Licensing Principles

The FindFace Multi licensing is granted using the following criteria:

  1. The overall number of extracted feature vectors, regardless of the object type (face, body, car).

    Note

    The feature vectors are extracted from objects detected in the video, from dossier photos and user photos, and when building so-called person centroids.

    The licensing scheme is the following:

    • Events: 1 event of video object detection = 1 object in a license.

    • Dossier: 1 photo in a dossier = 1 object in a license.

    • Persons: 1 person = 1 object in a license.

    • Users: 1 photo of a user = 1 object in a license.

  2. The number of video sources currently in use (i.e., active video processing jobs for cameras and video files).

  3. The number of model instances in use in the findface-extraction-api component.

  4. Face attribute recognition: gender/age/emotions/glasses/beard/face mask.

  5. Body attribute recognition: clothing color/type.

  6. Car attribute recognition: make/model/color/body style.

  7. License plate recognition.

  8. Face liveness detection.

  9. Integration with partners.

You can choose between the following licensing methods:

  • The online licensing is provided by interaction with the NtechLab Global License Manager license.ntechlab.com and requires a stable internet connection, DNS, and open port 443 TCP. Upon being disconnected from the internet, the system will continue working off-grid for 4 hours.

Note

It is possible to prolongate the off-grid period for up to 2 days. Inform your manager if you need that.

  • The offline licensing via a USB dongle requires a USB port on the physical server with the findface-ntls component (license server in the FindFace core).

  • The offline licensing via hardware fingerprint requires Sentinel drivers installed on the physical server with the findface-ntls component.

Important

For the system to function, a single instance of findface-ntls should be enough. If your system requires more license servers, contact your NtechLab manager beforehand to prevent your system from being blocked.

View and Update License

After installing FindFace Multi, upload the license file you obtained from the manager into the system. To do so, navigate to Preferences -> License.

license_en

Use the same tab to consult current licensing information and upgrade your license.

Offline Licensing via Hardware Fingerprint

To implement the fingerprint licensing to your system, do the following:

  1. Inform your manager that you are going to apply this licensing method and request your unique license id.

  2. On the physical server with the findface-ntls component, install the Sentinel drivers.

  3. In the FindFace Multi web interface, navigate to Preferences -> License. Take a hardware fingerprint (C2V file) by clicking the Download C2V for activation button.

    Tip

    If you prefer working with the console, you can send the following API request to findface-ntls instead:

    curl 'http://<findface-ntls-server-ip>/ntls/c2v' >my_pc.c2v

  4. Send the license id and the C2V file to your manager and receive your license file in return.

  5. On the License tab, upload the license file.
