Trace Tees App
The Trace Tees App is a mobile application developed to support existing efforts to combat COVID-19 by enabling community-driven tracing of ‘Close Contacts’.
Keeping loved ones safe
Trace Tees supported Teesside’s effort to track and trace the spread of COVID-19 through the benefits of Bluetooth.
The app then uses Bluetooth and Bluetooth data is stored securely on a user’s phone. However, it will only share information if there’s a positive for COVID-19, for the sole purpose of contact tracing. Also, all Bluetooth data stored on a user’s phone is automatically deleted after 25 days.
Filled with features
- When phones with Trace Tees installed are nearby each another, they identify Close Contacts by exchanging anonymised proximity information using Bluetooth
- Trace UK uploads anonymised details of their Close Contacts to the app server by means of Temporary Exposure Keys (TEKs) that have been generated on their smartphones in recent days.
- When a user has tested positive for Covid-19, they enter this information in the Trace Tees app.
- TEKs do not give any indication as to the identity of a person who has tested positive, but TEKs from certain days can be matched with the Rolling Proximity Identifiers (RPIs) that a user’s smartphone has transmitted via Bluetooth that were received and recorded by other smartphones nearby.
- Several times each day, all active Trace Tees apps download the information of users who have tested positive for Covid-19.
- The distance and time of the user’s recent contacts are calculated and identifies Close Contacts who are at potential risk if the contact has taking place for more than 15 minutes (TBD) and less than 2 metres (TBD).
- Trace Tees will notify Close Contacts and provides recommendations as to how the user should proceed (e.g. self-isolate)
- Trace Tees could also be configured to automatically link user’s Covid-19 test results. By means of QR codes or similar on test samples, to alert Close Contacts without requiring the user to enter this in the Trace Tees app. This would require additional development time and cost.
