Contact tracing app - smoke and mirrors?

You know the contact tracing app that governments think will be a great idea. You would think so, until you look at how it would work with a critical view.

Then it completely falls apart. If you're thinking of using one, don't bother. Read this article for a great explanation why from one of the leading authorities on information security, Bruce Schneier.

Some of the comments are great too.

[Update] It has come to my attention that Google and Apple are jointly working on an app that could solve many of the problems in Schneier's article. But for now, the apps created by our local governments likely do not measure up to the same standard as the one being worked on by Google and Apple.
