Detached Operating Terminal Authentication for Networked Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing systems lack a mechanism for an operating unit detached from a device main body to issue processing requests to device main bodies on a network, similar to a terminal.
Innovation Solution
An information processing system comprising a device and a terminal with units for authentication, identification, and execution request handling, where the terminal generates and sends authentication and execution requests, and the device receives, authenticates, and processes these requests, allowing the terminal to control device operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an operating unit is detached from a device main body, then the operating unit can be used independently, but there is no mechanism for it to issue processing requests to device main bodies on the network
Solution Approach 1:
The patent copies the authentication and identification mechanisms from terminal devices and applies them to the detached operating unit. The operating unit obtains authentication information and generates execution requests with identification information, replicating terminal behavior to enable network communication without requiring complex new mechanisms
Solution Approach 2:
The detached operating unit is designed to perform multiple functions: it can obtain authentication information, generate execution requests with identification information, and communicate with device main bodies on the network. This universal design allows a single component to replace both traditional terminal functions and local operating unit functions
2Reliability
If authentication information is transmitted from terminal to device, then secure access is enabled, but additional communication steps are required
Solution Approach 1:
Authentication information is obtained and verified before the execution request is processed. The device main body receives authentication information, verifies it against stored credentials, and only then processes the execution request. This preliminary authentication ensures security while establishing a clear sequential process that minimizes unnecessary delays
3Adaptability or versatility
If the operating unit generates execution requests with identification information, then user-specific operations are enabled, but the processing complexity increases
Solution Approach 1:
The execution request is segmented into distinct components: identification information and operation instructions. The device main body processes these segments separately - first verifying the identification information against stored user credentials, then executing the specific operation. This segmentation simplifies the processing logic compared to handling monolithic requests

AI summary
A first obtaining unit obtains authentication information. A first sending unit sends the authentication information. A generating unit generates an execution request. A second sending unit sends the execution request. A device includes a first holding unit holding authentication information registered in advance; an authenticating unit performing an authentication operation by determining whether one or more sets of authentication information held by the first holding unit include authentication information matching with authentication information received by a first receiving unit; a second holding unit holding identification information of the authenticated user; and a control unit performing, when identification information included in the execution request received by a second receiving unit matches with identification information held by the second holding unit, control to perform operations based on the execution request, and, when the two sets of identification information do not match, control to request the information processing terminal for the authentication information.
