EDP Control Unit for Secure Print Job Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security standards for triggering print jobs in computer networks are not meeting the highest security requirements, particularly in the authentication process.
Innovation Solution
An EDP control unit with a user authentication system, utilizing biometric methods such as palm vein recognition, fingerprint, retina, iris, or voice recognition, combined with a scanner, smart card reader, and PIN query, is implemented to securely select and transmit print jobs to target devices after user authentication, allowing for dynamic target device selection and enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a print job is pre-selected and made available at a target device before authentication, then the ease of operation is improved, but the security is worsened
Solution Approach 1:
The print job is prepared and staged in advance in the EDP control unit's buffer, but the actual transmission to the target device is delayed until authentication occurs. This preliminary preparation maintains ease of operation while the delayed execution ensures security.
Solution Approach 2:
The EDP control unit acts as an intermediary between the client and the target device. It receives the print job, buffers it, performs authentication, and then transmits the job to the selected target device. This intermediary role allows the system to balance ease of operation with security by controlling when and how the job reaches the target device.
2Ease of operation
If a target device is selected in advance for job execution, then the ease of operation is improved, but the adaptability is worsened
Solution Approach 1:
The target device selection is made dynamic rather than static. The EDP control unit allows the user to select the target device at the time of authentication, not in advance. This dynamic approach maintains ease of operation through a simple authentication process while improving adaptability by allowing flexible device selection based on current needs.
Solution Approach 2:
The system allows the user to self-select the target device during the authentication process. The EDP control unit presents the authentication interface and allows the user to choose which device should receive the print job, eliminating the need for pre-selection while maintaining ease of operation.
3Reliability
If biometric authentication systems are implemented, then the security is improved, but the device complexity is worsened
Solution Approach 1:
The EDP control unit combines multiple authentication methods (biometric sensors, smart card readers, PIN queries) into a single integrated device. This merging approach improves security by offering multiple authentication options while managing device complexity through unified control and a single point of interaction for the user.
Solution Approach 2:
The EDP control unit is designed as a multi-functional device that can perform various authentication methods (fingerprint, palm vein, retina, iris, voice recognition, smart card, PIN). This universality improves security by providing multiple authentication pathways while avoiding the need for separate dedicated devices for each authentication method, thus managing complexity.
