Quantitative Results

This article describes how to get the analysis scores.

When you perform an analysis, the result you get is a number. For biometry, it reflects a chance that the two or more people represented in your media are the same person. For liveness, it shows a chance of deepfake or a spoofing attack: that the person in uploaded media is not a real one. You can get these numbers via API from a JSON response.

1. Authorize.

2. Make a request to the folder or folder list to get a JSON response. Set the with_analyses parameter to true.

3. For the Biometry analysis, check the response for the min_confidence value:

"items": 
 [
  {
   "analyses": 
    [
     {
      "analysis_id": "biometry_analysis_id"
      "folder_id": "some_folder_id", 
      "type": "BIOMETRY", 
      "state": "FINISHED", 
      "results_data": 
       {
        "max_confidence": 0.997926354, 
        "min_confidence": 0.997926354
       }

This value is a quantitative result of matching the people on the media uploaded.

4. For the Liveness Analysis, seek the confidence_spoofing value related to the video you need:

"items": 
 [
  {
   "analyses": 
    [
     {
      "source_media": 
       [
        {
        "media_id": "your_media_id", 
        "media_type": "VIDEO_FOLDER",
        }
       ]
      "results_media": 
       [
        "analysis_id": "liveness_analysis_id",
        "results_data": 
         {
          "confidence_spoofing": 0.55790174
         }

This value is a chance that a person is not a real one.

To process a bunch of analysis results, you can parse the appropriate JSON response.
