"Handling policies" section#

The section is available only to a user with the administrator role.

The “Handling policies” section is intended for creating, deleting, viewing policies, and editing their parameters (Figure 32).

Handling policies (handlers) can be static or dynamic.

If the handler is static, its parameters are specified when creating the handler.

If the handler is dynamic, then you can change its parameters when generating an event. For this, create a generate events request with a specific content type (see API Reference Manual of the LUNA PLATFORM 5 documentation). In a dynamic handler, administrator can allow users to specify parameters that change with each request. At the same time other technical parameters can be set separately and left hidden from the user. With a static handler, administrator would have to create a new handler for each new task.

“Handling policies” section contains the following elements:

table of policies:
“Description”—policy name;
“Handling policy ID”—policy identifier;
“Handler type”—static or dynamic policy;
—button for editing policy parameters (1);
—button for deleting the policy (2);
“Add static” button—button for creating a static handling policy;
“Add dynamic button—button for creating a dynamic handling policy;
the number of policies displayed on the page is set by the switch in the lower right corner of the page. There can be 10, 25, 50 or 100 policies in total on one page (3).

Policy creation#

Static policy creation#

To create a static policy, click on the “Add static” button (Figure 32). A form will open to select how to create the static policy (Figure 33):

preconfigured typical policy templates (policies 1–6);
step by step custom policy (“Other”).

Figure 33. Selecting the template of static policy

To quickly create simple static policies, use one of the typical policy templates.

Six standard templates are available:

“Policy 1. Registration of a reference descriptor (with saving to a list)”—allows user to detect a face on the frame, check Liveness, and save the face to a specified list;
“Policy 2. Biometric identification of faces (without saving to a list)”—allows user to detect all faces in the frame and compare them with all faces in the specified list;
“Policy 3. Saving the faces identified in the list to the database”—allows user to detect all faces on the frame, check Liveness, compare detected faces with all faces in the specified list, and if the comparison is successful, save the face to the specified list;
“Policy 4. Determination of attributes and properties of a face without identification (gender, age, emotions, etc.)”—allows user to detect all faces in the frame, perform all possible checks, and save the event;
“Policy 5. Saving events for unique faces for later counting”—allows user to detect all faces in the frame, check Liveness, compare the detected faces with all faces in the list of unique faces, and if this face is not in the list, save the face to this list of unique faces;
“Policy 6. Registration of a reference descriptor with verification of compliance of the photo with the requirements of biometric standards—allows you to save the reference descriptor in a specific list only for those photos that have been verified in accordance with the biometric standards.

The following checks are missing in the beta version:

it is not allowed to use retouching and image editing;
image cropping is allowed;
compression code: JPEG (0 x 00), PNG (0 x 03).

When user clicks on a line with a standart template (policies 1–6), a window opens for entering the main parameters of a preconfigured policy (Figure 34).

Figure 34. Form for entering basic parameters and creating a preconfigured static policy (policy 1)

Fill in all the required parameters and click on the “Create” button. A window will open with a message about the successful creation of the policy (Figure 35).

Figure 35. Message about the successful creation of the “Registration of a reference BT” static policy (policy 1)

Click anywhere outside the successful static policy generation message to navigate to the “Select the type of policy you want to create” form (Figure 33).

To create a unique static policy that requires detailed parameter settings, use the step-by-step custom policy.

When user clicks on the line with a step-by-step custom policy (“Other”), a form for step-by-step static policy creation will open (Figure 36).

Fill in all the required parameters and click on the “Next” button to proceed to the next step. After setting all the parameters, a window with a message about the successful creation of the policy will open.

Dynamic policy creation#

To create a dynamic policy, click on the “Add dynamic” button on the page with the list of policies (Figure 32). In the opened window, enter the name of the new dynamic policy and click “Save” (Figure 37). If you need to go back to the page with the list of handlers during creating a handler, press the Esc key on your keyboard.
