Digital Evidence Processing
Investigators learn how to collect and preserve digital evidence, and to integrate digital evidence into a case. Additionally, investigators are exposed to the advanced tools and techniques used by the CGRCFL, so they can better understand what to expect from a forensics examination. This course requires no prerequisites, but attendees should have a working knowledge of computers.
Image Scan Training
The Federal Bureau of Investigation's (FBI) Computer Analysis Response Team (CART) developed the Image Scan system to help investigators locate the presence of picture files that may contain contraband on a computer. This system allows the investigator to view a variety of graphic formats during a consensual search, and protects valuable digital evidence by booting up a computer using the Linux operating system. After mounting the hard drive in a “read only” manner, Image Scan prompts the investigator to search for picture files only. During this process, the tool logs every step taken by the investigator, further documenting what occurred during the search process.
CART successfully completed field-testing of Image Scan in May of 2004, and has offered to make this tool available to all law enforcement personnel upon request. The North Texas RCFL in conjunction with CART's Unix Program, designed and developed Image Scan instructor training, and has educated several Examiners working at FBI-sponsored RCFLs. These individuals are the only authorized instructors/distributors of Image Scan outside of FBI Headquarters.
Law enforcement personnel that conduct on-site investigations for child pornography are encouraged to take the Image Scan training.
