German startup firm Jar has developed a compact personal fingerprint reader that connects to devices using their audio jack, saying the encryption is so strong it would take a hacker 6.4 quadrillion years to access the user's data.The Jar device, which is small enough to be attached to a keyring, uses encryption based on a pair of 2048 bit RSA keys. It would be used on smartphones and laptops to login to websites.The company has launched a crowdfunding initiative for the device, with a goal of 100,000 euros (US $108,000). It will be available in two sizes: 42 x 42 x 4 mm and 36 x 36 x 3.8 mm at a price of around 99 euros.”We have designed JAR to feature an audio connector, because virtually every device that can connect to the web has an audio jack. Besides that we are developing an API, that will allow nearly every website to implement 'Login and Registration with JAR'”.The developers note that fingerprints will be stored encrypted only on the JAR, adding that they are building the operating system on protected systems in Germany, guaranteeing that there are no backdoors in our code.
