Roadmap

Milestone 0

• Simulate one user and associate a random home gps coordinate.
• Simulate random destination point within a radius of 1 km from home position
• Simulate a first self declaration from Home to one destination
• Get detailed navigation instructions and fill the Destinations field of the self declaration
• Simulate temporary declaration by pushing it to the distributed digital ledger, the Tangle

Milestone 1

Create a visualization tool to show the path

Milestone 2

• Create two users and two declarations with same destination point and time interval
• Use visualization tool to show the paths

Milestone 3

• Retrieve all declarations sent to specific address [Issue compromised content: https://iota.stackexchange.com/questions/2499/problem-retrieving-the-content-of-zero-value-transactions-from-the-testnet]

Milestone 4

• Create N users, N declarations in the same geographical area
• Push declarations to the Tangle

Milestone 5

Investigate how to determine if two citizens have shared a portion of the path

Milestone 6

Assume one user is tested positive for the CoronaVirus after some time

• Retrieve all declarations from the immutable ledger
• Simulate random positive test results citizen with universally unique identifier
• Create a Check function that given all retrieved declarations, and the id of a positive citizen returns a list of all possible contaminated users that have shared the same places at the same time and associate an number proportional to the exposure

Test the system

Clone the repository:

git clone https://github.com/GiovanniBalestrieri/autodichiarazione_2.0.git

Create and activate vitual environment:

cd autodichiarazione_2.0
python3 -m venv environ
. environ/bin/activate
pip install --upgrade pip

Install requirements:

pip install -r requirements.txt

Test the milestone you prefer. If you are interested in the output of mileston0:

pythone milestone0.py

When you are done. Deactivate the virtual environment and go back to normal life
