Hello HN, we're developing a new behavioural system for authentication.<p>We've released an app for Android that tracks the user's behaviour when entering a pre-set PIN. You can find it here: https://play.google.com/store/apps/details?id=com.idenux.invisilockexperiment<p>We will track behavioural features such as typing speed and pressure, along with geolocation. There are more details in the application description.<p>Any participation and feedback on the app and approach in general is greatly appreciated. Thank you for the help!
