Evidence Verification Complications With Solid-State Drives, Ryne Teague, Michael Black
Journal of Digital Forensics, Security and Law
Solid-state drives operate on a combination of technologies that create a barrier between the physical data being written and the digital forensics investigator. This barrier prevents the application of evidence verification methods developed for magnetic disk drives because the barrier prevents the investigator from directly controlling and therefore verifying that the underlying physical data has not been manipulated. The purpose of this research is to identify a period of inactivity where the underlying physical data is not being manipulated by wear leveling or garbage collection routines such that evidence can be reliably verified with existing hashing algorithms. An experiment is …

Forensic Cell Site Analysis: A Validation & Error Mitigation Methodology, John B. Minor

The E911 Initiative in the mid-1990s established an opportunity to obtain location specific digital evidence of subscriber activity from cellular carriers. Call Detail Records (CDR) containing Cell Site Location Information (CSLI) evidence production was made available from cellular carriers in response to the CALEA, 911 and ECPA acts. In the late 1990s, cellular carriers began to produce evidence for investigative and litigation purposes. CDR/CSLI evidence has become an important evidentiary focus in the courtroom. This research project resulted in the creation of a method of validating cellular carrier records accuracy and mitigating errors in forensic cell site analyst conclusions. The …
