Sorry, that analogy is wrong. A change of key, or simply swapping all the variable names, is simply not a deemed a meaningful difference for copyright purposes. That does not mean one can copyright facts or logic.

Copyright protects only unique novel expression. Copyright will not protect a generic question requiring the subject to remember three items. One cannot copyright the fact that a person who cannot remember three items is probably impaired. But, copyright might protect the manner in which the question is phrased, or the manner in which the significance of various responses is explained. Still, it should be possible for someone to produce a copyright free replacement test based on the underlying facts of nature.

However, the limits of copyright protection do not prevent an aggressive copyright troll from asserting broader protection than they are entitled to. It can be expensive for a person who produces a free replacement test to defend their rights.

Its counterintuitive, and that is why it will work.
No one would think to look for confidential information "in the clouds?"

I've been shunning Facebook since before it was cool to shun Facebook. Am I cool now?

Not so far.

Google has lawyers. (Haven't you been paying attention?)

Since I won't even see the ad in the first place, it will appear to me that the site is broken and I will just move on to a site that isn't broken. These people have already lost me. For the people that do see the ad, I expect that the reaction of many people will be to immediately start seeking a circumvention. So, this escalation is just going to result in higher market share for ad blocking equipped browsers.

When pop-up ads got to be so obnoxious that people were abandoning IE for pop-up blocking browsers, even Microsoft put in a pop-up blocker. This proposal is so obnoxious that if it becomes widespread, you might even see Captcha circumvention built into the next version of Windows.

No, actually the fifth amendment does not protect you from being compelled to turn over a diary or other personal files. You can be jailed for failure to turn over papers and files even of a personal nature. You can be jailed for concealing evidence and refusing to permit access. In this respect, a password is no different than the location of a concealed diary, which you can be compelled to disclose.

You can not be compelled to admit guilt, but you can be compelled to provide access to physical or documentary evidence that may prove guilt.

Mine works fine and I am not returning it. I can only get the bars to drop by wetting my skin and squeezing firmly at the joint in the band. I won't be doing that when I make a call. You shoud activate yours and get some real world use out of it.
