Voice Biometrics Profiles

Overview

Voice Biometrics (VB) use profiles that can be easily set up in OCP Console®.

A profile is a set of configurations for Voice Biometrics. A client/group can create and manage multiple profiles if they need to have different VB configurations for different lines of business.

Create a VB Profile

1. Select the Voice Biometrics → Profiles from the Console menu.

2. Click the Create button.

3. Add the information in the Create new Profile window.

4. Click the Create button and the new VB profile will be added to the list of profiles.

Manage Profiles

In the Manage Profiles section, click the Menu icon of a profile to select the following actions from the list:

• Disable/Enable

• Duplicate

• Delete

Edit the VB Profile

Click on a profile name from the profiles list to edit it. The parameters you can edit to a profile are:

• Add biokeys

• Rename/delete biokeys

• Mark a bioKey as bioUser ID

• Rearrange bioKeys priority

• Select a Match Policy

Edit the Biokeys

Biokeys are used to identify a caller. You can set as many biokeys to be used for caller VB recognition but only one can be marked as bioUser ID. The bioUser ID is the ID that uniquely identifies a VB user. The biokey that is marked as user ID is mandatory when enrolling a caller, whereas the rest are not.

In the Biokeys tab, the default biokeys are created. These are user_id and Ani.

Add a Biokey

To add a biokey, follow the steps:

1. Click the Add Biokey button to open the Create new Biokey window.

2. Type a biokey name in the corresponding field.

3. Check the sensitive data box if the selected biokey contains sensitive data.

4. Click the Create button and the new biokey will be added to the list of biokeys for the selected profile.

Rename / Delete Biokey

Click the Options menu icon of a biokey to rename it or delete it.

Match Policy

In case we have multiple biokeys, we set a priority number on each biokey, and use those priorities to sort or limit the search results from the enrolled users.

Select a matching policy from the dropdown menu.

• MATCH_ALL: Search results contain bio-users that are matching all the biokeys that were used for searching. For example, if we search with an ANI and a zipCode, the results will match cases that contain both values.

• MATCH_ANY: Search results contain bio-users that are matching any of the biokeys that were used for searching. For example, if we search with an ANI and a zipCode, the results will match any one of the two values. Then priorities on biokeys are used to sort the results.

• MATCH_TOP_PRIORITY Search results contain bio-users that are definitely matching the top priority biokey, and optionally the rest of the biokeys that were used for searching. For example, if we search with an ANI with priority 1 and a zipCode with priority 2, the results will match the ANI value and optionally the zipCode value.

Change Biokey priority

Drag and drop biokeys in the list to change their priority.

Calibrate verification thresholds

Select the Thresholds tab to manage thresholds. Threshold levels are used for acceptance criteria as well as for measurement of performance metrics.

1. Click on any threshold number on the threshold bar and drag it along the bar to change it.

2. Click the Save changes button to save the setup or the Reset changes button to move back to the previous setup.

Models

In the Models tab, you can find the information regarding the biomodel and basemodel used in the corresponding profile.
