Advanced Mobile Device Analysis Using JTAG and Chip Off

Forensic analysis on mobile devices is becoming more complicated as the device developers in their attempts to prevent data leakage add OS based protection or data encryption. This presents signifi cant challenges to the forensics examiners and investigators.
