disseminating
the case and finally quality management. Four different types of cybercrimes like
Hacking, Identity Theft, Cyber Fraud and Phishing were taken out of numerous
types of cybercrimes. Gaps within the existing law and involvements of white
hackers are identified. Major problems of DEMF were identified for a proper
digital evidence based crime scene investigation framework of processes to
safeguard Cybercrime in Bangladesh.
