How do I ensure the privacy of the biometric data sent?
Privacy is one of the key points in this kind of applications. For this reason the platform includes several security levels:
• In the communication link layer: WPA2 for Wifi.
• In the application layer: by using the HTTPS (secure) protocol we ensure a point to point security tunnel between each
sensor node and the web server (this is the same method as used in the bank transfers).
5.3. MySignals Mobile APP
The Bluetooth connectivity may perform direct communications with iPhone and Android devices without the need of an
intermediate router.
The first time a user starts MySignals application, it will be needed a setup assistant to configure all aspects related to MySignals
configuration like user name, password (already set in our back end), profile, WiFi settings and MySignals selection. We will
create a setup assistant with straightforward screens with all field and information to guide the user through this assistant.
Design department had provided some sketches with an idea about how assistant can be done, these images represent each
step in our assistant:
Figure : MySignals APP configuration screen
An account can have one or more MySignals devices, this is why an user can purchase more than one device. Then we must
create am MySignals manager to provide a list of devices and perform some basic operation over them.
This manager can add/delete/modify/select an MySignals device. This information should be synchronized with cloud to get all
devices up to date for a given account.
As each MySignals is tied to each single user, we should download a list of devices each time an user log in, this way we do not
mix MySignalss from different accounts.
In the first screen you can configure the operating mode: BLE, WIFI or standalone.
