Multifunction Printer Image Processing with Server DRM
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing distribution of high-resolution digital images over communication networks poses challenges for effective copyright protection, as existing systems struggle to prevent unauthorized duplication and management of image data across various devices, particularly in non-traditional distribution settings like multifunction printers.
Innovation Solution
An image processing system that communicates with a server for implementing copyright protection, featuring a reading unit, destination specification, data transmission to a server, and subsequent secure transmission to a user-specified destination, utilizing a digital rights management system to encrypt and manage image data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital image data is distributed over communication networks with higher resolution, then image quality is improved, but the amount of data increases making copyright protection more difficult
Solution Approach 1:
A server acts as an intermediary between the image data and the communication network. The server receives original high-resolution image data, generates encrypted version data with embedded rights management information, and distributes this protected data. This intermediary approach enables copyright protection without requiring complex protection mechanisms at each distribution point or device.
2Reliability
If copyright protection mechanisms are implemented to prevent unauthorized duplication, then security is improved, but the complexity of the image data processing system increases
Solution Approach 1:
Copyright protection measures are performed in advance before data distribution. The server embeds rights management information and encryption into the image data during the generation process, so that protected data is ready for distribution without requiring additional protection mechanisms at receiving devices. This preliminary action simplifies the overall system while maintaining security.
3Reliability
If traditional transfer devices are used for data distribution, then data security is maintained, but convenience for users to generate and distribute copyrighted data is reduced
Solution Approach 1:
The server provides a universal platform that handles multiple functions: receiving original data, generating encrypted versions, embedding rights management information, and distributing to various destinations. This multi-functional approach allows users to easily distribute copyrighted data through the server without needing to implement complex protection mechanisms themselves, while maintaining security through centralized control.
Data Source
AI summary
A multifunction printer, connected to a digital rights management (DRM) system through a network, has a reader unit for reading a document or a photograph as an image. The multifunction printer transmits data of the image to the DRM system. The DRM system converts the received image data into data in a DRM format. The multifunction printer enters the converted image data into a digital image data database and/or transmits the data to a destination.
