The application covers the following features :

• Enter kiosk mode from the application
• Exit kiosk mode with an OTP (One-time password) from Google Authenticator.
• Modify the URL of the website hosting the video
• Claim the tablet and modify the website of the tablet online
• Secret touch command to open OTP pin (touch screen 4 times in the right pace)
• Viewer statistics

Backend configuration concept

In the encryption we use PBKDF2 to generate a key from a passphrase and use this key to encrypt the config with AES. Because there is no authentification for storing something in the database, a tablet replaces the online config with the local one when it can't decrypt it.
