What Is Data Minimisation Under DPDPA?

Explore the principle of data minimisation under the DPDP Act 2023, and learn how to implement it to enhance privacy compliance and protect personal data

In an age where data is often touted as the new oil, the principles of data protection have never been more critical. Among these principles, data minimisation stands out as a cornerstone, particularly under the Data Protection and Digital Privacy Act (DPDPA). But what exactly does data minimisation entail, and why is it so vital?

Data minimization is a key principle in privacy protection laws worldwide. It mandates businesses to only collect the data they truly need for processing, and nothing more.

This principle is often misunderstood, with many businesses fearing that minimizing data collection and retention equates to losing out on valuable insights or hampering operations. However, this practice is not just about limiting data; it’s about reducing risk.

Collecting and storing unnecessary data not only increases the risk of data exposure but also leads to non-compliance with India’s Privacy Law, failing to safeguard individual privacy

What is Data Minimisation?

Data minimisation means processing only the minimal personal data necessary for your processing purposes. The goal is to adhere to privacy laws and reduce risks like data breaches, and unauthorised access.

Say, you run an online retail store and want to improve customer service by collecting feedback on recent purchases. To do this, you only need customers’ email addresses and details of their recent orders. By limiting your data collection to these elements, you are applying the data minimisation principle effectively.

However, if you decide to collect additional information such as customers’ home addresses or phone numbers solely for the purpose of gathering purchase feedback, you’ve gone beyond what is necessary. This extra information is not required to understand their satisfaction with their recent purchases.

To strictly practise data minimisation, here are some core principles that you need to follow:

Collect the Least Amount of Personal Data Required

The key to data minimization is to gather only the information needed to meet your goals. Businesses should regularly review their data collection methods to make sure they’re not asking for unnecessary details.

Here’s how to do it:

Limited Data Retention Periods

Keeping personal data forever is a bad practice. Companies should set clear data retention periods and ensure that once that time is up, the data is either anonymized or securely deleted.

Periodic Audits

Regular audits of data storage and usage can help identify and remove outdated or unnecessary personal data. This ensures that data minimization is an ongoing process, not a one-time effort.

How does Data Minimisation Help?

Before data protection and privacy laws became widespread, marketers and entrepreneurs believed that collecting as much data as possible was beneficial, just in case it might be useful later. However, this is not true.

Adopting a data minimization strategy and limiting data collection has several benefits for businesses.

Data Minimization under the DPDPA

The DPDPA stresses the importance of getting clear, informed consent before collecting personal data. This means clearly explaining what data will be collected, why it’s needed, and how it will be used. The goal is to collect only the minimum amount of data necessary for processing.

The DPDPA also requires Data Protection Impact Assessments (DPIAs) for risky high-risk data processing activities. These assessments evaluate how personal data is processed and whether this processing is necessary and proportional. They can also help identify and remove unnecessary and outdated personal data.

Best Practices by Industry

Healthcare

Minimum Necessary Rule: HIPAA mandates healthcare providers to ensure they only use, share, and request the minimal amount of information needed for a specific purpose.

Finance

E-commerce

Step-by-Step Information Collection: Information is gathered in stages and only when necessary, such as requesting shipping details only at the time of purchase.

A strategy that focuses on using as little data as necessary, supported by a company-wide emphasis on privacy and top-notch data practices, can greatly reduce data risks and increase consumer trust.
