Inspiration
We noticed a lack of current evidence gathering apps for domestic abuse victims that are both discreet and secure that also include attaching photos and videos.
What it does
Our app allows you to create a case through a time line based database. It allows you to discreetly log into a secret part of a calculator app that allows you to build your case against your abuser. You can add and revise a daily log of your abuse that is streamlined into a revised JSON file and videos/photos in a database.
How I built it
We used android-studio, SQLcipher, an open source calculator app, and other tools and references.
Challenges I ran into
Serializing all the photos into bitstreams which we can then encrypt is difficult.
Accomplishments that I'm proud of
We built a pretty cool model for an overall concept of security through cryptography and steganography.
What I learned
How to use SQLcipher, data serialization of images, displaying images, attaching stuff to JSON files, etc.
What's next for ProCalc
-Finish implementing the secure database with salt extended passwords, hidden mutated datastore. -Panic button that kills the app and any traces in memory and sends the database to a spideroak account.
