Cyber Forensics Tools: A Review on Mechanism and Emerging Challenges
(IEEE, 2021-05-18) Fernando, V
With the development of technology, "Data", also interpreted as "Information" has become a major role played in the field of Cyber Forensics. One of the most crucial incidents which needs data to be important is, when it is taken as evidence in cyber-crimes. These crimes can be occurring in the fields of digital media and network in many instances related to crime scenes. Crime and forensic both investigators need the help of digital forensics to investigate in order to identify, whether the victim has committed a crime or not. Therefore, it is a requirement for an investigator to use a suitable, accurate, affordable and a reliable cyber forensic tool for the forensics investigations conducted with respect to crimes. Many researchers have done experiments on different functionalities, a forensic tool should have and have come up with various tools specifically for each branch in cyber forensics. Furthermore, with time, these cyber forensic tools have been identified with drawbacks due to the invasion of crimes, especially related to the sophisticated technology expansion. Therefore, the acquiring process of forensics tools is in lack of advanced features to detect evidence. This paper describes on some timely Digital Forensics tools and discusses emerging challenges in advanced areas of Digital Forensics.

Digital Forensic Investigation Framework for Marine Industry
(IEEE, 2022-07-18) Fernando, V; Senarathne, A
A massive 400% increase of cyber-attacks was reported in the Marine industry since February 2020 up to date. Experiments and research are being conducted towards safeguarding data in various technological aspects of the marine environment with regards to navigation, transportation and system management. At present, generic investigation processes are developed for computer incidents and forensic readiness in this sector, but those do not describe the investigation process precisely. Although there are incident analysis technologies implemented for the Marine environment, it lacks reliable digital forensic tools for evidence extraction and analysis. Therefore, in this research, a comprehensive digital forensic investigation framework is proposed, answering the issues of existing frameworks, and a tool is implemented for the examination of navigational evidence. Forensic procedures of existing investigation methodologies were taken into consideration when developing the fusion framework. The Marine Geo Navigator was implemented with the technologies of Machine Learning and Visualization to evaluate geolocations and paths of vessels. Through expert analysis, the proposed investigation framework was verified as a suitable process to be utilized in the Marine industry and the tool was validated resulting an acceptable level of accuracy.

Tool to Extract and Summarize Methodologies of Research Articles for Visually Impaired Researchers
(IEEE, 2019-12-05) Amarawansha, K; Dasanayaka, D; Rajapaksa, C; Fernando, V; Thelijjagoda, S
With the development of technology, not only the university students but also visually impaired students have also started engaging in higher studies and research. They have started using electronic documents comprehensively for their studies. However, some components of electronic documents are also in a difficult state to be referred as per their complexity. This paper has introduced an application to identify such components and to summarize the research methodology section of Information Technology related research papers including the flow charts and graphs. The requirements of visually impaired students in research were identified and the paper has introduced a system to help these students by summarizing methodologies of a given paper within a very short period of time accurately in the document form and in voice. The methods such as machine learning, Information extraction and natural language processing were mainly applied to bring the solution out. Currently available applications were thoroughly observed and this concept was introduced with several features that are lacking in the existing solutions. The results were observed via visually impaired researches with their consent on the support provided by the output.

VEHlA: Safety enhancement of non-premium vehicle assisting system for personal vehicle users
(IEEE, 2021-01-20) Manamperi, V; Liyaarachchi, K; Samaranayake, S; Fernando, V; Abeygunawardhana, P. K. W; De Silva, R
“Vehia” is a personal vehicle driving assistant which renders a massive support to the driver while drive the vehicle. As it is already known that, humans have great relationship with the automobiles since the innovation of the first wheel in stone age era. As a result of the development of the technology many vehicle manufacturing industries were established. In current society, there are many modern cars with tremendous features in it like, Mercedes, BMW, Audi, Tesla etc. Those cars are highly technical and even higher in price. Majority of the people are not affordable on buying those vehicles since the middle range vehicles are not capable of much features like, visualizing performance, driver safety etc. “Vehia” is a device with a multi-informative display which can easily connect to the vehicle that supports the driver in many ways. This device is basically reducing the discrimination of high-tech cars and the middle range cars. So, it provisions utmost same feeling which can gain by an advanced high price car to the driver via a middle range vehicle. This device increases the driver safety by various features like giving alerts and consists with a smartphone based mobile application to interconnect with the mechanics in case of troubleshooting.
