Temporary Audio Streaming with Playback Restrictions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for sharing audio files are cumbersome and prone to unauthorized copying and dissemination, particularly in the music industry, where unreleased tracks can be leaked before intended release, impacting sales.
Innovation Solution
A system and method for temporarily sharing audio over a network, where a server manages audio sharing requests with restrictions on duration, number of plays, and recipient selection, using unique keys and watermarks to prevent recording and duplication, and automatically deletes the audio file after the specified time or play limit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio files are shared permanently via email attachment, then recipients can access and use the audio file indefinitely, but this allows unauthorized copying and dissemination of the audio
Solution Approach 1:
The system performs preliminary actions by embedding tracking mechanisms and restrictions into the audio file before sharing. The audio file is prepared with embedded metadata, serial numbers, and playback restrictions in advance, enabling the copyright owner to control dissemination before the actual sharing occurs. This preliminary preparation allows the system to enforce copyright control while maintaining ease of sharing through automated processes.
Solution Approach 2:
The system implements feedback mechanisms by tracking each playback of the shared audio file. The embedded serial number and tracking code provide feedback to the copyright owner about who is listening, when, and how many times. This feedback loop enables continuous monitoring and control of audio dissemination, allowing the system to maintain copyright control while facilitating sharing through the automated tracking and reporting system.
2Adaptability or versatility
If audio files are shared with multiple recipients via email, then the reach of the audio sharing increases, but the process becomes cumbersome due to locating email addresses and file size limitations
Solution Approach 1:
The system uses copying by distributing a standardized sharing message template that can be replicated and sent to multiple recipients simultaneously. Instead of individually attaching audio files to multiple emails, the system generates identical sharing messages with embedded tracking codes for each recipient, enabling efficient multi-recipient sharing while maintaining adaptability to different audience sizes through automated message distribution.
Solution Approach 2:
The system achieves universality by creating a multi-functional sharing platform that handles various sharing scenarios through a single interface. The same system can share audio with one recipient or thousands, distribute to different file formats, and manage various restriction types all through one unified process. This eliminates the need for separate processes for different sharing scenarios, enhancing both ease of operation and adaptability.
3Reliability
If audio files are made available for streaming with playback restrictions, then copyright control is improved, but the system complexity increases due to key management and verification processes
Solution Approach 1:
The system employs disposable short-living objects by using single-use playback keys and temporary access tokens. Each recipient receives a unique key that is valid for a specific number of playbacks or time period, after which it becomes useless. This approach provides strong playback control through cryptographic key management while keeping the system relatively simple because the keys are self-contained and do not require complex server-side verification for each playback event.
4Reliability
If the audio file is automatically deleted after a time restriction, then copyright protection is enhanced, but the automation requires additional system complexity
Solution Approach 1:
The system implements self-service by enabling the shared audio file to automatically enforce its own deletion schedule without requiring external intervention. The embedded metadata and timing mechanisms allow the audio file to self-manage its availability window, automatically becoming inaccessible after the specified time period or playback count. This self-service approach provides reliable temporary access control while minimizing system complexity by eliminating the need for external monitoring and manual deletion processes.

AI summary
Systems and methods presented herein may allow a sending user to stream audio to recipients without providing a permanent audio file, facilitating sharing of audio while retaining control over the audio file and reducing the chances of users copying the file. The sending user may specify number of plays, duration of time audio will be available for streaming, and the number of times the audio can be re-shared in one embodiment. The sending user and recipients may all execute a common client software on their computing devices that causes the computing devices to delete the audio when the streaming is complete and detect attempts to copy the audio at the device.
