Griaule Biometrics

Some of Griauleā€™s software requires the use of a product key in order to activate the licensed copy.

A product key is a unique combination of numbers and letters that is used during Griaule software registration to "unlock" the product. If you do not activate it using the product key, the product will always show a splash screen until you register the copy with the product key.

NOTE: A product key is not a license file or product ID (PID) number. A license file is created after a product is successfully installed and registered using the product key.

When the customer purchases a license package, he receives a "product key", and the number of licenses he bought is credited in his account. With this product key, the user can have access to all the licenses in his account.

The combination of the product key with the licensing methods has brought a robust way of licensing.

Licensing Methods

The registration process is only finished after Griauleā€™s server is contacted and from it a license file is downloaded. There are few ways to do that.

1. Using the SDK API to register the software

This is by far the easiest way. You just need to call the installLicense method at the beginning of the application.

Suppose your product key is AAAAA-AAAAA-BBBBB-KKKKK , then before initializing the sdk, the calling line would be like showed below.

griauleEngine.installLicense("AAAAA-AAAAA-BBBBB-KKKKK")

NOTE: You donā€™t need to verify if a license is already installed in the machine. The method does that for you.

NOTE: Before calling the installLicense() method, if you want to change the default directory the license is installed, you must call the method SetLicenseFolder() first.

Following is a picture with the overall idea.

Note that this code needs to be executed at least once (if it executes more than one time, no problem). The first time this code is executed, it connects to Griaule's server, checks if the user still has license credits available, if yes, it decreases the number of available license credits by one, and finally generates, downloads and installs a license file on the computer it is being executed.

2. Using Griaule's License Manager

The License Manager is an application useful if you want to install the software on a large amount of computer that have no internet access.

If you want to manage your licenses, or if the machines that you want to install the licenses don't have internet access , you can use griaule's license manager. You just need to collect the hardware keys of your machines with the license manager, then you go to your account in griaule's website, download the license , and install in your machines.

3. Using the Griauleā€™s icon tray

This is a straightforward way of register the software. Once you have the Griauleā€™s software running on the computer, a icon will show up on the icon tray. Right-clicking Griauleā€™s icon will open a pop-up menu, choose the option ā€œOnline Activationā€ and enter the Product Key. A message confirming the activation will be shown.
