Systems, methods, and computer program products for facilitating write-protected virtual access to a target computing device, wherein the use and inspection of the computer device may occur without altering the digital data thereon, are disclosed. In an aspect, a user inserts a virtualization media device, which will boot the computer system in a write-protected mode. The computing device will operate through an operating system on the target computing device and instantiate the subject computer through a virtual machine environment. Such virtualization will protect target computing device files from accidental alteration during, for example, investigatory searches of the target computing device storage device.

Forensic computer examination systems and methods

A device to read data stored on a memory device of a printed circuit board (PCB) while the memory device is installed on the PCB is disclosed, including, a microcontroller to control acquiring memory data from the memory device when a processor on the PCB is in an idle state, and a resistance measurement and signal driver to measure the resistances of the signals controlling a memory device and to read the memory data from the memory. A method and system are also disclosed.

On-board chip reader adapter (OCRA)

A method of isolating hidden data in a solid state memory system is disclosed including obtaining a logical block address (LBA) image from the memory system, obtaining a physical block address (PBA) image, determining whether an error exists in the PBA image and correcting the error, calculating an ETCRC on each sector of the LBA image and building a search tree indexed on the ETCRC value. For each sector in the PBA image, the method also includes computing an error tolerant cyclic redundancy check (ETCRC) value and searching for the ETCRC value in the LBA search tree. If the ETCRC value is found, also included is comparing the cyclic redundancy check (CRC) of the LBA and PBA sectors, and outputting to an output file the PBA sector as hidden data if either the ETCRC value is not found in the LBA search tree or the CRC comparison fails.
