@upstreamdatainc @spencerschille I am always in absolute awe of the amalgamation of tech being deployed in both processes and final product when you share these videos.

@upstreamdatainc @spencerschille I think it would be cool to explain a little bit about the manufacturing process.

Why did Ian Whiffin agree to give expert testimony on Jen McCabe’s cellphone extraction, when the state refused to let him look at or even give him the full, original extraction OR its verification hash? A thread🧵 Full cellphone extractions, sometimes called forensic images, generate what’s called a “hash value”, which serves as a unique digital fingerprint necessary for ensuring the integrity of data. Any discrepancy between the hash values indicates tampering with or corruption of evidence, alerting forensic examiners to potential issues with the evidence. Hash verification is a fundamental principle and a rather ubiquitous practice in the world of digital forensics, where data validation and verification are key. It is the gold standard across the industry, and has also become so in the courtroom, whereby admissibility of digital evidence is determined by its relevance, authenticity and reliability. In court, the hash value can be used to demonstrate that the evidence has not been altered since its collection, and is a universal way for experts to authenticate and validate the reliability of data for the trial Court. But, an extraction that’s missing a hash value altogether is a huge red flag. 🚩 Who removed the hash value? And why? It’s necessary to the chain of custody, and as Gaurino and Tully would be well aware, it’s also an element of the data that an expert would require in order to verify and validate it. There’s no “good” reason for why someone would remove a hash value, and the extraction can’t be characterized as a forensic image as its origin is unknown. This was a deliberate step taken to hide something, which one could argue shows consciousness of guilt. If the data are true and accurate, why would you bring their integrity into question by removing the hash? However, if the data were altered or tampered with, and let’s say, hypothetically speaking, you wanted a digital forensic expert to provide testimony supportive of your “Google search” theory. . . In that hypothetical, you’d have to remove the hash value. Otherwise, the expert would immediately detect that the data were altered, as they would not be able to verify the hash against the original. #KarenReadTrial #JusticeForJohnOKeefe #FreeKarenRead #CantonCoverup #PoliceCorruption #KarenRead #Cellebrite #DFIR
