JAR is the first biometric crypto-key for end customers: it turns your finger into what is needed to securely log in or register or access any kind of data (without letting any 3rd party access your fingerprint, ever). Its encryption is based on a 2048 Bit RSA-key pair, containing a public and a private key, where there private key is stored on a secured chip on the JAR, encrypted with your fingerprint.
The source code of the encompassing software solutions will be made open source, completely.
JAR (yourjar.de) is now on Kickstarter (https://www.kickstarter.com/projects/itisonyou/forget-passwords-use-jar). Every feedback or suggestions are highly appreciated!
