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.

Video recording is a frequent practice nowadays but when it comes to law enforcement agencies, especially Police, recording videos through body-worn cameras, dashcams, CCTV, mobile phones has raised privacy protection concerns.  

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

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

Unlike document or image redaction, a massive amount of video data has been collected. Redaction is done to conceal sensitive information within multiple video frames, which is a challenging task. 

In this article, we will discuss how you can redact a video in different ways. 

Traditional Methods of Redaction: 

Manual redaction of an image: 

In the past, as there was less digital data available, documents and images were redacted manually. 

This means concealing sensitive personal data manually with a black redaction box. It involves choosing an image to redact, searching for the objects you want to redact in an image, setting redaction configurations e.g., size, shape color, and opacity of redaction box. Drag to draw a redaction box on the objects u have selected then redact it. 

Too much effort, honestly! 

How is Manual Redaction Done on 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 it. 
  • 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.  

As video redaction must be accurate, complete, and legalized, there must be well-defined tools for video redaction rather than redacting them manually.  

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? 

Automatic Redaction: Current Approaches to Video Redaction 

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, saving time and money. 

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