Information Distribution System Using Intermediary Data Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information distribution systems require secure communication paths between information processing servers and distribution servers to ensure valid data distribution to communication apparatuses, which hampers system proliferation and may lead to unintended data distribution.
Innovation Solution
An information distribution system where an information processing server generates basic data containing identification data and transmits it to a communication apparatus, which then forwards it to a distribution server, allowing the distribution server to generate and distribute service data only if the identification data matches, thus preventing unauthorized access without the need for direct communication between the processing and distribution servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secure communication paths are established between information processing servers and distribution servers to ensure data distribution validity, then data security and validity are improved, but system complexity and communication overhead increase
Solution Approach 1:
The patent introduces basic data as an intermediary carrier that contains both service data and identification data. The communication apparatus acts as a mediator that receives basic data from the information processing server, validates identification data, and forwards service data to the distribution server. This intermediary mechanism eliminates the need for direct secure communication paths between servers while maintaining data distribution validity.
Solution Approach 2:
The patent segments the data transmission process into distinct components: basic data containing service data and identification data are separated, with identification data used for validation purposes. This segmentation allows the distribution server to operate independently without requiring direct communication with the information processing server, reducing system complexity while maintaining reliability.
2Reliability
If direct communication between information processing servers and distribution servers is implemented to validate communication apparatus, then data security is improved, but system scalability and proliferation are hindered
Solution Approach 1:
The basic data structure serves as a universal intermediary that enables any communication apparatus to validate its identity and receive service data from any distribution server without requiring direct server-to-server communication. This intermediary approach enhances system scalability and allows for easier proliferation of the system across different servers and apparatuses.
Solution Approach 2:
The patent creates a universal basic data format that can be used across different information processing servers and distribution servers. The identification data mechanism provides universal validation capability, allowing the system to scale and proliferate without requiring server-specific communication protocols or direct connections.
3Reliability
If identification data validation is performed at the distribution server, then unauthorized data distribution is prevented, but processing time and system response delay increase
Solution Approach 1:
The patent performs identification data validation as a preliminary action before service data distribution. The communication apparatus validates its identification data against the basic data received from the information processing server before requesting service data from the distribution server. This preliminary validation ensures that only authorized apparatuses can access service data, preventing unauthorized access while minimizing processing time by performing validation early in the communication sequence.
Data Source
AI summary
There is provided a communication apparatus including an identification data generation portion to generate identification data, an identification data storage portion to store the identification data generated by the identification data generation portion, a basic data reception portion to receive basic data from an information processing server through a given communication path, the basic data containing prescribed first data specifying service data generated in the distribution server and containing data to be used in an IC chip capable of con tactless communication with a reader/writer, and prescribed identification data, and a data acquisition portion to acquire the service data generated based on the basic data in the distribution server from the distribution server if the prescribed identification data matches with the identification data stored in the identification data storage portion.
