News stories extolling the successful use of DNA to solve crimes abound.
In all, DNA technology is increasingly vital to ensuring accuracy and fairness in the criminal justice system. By the same token, DNA can be used to clear suspects and exonerate persons mistakenly accused or convicted of crimes. DNA can be used to identify criminals with incredible accuracy when biological evidence exists. The past decade has seen great advances in a powerful criminal justice tool: deoxyribonucleic acid, or DNA. This thesis is focusing on JTAG and ISP physical acquisitions techniques.TOC | Executive Summary | Using DNA to Protect the Innocent USING DNA TO SOLVE CRIMES These techniques were created from manufactures to test PCBs and repair devices but they are being used as a forensic technique to acquire the data from a device. The aim is to give an overview of these techniques from a forensic point of view and in addition to some other tests will try to prove that are forensically equivalent to any other method. The first test will focus on showing the differences on the different types of acquisition by comparing the results of a forensic analysis of the same device using Cellebrite UFED Touch and Physical Analyzer. The second test will try to prove that all physical acquisitions are equivalent by comparing the acquired data from the same device with two different methods.
