The first part  of this report talked about the background and the security concerns with Aadhaar, the unique ID database of India, the largest of its kind in the world.
As questions emerge around flawed security  measures being used to protect India's digital ID database, government authorities are defending the system — and even taking action against those who are revealing its flaws.
Developed by the Union government of India in 2009, the plan called for the creation a Unique Identification Authority of India (UIDAI ) that would issue Unique Identity numbers (UIDs) to all residents of India. Under this scheme, now known as Aadhaar (which means “foundation” or “base” in Hindi), the UID number ties together several pieces of a person's demographic and biometric information, including their photograph, ten fingerprints and an image of their iris. This information is all stored in a centralized database. According to the UIDAI , a UID is meant to be “robust enough to eliminate duplicate and fake identities, and can be verified and authenticated in an easy, cost-effective way.”
The scheme has so far enrolled 1.13 billion Indians  and residents of India, making it the largest biometric database in the world.
In a 2016 report entitled Digital Dividends , the World Bank included “digital identity” among the four so-called digital enablers for development. With strong identification systems , the report's authors argue, it is possible to “deliver vital services to people, govern effectively, eliminate duplicative or inefficient programs, make efficient use of limited resources, and produce statistics accurately.”
But thus far, India's Aadhaar system has not achieved these aims and has in some cases increased obstacles  for citizens seeking to take advantage of basic public services, such as food subsidies . The system also has not actually reached all Indians: A Right to Information (RTI)  application filed  by Ujjainee Sharma and Trishna Senapaty revealed that as of June 2015, 0.03 per cent of all Aadhaar numbers issued were to people without any pre-existing identification documents. The applicants suspect that the total number of residents of India who do not possess ID numbers is much higher.
Authorities take action against critics, researchers
Apart from challenges of outreach, data mismanagement and machine errors, recent events have proven that Aadhaar numbers can be easily disclosed, posted online and used for malicious purposes. On May 1, researchers at the Centre for Internet and Society in Bangalore reported  that an estimated 135 million Aadhaar numbers had been leaked online from four separate government databases.
While the government has warned that publishing UID data on portals can lead to three years  imprisonment, a rule that likely deters some from posting UID numbers online, those reporting security flaws have also faced consequences.
When Skoch Group chairperson Sameer Kocchar showed in a February 2017 video blog post how the UID can be hacked , the UIDAI responded by accusing  him of violating Section 37  of the Aadhaar Act .
Section 37 says,”Whoever, intentionally discloses, transmits, copies or otherwise disseminates any identity information collected in the course of enrollment or authentication to any person not authorized under this Act or regulations made thereunder or in contravention of any agreement or arrangement entered into pursuant to the provisions of this Act, shall be punishable with imprisonment for a term which may extend to three years or with a fine which may extend to ten thousand rupees or, in the case of a company, with a fine which may extend to one lakh rupees, or with both.”
In another incident, a case  was filed against a journalist who showed on television how it was possible to obtain two separate UID numbers. To further complicate the issue, one may never know if their data has been breached , as the UIDAI refuses to disclose this type of information through Right to Information requests.
On Twitter, multiple users have tagged the @ceo_uidai and @uidai on relevant tweets, raising alarms against potential misuse of biometrics and leaks of UID data. But the Twitter handles of some of those who voiced the criticism have been blocked by government accounts . In responding to a subsequent RTI application asking the UIDAI whether they have banned anyone from their Twitter accounts, officials claimed  otherwise.
A tool for surveillance?
Another concern of privacy and security experts is that UID can be used as a tool for mass surveillance by government or other actors.
Various government spokespersons maintain that UIDAI collects minimal information . While that is true, services based on UID collect more than minimal information. @kingslyj provides an example of two state government entities that do precisely that:

The tool may also be further developed to collect more information in the future. Revelations by legislative researcher Meghnad from a debate in the Lower House of the Parliament earlier in 2017 indicated that DNA data might one day be included:

Centre for Internet and Society Executive Director Sunil Abraham has openly described Aadhaar as a surveillance tool:
Repeat after me: Aadhaar is surveillance technology masquerading as secure authentication technology.

Multiple national experts on law, privacy and technology have raised  concern  about the program's fraud and surveillance implications. New Delhi lawyer Apar Gupta, who has argued multiple privacy-related cases before the Supreme Court, explained in an interview with BuzzFeed News :
If your data is compromised in any way, there is absolutely nowhere that you as a citizen can turn to. There are no judicial remedies built into the Aadhaar program in case of identity theft.
Some of the worst fears of Aadhaar's critics were confirmed when a private company tweeted out a picture of what they could do with UID. The tweet has been deleted, but the original image has continued to circulate online:

In one of seven open letters to the Parliamentary Standing Committee on Finance that was scrutinizing what was then known as the National Identification Authority of India Bill , the Centre for Internet and Society laid down the inherent problems and pitfalls of using biometrics  as an instrument of authentication, offering technical recommendations intended to help avoid exploitation of the system.
Billionaire Nandan Nilekani, who is UID's main architect and the co-founder of IT company Infosys, has acknowledged  that privacy regulation is an “afterthought” of innovation and that India needs strong privacy laws after claiming for years that the scheme had built-in privacy and security features. Upper House MP Rajeev Chandrasekhar did not fail to miss Nilekani's change of heart.

In the background of this ongoing debate, the Attorney General of India  has argued in court that ‘privacy is not a fundamental right’  and has even referred to it as a concern of the elite or the corrupt .
It is worrying to see the government not respond adequately to concerns raised by the citizens, and even to punish those who have shed light on Aadhaar's flaws. This combined with a broad-based denial of privacy as a fundamental right gives the impression that they do not have plans to stop or even address the problems with the system.
