A practical guide to how India's DPDP Act applies to biometric data and what organisations should consider when collecting, processing, and securing it.
India's Digital Personal Data Protection Act, 2023 (DPDP Act) establishes a legal framework for how organisations collect, process, store, and protect digital personal data. For organisations using biometric systems for employee attendance, access control, customer authentication, KYC, or field banking, understanding how the Act applies to biometric data is increasingly important.
Biometric information is particularly important from a data-protection perspective because it is directly associated with an individual's identity and can be difficult to replace if compromised. Organisations therefore need to consider not only why they collect biometric data, but also how it is captured, processed, stored, secured, and eventually deleted.
This article provides a plain-language overview of the DPDP Act and its relevance to organisations handling biometric data. It is not legal advice, and organisations should obtain advice specific to their sector, processing activities, and regulatory obligations.
The Digital Personal Data Protection Act, 2023 establishes India's legal framework for the processing of digital personal data.
The Act sets out obligations for organisations that determine the purpose and means of processing personal data, referred to as Data Fiduciaries. It also provides rights to individuals whose personal data is processed, referred to as Data Principals.
The framework addresses areas including:
The Act was passed in 2023, with detailed implementation dependent on the rules and notifications issued under the framework. Organisations handling personal data should therefore monitor the implementation timeline and applicable rules rather than treating the Act as a one-time compliance exercise.
The DPDP Act regulates personal data, which broadly covers data about an identifiable individual. Biometric information associated with an identifiable person can therefore fall within the scope of personal data covered by the Act.
Unlike the European Union's GDPR, the DPDP Act does not create an equivalent statutory category called "special category data" specifically for biometrics.
That does not mean biometric data should be treated casually.
A fingerprint or other biometric identifier is directly linked to an individual's identity and cannot simply be changed in the way a password can be replaced. Organisations handling biometric information should therefore apply appropriate safeguards and consider the risks associated with its collection and processing.
The exact obligations applicable to a particular biometric deployment will depend on the organisation, the purpose of processing, the legal basis for processing, and any other laws or regulations that apply to the activity.
Under the DPDP framework, an organisation determining the purpose and means of processing personal data may be a Data Fiduciary.
The individual whose personal data is being processed is the Data Principal.
This distinction is important for organisations using biometric systems.
For example:
In each case, the organisation needs to understand its responsibilities for the personal data it processes and how those responsibilities interact with any sector-specific requirements.
Consent is an important part of the DPDP framework, although it is not the only possible basis for processing personal data.
Where consent is the applicable basis, the Act requires consent to be free, specific, informed, unconditional, and unambiguous, and it must involve a clear affirmative action.
For organisations collecting biometric data, this means people should understand what information is being collected and the purpose for which it is being processed.
For example, an organisation introducing biometric attendance should establish an appropriate process for communicating relevant information to employees and documenting the applicable basis for processing.
Similarly, an organisation collecting biometric information as part of a customer authentication process should ensure that its data-collection and consent processes comply with the legal and regulatory requirements applicable to that particular service.
The Act also provides for withdrawal of consent, although organisations may have legal or regulatory obligations that affect whether and when particular data can be deleted.
This is one area where organisations should avoid adopting a one-size-fits-all policy. The correct approach depends on the purpose of processing and the other regulations governing the organisation.
Two important principles for organisations handling biometric data are data minimisation and purpose limitation.
Organisations should avoid collecting personal data that is unnecessary for the stated purpose.
For a biometric attendance system, for example, the organisation should determine what information is actually required to authenticate employees and maintain attendance records rather than collecting additional information without a clear purpose.
Personal data should be processed for the purpose for which it was collected, subject to the permissions and legal bases that apply.
A biometric identifier collected for attendance should not automatically be repurposed for unrelated activities such as marketing or profiling.
Organisations should therefore document why biometric data is being collected, what systems use it, who has access to it, and whether any additional processing is required.
Data retention is another important consideration.
Organisations should establish how long biometric information needs to be retained and ensure that data is not kept indefinitely without a valid reason.
For example, an organisation using biometric attendance should have a defined approach for handling biometric records when an employee leaves the organisation.
However, deletion requirements can become more complicated where other laws or regulations require records to be retained for a specified period.
A financial institution, for example, may have separate regulatory or statutory record-keeping requirements that need to be considered alongside its obligations under the DPDP framework.
Organisations should therefore establish retention schedules that take into account both the DPDP framework and applicable sector-specific requirements.
Organisations handling personal data are expected to implement reasonable security safeguards appropriate to the data and processing involved.
For biometric systems, security needs to be considered throughout the data lifecycle, not only once information reaches a central server.
The security chain can include:
The biometric device itself is therefore an important part of the overall security architecture.
Where biometric information is captured, hardware with appropriate security capabilities can help reduce exposure at the point of collection. For applications requiring UIDAI-certified biometric devices, organisations should also verify that the hardware meets the certification requirements applicable to their deployment.
However, certified hardware is only one part of data protection. Secure software, access controls, encryption, network security, appropriate retention policies, and organisational procedures all contribute to the overall security of biometric information.
The DPDP Act establishes a penalty framework for certain types of non-compliance, including failures relating to reasonable security safeguards.
The Act provides for significant financial penalties, with some categories carrying penalties of up to ₹250 crore.
The potential financial consequences reinforce an important point for organisations handling biometric data: data protection should be treated as an operational and governance responsibility rather than simply an IT issue.
The precise obligations and enforcement position will depend on the applicable provisions, rules, notifications, and circumstances of a particular case.
Organisations do not need to wait until a compliance issue arises to understand their biometric data flows.
A practical starting point is to review the following areas.
Identify:
This provides the foundation for assessing your data-protection responsibilities.
Determine whether your organisation has an appropriate legal basis for processing biometric information and whether individuals receive the information required under the applicable framework.
Where consent is being relied upon, review how consent is obtained, recorded, and withdrawn.
Biometric security begins when the information is captured.
Review whether the devices being used provide appropriate security protections and whether biometric information is protected during capture and transmission.
For applications requiring certified hardware, verify the device's current certification status rather than relying on general product descriptions.
Establish how long biometric information is actually retained and whether your systems can enforce the organisation's retention policy.
Where other regulations require records to be retained, document how those requirements interact with your data-protection obligations.
The DPDP Act may interact with other regulatory frameworks depending on the application.
For example, organisations operating in banking, financial services, government, education, or identity authentication may have additional requirements from regulators or government authorities.
A legal or compliance review specific to the organisation's activities is therefore important before making changes to a biometric deployment..
Data protection is not solely a software or legal issue. The hardware used to capture biometric information is part of the overall security chain.
For organisations deploying biometric attendance, authentication, KYC, or field banking systems, hardware selection should therefore consider:
The right hardware cannot by itself make an organisation DPDP-compliant. However, appropriately certified and secure biometric hardware can form an important part of a broader data-protection framework.
Access Computech provides UIDAI L1-certified biometric devices for applications including attendance, authentication, banking, and other identity-verification workflows.
The DPDP Act represents a significant shift in how organisations in India approach personal data. For businesses collecting biometric information, the key issue is not simply whether they use a fingerprint scanner or another biometric technology. It is whether they understand the complete data lifecycle, from collection and authentication through to security, access, retention, and deletion.
Organisations that map their biometric data flows, review their processing practices, strengthen security controls, and understand their sector-specific obligations will be better prepared as India's data-protection framework develops.
