Forensic Video Enhancement Techniques

The objective of Forensic Video Enhancement is to clarify or enhance the events as they occurred. This is done using non destructive techniques to preserve the video evidence integrity, and pixel quality.

As DLA, the digital forensics experts are often asked to enhance CCTV Surveillance video recordings for court. Often times they are asked to provide video image enhancement as well for identification purposes.

A variety of video enhancement techniques can be applied in different arrangements on CCTV Surveillance video evidence. The most important ingredient to this forensic process is maintaining the highest quality of the video evidence. This yields the highest success possible throughout the investigation.

DLA will now be an Africa exclusive agent for Ikena Forensic Software. Not only does Ikena offer some of the best software programs available today, but full enhancement of your videos and images will always be possible!

Scaling/Pixel Interpolation: Re-size, or scale an image or video to a larger resolution to further identify suspects.

Sharpening: Enhances the edge contrast of an image or video.

Stabilization: This is most common today with smart phone video evidence. It reduces the amount of movement from the user that created the video evidence.

Frame Averaging: Increase the quality of the image by combining data from surrounding frames as well as a better signal to noise ratio in your images or videos.

Speed Reduction: Decrease the original playback of video evidence to view the events as they occurred in more detail. 

If you have a video that you question or need help understanding, please give DLA a call!

Video Enhancement: What is and is not possible

Digital forensic and video enhancement specialists are asked on a regular basis to enhance images that have been recorded.

One of the goals of video enhancement, in some cases, is to be able to see persons faces better than they are when viewing the video under normal circumstances. Other times they are asked to enlarge and clarify a video in order to identify, for instance, the license plate on a car that is alleged to be involved in criminal activity.

With video enhancement, forensic experts can only do so much. In a lot of cases, the video that has been exported from the surveillance system is small and when enlarged, or zoomed in on the objects of interest they become very blurry and distorted.

BUT, we are proud to announce that our forensic experts at DLA will now be an Africa exclusive agent for Ikena Forensic Software! Not only does Ikena offer some of the best software programs available today, they also insist that full enhancement of your videos and images will always be possible!

Now you no longer have to stress about not having the highest possible quality surveillance system and video – Take a look below to see Ikena video enhancement in action...

Digital Evidence – How It’s Done

Computer documents, emails, text and instant messages, transactions, images and Internet histories are examples of information that can be gathered from electronic devices and used very effectively as evidence. 

For example, mobile devices use online-based based backup systems, also known as the “cloud”, that provide forensic investigators with access to text / messaging app messages and pictures taken from a particular phone. These systems keep an average of 1,000–1,500 or more of the last text messages sent to and received from that phone.

In addition, many mobile devices store information about the locations where the device travelled and when it was there. To gain this knowledge, investigators can access an average of the last 200 cell locations accessed by a mobile device. Satellite navigation systems and satellite radios in cars can provide similar information. Even photos posted to social media such as Facebook or Instagram may contain location information. 

Photos taken with a Global Positioning System (GPS)-enabled device contain file data that shows when and exactly where a photo was taken. 

Investigators can collect a great deal of history related to a device and the person using it!

Your deleted WhatsApp messages might not be as 'deleted' as you thought

Sometimes, the delete option is your best friend.

WhatsApp brought you the two-tick (so you can’t hide the fact that you’ve received a message) and then the blue ticks (so you can’t hide the fact that you’ve read a message).

In April - despite much controversy following the San Bernadino attack, in which the FBI had paid almost £1 million to unlock the iPhone used by one of the shooters - WhatsApp went ahead with end-to-end encryption.

This means that while you can’t hide your ghosting antics from the person in question, you can hide your messages from third parties.

But according to a new blog post, an iOS device might actually still store your "deleted" messages.

The data works similarly to your laptop’s hard drive: you might be able to delete the WhatsApp messages, but deleting it doesn't overwrite the data, which means it can still be retrieved.

When you backup your iPhone with iCloud the data gets copied to a less secure forum.

While the information can’t necessarily be accessed by a third party, it is still stored locally on your device which means that the only real way to get rid of it is by deleting the app.

Even then, the police can still potentially access it.

Law enforcement can potentially issue a warrant with Apple to obtain your deleted WhatsApp chat logs, which may include deleted messages.

Basically, the delete option may not be that great friend after all.

What Exactly is Computer Forensics?

The field of computer forensics has grown to become a science in itself. Computer forensics is also known as cyber forensics. It involves applying computer investigation and analysis techniques to solve a crime and provide evidence to support a case. Investigators often use proprietary forensic applications and software programs to examine computer hard drives, extract certain types of data from files and folders, and also to recover information from encrypted files. This digital information must be organized and documented into an official report form to be presented in a court of law.

Computer Forensics Defined

The computer forensics definition can be broken down into several technical aspects of the actual science of computer forensics. The general definition of computer forensics is the processes and investigative methods used to find digital evidence and prepare it for legal proceedings. The more in-depth definition includes the preservation of media and data, identification of computer-related evidence, extraction of the data and interpretation. Interpretation is perhaps the most important element of the computer forensics definition because this is where forensics experts must draw conclusions from a formal forensic analysis.

Throughout the process of data gathering and interpretation, the computer forensics specialist must document everything in a structured fashion. They must report exactly what types of investigations were performed and document all of the steps taken to retrieve various files, folders and data. The courts can then apply various types of methodology and testimonies in order to determine whether evidence presented can actually be used in the legal proceedings. This is why computer forensics specialists must learn about the different legal processes involved in an investigation and make sure that there is always a high level of integrity of evidence.

Why the Computer Forensics Definition Can Change

It's important to recognize that there are two main types of computer forensics investigations so the computer forensics definition can change. The first involves investigations where a computer or digital technologies were used to perform the crime (cybercrime). The second is when a computer is used as the target of a crime, such as when a hacker retrieves sensitive information or someone has their identity stolen online. In both of these situations, the computer forensics definition may change slightly because the investigator uses different techniques and methodologies to solve the crime.

The digital forensic experts from DLA use their knowledge of investigation and forensic software to find and reveal the computer or mobile forensic evidence that your require.
