Media Security System Asynchronous Content Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current media distribution systems face challenges in managing the simultaneous download of large files across bandwidth-constrained connections, leading to resource strain during public releases of content like press releases and movie premieres, as existing encryption systems do not effectively manage key distribution and decryption timing.
Innovation Solution
A media security system comprising a security server that generates time-stamped public and private encryption keys, allowing secure media packages to be accessed by clients before the decryption key is available, reducing bandwidth strain by enabling asynchronous downloads and controlled content release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is released simultaneously to multiple clients at the designated time, then all clients can access the content at the proper time, but bandwidth resources are significantly strained due to simultaneous downloads
Solution Approach 1:
The patent applies preliminary action by allowing clients to download encrypted content packages before the designated release time. The content is encrypted with a public key during this preliminary phase, so clients can retrieve and store the content without straining bandwidth resources at the actual release moment. The decryption key is then distributed at the designated time, enabling all clients to decrypt and access the content simultaneously without download conflicts.
2Loss of energy
If content is downloaded ahead of time by multiple clients, then bandwidth strain is reduced, but content security is compromised if decryption keys are available too early
Solution Approach 1:
The patent segments the content distribution process into two distinct phases: (1) encrypted content distribution phase, where content is downloaded ahead of time using public key encryption, and (2) decryption key distribution phase, where the private decryption key is distributed at the designated release time. This segmentation allows bandwidth optimization in the first phase while maintaining security in the second phase, as the decryption key remains unavailable until the proper time.
Solution Approach 2:
The patent introduces public key encryption as an intermediary mechanism that enables early content distribution without compromising security. The public key acts as a mediator that allows clients to encrypt and store content before the release time, while the private key (which remains secure until the designated time) is required for decryption. This intermediary encryption system bridges the gap between early download benefits and security requirements.
3Reliability
If large files are distributed simultaneously to multiple clients, then all clients receive the content at the proper time, but download time becomes significant due to file size and bandwidth constraints
Solution Approach 1:
The patent applies preliminary action by performing the content download operation before the designated release time. Clients download the encrypted content packages in advance when bandwidth resources are more abundant and download times are not critical. This shifts the time-consuming download operation to a preliminary phase, allowing the actual release moment to be dedicated solely to key distribution and content access, thereby reducing perceived download time for users.

AI summary
The present specification provides, amongst other things, a system for offering the capability to asynchronously upload secure media packages to client machines and providing for recovery of the media packages in playable (or other usable form) only at a predefined time, so that the client machines can all access the media packages only at or after the predefined time.
