Design and implementation of digital forensic process model for effective crime investigation in Nigeria

We are currently in an era of information, where digital devices and electronic communication have led to a high level of interconnectivity. These devices have become an essential part of our daily lives, and as a result, are often involved in criminal activities, making traditional crime investigation methods ineffective. The solution to this problem is a digital forensic model, which is required for effective crime investigation. Although there are already existing models globally, they are not specific to Nigeria's investigation process. Therefore, this work is focused on developing a digital forensic model based on Nigeria's investigation process and existing laws. This model is then implemented in software. The software has been analyzed and designed using the Object-Oriented Analysis and Design Methodology (OOADM).
