Rendezvous Session Integrity via Distributed Hash Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital data processing systems lack effective measures to ensure user safety during personal rendezvous sessions, particularly in preventing unauthorized intrusion, data modification, or tampering, and providing a reliable forensic record of interactions.
Innovation Solution
A system that uses a user's portable device to initiate a monitored and reconstructible personal rendezvous session, tracking location and recording all communications in real-time, with data stored remotely and time/date stamped to prevent alteration or deletion, providing an unmodifiable chain of evidence for user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If session data is stored locally on user devices, then data accessibility is improved, but data integrity and protection from tampering deteriorates
Solution Approach 1:
The patent extracts the critical function of data integrity verification from local storage by implementing a distributed hash verification system. Each user device stores a hash of the session data on the server, allowing local accessibility while enabling remote verification of data integrity without requiring centralized control.
Solution Approach 2:
The patent implements local quality by allowing each user device to independently verify session data integrity using its own stored hash values. This enables each participant to have local confidence in data integrity without requiring a trusted central authority, resolving the contradiction between local accessibility and reliable verification.
2Reliability
If a central authority controls session data, then data security is improved, but trust and neutrality deteriorates
Solution Approach 1:
The patent segments the security verification function across multiple independent user devices rather than concentrating it in a central authority. Each device independently verifies data integrity using cryptographic hashes, distributing trust and eliminating the need for a potentially biased central controller while maintaining security.
Solution Approach 2:
The patent introduces cryptographic hash functions as an intermediary mechanism that enables security verification without requiring trust in any single party. The hash values act as neutral mediators that all participants can independently verify, eliminating bias while maintaining data security.
3Adaptability or versatility
If session data can be modified for flexibility, then adaptability is improved, but forensic reliability deteriorates
Solution Approach 1:
The patent performs preliminary action by computing cryptographic hash values of session data immediately upon generation and storing them on the server. This preliminary hashing action creates an immutable reference that preserves forensic integrity while allowing the actual session data to remain flexible and modifiable during the session.
4Reliability
If monitoring is implemented to ensure safety, then user protection is improved, but privacy and anonymity deteriorates
Solution Approach 1:
The patent creates cryptographic copies (hashes) of session data for verification purposes without requiring access to or storage of the actual private information. These hash copies enable safety monitoring and integrity verification while preserving the privacy and anonymity of the underlying session content.

AI summary
Disclosed is a system that adapts a personally portable “smart” communications device to enhance a user's personal security by continuously monitoring an alert function of the device from a remote location during a user initiated “session.” The user device is in communications with a remote server, which monitors the alert function and provides: accurate preservation of session data; monitoring of user device ambient conditions; dispatch of emergency services; and notification of third parties. Server software (host application) on the remote server manages communications with user devices. The server collects, processes and stores data; dispenses data according to a rule set, and manages multiple user sessions. User software manages the initiation and conduct of a session and communications with the server. The user and server software in combination provide for establishing, maintaining operations of the system, and databases accessible by the remote server for storage/archiving of system data.
