Multimedia Applications in Forensics, Security and Intelligence
Published in Abid Hussain, Garima Tyagi, Sheng-Lung Peng, IoT and AI Technologies for Sustainable Living, 2023
The process of gathering, reviewing, and reporting on digital evidence in order to make it admissible in court is known as computer forensics. To establish a plausible case, forensic investigators must retrieve the probative evidence from the machines involved. The second step is Multimedia Forensics, in which analytical techniques are used to analyze the contents.

Auditing IT security on a regular basisA compliance assessment to see that a company has a well-thought-out security strategy in place and is following it. For example, if a policy requires all users to update their passwords every 30 days, the audit must examine how well the policy is followed. The audit should also look at who has access to specific applications and records, as well as the extent of authority that each individual has. It’s not uncommon for an investigation to find that so many people have access to sensitive information and too many people have skills beyond what they need to do their work. A successful audit will provide a list of issues that need to be corrected in order to ensure compliance with the security policies.Computer Forensics or digital forensics is the study of how computers can be used to solve crimes. Digital forensics is a discipline that incorporates aspects of law and computer science to classify, obtain, analyze, and protect data from computer systems, networks, and storage devices in such a way that the data are preserved in their integrity and admissible as evidence in a court of law. In relation to a criminal case or civil action, a data forensics investigation can be launched. It can also be used to retrace measures taken when data are missing, to quantify harm after a computer incident, to examine the unlawful leakage of personal or organizational sensitive data, or to validate or determine the effects of industrial espionage, among other things. Successfully combating cyber fraud in a court of law requires proper treatment of a computer forensics case. A data forensics investigator’s status in a court of law is also enhanced by rigorous experience and qualifications. Electronic forensics certifications include the CISSP (Certified Information Systems Security Professional), CCE (Certified Computer Examiner), CSFA (CyberSecurity Forensic Analyst), and GCFA (Global Computer Forensic Analyst; Global Information Assurance Certification Certified Forensics Analyst). Experts who have learned computer investigative techniques as well as the use of Guidance Software’s incase computer forensics tools are certified as EnCE Certified Examiners. Computer forensics degrees are available from a variety of institutions (both online and traditional). Accounting, especially auditing, preparation should be included in those degree programs, as it is very helpful in fraud investigations. A digital forensics expert must be familiar with the different rules that govern the collection of criminal evidence.
LDPC Codes and Digital Forensics – A Perspective Approach
Published in IETE Journal of Research, 2022
Computer forensics deal with the investigation of computer crime pertaining to legal evidence found in computers and digital storage media. The interdisciplinary field of Computer forensics is Computational criminology which defines criminology concepts and generates solutions for the complex phenomena, using the back-up thrust of quantitative approach of computing science methods relating to Computational forensics (CF). The research investigation and problem definition methods of Computer forensics span over computer-based modeling, simulation, and analysis based on pattern evidences, such as tool marks, fingerprints, shoe prints, documents, DNA patterns, digital evidence, and crime scenes. One of the Computational methods is the definition and establishment of likelihood ratio (LR) that can be applied in the forensic sciences to increase the efficiency and effectiveness of forensic casework.
