Understanding how online services change images

During a recent workshop on image authentication, I ran a few practical sessions. One concentrated on the changes that online services and social media platforms make to the images that we upload. It turned out to be an interesting experiment that has had some structured research over the past few years.

These are excellent starting resources when developing any internal Standard Operating Procedure:

A Classification Engine for Image Ballistics of Social Data: https://arxiv.org/abs/1610.06347

A Forensic Analysis of Images on Online Social Networks: http://ieeexplore.ieee.org/abstract/document/6132891/

Why is this important?

Amped FIVE Update 9223: New Hikvision Loader, New Tool, New Functions

It’s a crazy busy time here at Amped Software, but that doesn’t stop development. Yes, it’s time for another update to Amped FIVE.

The craziness has meant that I have been a little quiet on here and I apologize for that. I really enjoy reaching out to you via the medium of this blog, so I do feel it when I don’t have the time to do so. Conferences, training, workshops, seminars and exhibitions—it’s fantastic that more and more people are seeing how Amped Authenticate, Amped DVRConv, and Amped FIVE can help them solve their video and image challenges.

With this latest update to Amped FIVE, more help is available today!

Let’s start things off with a big one! One that we have been working on for a while and one that shows the true power of partnerships really working…

Is that image authentic?

With digital images, people are starting to ask the question – “is it authentic?”

My first digital camera was probably around 1997/8 – that’s nearly 20 years ago! It was a Canon and stored its tiny images on a CF Card. It was pretty heavy and bulky, but a huge step up from the first Kodak prototypes of the 1970’s.

Those had to store an image onto a cassette tape!

In 1990, a few years before my first adventures into digital imaging, Adobe released Photoshop for the Mac.

Take a look at the digital photography timeline to learn more:

This little trip down memory lane has revealed that for over 25 years, people have been able to easily capture and edit digital images. We have reached a point where high-quality images can be captured quickly, edited, and then shared within a few clicks of a mouse or taps on a screen. It’s no wonder then, that during this digital generation, people have also learned how easy it is to change that picture for unlawful reasons.

You are, most likely, from within the investigative community, so you can probably think of many different reasons why someone would want to, ‘tell a different story’. A digital image can be manipulated to reinforce that story, and up until now, many people have trusted that image as being a true and accurate representation.

Advanced File Information – A Closer Look!

In the recent Amped FIVE Update (Rev. 9010), there were some big additions to the advanced “File Info”.

The updated tool has already received high praise from regular users who can now do all their frame, stream, hex and format analysis from within the same application – Amped FIVE!

It’s time therefore to take a much closer look at this new and powerful functionality.

Amped FIVE Update 9010 Part 2: Filter Updates and Interface Enhancements… too much for one post!

Amped FIVE Update 9010 continues…this is the second post relating to our very big Amped FIVE update launched a few days ago. In case you missed Part 1, click here.

Filter Updates

Measure 3d

When setting a reference measurement, the most common mistake is to get your line in the wrong direction! This then reverses the measure result.

Under the “Reference” tab, we have made things easy for you.

Amped FIVE Update 9010 Part 1: Resize 1:1, Perspective Aligner, Block Difference, Frame Analysis

Many months of filter development and product expansion have resulted in a very big update to Amped FIVE!

As a result, we created two blog posts on this update. This is the first post. The second will come soon…

I have said it before, and I’ll say it to you again now… most of these development ideas have come from you, the user. If you suggest an idea, it goes onto the list. That list drives the updates. We are committed to providing you with the most advanced software for all of your needs in image and video forensics.

New Filters

Resize 1:1

Calibrating an object to a known scale is important in fingerprint, footwear mark and other analysis and comparison tasks. “Resize 1:1”, located under the “Edit” category, now enables you to use the scale shown in the image to present the image at the actual size.

Training – We also come to you!

Many of you will have seen the recent Amped Training schedule, detailing some of the training events at our HQ in Trieste, Italy, and also at the Henderson training facility in the USA.

As we mentioned, we also come to you… and this is important in a number of ways.

Forensic Video Analysis and the enhancement of Digital Images and Video, is a relatively small sector in Forensic Science. However, the input, (the amount of product being acquired), and the output, (the amount of images and video presented as evidence), is huge.

As a result, those people doing the job are very, very busy people… but if you are one of those people – you don’t need us to tell you that!

At Amped Software, we understand this. That’s why, whenever possible – we will come to you… wherever you are!

Amped DVRConv: The Beginner’s Guide

Simplicity, speed, and forensic integrity all come together in Amped’s latest software, providing law enforcement and digital forensic labs with a quick and easy stand-alone solution to the challenge of video conversion.

It’s been a few months since its release, so hopefully by now, you will have seen the blog posts and press releases regarding Amped DVRConv. It is a very easy program to use…it really is. You tell the application that you have a video file that you cannot play, the software analyzes the file and format, and then it gives you a video file that you can play in any standard playback software, along with the conversion log for full disclosure.

How do you tell it? That’s easy as well. You either use drag and drop, copy and paste, or even have it ‘watch’ a specific folder and then convert immediately.

Amped Authenticate Update 8782: Enhanced PRNU, LCD Recapture Detection and many more filter improvements

At Amped Software we are continually researching new methods to help you in your analysis. Designing, testing and then implementing new features and filters is a continuous process. When complete, we get these out to you as soon as we can.

In this post, I will be introducing you to some of the latest developments in Amped Authenticate.

For those new to this blog, or the software, Amped Authenticate is a software package that enables you to conduct forensic image authentication and tamper detection on digital photos and documents. Today, digital images are key sources of evidence in criminal activities. But the creation and manipulation of those images is relatively easy to do, so it is vitally important that images being used as evidence are what they say they are. Amped Authenticate is the only software in the market that includes, in one single and easy to use package, all the scientific tools and functions necessary to discover tampering on an image or determine originality, and to verify if a picture has been generated by a specific device. 

This update includes some very big improvements and additions.

Fourier

Amped FIVE users will be aware of how powerful the Fourier domain is in identifying and then removing frequency noise in images. This frequency noise can also be used to identify signs of LCD Recapture. As a result, this filter is now included in Authenticate.

Amped FIVE Update 8678: Faster Redaction and Automatic Pattern Removal

Well, here we are again, with another exciting update to Amped FIVE.

Before we dive in and take a closer look at all the developments, I want to say a quick thank-you to the users of Amped FIVE who have suggested refinements and requested new functionality to help them and others in their Forensic Image and Video work. We develop this software for you. If you need it, we will deliver it!

OK, let’s get to it!

Dynamic Tracking

It is one of those tasks that, in small amounts, can be quite enjoyable. However, when you are constantly spotlighting or hiding people, it quickly becomes tiring. That’s when mistakes are made, and it’s easy to miss something that could be detrimental in an investigation. Dynamic Tracking has been in the Selection box for some time but it has received a very powerful ‘upgrade’.
