Identity Project

How efficient is Aadhaar? There's no way to know since the government won't tell

The UIDAI has received 331 crore authentication requests since 2012 but declined to reveal how many of them failed.

From the inception of the unique identity project, the government has claimed that one of the biggest advantages of Aadhaar – a biometrics-based 12-digit identity number for Indian residents – is that it helps identify beneficiaries of social schemes accurately and ensures the benefits go only to the deserving.

In March, the government notified that Aadhaar, or at least proof of enrolment in Aadhaar, was mandatory for several vulnerable groups to continue to receive government benefits. These groups included women rescued from trafficking, workers engaged in forced labour, schoolchildren between six and 14 years of age, and people with disabilities. Schoolchildren, for instance, will not be served mid-day meals from June if they cannot present their Aadhaar numbers.

All recent notifications state that the use of Aadhaar as a document of identification will bring in “transparency and efficiency”.

But is Aadhaar really making it easier for people to access welfare programmes? How accurate are the claims of greater efficiency? There are no answers to these questions, it seems, as Scroll.in’s requests for information under the Right to Information Act revealed.

Aadhaar authentication

An Aadhaar number is generated after the collection of demographic information and biometrics (fingerprints and iris scans). The number can be used by either the government or a private entity to authenticate a person carrying out a transaction that requires them to establish their identity. The database now has over a billion people enrolled in it.

One way of biometric authentication is through fingerprints. For example, several states such as Delhi, Rajasthan and Andhra Pradesh have made Aadhaar biometric authentication mandatory for those who wish to avail of foodgrains under the public distribution system. These beneficiaries must, therefore, place their fingers on the point-of-sale devices at fair price shops. The devices use the internet to verify the fingerprints with the data stored in the Aadhaar servers.

Besides fingerprint authentication, the Unique Identification Authority of India – the agency that manages the database – lists five other authentication techniques:

  • Matching the Aadhaar number and demographic attributes of residents.
  • Through a one-time password sent to the resident’s mobile number/email shared in the central identities database.
  • Using one of the biometric modalities – fingerprints or iris.
  • A two-factor authentication using one of the biometrics (iris, fingerprints), and a one-time password.
  • Using a one-time password, fingerprints and iris for authentication.

Lack of transparency

To monitor the efficacy of Aadhaar, the Authority is supposed to regularly collect this authentication data along with information on how many authentication requests were received, and how many failed or succeeded.

After the Aadhaar (Targeted Delivery of Financial and Other Subsidies, Benefits, and Services) Act was passed last year, Business Standard asked the Authority’s chief executive officer, ABP Pandey, in the course of an interview on March 22, 2016, about the system’s efficacy:

“Is there a system already in place for monitoring the efficacy of Aadhaar? Say, if I came to you six months down the line and asked how is the biometric system working? Would you be able to provide that authentication worked in 85% of cases or not? Are you regularly collecting this kind of data?

We monitor this. Say in one day, say, we get 2 million requests. Out of that we naturally have the information that so many have failed or so many has passed. The failure could be because of various reasons. Someone could have tried to falsify an identity, it could be a finger print failure. We also try to monitor the failure rate.”

Pandey also stated in the interview that “in some places where biometric is being used, like in Rajasthan for public distribution system, the rate of failure of fingerprint authentication is much higher than expected”. He added that it was not clear how much of the data on authentication failure would be put in the public domain, and what independent audit process would be adopted to monitor if the authentication was going on efficiently.

After the Aadhaar regulations were notified in September, this reporter submitted several right-to-information applications to the Authority seeking data related to authentication requests – as part of Scroll.in’s ongoing Identity Project series on the implementation of Aadhaar. The period for which information was sought was from September 2010, when the first Aadhaar number was issued, till October 31, 2016. Most of the replies from the Authority’s regional offices were received in December and January, with a final response coming in on March 1.

Replying to Scroll.in’s query, the Authority stated that it maintains month-wise data on how many authentication requests were received since September 2012. It does not maintain this data state-wise.

The Authority shared the total number of authentication requests received between September 2012 and October 2016 through five modes – fingerprint, iris, demographic, one-time password, and “other” – which came to a total of over 331 crore requests.

But it declined to share how many of these requests had failed or succeeded. To a question on how many times the Authority had returned a negative reply to the authentication requests, with a number for each of the five authentication modes, it stated that this data “is not readily available”.

No accountability

Government data and interviews with scheme beneficiaries show that individuals in some states, such as Rajasthan, have faced glitches and fingerprint authentication errors on a massive scale since Aadhaar was made mandatory to access food rations in 2015-’16. Thousands of households could not access their legal food entitlements and pensions because of this.

The beneficiaries are being denied for various reasons: if they do not have an Aadhaar number, if there are data entry errors in the details linked to or seeded in the public distribution database, if the fingerprint authentication does not work for many who do manual work or for the elderly. Also, electricity and internet connectivity problems, especially in remote villages, often mean that beneficiaries have to make multiple trips to the fair price shops, which in turn means losing a day’s wage for many of them.

Play

One of the first blueprints to be published for Aadhaar in welfare delivery was on the public distribution system.

“The Aadhaar number would be a foundation, over which the government can build more effective public distribution system processes,” the Unique Identification Authority of India stated in a 2010 policy document.

The paper envisioned that using Aadhaar would allow for “real-time identity verification at the fair price shop”, real-time streamlining for inventory management, and real-time tracking of beneficiaries’ claims by civil society activists.

In a sub-section titled “Community participation in monitoring” (page 11), the Authority stated:

“Aadhaar-based authentication and Management Information Systems would bring transparency to a currently opaque system. Clear accountability through Aadhaar authentication, as well as the use of electronic records, would make data more available for community monitoring, and would strengthen the use of right to information in the public distribution system.”

It added that an Aadhaar-enabled information technology grievance system “would ensure that complaints are visible publicly and across different levels of government”.

But that’s all on paper. Six years on, the process for tracking those who have been denied their legal entitlements, such as subsidised foodgrains under the National Food Security Act, and why remains as opaque as ever, say social activists.

“The biometric authentication technology claim is failing on a large scale in villages,” said Nikhil Dey, an activist with the Mazdoor Kisan Shakti Sangathan. “Yet, in three recent meetings, Rajasthan government has refused to share data with us on how many beneficiaries have been wrongly rejected, how many times, after how many authentication attempts.”

He added: “Why does the government want our information, while it keeps important public data such as these a secret?”

What’s the difference between ‘a’ washing machine and a ‘great’ washing machine?

The right machine can save water, power consumption, time, energy and your clothes from damage.

In 2010, Han Rosling, a Swedish statistician, convinced a room full of people that the washing machine was the greatest invention of the industrial revolution. In the TED talk delivered by him, he illuminates how the washing machine freed women from doing hours of labour intensive laundry, giving them the time to read books and eventually join the labour force. Rosling’s argument rings true even today as it is difficult to deny the significance of the washing machine in our everyday lives.

For many households, buying a washing machine is a sizable investment. Oddly, buyers underestimate the importance of the decision-making process while buying one and don’t research the purchase as much as they would for a television or refrigerator. Most buyers limit their buying criteria to type, size and price of the washing machine.

Visible technological advancements can be seen all around us, making it fair to expect a lot more from household appliances, especially washing machines. Here are a few features to expect and look out for before investing in a washing machine:

Cover your basics

Do you wash your towels every day? How frequently do you do your laundry? Are you okay with a bit of manual intervention during the wash cycle? These questions will help filter the basic type of washing machine you need. The semi-automatics require manual intervention to move clothes from the washing tub to the drying tub and are priced lower than a fully-automatic. A fully-automatic comes in two types: front load and top load. Front loading machines use less water by rotating the inner drum and using gravity to move the clothes through water.

Size matters

The size or the capacity of the machine is directly proportional to the consumption of electricity. The right machine capacity depends on the daily requirement of the household. For instance, for couples or individuals, a 6kg capacity would be adequate whereas a family of four might need an 8 kg or bigger capacity for their laundry needs. This is an important factor to consider since the wrong decision can consume an unnecessary amount of electricity.

Machine intelligence that helps save time

In situations when time works against you and your laundry, features of a well-designed washing machine can come to rescue. There are programmes for urgent laundry needs that provide clean laundry in a super quick 15 to 30 minutes’ cycle; a time delay feature that can assist you to start the laundry at a desired time etc. Many of these features dispel the notion that longer wash cycles mean cleaner clothes. In fact, some washing machines come with pre-activated wash cycles that offer shortest wash cycles across all programmes without compromising on cleanliness.

The green quotient

Despite the conveniences washing machines offer, many of them also consume a substantial amount of electricity and water. By paying close attention to performance features, it’s possible to find washing machines that use less water and energy. For example, there are machines which can adjust the levels of water used based on the size of the load. The reduced water usage, in turn, helps reduce the usage of electricity. Further, machines that promise a silent, no-vibration wash don’t just reduce noise – they are also more efficient as they are designed to work with less friction, thus reducing the energy consumed.

Customisable washing modes

Crushed dresses, out-of-shape shirts and shrunken sweaters are stuff of laundry nightmares. Most of us would rather take out the time to hand wash our expensive items of clothing rather than trusting the washing machine. To get the dirt out of clothes, washing machines use speed to first agitate the clothes and spin the water out of them, a process that takes a toll on the fabric. Fortunately, advanced machines come equipped with washing modes that control speed and water temperature depending on the fabric. While jeans and towels can endure a high-speed tumble and spin action, delicate fabrics like silk need a gentler wash at low speeds. Some machines also have a monsoon mode. This is an India specific mode that gives clothes a hot rinse and spin to reduce drying time during monsoons. A super clean mode will use hot water to clean the clothes deeply.

Washing machines have come a long way, from a wooden drum powered by motor to high-tech machines that come equipped with automatic washing modes. Bosch washing machines include all the above-mentioned features and provide damage free laundry in an energy efficient way. With 32 different washing modes, Bosch washing machines can create custom wash cycles for different types of laundry, be it lightly soiled linens, or stained woollens. The ActiveWater feature in Bosch washing machines senses the laundry load and optimises the usage of water and electricity. Its EcoSilentDrive motor draws energy from a permanent magnet, thereby saving energy and giving a silent wash. The fear of expensive clothes being wringed to shapelessness in a washing machine is a common one. The video below explains how Bosch’s unique VarioDrumTM technology achieves damage free laundry.
