I was reading an article that I admit surprised me. It seems that our Constitutional rights for self incrimination do not extend to the use of our fingerprints.
A Virginia court case had a judge rule that the police, who suspected incriminating evidence on his Smartphone, could legally force him to unlock the device with its fingerprint scanner, while you cannot be forced to enter your password.
So we now enter the conundrum of security versus privacy. What would/will you chose?
