Java 17
Encryption and MDMS services are running
PostgreSQL server is running
Redis is running

Key Functionalities

Store, update and search user data

Deployment Details

Setup the latest version of egov-enc-service and egov-mdms- service
Deploy the latest version of egov-user service
Note: This video will give you an idea of how to deploy any Digit-service. Further you can find the latest builds for each service in out latest release document here.
Add role-action mapping for APIs
Note : This is a sample JSON file containing role-action mapping , If you don't have any of the master data setup yet you can you this to create on for you and then add all these files and start making changed in your repo.

Integration Details

Integration Scope

User data management and functionality to log in and log out into the DIGIT system using OTP and password.

Integration Benefits

Providing the following functionalities to citizen and employee-type users

Employee:

User registration
Search user
Update user details
Forgot password
Change password
User role mapping(Single ULB to multiple roles)
Enable employees to login into the DIGIT system based on a password.

Citizen:

Create user
Update user
Search user
User registration using OTP
OTP based login

Integration Steps

To integrate, the host of egov-user should be overwritten in the helm chart.
Use /citizen/_create endpoint for creating users into the system. This endpoint requires the user to validate his mobile number using OTP. First, the OTP is sent to the user's mobile number and then the OTP is sent as otpReference in the request body.
Use /v1/_search and /_search endpoints to search users in the system depending on various search parameters.
Use /profile/_update for updating the user profile. The user is validated (either through OTP-based validation or password validation) when this API is called.
/users/_createnovalidate and /users/_updatenovalidate are endpoints to create user data into the system without any validations (no OTP or password required). They should be strictly used only for creating/updating users internally and should not be exposed outside.
Forgot password: In case the user forgets the password it can be reset by first calling /user-otp/v1/_send which generates and sends OTP to the employee’s mobile number. The password is then updated using this OTP by calling the API /password/nologin/_update in which a new password along with the OTP is sent.
Use /password/_update to update the existing password by logging in. Both old and new passwords are sent to the request body. Details of the API can be found in the attached swagger documentation.
Use /user/oauth/token for generating tokens, /_logoutfor logout and /_details for getting user information from the token.
Multi-Tenant User: The multi-tenant user functionality allows users to perform actions across multiple ULBs. For example, employees belonging to Amritsar can perform the role of say Trade License Approver for Jalandhar by assigning them the tenant-level role of tenantId pb.jalandhar.
Following is an example of the user:

{
        "id": 24226,
        "uuid": "11t0e02b-0145-4de2-bc42-c97b96264807",
        "userName": "xyz",
        "name": "abc",
        "mobileNumber": "9999999999",
        "emailId": "abc@gmail.com",
        "locale": null,
        "type": "EMPLOYEE",
        "roles": [
            {
                "name": "Employee",
                "code": "EMPLOYEE",
                "tenantId": "pb.amritsar"
            },
            {
                "name": "TL Approver",
                "code": "TL_APPROVER",
                "tenantId": "pb.jalandhar"
            }
        ],
        "active": true,
        "tenantId": "pb.amritsar"
    }

If an employee has a role with statelevel tenantId they can perform actions corresponding to that role across all tenants.

Refresh Token: Whenever the /user/oauth/token is called to generate the access_token along with access_token, one more token is generated called refresh_token . The refresh token is used to generate a new access_token whenever the existing one expires. Till the time the refresh token is valid, users will not have to log in even if their access_token expires since this is generated using refresh_token. The validity time of the refresh token is configurable and can be configured using the property: refresh.token.validity.in.minutes

User Data Privacy

Since User service handles PII (Personal Identifiable information) encrypting the data before saving in DB becomes crucial.

DIGIT manages these as security policy in Master Data which is then referred by encryption service to encrypt the data before persisting it to DB.

MDMS Configuration For Security Policy

There are two security policy models for user data - User and UserSelf.

User model

attributes contains a list of fields from the user object that needs to be secured and the field
roleBasedDecryptionPolicy is an attribute-level role-based policy. It defines visibility for each attribute.
User security model is used for Search API response

UserSelf

It contains the same structure of security policy but the UserSelf is used for Create/Update API response.

The visibility of the PII data is based on the above MDMS configuration. There are three types of visibility mentioned in the config.

PLAIN - Show text in plain form.
MASKED - The returned text contains masked data. The masking pattern is applied as defined in the Masking Patterns master data.
NONE - The returned text does not contain any data. It contains strings like “Confidential Information”.

Plain Access Request

{
  "RequestInfo": {
    "plainAccessRequest": {
      "recordId": "d5ee3d45-13a1-4aa5-bd86-9b8dae34b900"
      "fields": [ "name", "mobileNumber" ]
    }
  }
}

Any user can get plain access to the secured data (citizen’s PII) by requesting through the plainAccessRequest parameter. It takes the following parameters:

recordId - It is the unique identifier of the record that is requested for plain access.
fields - It defines a list of attributes that are requested for plain access.
