Encrypted Digital Media Licensing via Context Menu
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital media creators face challenges in protecting their work from unauthorized use and distribution, as existing watermarking solutions do not effectively prevent copying, and copyright laws provide limited legal recourse, making it difficult for creators to promote their work while preventing misuse.
Innovation Solution
A method of encrypting digital media files with a context menu that includes a licensing screen, allowing users to obtain licenses with customizable terms, and tracking usage to prevent unauthorized access, copying, and display based on license conditions, including encryption keys for decryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital media is published without protection, then it can be promoted and viewed by potential licensees, but it can be copied and misappropriated unauthorized
Solution Approach 1:
The patent applies preliminary action by encrypting the digital media file before publication, so that the protective measure is already in place when the file is shared. The file is encrypted with encryption software and distributed in encrypted form, preventing unauthorized access while allowing legitimate viewing through license keys.
Solution Approach 2:
The patent uses an intermediary approach by introducing a license key system as a mediator between the encrypted media and the user. The license key acts as an intermediary credential that must be obtained through proper licensing channels, enabling authorized access without exposing the media to unauthorized copying.
2Loss of information
If watermarking is applied to protect digital media, then ownership information is retained, but the media quality is degraded and copying is not prevented
Solution Approach 1:
The patent extracts the ownership protection function from the media content itself and places it in a separate licensing system. Instead of embedding watermarks in the media, the ownership information is stored separately and verified through license keys, allowing the media to remain high-quality while ownership is protected through the external licensing mechanism.
Solution Approach 2:
The patent introduces a license key as an intermediary that carries ownership verification information separately from the media content. This intermediary system allows ownership information to be retained and verified without degrading the media quality or relying on embedded watermarks that can be removed.
3Object-affected harmful factors
If encryption is applied to protect digital media, then unauthorized copying is prevented, but the licensing process becomes complex
Solution Approach 1:
The patent applies self-service by enabling the encrypted media file to automatically manage its own licensing through an embedded context menu. When a user right-clicks on the encrypted file, a context menu appears with a licensing option that automatically initiates the licensing process, eliminating the need for complex manual licensing procedures.
Solution Approach 2:
The patent merges the licensing functionality directly into the encrypted media file by embedding a context menu with licensing options. This combines the file access and licensing operations into a single integrated interface, simplifying the user experience while maintaining security.
4Ease of operation
If a context menu with licensing screen is embedded in encrypted files, then licensing is simplified for users, but the file format becomes more complex
Solution Approach 1:
The patent merges the licensing interface directly into the encrypted file by embedding a context menu that appears when the user right-clicks on the file. This integration combines the file access and licensing operations into a single unified interface, making licensing as easy as a simple click while the underlying file format complexity is handled automatically by the encryption software.

AI summary
Disclosed are systems, apparatus, and methods for protecting digital media. An exemplary method includes receiving digital media, encrypting the digital media using an encrypted file format to generate an encrypted file, displaying a context menu when the encrypted file is accessed, the context menu including a licensing screen, enabling a user to obtain a license to the digital media using the licensing screen of the context menu, and configuring the encrypted file to enable access to the digital media based on a term of the license.
