Adjustable Content Survival Time in P2P Information Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content deletion systems in information terminals do not consider the survival time of contents at the transmission destination, leading to inefficient memory management and content propagation in peer-to-peer (P2P) networks.
Innovation Solution
Implementing an information terminal and P2P system where contents are allotted with adjustable survival time, allowing for dynamic setting and control of this time on both the transmission and reception sides, enabling tailored content distribution and management within the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If contents are automatically deleted based on survival time at the receiving terminal, then memory space is efficiently utilized, but the survival time at the transmission destination is not considered, leading to potential content loss or duplication issues
Solution Approach 1:
The patent implements feedback by having the receiving terminal send back information about its survival time setting to the transmission terminal. This allows the transmission terminal to adjust and control the survival time of contents based on actual reception conditions, resolving the contradiction between memory utilization and information control.
Solution Approach 2:
The patent makes the survival time dynamic by allowing it to be adjusted based on feedback from receiving terminals. Instead of a fixed survival time, the system dynamically modifies survival time parameters according to actual network conditions and terminal requirements, enabling both efficient memory use and proper content control.
2Device complexity
If fixed survival time is set for contents, then implementation is simple, but adaptability to different terminals and network conditions is poor
Solution Approach 1:
The patent transforms the fixed survival time into a dynamic parameter that can be adjusted based on feedback from different terminals. This allows the system to adapt to varying network conditions and terminal requirements while maintaining a relatively simple implementation through automated feedback-based adjustment.
Solution Approach 2:
The patent changes the survival time parameter dynamically based on feedback information from receiving terminals. By modifying this key parameter according to actual conditions, the system achieves high adaptability without significantly increasing overall system complexity.
3Productivity
If contents are transmitted without considering survival time at transmission destination, then transmission process is simple, but memory management efficiency and content distribution control are reduced
Solution Approach 1:
The patent uses feedback from receiving terminals about their survival time settings to improve content distribution efficiency. The transmission terminal adjusts its behavior based on this feedback, enabling better memory management and content control without requiring complex manual intervention.
Solution Approach 2:
The system implements self-service by having receiving terminals automatically provide feedback about their survival time requirements, and the transmission terminal automatically adjusts accordingly. This automated process improves distribution efficiency without significantly increasing operational complexity.

AI summary
Information terminal and information sharing method are provided which consider survival time of contents at a transmission destination and propagate the contents widely so as to be suitable for contents sharing. In the information terminal and information sharing method, contents allotted with survival time is received, the survival time allotted to the contents is changed, contents allotted with the changed survival time is transmitted to a different information terminal, and the contents is deleted after the changed survival time has expired.
