Concerns with Aadhar

Although Aadhar is probably the most important document for a person in India, certain concerns have been raised by people regarding Aadhar.

Concerns about Feasibility: Scholars have raised questions that for this venture the government has spent close to USD 1.3 billion and it was shown as a not profit venture. Yet UIDAI’s work does not end after issuing Aadhar as there are numerous after sale services that need to be provided. Scholars are of the opinion that the expenditure behind maintaining this project may turn out to be more that the amount of black money it can recover.

Lack of Legislative Backing: Aadhar was initially introduced as voluntary but gradually it has been made mandatory. Public interest litigations have been filed against the government in the Supreme Court of India, raising concerns whether UIDAI has a legal allowance to collect citizens’ biometric data.

Data Sharing Concerns: There have been issues which were dragged till courtrooms where law enforcement bodies have asked UIDAI to help them by sharing biometric details of escaped convicts and other “under trial” possible criminals who could be convicted if the data obtained from UIDAI matched the data with the law enforcement bodies. The court allowed UIDAI to do so but UIDAI was not ready and asked the Supreme Court of India to intervene. The Supreme Court overruled the judgment of the earlier court and the data was not shared. However, the reason why it was being asked for in the first place was for the benefit of the society.

Security Concerns with Aadhar Card: Many eminent and respected politicians said that on local levels, to gain political advantage a local councilor can easily arrange a ration card, voter card or councilors letter for an illegal citizen and that would fail Aadhar’s primary motive. Aadhar was introduced primarily to catch illegal immigrants in the country but later many subsidy programs and benefits were added.

Need of IRIS in the project

1. Ensuring Uniqueness

In order to Ensure Uniqueness, the Biometrics Committee played a vital role in helping UIDAI to decide Biometrics should be used in the project. One of the main challenge faced by UIDAI was to ensure uniqueness of all the 1.2 billion people across the country.

To achieve this, UIDAI has to compulsory minimize the false acceptance rate (FAR) in its biometrics. To reduce FAR, Biometrics Committee decided to take Biometrics of the fingerprints as well as the face. By involving iris to finger and face biometrics, it would be beneficial for UIDAI to achieve high levels of Accuracy more than 95% and also would ensure a very low FAR.

In order to provide better accuracy, the Biometric Committee submitted the report to the UIDAI. Later on, UIDAI reviewed the report and decided to include iris into the UID.

2. Ensuring Inclusion

By including iris in the UIDAI project, UIDAI wants to involve a large number of population in the project. The two main challenges faced by UIDAI are as follows:

Ensuring the inclusion of Poor residents:

UIDAI faces a challenge in collecting the Biometrics from the poor as their occupation is difficult and their fingerprints are generally worn out and that’s why difficult to capture.

Ensuring the inclusion of Children:

While collecting de-duplicating the biometrics of children, it’s very difficult, as their biometrics change until the age of 16. In order to ensure Child’s Biometrics, his/her UIDAI is being linked with the parents.

Other Benefits of iris

1. Comfort: While taking iris of the Citizen will be intruding. You can view the iris taken at one of the UIDAI’s Centre. However, iris capture doesn’t involve physical contact with the citizen.

How Aadhar UIDAI works

2. Ease of use: A trained Executive can easily take the iris and fingerprint of the citizen. Using newer devices, the operator can easily take the iris with an auto-focus feature.

3. Reducing risks in Execution: UID Enrollment will be held on a wide scale and in diverse environments. However, the enrollment of processes and system is standardized.

4. Reducing Technology Risks: There are noteworthy risks involved in the UID project. However, this type of system is not yet implemented in any other project across the country.

5. De-duplication: At the time of implementing new changes in the Biometrics project, experts pointed that iris de-duplication is very easy as compared to fingerprint de-duplication. By
Making multi-modal duplication, an iris is kept as primary duplication, which can be done much faster as compared to fingerprint de-duplication.

6. Applications: UID is useful for various purposes such as making financial transactions and making small payments. It is also useful to enjoy various benefits provided by the Government.

3. IRIS Technology

There are lots of benefits of IRIS Technology. There is not much information about how the IRIS Technology works.

IRIS is basically the most protected region in the human’s eye, it mainly controls the diameter of pupils – the center region of the eye and also the amount of light entering the eye.

How Aadhar UIDAI works

How to capture an image using iris?

The process to take photograph using iris is similar as a regular photograph, however, it operates in the infrared region, nearly visible to the eye. In this process, the device captures the image and then it is permanently stored in the database. It is very much useful at the time of de-duplication and Verification.

Devices used for iris capture

There are basically two devices that can be used for iris capture:
1. Wall mounted
2. Handheld

1. Wall Mounted: These devices are used to access control applications.
2. Handheld: E-Governance applications and for iris enrollment.


  •  The implementation of this new project in the market is useful and tends to bring various questions and answers. These questions arise because Technology is not known to the majority of people.
  •  The main reason to include Biometrics is to keep in mind the critical needs of the project in allocating the uniqueness of the number and also all the residents can also enroll in the UID easily.
