Market Context — Why This Technology, Why Now

Global regulatory bodies are increasingly enacting stringent data privacy laws, such as GDPR and CCPA, creating a complex compliance landscape for businesses. Simultaneously, the demand for transparent and immutable data records, often met by blockchain, clashes with individual data rights. This technology addresses this critical tension, offering a pathway for enterprises to build trust, avoid substantial penalties, and innovate with data while respecting user privacy in an evolving digital economy.

Key Competitive Advantages
01

Enables 'Right to be Forgotten' on Blockchain: Resolves the conflict between blockchain's immutability and GDPR's 'right to be forgotten' through a unique cryptographic key update approach.

02

Eliminates 'Proof of Absence' Challenge: Addresses the challenge not by proving the absence of a key (difficult in conventional blacklist methods), but by proving the existence of an alternative key.

03

High Uniqueness and Robust Patent Rights: Demonstrates strong technical superiority with only two prior art documents cited by the examiner. This robust patent was granted after overcoming multiple rejections.

ROI Calculation Logic

This technology could avoid significant GDPR violation fines, which can be up to 4% of annual revenue. For example, a company with ~$350M (AI est.) in annual revenue could reduce GDPR-related litigation risk and compliance costs by ~$350K/year (AI est.), representing ~0.1% of revenue risk. Additionally, it could reduce annual operational costs for legal and compliance departments by ~20%.

Speed to Market
6× faster than in-house development
This technology's algorithm has already been published as a technical report, establishing its fundamental specifications. This significantly shortens development time compared to enterprises building a similar system from scratch. Designed for integration into existing systems, it enables rapid utilization of proven technical elements, likely compressing time-to-market.

Y: Regulatory Compliance Assurance

Business Models & Applications
🔑 Software Licensing
A licensing model providing the core technology module as an SDK or API for enterprises to integrate into their own systems. Licensees can build GDPR-compliant blockchain systems while reducing development costs.
☁️ Data Sovereignty Management SaaS
A SaaS model offering this technology via the cloud. Enterprises can utilize blockchain-based data sovereignty management without complex infrastructure setup, significantly reducing operational burden.
⚖️ Compliance Solution
Provides an integrated compliance solution, with this technology at its core, addressing GDPR and national personal data protection laws. Deployable as a comprehensive service for legal and IT departments.
Adjacent Application Opportunities
🆔 Digital ID & Authentication
Application to Self-Sovereign Identity
This technology is applicable to managing personal data within Self-Sovereign Identity (SSI) systems. It could enable the construction of more trustworthy SSI platforms where users control access to personal information linked to their digital IDs and exercise the 'right to be forgotten', enhancing user data control by over 30%.
⛓️ Supply Chain Management
Reconciling Traceability with Data Deletion Rights
In blockchain-based supply chain management, this technology could ensure product history traceability while allowing the 'right to be forgotten' for specific personal data (e.g., delivery personnel information). This enables a balance between transparency and privacy protection, potentially reducing data privacy risks by ~25%.
🌐 Web3 & DAOs
Data Governance for Decentralized Autonomous Organizations
As personal information and activity logs are increasingly recorded on blockchains in Web3 and DAOs, this technology could enable data sovereignty management in decentralized environments. It offers a new governance model where participants regain control over their data, potentially increasing user trust and participation by 20%.
Integration Roadmap — Estimated 18-Month Deployment
Phase 1: Technology Evaluation and Requirements Definition
Duration: 3 months
Evaluate the core module's integration potential with existing systems and define specific requirements for GDPR compliance and data sovereignty management.
Phase 2: Prototype Development and Validation
Duration: 6 months
Develop a prototype system incorporating this technology based on defined requirements, then validate its functionality, performance, security, and regulatory compliance in a limited environment.
Phase 3: Production Deployment and Operations Optimization
Duration: 9 months
Proceed with production system deployment based on insights from prototype validation, followed by continuous monitoring and optimization post-launch, establishing a robust risk management framework.
Technical Feasibility
As indicated by its title, 'Computer System and Personal Information Provision Method,' this technology is a software-based solution, making its integration into existing IT infrastructure and blockchain systems relatively straightforward. The patent claims and detailed description suggest a generic encryption and key management mechanism independent of specific hardware. This implies a high potential for integration as a module or through API extensions into existing systems. The absence of physical capital investment suggests low adoption barriers.
Success Scenario
Implementing this technology could enable enterprises to achieve highly reliable data management leveraging blockchain's immutability while fully complying with personal data protection laws like GDPR. This would allow for technically appropriate responses to customer requests for the 'right to be forgotten,' potentially enhancing brand value and reducing compliance risks. Furthermore, by easing regulatory constraints, it could foster new data utilization business models previously deemed impossible, establishing a competitive advantage in the market.
