Internet Usage Analysis Using Karl Pearson's Coefficient of Correlation - A Computer Forensic Investigation

Internet has caused the distribution of illegal materials globally making criminal activity tracing difficult in the digital investigation process. In comparison to other types of forensic investigation, computer forensic examination comprises a large volume of digital data. Along with that the rapid evolution of digital technology and complexity of the devices being involved has made the criminal investigation further harder. In this paper we have used Karl Pearsons coefficient of correlation to extend our previous work to study the relationship between the estimated and predicted variables to justify the misuse of Internet for illegal activities. The prediction using correlation analysis can further simplify the digital investigation process by eliminating the conflicting information and gathering the digital evidence to be used as an expert testimony in the court of law.
