How to Redact a Video Efficiently?

This article will discuss how to redact a video, the drawbacks of manual redaction and current approaches of automatic redaction.

In today’s data-driven world, ensuring the privacy and security of sensitive information has become more critical than ever.

In the field of criminal justice, digital evidence captured from various digital devices such as Body-Worn Cameras, Dashcams, and CCTVs has become an essential aspect of modern investigations.

But this has raised privacy protection concerns!

To address these concerns, video redaction can be done to obscure any personally identifiable information of individuals such as victims, criminals, innocent bystanders, undercover police officers, etc., visible in videos.

Legal departments must ensure that the personal information of individuals involved in a case, such as social security numbers, addresses, phone numbers, and other sensitive information, is redacted to protect the privacy and security of individuals.

A few years back, redaction was simply obscuring a portion of printed text documents or hiding personal information manually from documents or images with a black box.  

Unlike document or image redaction, concealing personally identifiable information within multiple video frames is a challenging task.

For this reason, you need effective redaction procedures in place that make your job easier for you.

Let’s explore how to redact a video in different ways.

Traditional Methods of Redaction

The traditional approach involves the manual redaction of images and videos using simple editing software to obscure sensitive and confidential information that should not be revealed.
Let’s take an example of image redaction!

Manual Redaction of Images

The process of image redaction entails manually hiding sensitive personal data using a black redaction box. The procedure involves several steps: first, select the image that requires redaction, then identify the specific elements within the image that need to be hidden.

Next, adjust the redaction parameters, such as the size, shape, color, and transparency of the redaction box. Afterward, you draw the redaction box over the selected elements manually and finally apply the redaction to effectively conceal the chosen content.

Too much effort, honestly!

One of the benefits of manual redaction is that it is highly customizable, allowing users to redact information in a way that is most suitable for their specific needs. However, manual redaction is time-consuming and can be prone to errors, as it relies on the user's attention to detail.

Along with time consumption, manual redaction may not be completely secure for highly sensitive information, as certain techniques could potentially reveal the redacted content.

For more secure redaction, especially when dealing with sensitive documents, it's best to use specialized software or tools designed specifically for redacting digital content.

Manual Redaction of Videos

To redact a video, you would need to:

  • Firstly, record a video.

  • Then upload it to a database. 

  • Identify objects to be redacted entirely or a portion of them. 

  • Redact through blanking out or blurring options or drawing boxes or shapes over people and objects by hand. 

  • Scan the videos frame by frame and draw boxes over the targeted objects. 

Manual redaction of videos in this way is not efficient or accurate in certain circumstances as it has some drawbacks. 

  • Mostly, each copy of the video utilizes extra storage resources.  

  • At times when u need to remove a major part of the video, like revealing only one person, u cannot do it manually on time. 

  • Chances of human error and inaccuracy. 

  • Time-consuming and expensive. 

  • If a person is running, it is difficult to redact his different face angles within all video frames manually.  

With the increasing digitization of data and the prevalence of videos, more sophisticated redaction techniques are required to effectively protect privacy in modern times.

For legal purposes, Law enforcement agencies need an efficient redaction tool that can redact confidential information in evidence videos quickly and with accuracy so that they can focus more on investigation rather than wasting time on laborious things. 

So, what is the solution? 

Use the power of AI for redaction!

AI-Powered Redaction: Current Approaches to Video Redaction

Automatic redaction is a method of using AI to detect and redact sensitive information in the video automatically. It is a convenient and time-efficient method that can save significant effort and resources. It uses advanced algorithms to identify and redact critical information, such as faces, license plates, and other details, automatically.

The automatic redaction has two paramount features.

  • Object Detection feature
  • Object Tracking feature

These features have upgraded the entire process of manual redaction. The redaction system automatically follows objects frame by frame using artificial intelligence, reducing human effort, and saving time and money. 

To give an idea, we will take our tool as an example and explain how we do it.
