Identity Scanner

Identity Scanner is a Zia AI-driven component that enables you to perform secure identity checks on individuals and documents by scanning and processing various ID proofs or official documents. It is a comprehensive suite that incorporates multiple functionalities divided into two major categories- E-KYC and Document Processing.

Note: Catalyst does not store any of the files you upload in its systems. The documents you upload are used for one-time processing only. They are not used for ML model training purposes either. Catalyst components are fully compliant with all applicable data protection and privacy laws.

Facial Comparison

Facial Comparison, also known as E-KYC, is a part of Identity Scanner that compares two faces in two different images to determine if they are the same individual.

Note: While the Document Processing feature of Identity Scanner is only relevant to Indian users, the Facial Comparison API and SDK tools are available to a global audience. However, accessing and testing Facial Comparison or E-KYC from the Catalyst console is restricted to the users from IN DC alone.

Process Facial Comparison

Description

This API enables you to perform a face comparison between a source image and a query image. You must specify the paths to both the image files in the API request, as shown in the sample request.

Note: You can mark either the ID proof image or the individual’s photograph as the source or the query image. This will not affect the results.
