PQR

Protected QR Codes: Open, yet private

Comment

Inspiration

Lots of thinking

What it does

The app creates networks for QR codes. This allows users to create private events with signs (codes) that no-one else can decode but the invited guests. PRQ could also lead to further games (Treasure Hunts?) and codes where every person would see different results from the same code. Imagine test scores posted that contained everyone's scores, but only showed your own.

How I built it

I used the Firebase API to authenticate users and keep records of all QR Codes. Then, local iOS API's took care of recognizing the codes, creating the codes, and image manipulation. I also used sketch to design my mockups and some UI tools from Danil Gontovnik on Github.

Challenges I ran into

  • I had many mess ups with observing changes in the firebase API rather than requesting them.
  • I had a hard time devising how I would model my whole backend on JSON
  • Child view controllers

Accomplishments that I'm proud of

  • It works!!!
  • First solo hackathon project!!!

What I learned

  • How to work with AVFoundation
  • Firebase
  • The power of QR codes
  • iOS Paginations

What's next for PQR

  • Multiple people see different things
  • Backup website for people who don't have the app
  • APP STORE?!
