The research introduces a structured and consistent approach for digital forensic investigation. Digital forensic science provides tools, techniques and scientifically proven methods that can be used to acquire and analyze digital evidence. The digital forensic investigation must be retrieved to obtain the evidence that will be accepted in the court. This research focuses on a structured and consistent approach to digital forensic investigation. This research aims at identifying activities that facilitate and improves digital forensic investigation process. Existing digital forensic framework will be reviewed and then the analysis will be compiled. The result from the evaluation will produce a new model to improve the whole investigation process.

Due to the large amount of information produced, accumulated, and distributed via electronic means, it is necessary for forensic experts during crime investigation to increase their abilities to search for important evidence in a timely manner because this is essential to the success of digital forensic examinations. The inadequacy of resources both in tools and human and also limitation in time have a negative impact in result obtained during digital forensic investigation. Previous researchers state that the chances of success in criminal prosecution by law enforcement agencies depend heavily on the availability of strong evidence. The coming out of intelligent software agents that function autonomously with little or no human intervention during crime investigation is significant to the success of digital forensic investigation. Better use of tools is necessary, beyond the capabilities of the currently used forensic tools. In this paper, we discuss the usefulness of intelligent software agent in digital forensic. The goal of the paper is to provide a better knowledge and understand the concepts of intelligent software agent in digital forensic. The findings presents in this paper came from thoroughly review of previous digital forensic literature.

Abstract-Digital forensic science provides tools, techniques and scientifically proven methods that can be used to acquire and analyze digital evidence. There is a need for law enforcement agencies, government and private organisations to invest in the advancement and development of digital forensic technologies. Such an investment could potentially allow new forensic techniques to be developed more frequently. This research identifies techniques that can facilitates the process of digital forensic investigation, therefore allowing digital investigators to utilize less time and fewer resources. In this paper, we identify the Visual Basic Integrated Development Environment as an environment that provides set of rich features which are likely to be required for developing tools that can assist digital investigators during digital forensic investigation. Establishing a user friendly interface and identifying structures and consistent processes for digital forensic investigation has been a major component of this research.
