Policy-Based Printing and Scanning in Public Domains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing policy-based printing and scanning systems are limited to closed private domain environments, making it difficult for users who travel frequently to access and print or scan documents in public locations, as these locations often do not support policy-based operations.
Innovation Solution
A system that utilizes a public and private network to implement policy-based printing and scanning operations, where a private server generates policy values and sends them to a public server, allowing users to authenticate and execute scanning or printing jobs based on predefined policies, even in public domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If policy-based printing and scanning systems operate within a closed private domain environment, then security and policy compliance are maintained, but users cannot access printing and scanning services in public locations
Solution Approach 1:
The patent introduces a public domain server as an intermediary between users in public locations and the private domain policy-based printing system. This server receives print jobs from users, stores them temporarily, and forwards them to the private domain for processing, enabling public access while maintaining policy compliance through the intermediary layer
Solution Approach 2:
The system is divided into separate public and private domains with distinct functions. The public domain handles user authentication and job submission, while the private domain maintains policy enforcement and document processing. This segmentation allows users to access services in public locations while policy compliance remains enforced in the secure private environment
2Ease of operation
If users access printing services in public locations, then mobility and convenience are improved, but reliable access to printing data and policy support cannot be guaranteed
Solution Approach 1:
The system performs preliminary authentication and policy verification before allowing print jobs to be submitted from public locations. Users are authenticated against their organization's credentials, and their printing privileges are determined in advance, ensuring reliable access control even when users are mobile and in public locations
Solution Approach 2:
The public domain server creates a temporary copy of the print job data for storage and processing in the public domain, while the original data remains in the private domain. This copying mechanism enables users to access printing services in public locations while maintaining reliable access to the original printing data through the network connection to the private domain

AI summary
A policy-based system is implemented to allow access to a private domain to print using a public domain. The private domain includes private servers that store documents. The public domain includes servers and a printing device. A public policy server uses a domain list and a protocol connection with a private authentication server to validate a user and identify which private domain to access. The public policy server receives requests from the printing device to process a print job of a document in the private domain. The policy-based system also determines whether scanning operations for a document are allowed for a user at a scanning device. The private policy server determines policy values that are used to allow the scanning operations.
