Address Update

Problem Statement

Address Update Challenge in Urban Areas

• As per the current policy, Aadhaar requires a supporting Proof of Address (PoA) document or an Introducer who can lend his address to update the aadhaar.
• You are required to provide an innovative solution using technology that will help in overcoming your challenge to update the aadhaar.
• For the solution, you will interface with your landlord in an online manner using a smartphone or online portal to request his address (known as Introducer and performing the role of the donor).

Solution Approach

We have added 3 functionalities to solve the above problem

Authentication using Aadhar number

• User need to login to the application using their aadhar number and otp will be sent to the mobile number added to that aadhar number.
• After Login user will receive their sharable code the he/she can share with anyone. (For security purpose we are not allowing them to share aadhar number)

Request Address from requester side to lender

• In this flow user need the sharable code of lender.
• Using sharable code of lender, requester can request him/her for their address.
• After the approval of address from lender, requester will get notification about the approval, thereafter he/she can do minor modification in the address provided by lender and set it as his/her address.

Accept and Approve Address update from lender side

• When requester make an Address request to the lender, lender will get notification about the request.
• In the request he will be able to see name and contact number of requester for verification.
• He can accept or reject the request.
• After rejection, a notification will be sent to requester about the rejection he received.
• After clicking on approve, lender will have to fill the captcha and thereafter he/she also need to fill the otp he/she will receive on his/her mobile number added in the aadhar.
• After verification through otp and ofline ekyc of lender will be shared with the requester in the encrypted form.
• Requester will download the offline ekyc, decrypt it and use the address of lender.

View sharable code.

• User can access their Sharable Code in the app.

NOTE:

• All the data sharing are happening in the encrypted format.
• We are not storing the personal data anywhere
