Blockchain for data tracking

MAR-MAY 2023

Exploring blockchain technology in the realm of data privacy and protection. Looking at different use scenarios, and delving deeper into the data privacy ecosystem to design interventions that can utilize the characteristics of the blockchain ledger system.

Key words

Futuristic design, design research, technology utilization, communication design

Project duration

10 weeks 


Can blockchain be used
for data privacy?

At the beginning of the project my knowledge of blockchain was virtually non-existent. I am someone who doesn't stand for crypto or NFTs and I still go by it. Nevertheless, I've come to view blockchain technology as a treasure trove of potential one that should be fervently embraced by a multitude of industries. The power blockchain can give the normal citizen is something that amazes me.

I am grateful to Mr.Praful Chandra for being the catalyst that opened my eyes to the manifold possibilities that this technology offers. This project presents my exploration of blockchain for data protection and tracking. I wouldn't say my final idea is complete, rather it is an ongoing and evolving work in progress.

The challenge

In the current scenario, the normal user is not entirely aware of what information they put out in the Internet of things, what is owned by them and what is not.  This information could be artwork, video content, or other personal information too.

There is no current system that efficiently controls and tracks to whom a user's data is getting shared to. Secondly what data is shared to whom.  Another aspect of the problem is the inability to take back the data given when it is not needed anymore.

Aim and Objectives

Provide users the ability to take back personal data given to a business.

Educating and communicating the user about data market space. Creating awareness about data protection.

To prevent third party stakeholders from connecting a user's digital identity with their physical identity.

A step towards preventing concentration of citizen data into the hands of a foreign entity.

A platform to track who is accessing user data in the digital space to manage digital logins.

Improving communication between citizens and the government and government services.


My journey and thought process



  • Understanding Web3 and blockchain.

  • Delving into use cases of blockchain

  • Gaining insights on the current scenario with digital wallets.

  • Conduction user surveys.

  • Market research and mapping.



  • Mapping ecosystem

  • Understanding user insights

  • Connecting the dots, identifying gaps and patterns. 

  • Bridging current scenario with proposed scenario.

  • What why how of the problem



Drafting the problem statement. Storyboarding

Creating user stories. 

Mapping task flows.

Communicating the concept to users.

Building prototype of intervention.

Presenting Digilog

  • An aternative login system that uses the web3 format of public and private keys.

  • A system which adopts the blockchain feature of record keeping to track data shared.

  • A web3 application to track logins and data shared(data transactions)

  • A digital document and ID wallet that is equivalent to a physical ID, maybe a future version of Digilocker.

Do give this a watch. Pictures speak louder than words.

So what is a smart contract and how does it work?


How does it work?

A Smart contract is an automated program that is self - executed when predetermined conditions are met.

Visualizing interactions
