Philly Date Safety (PDS) is design to assist first and blind date users within the central Philadelphia area (first supported city). It uses a four-part redundancy system by utilizing a dedicated server’s algorithm, the phone itself, GPS locational captures designed in a simi-confidential way and a spoof prevention system to send an alert regardless of the phones status. In addition to this, the user interface was designed to assist users with visual and mental disabilities as well as run the tutorial in five spoken languages.
Despite the complexity of the backend, the frontend of the app is extremely simple and can be understood in just five simple steps. In addition to this the user interface was designed to assist users with visual and mental disabilities as well as run the tutorial in five spoken languages.
The system works as follows:
The app takes GPS location snapshots called a “Capture Point” of the user at set timed intervals.
These locations are then stored on a high level encryption web server that the app runs off of as well as the app it self.
When these “Capture Points” are taken, a notification alerts the user that they must enter their “Safety PIN” to confirm they are safe.
These alerts are connected to “Designated Buddies” friends of the user that have agreed to aid them in the even an alert is sent to them.
Should the user fail to enter their “Safety PIN” the alert is sent to the “Designated Buddies” with the “Capture Points” from the last 48 hours. The “Designated Buddies”” can then choose how to proceed with the alert.
