Reading System User Authentication and Permission Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current reading systems lack effective mechanisms for securely managing user permissions and authentication across different users and devices, leading to potential unauthorized access and inefficient communication in multi-user environments.
Innovation Solution
A reading system comprising a reading apparatus and a terminal apparatus that utilize identification, authentication, and permission units to securely manage user permissions, where the terminal apparatus transmits instructions to the reading apparatus only if the identification information of both users satisfies a certain condition, ensuring authorized access and reducing communication load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the reading apparatus accepts instructions from any terminal apparatus, then the ease of operation is improved, but the security and reliability deteriorate due to potential unauthorized access
Solution Approach 1:
An authentication unit is introduced as an intermediary between the terminal apparatus and the reading apparatus. This authentication unit verifies authentication information (such as passwords or biometric data) before allowing the reading unit to execute instructions, thereby maintaining ease of operation while ensuring security through a mediating verification layer
Solution Approach 2:
Authentication is performed in advance before the reading operation commences. The authentication unit verifies user credentials beforehand, and only after successful authentication does the reading unit proceed with the instructed operation, preventing unauthorized access while maintaining operational convenience
2Productivity
If the reading apparatus processes all received instructions, then the productivity is improved, but the loss of energy increases due to processing invalid or unauthorized instructions
Solution Approach 1:
Authentication verification is performed preliminarily before the reading unit processes instructions. By checking authentication information in advance, the system avoids wasting energy on processing invalid or unauthorized instructions, while still maintaining high productivity for authenticated legitimate operations
Solution Approach 2:
The authentication verification step is extracted and separated from the main reading operation flow. This allows the system to filter out invalid instructions before they reach the energy-intensive reading unit, reducing unnecessary energy consumption while preserving productivity for valid operations
3Reliability
If the system transmits authentication information for every operation, then the reliability is improved, but the communication network load increases
Solution Approach 1:
Authentication information is transmitted and verified in advance before the actual reading operation. Once authenticated, the reading apparatus can process multiple subsequent instructions without requiring repeated authentication transmissions, thereby maintaining security while reducing overall communication network load
Solution Approach 2:
Instead of transmitting authentication information for every single operation, the system performs authentication once preliminarily and then allows a series of operations under that authenticated session. This partial authentication approach maintains reliability while significantly reducing the quantity of authentication data transmitted over the network

AI summary
A reading system includes a reading apparatus and a terminal apparatus. The reading apparatus includes following components. An identification unit identifies a first user. A reading unit reads an original document. A reception unit receives, from the terminal apparatus, authentication information of a second user and an instruction. An authentication unit performs authentication using the authentication information. A permission unit permits, if authentication is successful, the reading unit to read an original document in accordance with the instruction. The terminal apparatus includes following components. A first acquisition unit acquires, from the reading apparatus, identification information of the first user. The acceptance unit accepts an operation of the second user. The second acquisition unit acquires identification information of the second user. The transmission unit transmits, if the pieces of identification information satisfy a certain condition, an instruction corresponding to the accepted operation and the authentication information to the reading apparatus.
