Image Forming Apparatus Data Transmission Security Policy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network scan methods for image forming apparatuses lack security restrictions, making it easy to leak confidential data during transmission.
Innovation Solution
Implementing a data transmission method that receives identification information of a destination and determines whether to transmit data based on a security policy, using a user interface to input and manage destination information, and storing allowed destinations in an address list database to prevent unauthorized data leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network scan method is used to transmit scanned image files, then data transmission convenience is improved, but data security deteriorates due to lack of transmission restrictions
Solution Approach 1:
The patent applies preliminary action by establishing a security policy and address list database before data transmission occurs. The system pre-determines which destinations are authorized for data transmission and stores this information in advance, so that when transmission is requested, the decision is already made based on pre-established security rules rather than real-time evaluation.
Solution Approach 2:
The patent introduces an intermediary mechanism in the form of a transmission possibility determining unit that acts as a mediator between the data transmission request and the actual transmission. This intermediary unit checks the destination against the security policy and address list database before allowing transmission to proceed, thereby controlling and monitoring the transmission process.
2Object-affected harmful factors
If security policy is implemented to restrict data transmission destinations, then data security is improved, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The patent applies segmentation by dividing the security control function into distinct components: a user interface unit for receiving destination information, a transmission possibility determining unit for evaluating security policies, and a data transmission unit for executing authorized transmissions. This segmentation allows each component to perform its specific function independently, making the overall system more manageable despite the added complexity.
Solution Approach 2:
The patent uses a database to store and copy the security policy and address list information, rather than repeatedly evaluating complex rules during each transmission. By copying the authorized destinations into a database structure, the system simplifies the transmission decision process to a straightforward lookup operation.
3Reliability
If address list database is used to store authorized destinations, then transmission reliability is improved, but loss of time increases due to destination verification process
Solution Approach 1:
The patent applies preliminary action by pre-storing authorized destinations in the address list database before transmission occurs. This allows the system to quickly retrieve and verify destination authorization status during transmission without performing complex real-time evaluation, thus reducing verification time while maintaining high reliability.
Data Source
AI summary
A method of transmitting data from an image forming apparatus, the method including: receiving identification information of a destination of the data; determining whether to transmit the data to the destination corresponding to the received identification information based on a security policy of the image forming apparatus; and transmitting the data to the destination in response to the destination being determined to be a destination to where the data is allowed to be transmitted, based on the security policy.
