Dear Amped Tip Tuesday fellows – welcome to this week’s Tip! Today we will show you how a very simple tool, the Reverse filter, can boost your results significantly. Ok, I can hear you say: “Oh dear, how will these Amped guys fill a Tip Tuesday with such a trivial filter?”. Keep reading and you’ll find out!Continue reading
Hello, dear Tuesday Tip lovers! Hope you enjoyed your Easter eggs! But, there is still one more to open – the Amped FIVE Easter egg! Let’s see what’s inside!
Today we’re going to show you how Amped FIVE’s Snapshot functionality can speed up your work and help you reach better results.Continue reading
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.Continue reading
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.Continue reading
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.Continue reading
Hello Amped friends, welcome to this week’s Tip Tuesday! Today we’ll focus on a feature that is intrinsically part of Amped FIVE since always but is often overlooked by users. I’m talking about the possibility of changing parameters of a filter that lays at the beginning of a long chain while watching the effect on the final output. The “while” in the previous sentence is not incidental… it can save you lots of time and help you reach much better results! Let’s see what this is about.Continue reading
Welcome to this week’s Tip Tuesday! Today we are showing you an interesting, perhaps a bit hidden, functionality of Amped Authenticate. There is no need to introduce the PDF file format: it is surely the most widespread format for sharing digital documents. Therefore, it may easily happen that you have to deal with a PDF containing images and that some of them get questioned.
What would you do in such a case (after realizing that if you drag-and-drop the PDF into Amped Authenticate, nothing happens, because it’s not an image file)? Would you take a screen capture of the picture and work with that? “Nooo!” – I hope you said! Screenshots are evil for image forensics! Ok, you would get some pixels to work with, but you would lose all metadata, you would lose encoding properties, you could be recompressing data… That means you cannot check image integrity, and finding manipulations becomes much harder. No, there’s a better way of dealing with images embedded in PDFs, and we’ll show you how!Continue reading
As you smart forensic analysts have undoubtedly noticed, last week there was no Tip Tuesday. Did we forget? Well, not really… We just realized that no Tip could stand the bright light shone by last Tuesday’s great announcement: the launch of Amped Replay, Amped Software’s newest solution for investigators and frontline officers! If you happened to miss that news read more about it here!
After that, you can enjoy this week’s Tip Tuesday!
If you are working in the digital forensic field, you are certainly aware of the importance of data integrity. Ensuring data integrity means to verify that the information you are working on remains unaltered during the whole process (including transmission and storage of data).
Unfortunately, when it comes to digital images and videos, integrity is more threatened than with other types of files. For example, if you rotate an image using your OS default photo viewer and then close it, the file will likely be overwritten without any advice. While in many cases the changes made to pixels may be “negligible”, the file will still change… which means its hash value will be different. And we know this could invalidate your whole analysis (in the end, another analyst cannot know why the hash is different, it’s just different).
At Amped, we take data integrity very seriously. Our software never overwrites nor moves the evidence file you are working with. But there’s more:
Amped FIVE provides you with a seamless way of checking data integrity straight inside your project. And this Tuesday’s Tip tells you how!
Dear Amped friends, welcome to this week’s Tip Tuesday!
In our last Tip we’ve talked about how Amped FIVE users can save time by trimming and cropping the video they’re working on, so to focus the analysis only on interesting parts. Probably, we opted for that topic because February is the shortest month, and it may give you the feeling that time flows away too quickly. Since we can’t stop time, let’s at least save it when possible!
This week is Amped Authenticate‘s turn, so let’s see how we can save time when investigating our digital images. Once more, it’s a matter of focus: to save time, we have to focus the analysis on the right images (i.e., properly select them) and run only the analysis filters that we need on them. We will focus on the first aspect today, and leave the second for a coming-soon Tip.Continue reading
