A Framework for Digital Forensic Investigation using Authentication Technique to maintain Evidence Integrity

Digital evidence is information stored or transmitted in binary form that may be relied in an investigation. Digital evidence is the core for any digital forensic investigation that takes many forms and can be found in several places. It is the evidence on which whole investigation travel and reach to an exact conclusion. Ultimately we can say that any a little bit of alteration with collected data could impact to final result, which would be extremely dangerous to grab an innocent one. In this research work we proposed a framework that covers space to lead an investigation and will keep behind all possible jeopardizes action by achieving evidence integrity associated with evidence classification and to make use of chain of custody in an appropriate position.
