Licensing And Activation

How the Face SDK licence is activated online or offline, how it is tied to your machine, what the Demo allows and what happens when a licence ends.

A licence key from ARSA activates one server. The licence states the edition, the modules (recognition, passive and active liveness, cameras, face attributes) and the limits, and the server enforces them.

Activate Online

Start the container with ARSA_LICENCE_KEY=<key>, or enter the key later in the dashboard under Settings, About, Licence. The server sends the key, the product name, salted hashes of machine identifiers and its public keys to ARSA’s licence server and receives the signed licence. No face data, names or photos are sent.

Activate Offline (Prod)

For servers without internet access:

  1. In Settings, About, Licence, choose Make an offline request and save the request file.
  2. Send the file to ARSA.
  3. Import the licence file you receive with Import the licence file, and set NF_LICENCE_SERVER=off.

The Demo cannot be activated offline.

One Licence, One Machine

The licence is bound to one machine. Run the install command on the machine you want to use; it needs sudo, and rootless Docker is not supported.

Check-Ins

Prod checks in as its licence requires; the Demo checks in once a day. A missed Demo check-in stops analysis until the next one succeeds.

The Demo

  • 14 days from the first activation, 100 people, 50 API calls an hour.
  • It can move to another machine twice, one machine at a time; a third move needs ARSA.
  • At the end of the 14 days analysis stops at once: the API refuses face calls and the dashboard shows that the Demo has ended, with a link to buy a licence. Your data is kept.
