IACSIT International Journal of Engineering and Technology, Vol.2, No.3, June 2010 ISSN: 1793-8236 313 1 Abstract —With the rapid advancements in information and communication technology in the world, crimes committed are becoming technically intensive. When crimes committed use digital devices, forensic examiners have to adopt practical frameworks and methods to recover data for analysis which can pose as evidence. Data Generation, Data Warehousing and Data Mining, are the three essential features involved in the investigation process. This paper proposes a unique way of generating, storing and analyzing data, retrieved from digital devices which pose as evidence in forensic analysis. A statistical approach is used in validating the reliability of the pre-processed data. This work proposes a practical framework for digital forensics on flash drives. Index Terms —Digital Forensic, Flash Drive, Framework, Data Preprocessing. I. I NTRODUCTION The digital world has penetrated every aspect of today’s generation, both in the space of human life and mind, not even sparing the criminal sphere of the world. According to Jim Christy, Director of Cyber Crime Institute, forensic science is the application of science to legal process and therefore against crime. It relates the use of science and technology, in the process of investigation and establishment of facts or evidence in the court of law [1]. When crime is aided by or involves the use of digital device(s), the investigation is categorized under digital forensic or cyber forensic. If the digital device involved is only a computer or digital storage medium, we refer to the investigation as computer forensic. Computer forensic (aka digital forensic) is a branch of forensic science, whose goal is to explain the current state of the digital artifact[14]. The pool of digital devices used by individuals – for work or for entertainment, on a day-to-day basis, includes cellular phones, laptops, personal digital assistants (PDAs), personal computers, wireless phones, wired landlines, Veena H Bhat, is a research scholar, at University Visvesvaraya College of Engineering, Bangalore University, Bangalore.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
