My Smartphone Hears Voices - And Transcribes Them

It is said that idiots are easily amused. By that criterion I am one. I am easily amused by the degree to which speech recognition software has improved from my college days 47 years ago to the present. It still has a few problems even today, but I am managing to write this post using the Google speech to text software built-in to this phone.

And that pleases me more than you can imagine, or at least more than words can express. I am having fun with a technology for the first time in years!

ANNOTATION from the desktop's keyboard: my dictation was halting, as you might expect of someone who is not by training or nature a dictator. But there were only two errors I could not easily correct by speaking rather than typing: one was the sentence "I am one"; the s/w was absolutely determined to change the "one" to the digit "1" no matter what I did. One time it even visibly transcribed it as "one" and then visibly changed it to "1". (sigh!) The other had to do with inserting explicit newlines. The s/w recognizes some punctuation and a few formatting characters when their names are spoken, and "newline" is one of them, but something about my Texas accent must have thrown off the recognition algorithm: sometimes it inserted a Unicode/ASCII newline character; sometimes it rendered it "Near line" or something even more unrecognizable. Even so, there were no more transcription errors than I learned to expect from the cheeky and uncooperative keypunch operator in my first job right out of college. (sigh again!)

Your Cell Phone: Hacked By Governments, Handed Back To You With ‘Enhancements’

(This is several days old, but I suspect it will be painfully significant for literally years. - SB)

Jeremy Scahill and Josh Begley at The Intercept:
AMERICAN AND BRITISH spies hacked into the internal computer network of the largest manufacturer of SIM cards in the world, stealing encryption keys used to protect the privacy of cellphone communications across the globe, according to top-secret documents provided to The Intercept by National Security Agency whistleblower Edward Snowden.

The hack was perpetrated by a joint unit consisting of operatives from the NSA and its British counterpart Government Communications Headquarters, or GCHQ. The breach, detailed in a secret 2010 GCHQ document, gave the surveillance agencies the potential to secretly monitor a large portion of the world’s cellular communications, including both voice and data.

The company targeted by the intelligence agencies, Gemalto, is a multinational firm incorporated in the Netherlands that makes the chips used in mobile phones and next-generation credit cards. Among its clients are AT&T, T-Mobile, Verizon, Sprint and some 450 wireless network providers around the world. ...

And now if you'll excuse me, I have to charge up my tracking device; otherwise the government might miss something I say or email or text or snap or...

Cell Phone Owners Should Prefer Passcode To Fingerprint Protection

In America, you can't legally be forced to testify against yourself, or forced to reveal a cell phone passcode. But according to a judge in Virginia, a cop can commandeer your finger to accomplish the same thing. Here's Megan Geuss at Ars Technica:
A Virginia Circuit Court judge ruled on Thursday that a person does not need to provide a passcode to unlock their phone for the police. The court also ruled that demanding a suspect to provide a fingerprint to unlock a phone would be constitutional.

More than just the phone can be bent
The ruling calls into question the privacy of some iPhone 5S, 6, and 6 Plus users who have models equipped with TouchID, the fingerprint sensor that allows the user—and ideally only the user—to unlock the phone. It is possible for users to turn TouchID unlocking off and simply use a passcode, and Apple has provided certain extra protections to prevent TouchID privacy issues—requiring the entry of a passcode if the phone hasn't been used in 48 hours, for example. But if a suspect simply uses TouchID to open their phone, police could have a window to take advantage of that when apprehending them.
[/sigh] It's always something, and seldom something good. The assertion of courts is that knowledge from testimony (e.g., telling police a passcode) reveals the suspect's mind and thus cannot be compelled under the 5th Amendment... but a fingerprint is just a biometric, traditionally collected in police investigations. Once again, the law uses a quirk of technological change to enforce a distinction without a difference. Self‑incrimination, here we come.

Mysterious Cell Towers Infiltrate Phone Companies' Systems

Who built them? Who owns them? What might they do to your cell phone, and on whose behalf? Why are many of them near military bases? Peter van Buren at FDL: The Dissenter discusses the matter, in terms that are necessarily speculative given how little is known at present.

I can't help thinking of Sir Terry Pratchett's later Discworld novels and their clacks, a mechanical optical semaphore long-distance communication system that is the focus of many intrigues, plots and assassinations. If you're not reading Pratchett's Discworld novels, you're missing one of the most thoroughly enjoyable series out there. Call it s/f, fantasy or humor; you'd be correct with any of those categorizations. The first novel in which I remember the clacks appearing is Going Postal, and reading the later novels won't spoil the earlier ones if you choose to read about the clacks out of publication sequence. (Correction: Wikipedia says the first such novel is The Fifth Elephant.)
