Crime Fighter Google

Recently, Google alerted the authorities when its algorithms detected that a Gmail user was transmitting child pornography images. The cops then went on to arrest the man. A good thing, no doubt. But it makes one wonder how Google found the image? Are they opening every attachment in every mail? Don’t worry, it’s nothing that invasive. They use an algorithm created by (hold your breath) Microsoft!
“Google makes use of Microsoft's PhotoDNA technology to scan emails, and calculate a mathematical hash for an image of child sexual abuse that allows it to recognize photos automatically even if they have been altered. The tech is now also used by both Twitter and Facebook, after Microsoft donated it to the NCMEC in 2009.”`
But is this a slippery slope, wonder others? John Hawes, cyber security consultant asks:
“There will of course be some who see it as yet another sign of how the twin Big Brothers of state agencies and corporate behemoths have nothing better to do than delve into the private lives of all and sundry, looking for dirt.”
Or as Kevin Roose puts it:
 “Google's creepy data practices have helped police catch who they think is an even bigger creep.”

No wonder then that Google issued a statement clarifying what it does and what it does not do:
“It is important to remember that we only use this technology to identify child sexual abuse imagery, not other email content that could be associated with criminal activity (for example using email to plot a burglary).”
I kid you not. That is what Google said!

Matt Buchanan had a field day based on Google’s clarification. He wrote:
-         “Gmail: a secure choice for plotting assassinations and most other crimes since 2004.”
-         “A reminder that Google Precog is only in effect for certain crimes”
(In case you were wondering, “precogs” were the 3 psychics in the Tom Cruise movie, Minority Report, who could predict a crime before it happened.)

There is no right answer in this debate. As Kevin Roose said:
“Clearly, if perfect technology to detect child porn in transit exists, there's a strong moral case for using it. The big question, though, is where Google should draw the line.”

Now, if only we had a precog to predict where Google will draw the line...

Student of the Year

Image
As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of
