Introduction

We’ve put together a handful of sample images and their responses to kickstart your API testing efforts. You are free to download them and use them in testing the API and webhook. Please remember that many applications destroy signed data on upload or resizing, so be sure to upload these directly to a compatible destination, like s3. If you need to send images to others, send via a zip file.

Ordinary Image

This is a standard JPEG that does not have any signed data in it. It is not a Truepic.

Response Highlights

No verification present.

  ...
  "verification": {
    "status": "ERROR",
    "error": {
      "message": "Error: No manifest present in jpeg"
    }
  },
  ...

Valid Truepic

This is an example of a signed JPEG taken with the Lens SDK in a mobile application. Most of your captures should look this way.

Response Highlights

If each section under verification has a status of validated its a Truepic!

 "verification": {
    "status": "SUCCESS",
    "assertions": {
      "hash": {
        "status": "validated"
      },
      "location": {
        "status": "validated",
       ...
      },
      "device": {
        "status": "validated",
       ...
      },
      "date_time": {
        "status": "validated",
        ...
      }
    },
    ...
    "signature": {
      "status": "validated",
      ...
    },
    "trusted_timestamp": {
      "status": "validated" || "OFFLINE",
      ...
    },
    ...
  },
  

Recapture Failure

This photo is a valid Truepic, however it failed recapture detection and is likely a picture of a screen.

Response Highlights

If status returns as WARNING a recapture is suspected.

  "recapture": {
    "status": "WARNING",
    "blur_score": 95,
    "entropy_score": 1.29,
    "recapture_score": 0.999
  },

Image Search Failure

This photo has been found elsewhere on the internet. This means that it is a recapture of a pre-existing image.

Response Highlights

If status returns as MATCH images were found and flagged.

 "reverse_image_search": {
    "status": "MATCH",
    "url": "https://buscouncoche.es/wp-content/uploads/2018/04/como-saber-el-kilometraje-real-de-un-vehiculo.jpg"
  },

Invalid Credientials

Whether due to deliberate hacking or errors, sometimes a Truepic will be invalid.

Location Within Threshold

This example shows a positive result with our location comparison feature.

Response Highlights

location.comparison.distance_threshold_exceeded is false!!

Location Exceeds Threshold

This example shows a negative result with our location comparison feature, meaning that location in the photo’s metadata is not within the allowed threshold of the address provided that it is being compared to.

Response Highlights

location.comparison.distance_threshold_exceeded is true. True distance is provided.
