Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing PDS technology faces challenges in preventing illegal use of API keys, as they are difficult to control and manage the number of access attempts, leading to unauthorized access and information theft.
Innovation Solution
A method and system that dynamically manage access keys through a PDS, using a hash function to authenticate data service servers based on access number information, time information, and authentication information, allowing for real-time updates and verification of access operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If API key authentication is used for PDS access, then authentication can be performed, but security is compromised because API keys cannot prevent illegal use when exposed and cannot control access frequency
Solution Approach 1:
The patent applies dynamics by transitioning from static API key authentication to dynamic access key authentication. The access key changes based on time information and access number information, making each authentication instance unique. This dynamic approach prevents replay attacks and unauthorized reuse of exposed keys, while maintaining authentication reliability through cryptographic verification.
Solution Approach 2:
The patent changes the parameters of authentication from fixed API keys to variable access keys that incorporate time information and access number information. By modifying these parameters dynamically, the system prevents illegal use when keys are exposed and enables control over access frequency, resolving the security vulnerability of traditional API key methods.
2Object-affected harmful factors
If access control restrictions are implemented, then security is improved, but system complexity increases due to dynamic key management
Solution Approach 1:
The patent segments the authentication system into distinct functional modules: key generation module, verification module, and access control module. By dividing the system into these independent components with clear responsibilities, the patent manages complexity while implementing robust access control. Each module handles specific tasks, making the overall system more maintainable and less complex than a monolithic approach.
3Productivity
If dynamic access control is implemented, then access frequency can be controlled, but processing time increases due to real-time verification
Solution Approach 1:
The patent applies preliminary action by pre-generating access keys with embedded time information and access number information before actual access requests. The PDS system pre-loads and caches verification data, so when authentication is needed, the verification process is already optimized and ready. This reduces real-time processing time while maintaining access frequency control capabilities.
Data Source
AI summary
The present invention provides a method and a system for providing personal information services through managing access key for controlling dynamic access to PDS. The method includes: receiving, by a PDS, a storage space generation request signal from a user terminal; by the PDS, storing authentication information of a data service server and access number information, generating a user storage space, and transmitting address information of the user storage space and access-related information to the user terminal; by the data service server, generating an access key based on the access-related information and its own authentication information and transmitting a service request signal to the PDS, wherein the service request signal includes the access key; and by the PDS, verifying validity of the access key and performing a service when the access key is valid; wherein the access-related information includes the access number information and time information.
