| # Profile.io: privacy preserving identity, nationality and age verification | |||
|
|
|||
| Using a profile.io user's indentity verification KYC results to prove user's adult verification and/or nationality without revealing personal data by using ~~Aztec Connect~~ Noir circuit ZKP. Scoping service for third parties to verify such information privately, either through profile.io/verify or their own user flows (eg. exploring potentially using Frames.js). | |||

Is it just using the Noir DSL (Domain Specific Language) and tooling, or also the aztec.network?

This is for end-users who interact with UI that uses aztec tech behind scene.

| The plan is to use ZKP and Aztec Note when user inputs his/her identity including age then the user can use it when the age verification is required without revealing details. |

Will be worth digging a little deeper into what you want to be public/private in terms of inputs and state.

I discovered that using Aztec Connect is not recommended. Therefore, I had to change the plan. I will update the readme.

| 1. The FE has a "verify" button and when verifier clicks that button -> Calling Aztec contract to process target user's age verification -> FE shows whether the user is an adult or not on the UI. | ||

For (a) and (b) below, you should be able to find relevant information in the docs. For (a), I think you could even just "Ask Aztec AI" (appears in the bottom right corner of the docs).

I could find the answers although I have many other questions still. I will update the readme.

Would be worth understand where the assumptions begin. Eg, are you assuming a public NFT has a verified age indication, and you want to use that? That is, proof of possession of that NFT, without revealing which NFT?
Or maybe the assumptions start somewhere else

My idea is user has a private NFT that contains user's personal info such as age, nationalities, eye colour, etc as a note.
So only the user can see the note by default.
When a verifier (another user) requests user's info (ex: isEuropean? isAdult? isFemale?), the NFT holder sends to the verifier by encrypting with verifier's address without revealing other sensitive info.
The verifier is the only one who can open and see the info.
But that's my theory and I am on the way to figuring out how to implement with Aztec tech.

love what you guys have done here! could you please update the PR title and description with a quick summary of your project? also would love if you could add all your code, esp relevant frontend code if possible. You'll need it for submission and would love to take a look beforehand 🙏🏽 |
tabledK
changed the title

@0xrafi I added a simplified version of the frontend. Feel free to check :) |

could you please add a relevant description to the PR? also ensure all code is inside of your named project directory and move the .gitignore file into your project folder |
