Hello dear Amped Blog readers, welcome to this week’s Tip Tuesday. Today we’ll be dealing with one of the most sneaky kinds of fakes: recaptured images. A recaptured image is a “picture of a picture”: you display your (possibly forged) image on a screen, or you print it on paper, and then you take a picture of it. This apparently naive approach is much more clever than it seems: the obtained image will be a “camera original” image to all extents, so it will likely pass every test based on metadata/format analysis. Are we left alone against this subtle threat? Of course not, Amped Authenticate is here to help. Let’s find out how.
Hi Amped Blog readers, welcome to this week’s Tuesday Tip! Although we do our best to make you love our Amped FIVE, we are still aware that you may have better things to do in your life than enhancing videos… so, what really makes us happy is to help you get the job done in the least amount of time! That’s why this week we’ll focus on how Amped FIVE’s Motion Detection filter can save you lots of time during triage.
April Fools’ Day has just passed and we hope you didn’t go through any nasty trick! Alas, for people working with digital evidence, the risk of getting fooled by some ambiguous finding is always around the corner. In the case of digital image forensics, among the most frequent pitfalls, we find false positives produced by forgery localization algorithms (that is, when an algorithm marks as manipulated a region that was not so). Today’s Tuesday Tip deals with them and shows how Amped Authenticate helps you rule out some of them.
