Can Blockchain Improve Healthcare Data Security in India?

 

The blockchain technology presents a revolutionary way of ensuring safety of the health data in India, countering the vulnerability of the centralized systems in the face of the increased cyber threats. It uses decentralization and cryptography to enable patients and providers to have tamper-proof records.

Blockchain's Core Security Features

Blockchain provides security to health data with distributed ledgers, that is, the data is stored in many nodes, not just one computer. This decentralization will eliminate the single points of failure, as was the case in the past attacks such as the 2022 AIIMS Delhi ransomware attack. Cryptographic hashing like the SHA-256 keeps data integrity but if there is an alteration in the data, another hash is generated and this automatically indicates tampering.

The access controls are automated through smart contracts and only verified providers can be granted access through predetermined rules. Patients become sovereigns regarding their electronic health records (EHRs), having a choice of who will read or share data on a pseudonymous basis. The model is privacy-enhancing and does not undermine usability.

Applicability to the Healthcare Landscape of India

The Ayushman Bharat Digital Mission (ABDM) of India was introduced in 2021 and is expected to make the EHR nationwide, but struggles with interoperability and privacy concerns. Blockchain fits perfectly as a bottom layer which would allow sharing data between hospitals, insurers and regulators in a secure manner. It addresses incomplete records of the chronic challenges in both the public and the private facilities.

In a country that has more than 1.4 billion inhabitants and the rural accessibility is behind, blockchain aids telemedicine and IoMT gadgets to monitor in real-time. When combined with AI, it allows making predictions and at the same time ensures that the changing laws of data are avoided. Programs such as blockchain investigations at IIT Bombay are indicative of increasing energy.

TCS Leadership Information

According to TCS Vice President Chakravarthy insights, scalable digital health solutions are the key focus, with cybersecurity tendencies emphasized in 2026. His vision as a former Global RMG Head in TCS incorporates blockchain-style protection of hospital data flows, where sensitive transmissions are encrypted by lattices. The TCS leadership of Bangalore led by ES Chakravarthy promoted the change in the workforce combining technology with care delivery.

The profile of Dr. ES Chakravarthy global head highlights the importance of having hybrid access models in order to serve the diverse needs of healthcare in India. His contribution with TCS Bangalore as a Vice President involved privacy in online platforms, which affected ABDM-like implementations.

Key Benefits and Implementation Steps

Blockchain decreases fraudulent claims handling through unalterable audit paths and drug supply chains. It reduces administrative expenses through workflow automation, which is used to release funds to care of patients.

To adopt it:

• Pilot hybrid models: Scale up to public-private blockchains.

• Establish governance: Unify protocols that are in line with DPDP Act 2023.

• Train stakeholders: Upskill through TCS management ES Chakravarthy platforms.

• Collaborate effectively: Force ABDM technology giants to be interoperable.

Issues such as scalability and regulation still exist, but gradual pilots such as incremental adoption echoed by Dr. ES Chakravarthy TCS news provide a way out.

Future Outlook

According to the new trends, 90% of medical data is set to be safeguarded by the blockchain by 2026 against breaches. Recent developments by ES Chakravarthy speculate on AI-blockchain synergies to resilient hospitals. TCS legacy positions India as the leader of secure digital health, where trust and equity are encouraged by ES Chakravarthy, global RMG leader.
