Adaptive Message Lifetime Management in Packet Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing instant messaging systems lack the ability to adaptively manage and secure message lifetimes based on recipient attributes and security clearances, leading to uniform treatment of all recipients, which is inadequate for contexts requiring differential security and risk management.
Innovation Solution
A method where data message attributes, including type, encryption keys, and recipient device attributes, determine the lifetime of message contents, allowing for synchronized display durations and storage strategies that cater to individual recipients' security clearances and locations, ensuring secure and adaptive message management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If uniform message lifetime is applied to all recipients, then system complexity is reduced, but security and adaptability are compromised
Solution Approach 1:
The patent applies local quality by assigning different message lifetime attributes to different recipients based on their individual characteristics such as security clearance levels, device security settings, and recipient identifiers. Each recipient receives the same message content but with customized display duration and deletion timing, allowing the system to adapt to local security requirements without increasing overall system complexity
Solution Approach 2:
The system performs preliminary action by pre-defining message lifetime attributes and security parameters when the message is sent. The sender or system can specify different display durations, deletion times, and security clearances for each recipient in advance. This preliminary configuration eliminates the need for complex real-time decision-making, reducing system complexity while maintaining high adaptability
2Reliability
If message is stored on server for offline recipients, then message delivery reliability is improved, but security risk increases
Solution Approach 1:
The patent applies dynamics by making the message storage and deletion timing flexible rather than fixed. Messages stored on the server for offline recipients are automatically deleted after a predetermined time period or when security conditions change. The system dynamically adjusts storage duration based on recipient availability, security clearances, and message sensitivity, ensuring reliable delivery while minimizing security risks through automatic expiration
Solution Approach 2:
The system treats server-stored messages as temporary, disposable objects with limited lifetime. Rather than permanently storing messages for offline recipients, the system maintains them only for the minimum necessary duration to ensure delivery. Messages are automatically deleted after expiration, using server storage resources efficiently while reducing security risks associated with long-term message retention
3Ease of operation
If message display time is extended, then recipient convenience is improved, but security is compromised
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the message display duration parameter based on recipient attributes such as security clearance levels, device security settings, and message sensitivity. The system can set different display times for different recipients - longer display times for low-security contexts and shorter display times for high-security contexts. This parameter customization balances recipient convenience with security requirements, allowing each user to view messages for an appropriate duration without increasing interception risk
Data Source
AI summary
Systems and methods for direct packet communications and store and forward packet communications are provided that include packets which have attributes which determine the lifetime of the packet contents and these lifetimes are optionally a function of the recipient. Example methods are given featuring the transmission of packets with limited lifetime, the storing and retransmission of packets to one or more recipients and confirmation of deletion of packet contents. It is also shown that cryptography may be employed to ensure that timed presentation of packet contents to recipients takes place and is authenticated by the sender.
