A method and system for managing a permissions data lake
By constructing a Verkle tree and combining it with hidden vector commitments and a global permission relationship graph, the problem of insufficient permission conflict detection capability in permission data management is solved, achieving efficient permission updates and enhanced security.

AI Technical Summary
Existing permission data management technologies lack high-dimensional, context-sensitive dynamic modeling, resulting in insufficient permission conflict detection capabilities, excessively high update costs for tree or graph structures, and difficulty in timely detection of potential conflicts or abnormal patterns in permission inheritance chains.
Construct a Verkle tree and initialize the processing, update nodes using hidden vector commitments and sparse summation vector commitments, generate aggregate proofs, construct a global permission relationship graph and extract context-sensitive subgraphs, calculate a single topological index for conflict detection, and generate a post-quantum digital signature.
It significantly reduces the overhead of updating the tree structure, avoids information leakage, improves the system's ability to perceive and respond to potential permission risks, and enhances the transparency and security of permission management.
