Introduction

In the second episode of SecureDApp’s Bharat Security Initiative series, we sit down with Captain Prateek Bhamri — a cybersecurity evangelist and military veteran with over 15 years of experience. As the former Head of Cybersecurity and Blockchain at Spiro, Africa’s largest EV company, he sheds light on the future of data privacy and how blockchain can help India build a more secure digital ecosystem.

From Naval Service to Cybersecurity Leadership

Captain Bhamri’s journey demonstrates how national security expertise can align with corporate innovation.

He joined the Indian Navy in 2006 when the force began recruiting computer science graduates into its electrical branch. During his tenure, he worked on combat management systems, network integration, and joint tactical operations. While serving, he also completed his master’s at IIT Madras, which later supported his move to Vessi — a critical innovation unit within the Navy responsible for indigenization and advanced defense technologies.

At Vessi, he contributed to blockchain-based crypto systems, quantum technologies, and cloud infrastructure for defense. After completing his short-service tenure in July 2024, he transitioned to Spiro as Head of Cybersecurity and Blockchain. Today, he oversees security for one of Africa’s fastest-growing EV ecosystems, supported by the company’s tech hub in Pune, India.

Expertise Across Security Functions

Throughout his career, Captain Bhamri has led cross-functional teams across strategy, GRC, security operations, audits, and learning & development. His experience also spans prototyping, R&D, and engineering secure, high-assurance systems — making him a strong voice in India’s evolving digital security landscape.

Blockchain and India’s Data Privacy Challenges

When asked about blockchain’s role in solving India’s data privacy issues, Captain Bhamri emphasizes a crucial point: technology becomes impactful only when supported by strong regulatory frameworks. The Digital Personal Data Protection Act (DPDPA) provides this clarity and strengthens blockchain’s position as a tool for privacy, not just cryptocurrency.

The First Principle of Privacy: Data Minimization

According to Captain Bhamri, organizations often store unnecessary or duplicate data, resulting in shadow IT and unmanaged assets. He stresses that you can protect data only when you know what exists.
By minimizing redundant datasets, companies reduce risk and build the foundation for better control.

How Blockchain Enhances Data Transparency

Blockchain offers several capabilities that directly support privacy and accountability:

• Tracing data flow across systems
• Identifying data owners and custodians
• Increasing visibility into where data resides
• Detecting changes or unauthorized actions

Earlier, organizations struggled with scattered data lakes and unstructured storage patterns. Today, with AI systems absorbing vast amounts of information, the stakes are even higher. Blockchain brings order to this complexity by enabling structured, tamper-evident tracking.

Introducing Data Supply Chain Management

One of Captain Bhamri’s most notable insights is the idea of data supply chain management — an approach that tracks data throughout its entire lifecycle.

Data continuously changes form. It moves between custodians, processors, and platforms. Understanding this evolution is essential. For example, when someone asks an AI model like ChatGPT a question, the response draws from several layers of data. But can users trace where that data came from?
Blockchain finally makes this possible by recording immutable hashes at each step.

Consent Management in the DPDP Act

The DPDP Act grants data principals rights such as:

• Editing personal data
• Deleting data
• Modifying previously shared information
• Porting data to another provider

Captain Bhamri explains that consent mechanisms must be opt-in, not opt-out. In some regions, consent must even be refreshed every three months. Because of this, organizations must design simple, user-friendly consent systems that respect ownership rather than prioritize monetization.

Future: Blockchain-Based Consent Management

Looking ahead, Captain Bhamri believes that consent management will eventually move to blockchain.
In such a system, any action performed by a data processor or custodian becomes immediately visible to the individual. This transparency builds trust and creates a provable audit trail — a powerful advantage in India’s expanding digital ecosystem.

SecureDApp’s Approach

With the belief that 97% of blockchain hacks are preventable, SecureDApp continues to highlight the importance of proactive security. Through the Bharat Security Initiative, experts like Captain Bhamri share ground-level insights that help organizations strengthen privacy, compliance, and blockchain security.

Expert Q&A Highlights

1. On His Journey from the Navy to Spiro

Captain Bhamri speaks about joining the Navy as one of the first computer science graduates, learning electrical systems, and managing combat networks. After his master’s at IIT Madras, he worked at Vessi on blockchain, quantum, and cloud technologies. In 2024, he moved to Spiro, where he now secures vast data ecosystems across Africa.

2. On Blockchain’s Role in Data Privacy

He notes that blockchain becomes powerful when paired with regulations like DPDPA. Its ability to trace data, reduce redundancy, prevent shadow IT, and provide transparency makes it ideal for privacy-centric environments.

3. On Data Supply Chain Management

He explains how organizations must track where data originated, how it changed, and who interacted with it. Blockchain’s immutable hashes allow this level of visibility.

4. On Consent Management

He highlights the DPDP Act’s requirement for opt-in consent and stresses that consent systems must be easy, transparent, and user-first. Blockchain can make this process fully auditable.

Conclusion

Captain Prateek Bhamri’s insights underline how blockchain can fundamentally transform India’s data privacy landscape. With the DPDP Act accelerating compliance requirements, organizations now have a chance to adopt solutions that safeguard data, respect user rights, and ensure transparency.

As India continues to digitize rapidly, expertise that blends cybersecurity, defense strategy, and emerging technologies will be essential. This episode of SecureDApp’s Bharat Security Initiative reinforces how collaboration across industries can help build a stronger, more secure digital future.
