Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing database-centered computer network systems lack robust cryptographic security and efficient data management mechanisms for distributed environments, particularly in managing sensitive corporate data and ensuring secure access and policy compliance across multiple entities.
Innovation Solution
A network of externally owned presence (EOP) member nodes, each with personalized cryptographic private keys, a distributed database, and self-contained self-executing software containers (SESCs) that generate state hashes and perform data actions based on entity permissions and policy criteria checks, using cryptographic hash functions like SHA-256 and SHA3.

Engineering Contradiction Analysis
1Productivity
If a distributed database system is implemented for data management, then data accessibility and processing efficiency are improved, but data security and privacy protection deteriorate due to multiple access points and potential vulnerabilities
Solution Approach 1:
The system segments data access rights by creating distinct roles (supervisory EOP member node and peer EOP member nodes) with different permission levels. The supervisory node generates and manages cryptographic private keys for peer nodes, enabling fine-grained control over data access while maintaining distributed architecture benefits
Solution Approach 2:
Cryptographic hash functions (SHA-256, SHA3) serve as intermediaries between data and access control mechanisms. These hash functions verify data integrity and enable permissioned access without exposing raw data, thus maintaining security while allowing efficient distributed data management
2Reliability
If cryptographic key management is centralized for security, then data privacy protection is improved, but system complexity and trust requirements deteriorate
Solution Approach 1:
The key management function is segmented between supervisory EOP member nodes (which generate and issue keys) and peer EOP member nodes (which store and use keys locally). This segmentation maintains centralized security oversight while distributing operational complexity across the network
Solution Approach 2:
Peer EOP member nodes autonomously generate their own cryptographic private keys based on templates or instructions from supervisory nodes. Each peer node independently manages its own key pair, eliminating the need for complex centralized key storage while maintaining security through cryptographic best practices
3Reliability
If access control policies are enforced at the database level, then data security is improved, but system performance and query efficiency deteriorate due to additional verification overhead
Solution Approach 1:
Permission verification is performed preliminarily at the EOP member node level before data retrieval operations. Each node checks its own permission status and the status of other nodes involved in the operation, pre-validating access rights so that when data is accessed, the verification overhead is minimized
Solution Approach 2:
The system changes the parameter of verification timing from post-query to pre-query. By determining permissions beforehand based on cryptographic private keys and node attributes, the system reduces runtime verification overhead while maintaining robust access control

AI summary
In some embodiments, the present invention provides for an exemplary computer system which includes at least the following components: a network of externally owned presence (EOP) member nodes, including a supervisory EOP member node is configured to generate at least one personalized cryptographic private key for each peer EOP member node; a distributed database, storing a plurality of persistent data objects; and a plurality of self-contained self-executing software containers (SESCs); where each SESC includes an independently executable software code which is at least configured to: apply entropy to generate a state hash representative of a current state of a persistent data object, perform a data action with the persistent data object; and determine that a particular EOP member node has a permission to cause the SESC to perform the data action with the persistent data object based.
