Privacy concerns have been predominant and prevalent when it comes to handling enormous amounts of data. One such scenario where this phenomenon occurs is when we work with computer vision technologies such as face detection.
Our blog will be discussing matters revolving around privacy concerns with face detection and recognition technology. Later on, we will present a possible solution for the issue at hand – face redaction and how to use VIDIZMO and AI to redact faces.
Face detection is an incredible development in the field of artificial intelligence and computer vision. However, it has been considered questionable in many regards. Facial recognition, which allows identification of the faces being detected, also adds to the list of concerns amongst people.

Facial detection, and if further enhanced, facial recognition is growing into a staple technology of the near future for many departments. The potential it carries, however, is not convincing enough for those who are concerned with its risks. For example, as per a survey by Reservations.com, over 32.5% of US citizens do not approve of the use of this technology at airports for better security and faster boarding, due to the privacy concerns that it brings with it.
The breach of privacy of individuals, the presence of individuals such as minors and those not concerned with a matter at hand, such as bystanders in a crime scene, as well as the exposure of PII (Personally Identifiable Information) information, all are matters which have led several US states, cities, and law enforcement jurisdictions to rethink the implementation of facial recognition technology.
This becomes a greater issue when video footage is being presented on a public medium, played as evidence in court, or accessed and viewed in some other manner, rather than when at rest in storage.
One of the solutions to counteract the issues we discussed is the implementation of redaction. Face redaction would allow us to obfuscate the faces of individuals present in the video footage at hand. To do this, however, initially, a face detection computer vision algorithm would have to be executed to detect all the faces present in the video, which would later be redacted.
With the implementation of automatic face redaction, all faces present in the video will be redacted automatically. This helps us meet the general compliance requirements set by law enforcement and regularity firms, which redaction serves to fulfill.
The CJIS, CRoC, HIPAA, FEDRamp, CCPA, GDPR and the California State Bill 748 (SB-748) are amongst those that emphasize redaction for all video evidence and media.
Face redaction initially works with the placement of a layer over the video stream, where the masking is done. Using this layer, selections are made where faces appear onscreen. These selections, or bounding boxes, are then filled with an opaque color, blurred out or pixelated, to obfuscate the face within. This is how manual face redaction works.
If the process is automated, an AI algorithm allows for facial detection, which can later be redacted with ease with a few clicks. Facial recognition, as mentioned earlier, adds further to the process by making it more efficient in cherry-picking whom to redact and who to not redact.
Countless tools are available for use in the market for redaction. However, only a few of the best redaction tools provide automatic redaction for video, audio and imagery. Each of these has varying parameters that make them compete against one another.
VIDIZMO’s Redaction Tool is amongst these names of one of the leading redaction tools in the market, in terms of services offered. That is because VIDIZMO’s redaction tool provides automatic video and audio redaction through on-demand face detection, making it easier for you to redact videos when ingesting several terabytes of data from multiple sources.
Apart from that, the tool also holds a multitude of features that make it one of the best the market has to offer.
