Here is a List of Digital Forensics Terms for Lawyers to Learn

Digital forensics is purely technical in nature, and when attorneys deal with the same, they need to work with some digital evidence. Hence, Elijaht computer forensics has compiled a list of most essential technical concepts in digital forensics and how they are associated with attorneys.

  1. Verified Forensic Image

It is a certain type of copy of all the contents of a flash drive, hard drive etc. Instead of just copying the files, a forensic image copies all the binary values that represent the information, visible as well as invisible on a target drive. A forensic examiner verifies the forensic image to be exactly same as the original which is referred to as hash value. Attorneys should be concerned about these verified image because it preserves the original evidence if there is any need for carrying out any forensic analysis further and until it is created, we cannot ensure that the info on the hard drive cannot be modified. You need a verified forensic image created so as to carry a digital forensic analysis.

  1. Hash Value

Has value is a unique identifier that validates a forensic image that is an exact copy of an image. Any hard drive or digital file is a set of binary numbers at the core. The professionals use a special algorithm to create a numeric code which is called a hash value that is exceptional to the exact binary sets on a specific drive. If a single 0 or 1 is changed, then the hash value is totally changed as well.

  1. Write Blocker

It is a special component of hardware that forensic examiners use in order to access digital evidence without changing it. If you are connected to a flash drive, hard drive etc., it becomes risky for your computer’s OS as it may makes changes to your drive as well. This risk can be eliminated by using a write blocker. Ensure that you always use a write blocker or else it may destroy the digital evidence rather than securing it.

  1. JTAG / Chip-Off Forensics

These methods are used for accessing digital evidence on mobile devices, particularly when the device is damaged or is locked by a password. They need very specific equipment and not many labs are specialized to do the same. Attorneys should be concerned about these methods as they are the only way to recover digital evidence from a cell phone that is ruined or locked by password.
