Introduction  

The VIDIZMO Audio Indexer App enables you to detect and redact Personally Identifiable Information (PII) from your transcribed audio and video files. You can configure the application to perform this functionality automatically on files uploaded to your Portal, or you can process your content manually with on-demand processing. In addition to this, you can open your transcribed audio or video in VIDIZMO's Studio Space to view the identified PIIs and selectively redact them with additional information, such as their confidence score or classes. 

 

Note: Transcriptions are required for PII detection. If no transcriptions are found for an audio or video, the VIDIZMO Audio Indexer app will automatically generate them if it is configured to detect any PII type. 


Pre-requisites  


PII Redaction via Automatic Processing 

Configure the VIDIZMO Audio Indexer for automatic processing with your preferred PII entities selected to enable automatic detection or redaction of PII on Portal. After the application is enabled after the configurations, audios and videos uploaded to your Portal will be processed for this automatically. 

 

Refer to Configuring VIDIZMO Audio Indexer for PII Detection and Redaction for a guide on configurations. 

 

Automatic processing occurs in the following scenarios:  

  • When content is uploaded.  
  • When content is ingested.  
  • When a VIDIZMO Live session is saved and published. Refer to Understanding Live Streaming in VIDIZMO for more information regarding live streaming in VIDIZMO.  

  

Let us demonstrate how you can upload content for automatic PII Redaction.  

  1. Click the "Add Media" button to navigate to the Add New Media page.  
  2. Select "Upload Media" to upload an audio or video file.  


3. Edit the Media Settings of your uploaded file, and then click "Save and Close" or "Save" to add it to your Portal for processing. 



4. Once the file is processed, open it and click the "Transcription" icon to see the generated Redacted PII entities in the transcription pane.

Note: On the playback page, you will also find the Media Culture attribute of the content. 
 

5. You will also find that the content has been tagged with a "Redacted" tag on the thumbnail, indicating that it has gone through a redaction activity. 



PII Redaction via On-Demand Processing  

On-Demand Processing During Upload 

  1. When Custom Upload is enabled, EVCM users get access to the "Process Tab" in their Media Settings where they can select options to process the files during upload. DEMS users get "Custom Settings Upload" instead of the default "Upload Evidence" as an option to upload files.  
  2. After uploading a file, select "Generate AI Insights" on the Process tab.    
  3. Next, add the PII entities that you want to redact in the Insights field. The options available here depend on what PII entities you’ve selected in the Audio Indexer's application settings.  
  4. Save your settings and initiate the processing by clicking “Save And Process.” 



On-Demand Processing from Process Modal 

  1. To perform on-demand processing via the Process modal, select "Process" from the overflow menu of the audio or video. 
  2. You can also perform on-demand processing on multiple files by selecting the content and then clicking “Process” from the header menu. 


3. On the Process Modal, select "Generate AI Insights" to display the processing options.    
4. Add the PIIs that you want to redact in the Insights field.  
5. Click "Start" to begin the processing. 



PII Detection and Redaction via Studio Space 

Studio Space offers functionalities that enable you to customize your PII detection and redaction activities. It lets you view the terms classified as PII, along with their corresponding type and confidence score. You can also select and redact these detections independently, giving you more control over the information you want to redact.  

  1. Click the overflow menu of the media or evidence and select studio space. 



2. Once it is opened in Studio Space, select the Auto Detect button to see the AI Insights you can generate. 


 

3. Add the PII entities you want to detect in the detection classes section.

4. Click ‘Start’ to begin the detection process. 



5. The detected PII entities will be displayed on the pane on the left side along with additional information such as their confidence score and timestamps. You can also click these detections to navigate to the instance or time of when this object was detected or when this PII was spoken. 
6. You can also use the filter icon to filter these PII detections out via their class or confidence score. 



7. Select the detected PII entities that you want to redact and then select the redact icon. You can get a preview of the redaction results on the transcriptions on the right pane. 
8. To finalize and begin the redaction process, press the Redact button. 



9. After the processing is finished, the PII you've selected will be redacted as seen in the transcription. They won’t be available as detections on the left pane as well.
