Citizens' Issues
True lies of biometric technology in Aadhaar enrolment

Let’s ask the professors UIDAI cited in its latest report: Do you agree with UIDAI’s assessment of Aadhaar? Do you share their confidence in the project? Did UIDAI ask you in advance, before using your name for their marketing purposes?

The Unique Identification Authority of India (UIDAI) have been accused of making false claims about the reliability of the biometrics that its unique identification number (UID) or Aadhaar scheme relies on. The report released earlier this week by UIDAI is in response to those criticisms.

UIDAI say that “… based on the analysis, it can be stated with confidence that UIDAI enrolment system has proven to be reliable, accurate and scalable to meet the nation’s need of providing unique Aadhaar numbers to the entire population. It is now safe to conclude that the system will be able to scale to handle the entire population”. But that is mere assertion, it begs the question, they would say that, wouldn't they.

They need independent and respected biometrics experts to agree with them, if this report is to boost confidence in UIDAI’s abilities. They mention several names. The casual reader may assume that these named experts all agree with UIDAI’s conclusion that Aadhaar will work. It would be instructive to ring them up and ask them directly for their opinion.

Does Professor John Daugman, for example, agree with UIDAI when they say that “… although [the false positive identification rate of 0.057%] is expected to grow as the database size increases, it is not expected to exceed manageable values even at full enrolment of 120 crores”? It seems unlikely—Professor Daugman is the man who first pointed out that any attempt to prove uniqueness in a large population of biometrics must drown in a sea of false positives, please see

And does Professor Jim Wayman, for example, agree with UIDAI when they say that “… based on the [receiver operating characteristic] model, the UIDAI expects the accuracy of the system to remain within the same order of magnitude as reported above. Hence it can be stated that system will be able to scale to handle the entire population without significant drop in accuracy”? It seems unlikely—Professor Wayman is the lead author of a paper which concludes that biometrics is a discipline out of statistical control, the results gathered so far tell you nothing about what to expect in future, please see

If the two professors agree with UIDAI and renounce their earlier statements, well and good.

But if, on the other hand, they say that they have no reason to believe that UIDAI is right, they have not had a chance to assess the evidence that UIDAI claims to have, they do not understand why UIDAI has mentioned their names, then this schoolboy attempt to justify UIDAI’s waste of public money will fall humiliatingly flat on its face.

Professor John Daugman has raised some serious issues and we can trust just a single authority UIDAI for such a important and big project we must scale the project to many authorities and also monitor them closely because identity theft can be a big issue and threat to security of India. Government must think about it instead of getting overwhelmed by the concept.

A discussion on biometric technology could be of some academic interest. I am puzzled why this is a continuing focus in the debate here. Several other aspects are perhaps more important. For example, 'Headlines Today' TV reported just now (Feb 3, 8.45 PM) the news of the Agriculture Minister's goons raping a rape witness. Another report today from Canada is on a bribe allegation against the former Aviation Minister. A chief minister is under investigation by a Special Team appointed by the Supreme Court. A former Telecom Minister is in jail. The Supreme Court has asked the allegation against the Home Minister to be decided by the trial court. Are these the people who would be in charge of the biometric database of the people?
If UID is meant for ensuring that welfare benefits reach the poor, beneficiaries, why is UIDAI enrolling those ineligible for such subsidies? How would the database be used for the poor? Will authentication be done at the 600,000 ration shops at delivery? If not how would UID be used to ensure the poor receive the rations? UIDAI and the advocates of the UID would never answer these and many such questions. Why waste time on technology, if issues of use and implementation are not included in the debate?

Mathew: You are absolutely correct. The focus must be on the use or applications of Aadhaar. And yes, as PDS adopts Aadhaar, duplicates will first be reduced. Then each state PDS department has to evaluate eligibility of ones still on the list. In case of LPG cyclinder, trial is already underway where each delivery is verified by authenticating the resident with Aadhaar number.

Ram Dasji....Here is an eyeopener for everyone who is (still) under the impression that UID will resolve the PDS and other supply problems.

Thank you for pointing out another reason to use a system that works. UID is already being used for gas cylinder delivery in Karnataka and for MGNREGS payments in Jharkhand. We can debate as much as we like. Those who want to move forward are already going ahead.

Critics Argument goes like: We don't trust UIDAI. Therefore their numbers are bogus. Therefore they are fraud/liers etc.
Perfect tautology.
1. UIDAI results are the same across PoC, 100M DB and are consistent with other large accepted NIST like results.
2. UIDAI has presented results in over 6 papers in the the most prestigious biometric conferences.
3. UIDAI hired world's top most biometric experts in design and testing.
4. Two good multimodal biometric will generate 100 to 10,000 better results than single mode biometric. You will find this in any introductory biometric textbook.
Nothing is out of ordinary except India is able to execute a project efficiently, within schedule and in reasonable budget.

Mr. Moss, if you want to check out facts, please attend International Biometric Conference in Delhi in March 2012. You can check your statistics with 200 biometric experts including Daugman and Wayman.

We asked some relevant and reasonable questions to Aadhar and no answers were forthcoming. It is then that distrust began, not before. Where is the feasibility study, where is the cost benefit analysis ? Where is a full life cycle PoC ? Does authentication work at all? How does Aadhar handle fake fingerprints ? There are no answers from Aadhar for these questions even now. Then there are other questions of privacy, linking of database, and how Aadhar will plug leakages. Again no answers. Then there is the freedom v/s authoritarian issue, no answers forthcoming. Then there is the question as why public money is used for doing something that is needed by private companies for marketing. No answers forthcoming. Questions of security of the database, and why a centralized one. No answers forthcoming. What happens if someone's biometric is stolen ? No answers forthcoming. Heck, biometrics is already stolen by fake enrollers. I would go on and on. Will any private company if it were the customer of Aaddhar would pay for such junk? But then we know what happens in Indian govt. Hope you read about cancellation of 122 licences by Supreme court. This is called "Andher Nagari chowpat raja". India is for sale and loot.

Dear Ram
Good to hear from you again,
I went to Biometrics 2009, a three-day biometrics conference and exhibition here in the UK and facts were hard to find,
It was a groupthink event. Sealed off from the outside world, all the delegates thought that everything was rosy in the biometrics garden, and each one reinforced the other’s unfounded confidence. So, no thank you, I shan’t be in Delhi next month.
Re your facts, the FPIR we were all pointed at in the PoC report was 0.0025%. Now, in the enrolment report, it’s 0.057%, 22.8 times worse. Consistent?
Aadhaar is sui generis. UIDAI won’t learn from the experts and the textbooks, it’s the other way round.
And no-one will learn from the poorly-conceived and abysmally presented papers produced by UIDAI, all way below the standard demanded of respectable academic authorities. They inspire no confidence.
Your “Critics Argument” couldn’t be more wrong. If you are interested in investing in BAT shares, you don’t do so just because a BAT director tells you how marvellous the company is. You check the audited report and accounts first. That’s not to say that the BAT director is a liar. It’s just dutiful prudence.
Aadhaar is an investment. A big one, around Rs. 72,000 crore according to
Your money, Ram, is being invested in the project. Are you happy that that investment of your money is prudent? Do you think Aadhaar will curtail corruption? Or automate corruption?
Do you seriously think the banks will accept nothing but Aadhaar biometrics to authenticate payments? That’s the acid test. Maybe they will, but the history of uninterrupted failure of mass consumer biometrics is against it happening.
I choose BAT as an example because, back in 1980, I did some work at BAT (UK & Export) Ltd, here in the UK. They were converting their computer systems from Burroughs Medium Systems to something else and they used an Indian company to re-write the software. Their IT director told me he was staggered. Not only did the Indians do the conversion job, but they corrected all the errors in the system that BAT knew about and many they didn’t and they supplied an unparalleled set of test data.
That has coloured my view of India ever since and you’re wrong if you think I am trying in any way to denigrate Indian abilities.
For that, for a slab of high-handed Indian denigration, de haut en bas, we know best, take a look at The Economist magazine here and here
Or take a look at Morpho. You think, and I think, that Aadhaar is an Indian achievement. Morpho don’t. They think it’s a French achievement: “Morpho is in charge of all technological aspects of Aadhaar”, they say, Maybe someone should tell Mr Nilekani he needn’t come into the office, he’s not needed, not now Morpho are here.

Welcome to the Planet Biometrics e-newsletter

Dear Colleagues

Welcome to our next Planet Biometrics e-newsletter.

This week the Indian UIDAI released an incredibly positive report into the performance of biometrics at an unprecedented scale. Bearing in mind the number of naysayers that have continually doubted the performance of biometric technology and who predicted that India would "drown in a sea of false positives" [1], our industry should be waving thi9s report from the treetops.
Next week we will be running a full-length feature article on the findings of the report and the workings of the project.
Why not forward this newsletter on to a colleague so that they can also subscribe by clicking here [2]
Best regards
Mark Lockie


It's just a guess, but I bet that there will be no full-length feature article on the findings of the report and the workings of the project next week, or any other week. Mr Lockie's masters must be furious at and frightened by UIDAI's ill-considered report.
UIDAI faced an existential threat. They had to do something, to survive. So they produced this report, 'Role of Biometric Technology in Aadhaar Enrollment' [3], to demonstrate that their biometrics are reliable and that there is therefore a point to their existence.
Unfortunately, UIDAI have over-egged the pudding. And gilded the lily. Their ploy will be written up in the business school manuals for years to come in the how-not-to-do-it section, what-seemed-like-a-good-idea-at-the-time-blows-up-in-your-face category.
Look at it from the biometrics suppliers' point of view. UIDAI have claimed astonishing reliability for their biometrics, a reliability that has never been seen before and which no respectable expert has ever predicted before – "incredible" and "unprecedented", as Mark says. What are Morpho [4], for example, supposed to say now, when potential customers approach them saying that they, too, want a biometric failure to enrol rate of 0.14 percent and a false positive identification rate of 0.057 percent and a false negative identification rate of 0.035 percent?
Morpho and the others have eschewed the publication of performance figures for years. They look like warranties. And why give warranties if you don't have to?
Existing customers with worse performance figures will want to know why they haven't achieved the same reliability as UIDAI claim to have done. Again, what do Morpho say to them? "We sold you a defective product compared with UIDAI's"? Or maybe "UIDAI just made the numbers up, it's all politics, don't worry their performance is actually just as bad as yours"?
Morpho [5] must wish UIDAI hadn't published that report.
What are the banks going to say? "UIDAI's performance is so good, apparently, that we ought to be using the same technology to authenticate payments all over the world, not just in India. Still, better check first, can we see the independent audit of UIDAI's figures, please? Purely a formality but, you know, have to tick all the boxes ..."?
No, the attempt will be made to bury that UIDAI report as quickly and as thoroughly as possible (save your copy now [3]). And Mark Lockie will be asked/told to keep quiet. "No full-length feature articles please, Mark, as you always say, you're 'not technical', just forget it. Now. That's an order."

1. Possibly a reference to David Moss, naysayer and author of 'India's ID card scheme – drowning in a sea of false positives',
5. "Morpho is in charge of all technological aspects of Aadhaar ...",

Seems like Moss has fun talking to himself...
Every one of his articles on UIDAI has now been discredited, and yet he asks some of the most eminent professors guiding the UIDAI project (Daugman/Wayman) to reply. Not likely!
As for drowning in a sea of false positives, even a fool could see that Prof. Daugman made his comments warning that this could happen without iris. Our Indian project uses iris...
Moss should grow a backbone and admit he is wrong. Even in the face of facts he blindly refuses to accept that this multi-modal, multi-supplier project is delivering impressive results. Moss is happy to quote reports inaccurately when he feels like it. But disregards them as rubbish when they contradict his anti-biometric bile.
Mr Moss, you are, Sir, a Luddite in the extreme. Feel free to talk to yourself some more...

In the charmed world inhabited by Observer, UIDAI's biometrics are reliable because UIDAI say they are.

Not good enough. This is politics. Samir Kelekar clearly understands that. So does Indian. So does Mathew. Why doesn't Observer?

Because he isn't observant. Observer misses the promise already made, in the response to Dingy, willingly to apologise if and when there is a reason to do so.

In the meantime, the Prime Minister has given UIDAI and NPR equal shares of the Indian population, 60 crore each. Is the technology used by the two organisations equal? We don't know.

Instead of making a technology decision, a political decision has been made, a decision UIDAI have lobbied for worldwide, not least through The Economist magazine, whom UIDAI seem to have successfully suborned,

Next comes the financial decision. Will Parliament vote the money needed for Aadhaar's next phase? Perhaps the money men will be more observant. This is public money after all, and public money should not be wasted.

Even in the face of facts? Since when did UIDAI's sales spin become facts? It would be good if UIDAI can get some acknowledged expert do an independent audit and let us know the truth.


In Reply to Observer 5 years ago

Only time will tell, who is wrong, the UIDAI, Moss or Observer. But in all the process, we Indians are going to be tagged with free access to anyone to our biometrics. Why they are not using biometrics in the US and in the UK for their own residents, may I ask? Why single out only Indians? Any observation for obvious reason....

NPR uses biometrics.
NREGA uses biometrics.
UIDAI uses biometrics.
UIDAI claims to have achieved a biometric failure to enrol rate (B-FTE) of 0.14 percent and a false positive identification rate (FPIR) of 0.057 percent and a false negative identification rate (FNIR) of 0.035 percent.
What are the equivalent figures for NPR and NREGA?

David Moss

Lovely to hear from you.
UIDAI faced an existential threat. They had to do something, to survive.
They elected to produce a report claiming that their use of biometrics in Aadhaar is reliable.
They may have slightly over-egged the pudding or gilded the lily – rather than mere reliability, their report claims near-perfection.
Not only has a biometric failure to enrol rate of 0.14%, a false positive identification rate of 0.057% and a false negative identification rate of 0.035% never been simultaneously claimed before, but no respectable expert has ever suggested that it is achievable.
One must therefore look at these figures with some circumspection.
The biometrics suppliers such as Morpho must be having kittens. They don't like performance figures being published – they look like warranties, and that's the last thing they want to give.
The banks must be scratching their heads. If this sort of reliability is achievable, how come they aren't authenticating payments with biometrics all over the world?
By all accounts, UIDAI's ploy has worked and the Prime Minister has given the go-ahead for a further 400 million enrolments. Well done, UIDAI.
But now there's a price to pay. More and more people are going to want to see those figures audited.
Because if they are correct, Dingy, not only will I apologise but the world will change, this will be a revolution.
Conversely, if they turn out to be a cynical trick to stay in business, UIDAI are going to have to run fast, ahead of 1.2 billion Indians who want their money back and there may not be time for them to apologise first.
What do you think, Dingy? Which way will it go?

Best wishes

Another article in david moss's truthless campaign on biometrics. Some time back the same guy written articles that UID can not even be generated for 1 crore people and had also predicted that UIDAI will drown in sea of false positives.

But UIDAI has proved that, all that talk was non sense and they have successfully created 12 crore numbers. Mr Moss has to apologize for his past arrogance.



In Reply to Dingy Moss 5 years ago

Have the adherents of UID forgotten the frauds that the enrollers have been committing? For example, a number of people were enrolled with references provided by a fake doctor, a MLA's and a MP's offices. This is the 'Headlines Today' expose. No one knows how many such enrolments have been done. Could many of these be foreigners, criminals, etc? How would these people be identifies, if they are illegal immigrants or Headley's collaborators? There seems to be an urge to increase enrolments. Why? Is this a Guinness record to be beaten? UIDAI technologists seem to have forgotten GIGO! It is not enrolment, but accuracy of the data for the purpose for which the enrolment is done that is important. If it to save subsidies, then one must find out if the enrolled person is eligible or not. If it is for citizenship, then one must find whether the person is a citizen or not. No amount of biometric accuracy would help in any of these.

What does it take to generate 12 crore ids ? A database and some printer paper. Are you swallowing the spin doled by UIDAI that it is % accurate ? You seem to be totally ignorant of the realities of this world. Never trust a sales man's sales talk. Check out things for yourself.

Indeed, UIDAI is also silent about how easily fingerprints can be faked. A criminal waste of money aka 2G scam. MMS doesnt seem to learn anything from past mistakes.

UIDAI patting its own back, and MMS listening to it extending UIDAI's mandate?

Indeed, the pathetic level of this govt. couldnt have been better revealed than this.

It is such decisions without any thinking that allow people such as Kasab to come and do what they want in this country. And who is going to pay for this collosal waste of public money? It is time to show the door to the Congress in this election in the states. I am out campaigning against Congress in my home state Goa.


Food inflation at (-)1.03%; in negative zone for fourth consecutive week

Attributing the decline in food inflation mainly to seasonal factors, the central bank said the impact of good vegetable output will remain limited in the absence of effective measures to address supply-side bottlenecks

New Delhi: India’s food inflation remained in the negative zone for the fourth week in a row, at (-)1.03% for the week ended 14th January, on account of cheaper vegetables, reports PTI.

Food inflation, as measured by the Wholesale Price Index (WPI), was at (-)0.42 per cent in the previous week. It was above 17% in the corresponding week of 2011.

According to the official data released on Friday, onion prices fell steeply by 79.10%, year-on-year, for the week under review, while potato prices were down 22.46%. Prices of wheat also fell by 3.37%.

Overall, vegetables were 47.06% cheaper during the week under review, from the same period last year.

However, other food products, led by protein-based items, became more expensive on an annual basis.

Pulses prices were 12.77% higher, while milk grew dearer by 12.25%. Eggs, meat and fish prices were up 20.33% year-on-year.

Fruits also became 5.17% more expensive on an annual basis, while cereal prices were up 2.71%.

Inflation in the overall primary articles category stood at 1.89% for the week ended 14th January, as against 2.47% in the previous week. Primary articles have a weightage of over 20% in the wholesale price index.

Experts feel that the decline in food inflation, along with moderation in headline or overall inflation in December will be a major incentive for the Reserve Bank of India (RBI) to look at the option of cutting key interest rates in the near future.

At its third quarterly monetary policy review earlier this week, the apex bank had injected Rs32,000 crore into the system by lowering the Cash Reserve Ratio (CRR) by half-a- percentage point to 5.5% but kept the short-term lending rate unchanged.

Inflation in the non-food primary articles segment, which includes fibres and oilseeds, was recorded at 0.56% for the week ended 14th January against 1.84% in the previous week.

Fuel and power inflation stood at 14.45%, same as in the previous week.

Headline inflation, which also factors in manufactured items, fell to a two-month low of 7.47% in December.

According to experts, the moderation in both overall inflation and food inflation will allow the RBI to look at the option of reversing its tight monetary policy in near future.

In its review, RBI had however said inflation remains a concern in view of volatile crude prices in international markets and widening fiscal deficit.

Attributing the decline in food inflation mainly to seasonal factors, the central bank said the impact of good vegetable output will remain limited in the absence of effective measures to address supply-side bottlenecks.

RBI had hiked interest rates 13 times between March 2010 and October 2011 to curb demand and tame inflation.

The apex bank, which has pegged the year-end inflation at 7%, said the revision in domestic-administered prices would add to inflationary pressures.


Twitter ‘to selectively censor tweets’

In its blog post, titled ‘Tweets Must Flow’, the San Francisco-based micro-blogging company has said that it could “reactively withhold content from users in a specific country” if legally required to do so

Washington: Twitter has announced that it can now selectively censor tweets on a country-by-country basis, a move which may augur well for India which reportedly urged social media websites to remove offensive contents, reports PTI.

In its blog post, titled ‘Tweets Must Flow’, the San Francisco-based micro-blogging company has said that it could “reactively withhold content from users in a specific country” if legally required to do so.

The proposed move came amid reports of a legal clash between India and global Internet giants, including Google, Yahoo, Twitter and Facebook, over pre-screening user contents and removal of offensive materials from their websites.

A Delhi court had last month asked 21 social networking websites to remove derogatory content by 6th February this year.

In its blog, citing France or Germany which ban pro-Nazi content as examples, Twitter said: “As we continue to grow internationally, we will enter countries that have different ideas about the contours of freedom of expression.

“Starting today, we give ourselves the ability to reactively withhold content from users in a specific country—while keeping it available in the rest of the world.

“We haven’t yet used this ability, but if and when we are required to withhold a tweet in a specific country, we will attempt to let the user know, and we will clearly mark when the content has been withheld.”

However, the micro-blogging service with over 100 million active users, said the removed content would be available to the rest of the world. Earlier when it used to delete a tweet, it would disappear worldwide, media reports said.

Along with social media sites like Facebook, Twitter, which is currently banned in China, is said to have played a pivotal role in uprisings that swept the Middle East region, particularly in countries like Egypt and Tunisia.
