The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The proposed invention, titled "Hybrid Blockchain Architecture for Privacy-Preserving Storage and Retrieval of Sensitive Records," introduces a secure, scalable, and efficient framework designed to protect sensitive data while ensuring controlled accessibility and integrity in distributed environments. In the era of digital transformation, organizations across sectors such as healthcare, finance, governance, and education generate and manage vast amounts of confidential information, making data privacy, security, and trust critical challenges. Traditional centralized storage systems are vulnerable to data breaches, unauthorized access, single points of failure, and lack of transparency, whereas fully public blockchain systems, although secure, may not be suitable for storing sensitive data due to issues related to data exposure, scalability limitations, and high computational costs. To address these challenges, the proposed system employs a hybrid blockchain architecture that combines the strengths of both public and private blockchains to achieve an optimal balance between transparency, security, and performance. In this architecture, sensitive data is stored off-chain in encrypted form within secure distributed storage systems, while only essential metadata, cryptographic hashes, and access control policies are recorded on the blockchain to ensure data integrity and immutability. The private blockchain component is utilized to manage access permissions, authenticate users, and enforce organizational policies, ensuring that only authorized entities can retrieve or modify records. Meanwhile, the public blockchain layer provides an additional level of transparency and auditability by maintaining tamper-proof logs of transactions and data access events. The system incorporates advanced cryptographic techniques such as asymmetric encryption, zero-knowledge proofs, and secure multi-party computation to enable privacy-preserving data sharing without exposing the underlying information. A smart contract-based access control mechanism is implemented to automate authorization processes, enforce compliance rules, and provide traceability of data interactions. Additionally, the architecture includes an intelligent retrieval module that allows users to securely query and access relevant records using authenticated credentials, while maintaining anonymity and minimizing data leakage. The system is designed with scalability in mind, leveraging modular components and efficient consensus mechanisms to handle large volumes of transactions and users. Furthermore, it integrates seamlessly with existing enterprise systems and cloud infrastructure, enabling easy adoption without significant disruption. A user-friendly interface and monitoring dashboard are also incorporated to provide real-time insights into data access activities, system performance, and security status. By combining blockchain technology with advanced cryptographic and distributed storage techniques, the proposed invention ensures enhanced data confidentiality, integrity, and availability, making it highly suitable for applications requiring secure handling of sensitive records. Overall, this hybrid blockchain architecture represents a significant advancement in privacy-preserving data management, offering a reliable and future-ready solution for secure storage and controlled retrieval in modern digital ecosystems."
