With the prevalence of video recordings from smart phones, dash cams, body cams, and conventional surveillance cameras, privacy protection has become a major concern, especially considering legislation such as the Freedom of Information Act.
It is a frequent practice for organizations to redact sensitive information before releasing content outside. The content could be a paper document, audio file, or video.
Redaction is important because it can shield an individual’s personal data, like social security numbers, names of minor children, and financial account numbers, by removing them from public legal documents to ensure privacy.
Redaction in VIDIZMO is the act of obscuring faces, persons, objects, audio, or any other sensitive information from uploaded files. VIDIZMO provides the ability to redact personally identifiable information (PII) in video evidence files before sharing it with others. This can be done on our studio space which provides you out of creating redacted versions of video evidence files without affecting the original file.
With VIDIZMO redaction, users only need to click on the studio space from the video options to start the process. The AI tool will process the video and will point out the persons, faces and license plates. For a more accurate and enhanced process of redaction, users can outline the custom objects as they are seen in a video using the drawing tool. Make sure that the portal administrator has enabled the redaction activity from the admin panel, otherwise, other users will not be able to run the studio space.
In simple words, redaction workflow has three stages:
Detection -> Tracking -> Redaction
Understanding How The Feature Works
Users will select the duration of the video for which they want to run the redaction analysis. When the redaction process is initiated, the AI indexer will index the occurrence of faces, persons, objects, and license plates. Users can also draw manually to have undetected objects in the list. A rectangular box will appear around the entities that needs to be redacted.
For audio redaction, user can see the complete wave of the audio to select the duration for which redaction is required. That selected segment will be muted after redaction.
For redacting faces and objects, users can select how they want to redact it. The available options are blur, pixelate, and solid.
Timed Data Manipulations
The operations that can be performed on timed data such as faces/persons or audio segments include:
Multiple detections of the same instance can be merged. This feature is helpful if the automatic detection has labeled different occurrences of same instance as different objects.
An occurrence that has been selected automatically which does not need to be redacted can be deleted.
The AI tool detects and names the detected instances as person 1, object 1 etc. These names can be edited to identify exactly what detected instances are being redacted.
Studio Space Capabilities
Automatic Face Redaction
The AI video indexer begins to search and detect faces whenever a new redaction scanning activity is initiated by the user.
When the process is complete, a thumbnail image of each detected face is then displayed, these thumbnails can be used to select the individuals that should be redacted from the scene.
The processing time for auto face detection may vary depending on the video file size and will be affected by the resolution, length, frame rate, and other factors related to video. The success of the auto face detection can vary depending on the quality of the video and whether the subject is facing to the front or the side.
Automatic Person Redaction
Like face detection, while the video is being processed by the indexer for detection, it will detect persons appearing in the video frames and will show a thumbnail in the persons tab. Merge, edit, and delete actions are available for detected persons to enhance the redaction activity.
License Plate Redaction
The automatic detection tool can detect license plates in the video frames. License plates are also a part of PII so this sensitive information can be automatically detected and redacted from a digital evidence file.
Manual Object Redaction
To make the process more efficient, users can mark custom objects in the video using the drawing tool to have them redacted. For example, there is an appearance of a knife in the video and you want to hide it from viewing, you can simply outline the knife by using the drawing tool. Your outlined object will appear in the objects tab of the redaction studio and you will be able to blur, pixelate or put a solid box on the selected object.
Audio Segment Redaction
Users can select the audio segment they want to redact. It is not automatic, but it is quite easy as users only need to select the segment of the video where they think some sensitive words are spoken. The selected segment will be muted after redaction.
Redaction Studio Layout and Controls
Following is the screenshot of the studio space. These are the tabs where detected instances are shown to the user. Here, merge, edit, delete, and view options are available as discussed earlier in this article.
So far, the feature is discussed and a good understanding has been developed. Now, let us understand where this whole redaction process will be helpful. What can be achieved using these redaction tools in your video, how can you group them together for protecting sensitive information.
Redaction for Law Enforcement
Handling digital evidence is so important for better law enforcement. Hence, Law enforcement officers needs to redact and enhance all types of video footage, audio files, images, and PDFs from any source, including body cameras, in-car cameras, cellphones, and more. Designed to handle all proprietary formats and media, VIDIZMO makes it easy to redact sensitive documents and recordings, no matter what the format of the file is.
Redaction for Education
Education providers needs to comply with the Family Educational Rights and Privacy Act (FERPA). Protect personally identifiable information (PII) by removing identifying data. Education providers can easily redact students faces, people (i.e., entire bodies) and identifying characteristics like badges in streamed classroom sessions or any video footage.
Redaction for Health Care
Redaction for Government
Governing is hard enough; redaction does not have to be. Our strong security means your data stays safe, and a comprehensive audit log is secured throughout the editing process meaning agencies can focus on mission-critical tasks instead of managing unnecessarily complicated redaction workflows. Compliance officers, FOIA specialists, and records specialists can automatically redact complex video footage with thousands of faces, license plates, papers, vehicles, bodies, and screens.
