Providing a unique identity for a resident is one of the key features of any identity platform. To achieve this, MOSIP interfaces with an Automated Biometric Identification System (ABIS) to perform the de-duplication of a resident's biometric data.
The ABIS system never learns about residents' identities. Any Personally Identifiable Information (PII), such as demographic details or an applicant's AID (application ID), is not shared with the ABIS system. Internally, MOSIP maintains a mapping between the ABIS-specific reference ID and the AID of the resident.
ABIS is used for 1:N deduplication. For 1:1 authentication, Biometric SDK is used. MOSIP does not recommend using an ABIS for 1:1 authentication.
MOSIP interacts with ABIS only via message queues. The JSON format is used for all control messages in the queue. MOSIP ABIS middleware sends requests to the inbound queue address and receives responses from the outbound queue address. ABIS must comply with the interface defined in ABIS API Specifications
