Cloud File Access via Metadata Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cloud-based print control systems face issues with data integrity and confidentiality, high bandwidth consumption, and service unavailability due to the need to transfer large print jobs over wide area networks, which increases costs and user experience hampering latency.
Innovation Solution
A system that stores files locally and transmits only meta-data files to master servers worldwide, allowing users to access and process files efficiently without storing large files in data centers, reducing storage costs and enhancing security by keeping sensitive information local.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If print jobs are transferred to the cloud for processing, then users can access files from anywhere, but bandwidth consumption increases and transmission latency worsens
Solution Approach 1:
The patent extracts only the essential metadata from complete print jobs and transfers only this extracted information to the cloud. The metadata includes document properties, formatting instructions, and routing information, while the actual large print job data remains locally stored. This extraction approach enables cloud-based file access management while minimizing bandwidth consumption to only the small metadata portions.
2Extent of automation
If print jobs are transferred to the cloud, then centralized control is achieved, but data confidentiality and integrity are compromised
Solution Approach 1:
The patent segments print job data into two distinct parts: metadata and actual content. The metadata (containing only document properties and control information) is transferred to the cloud for centralized management and processing, while the sensitive actual print job content remains locally stored in the organization's infrastructure. This segmentation allows centralized control over document properties and routing while keeping confidential data on-premises.
3Adaptability or versatility
If large files are stored in data centers, then global access is enabled, but storage costs increase
Solution Approach 1:
The patent extracts and transfers only the small metadata portions of documents to cloud data centers, while the large actual file content remains stored locally in the organization's infrastructure. The metadata contains document properties, formatting information, and access control data that are essential for cloud-based processing and global access management, but occupy minimal storage space compared to the full documents.
4Reliability
If print jobs are routed through the cloud, then service availability is improved, but network latency increases
Solution Approach 1:
The patent extracts only the small metadata from print jobs and transfers this extracted information through the cloud for processing. Since metadata is minimal in size compared to full print jobs, the transmission time and network latency are dramatically reduced while still enabling cloud-based service availability, centralized control, and global access capabilities.

AI summary
The present invention relates to a system for transmission of files, which files arc generated by a first user at a first client station, which first client station is connected by a first computer network such as a Local Area Network (LAN) to one or more local servers, which first server performs communication to a number of computer systems connected to the first LAN. It is the object of the invention to achieve worldwide net scalable files transferring processes without the need for transferring the files over the wide area net, but to retain the user's full access to any file. A further object of the invention is to prevent storage of large files at a plurality of servers during and after data transmission. The object can be fulfilled by a system or a method whereby the first server generate and transmit at least one meta data file related to file stored in the data cache by the Internet to at least one Master Server Unit (MSU), which MSU is part of a corporate or public data centre (CDC) to which CDC a number of second servers are communicating, which first user or a number of users can access the meta data file related to the file by any client station by any LAN connection to any of the second servers.
