Introduction

An ABIS system that integrates with MOSIP should support the following operations.

All ABIS operations are via. a message queue and are asynchronous. The data sent in ABIS can be byte array or text based on a configuration in the registration processor.

Parameters

ABIS Operations

The following operations are supported by MOSIP:

Insert

  • ABIS must get biometric data from referenceURL, process it and store it locally within the ABIS reference database. More details about the referenceURL is mentioned in our referenceURL section.

  • referenceId must not be active prior to this operation i.e., it must not have been used before this operation.

  • De-duplication must not be performed in this operation.

  • MOSIP will provide biometric data in CBEFF format to ABIS as a response of referenceURL and the data will be encrypted and encoded as mentioned below.

Request and Response Structure for Insert

Insert Request

  "id": "mosip.abis.insert",
  "version": "1.1",
  "requestId": "91234567-89AB-CDEF-0123-456789ABCDEF",
  "requesttime": "2020-03-29T07:01:24.692Z",

  "referenceURL": "https://{base_url}/v1/datashare/get/mpolicy-default-abis/mpartner-default-abis/mpartner-default-abismpolicy-default-abis20210205062412BlQo0rJB"
}

  "responsetime": "2020-03-29T07:01:24.692Z",
  "returnValue": "2",
  "failureReason": "7"
}

Reference URL

The reference URL is MOSIP's datashare URL which is generated based on a policy defined by MOISP's adopter.

  • The referenceURL is authenticated and authorized; ABIS needs to send a JWT token inside the request header COOKIE.

  • The referenceURL will be active for a certain time as decided by the MOSIP adopter.

  • The data sent in the referenceURL will be encrypted.

Authentication Token

As mentioned above in order to access the request URL the ABIS system needs to send a JWT token inside the request header COOKIE. In order to get the token ABIS needs to call MOSIP's AuthN & AuthZ API with Client ID & Secret Key by passing the credentials (clientid, secretkey and appid) which would be provided by the System Integrator (SI).

Below are the sample API details for getting the authentication token. More details about the API are available in our AuthN & AuthZ document.

Sample Request URL

POST https://{base_url}/v1/authmanager/authenticate/clientidsecretkey

Sample Request Body

{
  "id": "string",
  "metadata": {},
  "request": {
    "appId": "regproc",

  },
  "requesttime": "2018-12-10T06:12:52.994Z",
  "version": "string"

DataShare URL

Below is the sample API detail for reference URL.

Sample Request URL

GET https://{base_url}/v1/datashare/get/mpolicy-default-abis/mpartner-default-abis/mpartner-default-abismpolicy-default-abis20210205062412BlQo0rJB

Sample Encrypted Response

The structure of the encrypted data downloaded from referenceURL in MOSIP 1.2.0 or later versions

The data downloaded would be URL-safe base64 encoded. Hence, after decoding the data will be in the below format. It will be divided into two Parts after splitting using #KEY_SPLITTER#.

Encrypted Key Data
KEY_SPLITTER
Encrypted Actual Data

Block 1

#KEY_SPLITTER#

Block 2

Block 1:

Block 1, i.e. the encrypted key data is again split into three parts,

  • The 1st part is VER_BYTES (version bytes). The Current version constant is set as VER_R2 and this is present in the first 6 bytes of Block 1.

  • The 2nd part is the Certificate Thumbprint i.e. the key identifier which is present in the next 32 bytes after VER_BYTES.

  • The 3rd part is the Encrypted Random AES Key, encrypted with the RSA OAEP - SHA256-MFG1. This constitutes the remaining 256 bytes of Block 1.

Block 2:

Block 2, i.e. the encrypted actual data is again split into two parts,

  • The 1st part is the random 32 bytes which will be used as AAD in AES encryption(first 32 bytes). From this 32 bytes AAD data, the first 12 bytes is IV/Nonce.

  • The 2nd part is the encrypted data which is encrypted using AES GCM PKCS5Padding.

Note: In Java 11, PKCS5Padding serves as a synonym for NoPadding in GCM mode encryption. Conversely, in Java 17, the synonym PKCS5Padding has been eliminated, and it is now mandatory to exclusively use NoPadding. Consequently, if data is encrypted using PKCS5Padding in Java 11, it will be decrypted with NoPadding in Java 17.

The structure of the encrypted data downloaded from referenceURL in MOSIP 1.1.5.5 or prior versions

The data downloaded would be base64 encoded. Hence, after decoding the data will be in the below format. It will be divided into two Parts after splitting using #KEY_SPLITTER#.

Encrypted Key Data
KEY_SPLITTER
Encrypted Actual Data

Block 1

#KEY_SPLITTER#

Block 2

Block 1:

Block 1, i.e. the encrypted key data is again split into two parts,

  • The first part is the Certificate Thumbprint i.e. the key identifier which is the first 32 bytes in Block 1.

  • The second part is the Encrypted Random AES Key which is encrypted with RSA OAEP - SHA256-MFG1. This constitutes the remaining 256 bytes of Block 1.

Block 2:

Block 2, i.e. the encrypted actual data is again split into two parts,

  • The 1st part is the Encrypted data, encrypted using AES GCM PKCS5Padding.

  • The 2nd part is IV/Nonce i.e. the last 32 bytes appended after encrypted data.

Note: In Java 11, PKCS5Padding serves as a synonym for NoPadding in GCM mode encryption. Conversely, in Java 17, the synonym PKCS5Padding has been eliminated, and it is now mandatory to exclusively use NoPadding. Consequently, if data is encrypted using PKCS5Padding in Java 11, it will be decrypted with NoPadding in Java 17.

Please note that for all the functional failures MOSIP sends a response code 200.

Identify

  • All Insert requests added to the queue earlier must be serviced by ABIS when performing an Identify request.

  • Identify request provides a 1:N comparison. The given input is compared either against the gallery passed or if the gallery is not specified the entire database.

  • The input for comparison can be provided by referenceID or referenceURL.

    • If the referenceID is given it is used as the preferred option. The given referenceID must be existing in the ABIS database else ABIS will throw an error.

    • If the referenceID is omitted or NULL and the referenceURL is passed the ABIS retrieves the biometrics provided in the referenceURL and compares the same against either a gallery or its database.

    • If in case, both referenceID and referenceURL are missing ABIS throws an error.

We are not using the referenceURL in Identify request for our current implementation. Hence, it will be an empty string for Identify request. MOSIP adopters can have customized workflows where the referenceURL can be used.

  • Identify requests should give to all candidates which are considered as a match based on ABIS thresholds.

  • This request should not match against referenceID that is not in the reference database.

  • The response now has a section for analytics that contains key-value pairs. Values can be JSON objects also. The contents of the analytics section will be agreed upon by the MOSIP adopter with the ABIS provider. Scores are also moved to this section and are not mandatory response parameters anymore.

  • Ordering or ranking of results is not explicitly specified and can be agreed upon between the MOSIP adopter and the ABIS provider.

  • The flags section of the request can be used to customize or control ABIS behaviour by sending specific key-value pairs.

  • "targetFPIR" or "maxResults" are examples of such flags that can alter ABIS behaviour. These are optional attributes for MOSIP during an identify request. MOSIP expects the adopters to define these parameters based on the accuracy expectations and workflow requirements. These can be set at the ABIS configuration level and need not be part of the individual request at all.

To give an example, please find the following calculation for targetFPIR - which is the error rate at which identification requests are expected to return a non-empty candidate list.

round (-10 * log10 (target false positive identification rate))

With this calculation:

Target False Positive Identification Rate
targetFPIR

1 in 1,000

30

1 in 10,000

40

1 in 100,000

50
