4. What type of data is processed by the Finoa Application
The Finoa app is designed solely for the verification and authorization of transactions, as part of a multi-factor authorization, to increase the security of Finoa's customers. All transaction data sent to the App is encrypted. The keys generated by the App are stored exclusively in the device used, e.g. mobile phone, and are not passed on. The communication of the App to authorize a release is encrypted without exception.
4.1 The processing of the Finoa App in detail
4.1.1 What data is accessed by the Finoa App
The list of tasks that the user is allowed to edit/view.
The list of public blockchain addresses of the customer.
To the "universally unique identifier", also called unique user ID, (hereinafter UUID) of the user.
4.1.2 What access rights does the app need
The App requires a one-time access right to the camera to get the QR code of the activation letter to be able to recognize the user. The App requires access rights to the Hardware Security Module (hereinafter HSM).
4.1.3 How does the Finoa app process data?
- At the start, an individual key in the HSM of the mobile phone is generated. This key cannot be read by the App, but can only be used for a series of predefined algorithms that are used (e.g., encrypting or decrypting with the key).
- Fingerprint / FaceID Scan initiates the authorization. The biometric data are available on the App, but are automatically generated by the operating system of the mobile phone.
- After the scan is complete, the App can decrypt data with the individual key (all data received from the server), and signatures (if a task is confirmed or rejected).
- The IP address of the mobile phone is also sent, but not processed by Finoa.
4.1.4 Deleting the collected data
If the App is uninstalled, the individual key is replaced by the operating system of the mobile phone deleted. The recorded UUID of the user is also deleted. Otherwise, no further data is stored.
All communication between mobile phones and servers is always encrypted. An encrypted connection is first established via HTTPS. The actual data during communication from the Finoa server to the mobile phone by means of individual keys is also encrypted. The encryption from the mobile phone to the Finoa server is done using TLS encryption.
4.1.5 Is the User behavior evaluated in the App?
The App does not evaluate user behavior.
