Client Decryption Release Timing for Synchronized Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to achieve simultaneous secure delivery of decrypted electronically stored content to multiple client computers located remotely due to geographical and computing capability variations, leading to discrepancies in delivery times.
Innovation Solution
A method, system, and software that utilize operating variable information to calculate a release time for each client computer to initiate decryption, accounting for network latency, computing capabilities, and other latencies, ensuring simultaneous secure delivery across a network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content is delivered to multiple remote client computers over the Internet, then content dissemination capability is improved, but delivery time discrepancy increases due to network latency and geographical variations
Solution Approach 1:
The system performs preliminary actions by encrypting the content before distribution and pre-calculating or dynamically determining release times for each client computer. The encrypted content is made available to all clients in advance, but decryption is triggered simultaneously at a predetermined release time, eliminating delivery time discrepancies while maintaining global dissemination capability
Solution Approach 2:
The content delivery engine acts as an intermediary between the content source and multiple client computers. It receives encrypted content, determines appropriate release times for each client based on their characteristics, and coordinates the decryption process. This intermediary manages the complexity of simultaneous delivery to multiple remote clients without requiring direct peer-to-peer synchronization
2Reliability
If decryption is performed at each client computer, then security is improved, but delivery time discrepancy increases due to varying computing capabilities
Solution Approach 1:
The system changes the parameter of decryption timing from client-dependent to centrally-coordinated. By determining release times that account for each client's computing capabilities and network conditions, the system ensures that despite variations in hardware performance, all clients complete decryption simultaneously. The security of local decryption is maintained while the timing parameter is optimized for simultaneity
3Loss of time
If simultaneous decryption is enforced across all clients, then delivery simultaneity is improved, but system complexity increases due to coordination requirements
Solution Approach 1:
The content delivery engine performs preliminary actions by pre-establishing release times for each client computer before the actual content distribution. This preliminary coordination phase handles the complexity of calculating and communicating release times, while the actual content delivery and decryption process becomes straightforward for each client - they simply wait for their predetermined release time and execute decryption automatically
Solution Approach 2:
Each client computer is equipped with the encrypted content and decryption instructions in advance. At the predetermined release time, each client independently performs decryption without requiring real-time coordination or communication with other clients. The complexity of simultaneous coordination is resolved in advance, allowing each client to serve itself autonomously at the moment of decryption

AI summary
A computer-implemented method (and associated system and software) of providing simultaneous secure delivery of decrypted electronically stored content to remotely located client computers via an electronic communication network. The method includes acquiring operating variable information about client computers; calculating a release time when decryption is enabled for each client computer to start decrypting a first byte of a set of encrypted electronic content units obtained by such client computer; and transmitting computer-executable instructions to begin decryption at the release time so that each client computer is securely delivered decrypted content simultaneously.
