Non-fungible Preference Token for Decentralized User Data Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems face challenges in securely and efficiently collecting and managing user preference information, leading to privacy concerns and inaccurate data usage, as service providers lack comprehensive user profiles, and users have limited control over their data.
Innovation Solution
The implementation of a non-fungible preference token recorded on a public trust ledger, allowing users to control their preference information and authorize service providers to update it, ensuring secure and decentralized data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service providers collect and store user preference information in centralized databases, then they can provide personalized services, but user privacy is compromised and data security risks increase
Solution Approach 1:
The patent segments user preference data into discrete preference tokens that can be independently stored and managed on a blockchain. Each token represents a specific preference attribute, allowing service providers to access only the specific preferences needed for personalization without exposing the user's complete profile, thus maintaining privacy while enabling personalized services.
Solution Approach 2:
The patent introduces a blockchain-based preference token system as an intermediary between users and service providers. The blockchain acts as a decentralized mediator that stores user preferences securely and allows service providers to query and use these preferences without directly accessing or controlling the underlying user data, thereby protecting user privacy while enabling personalized service delivery.
2Loss of information
If service providers purchase user data from third-party providers, then they can build comprehensive user profiles, but data accuracy decreases and costs increase
Solution Approach 1:
The patent enables users to self-manage their preference data through the blockchain system. Users can directly input, update, and control their own preference information, which is then stored immutably on the blockchain. Service providers access this self-declared preference data directly from the blockchain, eliminating the need for third-party data brokers and ensuring high data accuracy while reducing costs.
3Ease of operation
If users have limited control over their preference data, then service providers can easily access and use the data, but user autonomy and privacy are reduced
Solution Approach 1:
The patent implements dynamic control mechanisms where users can adjust their privacy settings and data sharing preferences at any time through the blockchain system. The preference tokens on the blockchain can be configured with different access permissions and validity periods, allowing users to dynamically control which service providers can access which preferences and for how long, balancing ease of access with user autonomy.
4Device complexity
If centralized databases are used to store user preferences, then data management is simplified, but security risks and single points of failure increase
Solution Approach 1:
The patent leverages the blockchain's multi-functional capabilities to simultaneously achieve secure storage, decentralized access control, immutable record-keeping, and automated preference management. The blockchain system serves multiple functions: it acts as a secure database, a permission management system, an audit trail, and a data verification mechanism, thereby maintaining simplicity while dramatically improving security and reliability.
Data Source
AI summary
An interaction message may be received as part of a digital interaction between the database system and a remote computing device. A public trust ledger identifier associated with the interaction message may be determined. A non-fungible preference token recorded in a public trust ledger within a wallet owned by the public trust ledger identifier may be identified. The non-fungible preference token may include one or more preference values identifying preference information for a user associated with the public trust ledger identifier. An updated preference value based at least in part on the digital interaction. An instruction to update the non-fungible preference token to include the updated preference value may be sent to the public trust ledger.
