Our application is designed to look like a familiar mobile chat application, with the pertinent details about secure communication highlighted while and most technically of the technical details are abstracted away. We felt that most of the existing solutions available were not usable by the vast majority of the population, and wanted to design something that would be secure , while making encrypted communication more accessible. Thematically, we went for a very minimalist UI to further emphasize our goal to simplify encrypted communication. At a high level, the application is broken into 4 tabs, each of which provides essential functionality to the application.
GUI Section | Screenshot | Design Commentary | |||
---|---|---|---|---|---|
Login |
| The login screen was designed to ensure the application preserves user security. It appears any time the application loses focus, to ensure that anytime the phone changes state, turns off, or otherwise may potentially enter an unsecure state, a password must be entered. | |||
Inbox |
| The inbox is designed to look and feel like a traditional text message/chat mobile application so that learnability is made easier. | |||
Contacts |
| The Contacts Section screen is where users can browse and edit the users to whom they expect to communicate securely with. | |||

My Identity |

. There were debates on how much data to allow the user to see/mess around with in terms of contact data, and we settled on trying to keep things simple and uncluttered with lots of contact data. | |||||
My Identity |
| 'My Identity' is a simple screen that shows the user's profile data, and a large 2d barcode that can be used to physically share their encryption key with another user of the application. | |||
Settings |
| This is a basic settings screen with gives a place for the user to modify application settings. This is designed much like any typical settings screen, and as of now only allows the user to edit their password. | Settings |
