Nation-Wide Facial Recognition


Indian child labour activist, Bhuwan Ribhu, points out there are over 3,00,000 missing children in the country. And there are over 1,00,000 children in various institutions. Matching them manually is obviously a practical task. In July this year, he launched a pilot program to match the digital databases using facial recognition technology. The outcome was very good:
“We were able to match 10,561 missing children… They are currently in the process of being reunited with their families.”

Given the severe shortfall in police (144 officer per 1,00,000 citizens) as opposed to, say, the EU (318 per 1,00,000), India needs to try and find different ideas to bridge the gap. Including, as it turns out, turning to facial recognition technology.  Delhi adopted it in 2018, along with Andhra Pradesh and Punjab.

And now the central government wants to expand the scope:
“It wants to construct one of the world's largest facial recognition systems. The project envisions a future in which police from across the country's 29 states and seven union territories would have access to a single, centralized database.”
What would be the source of photographs for this database? Mugshots of criminals, obviously. Also artist sketches of suspected criminals. Add to that passport photos and images from the increasing number of CCTV’s.

As you might have imagined, the idea is to expand the usage beyond just the police:
“Security forces would be equipped with hand-held mobile devices enabling them to capture a face in the field and search it instantly against the national database, through a dedicated app.”

In October, bidding was opened for this project. Pre-bid meetings with prospective vendors in July included discussions on topics like “whether it should be able to identify people who have had plastic surgery”. Given the lack of experience in such matters amongst Indian companies, we might need to tap into foreign companies. A local player has been mandatory in whatever consortium is picked. But that raises concerns of national security and espionage by those foreign companies.

Experts believe this is going to be a very challenging project, especially the centralized database aspect. On the other hand, we did build the Aadhar system, so who knows? Others say the number of CCTV’s are too small today to make such a project meaningful. Then again, once you have such a system, CCTV feeds could be made mandatory in more places, and it may get added in phases into more and more public places. London and Shanghai have lots of such feeds, but not the whole of UK or China, so perhaps we’ll start with the major cities too.

Delhi, for examples, started the project to install 3,30,000 new cameras across the city. They cite improving the safety of women as the driver. The government plans to add such feeds in all stations in the country by 2021.

There are concerns over lack of data protection laws in the country. Privacy concerns are another issue. And as always, there is the fear it would be used against minorities. And if it were to get linked to Aadhar, it might end in a “total, permanent, surveillance state”, worries Apar Gupta from an NGO. So yes, it is going to need a balancing act:
“Caught between the need to improve its policing outcomes and to protect its citizen's privacy, India will be walking a tightrope when it comes to building its national facial recognition database.”

I think we need to be pragmatic: we are not rich like the West, we don’t yet have all the right laws on privacy, but staying put and doing nothing until those things happen first is not an option either. So we move along, and adjust along the way.

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
