Scope of Patent JP2015063562
Overall Objective
The patent aims to establish a secure, privacy-preserving data collection framework that enables the aggregation of patient data from various sources without compromising individual confidentiality. It emphasizes the integration, anonymization, and analysis of data for healthcare analytics, leveraging encryption, anonymization algorithms, and possibly blockchain or distributed ledger technologies.
Core Technology
The invention appears to incorporate multiple technological components:
- Data anonymization techniques: Masking or obfuscating personally identifiable information (PII) before data is stored or analyzed.
- Secure data transmission and storage: Possibly employing encryption protocols and secure communication channels.
- Distributed data management: Allowing multiple stakeholders (e.g., hospitals, pharmacies, research institutions) to participate without transferring raw, identifiable data.
- Analytical modules: For deriving statistical insights from de-identified datasets.
Claims Overview
The claims focus on both the methodology and the system architecture for anonymized data collection and analysis. Their scope broadly encompasses:
- Claim 1 (Independent claim): A method for collecting healthcare data that involves anonymization processes applied prior to data aggregation, coupled with secure transmission to a centralized or distributed repository.
- Dependent claims: Additional features such as specific anonymization techniques, encryption methods, workflows for data verification, and architectures for managing multi-party access.
- System claims: Hardware or software systems configured to implement these methods, including modules for anonymization, encryption, and data analysis.
Key aspects include:
- The automatic anonymization of patient data during collection or transmission.
- Use of cryptographic techniques to ensure data confidentiality.
- Implementation of access control mechanisms to restrict data visibility.
- Compatibility with existing health information systems in Japan.
Scope of Claims
The patent's claims are constructed with a broad scope to cover various embodiments of anonymized data collection, including:
- Different anonymization algorithms (e.g., pseudonymization, data masking, differential privacy).
- Multiple transmission protocols compliant with Japanese privacy laws.
- Systems incorporating blockchain or other distributed ledger technologies for traceability and auditability.
However, the scope remains tightly linked to healthcare data and patient privacy protection, limiting its applicability outside this domain without substantial modification.
Patent Landscape in Japan for Anonymized Healthcare Data
Legal and Regulatory Context
Japan’s legal environment, notably the Act on the Protection of Personal Information (APPI), imposes strict regulations on personal data handling, especially sensitive health information. These laws incentivize innovations that enable data utilization while ensuring privacy, fostering a robust patent landscape for privacy-preserving healthcare data technologies.
Active Patent Holders
Key players in this landscape include:
- Abridge Inc. (US-based with Japanese filings): Focused on secure medical data aggregation.
- NEC Corporation: Developing blockchain and encryption solutions for healthcare.
- Fujitsu Limited: Innovating in anonymization algorithms and secure data sharing.
- Hitachi, Ltd.: Active in secure data infrastructure and privacy-preserving analytics.
- Toyota Tsusho Corporation: Exploring blockchain-based health data management.
These entities have filed patents related to data anonymization, secure data sharing systems, blockchain in healthcare, and differential privacy, indicating a competitive environment that emphasizes privacy, efficiency, and legal compliance.
Related Japanese Patent Applications
Similar patent applications cover:
- Blockchain privacy mechanisms for medical data sharing (e.g., JP2018222085).
- Differential privacy algorithms for health data analysis.
- Secure multi-party computation (SMPC) frameworks in healthcare.
