Hello Cypherpunks! As many of you will likely know, Microsoft has recently made public a release date for Windows 10 and has been testing the platform as part of the "Windows Insider" program. With this update comes a number of seemingly unoriginal [1], but nonetheless interesting features, such as "Cortana", Windows' "truly personal" assistant (only to be available in a handful of countries) and "Windows Hello", a biometric authentication system allowing the use of the face, iris, or finger for access [2]. What changes in Windows' security are expected to take place? Will systems such as Windows Hello leak uniquely identifiable biometric data, despite a planned increase in security [3]? What could perhaps be done to limit the risk of using systems such as a cloud-based, personal assistant that is able to access most of a person's internet-connected devices? Thankyou very much, Endless [1] It seems that Windows 10's flagship features such as biometric authentication have already been available on a number of other platforms for quite some time, not to mention the fact that the name "Cortana" was used as the name for an artificial intelligence character in the popular "Halo" game series (The name seems to be have been used without violating intellectual property laws, as Halo, having been originally developed by Bungie, Inc. is now a subsidiary of Microsoft Studios).
