Information Reader Using State Data for Flexible Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information readers fail to utilize the positional relationship or environmental state information as meaningful data during the image reading process, limiting the flexibility and security of information acquisition.
Innovation Solution
An information reader system that includes an object reading unit, state data obtaining unit, and identifying unit to analyze and utilize state data such as positional relationship, angle, and environmental conditions to generate new information, allowing for secure and flexible information handling without additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional information readers are used to read object images, then information can be obtained within a certain position and angle range, but the information remains unchanged and cannot be modified through simple operations
Solution Approach 1:
The patent applies parameter changes by utilizing reading state parameters (position, angle, environmental conditions) to dynamically change the information output. Instead of keeping information fixed, the system varies information presentation based on reading state parameters, achieving information flexibility without adding complex hardware.
2Reliability
If authentication procedures are added to restrict information acquisition, then security is improved, but the operation process becomes more complex
Solution Approach 1:
The patent applies self-service by using reading state parameters themselves as authentication keys. The system automatically determines whether to release information based on the detected reading state, eliminating the need for separate authentication procedures while maintaining security.
3Measurement precision
If state data such as position and angle are used only for correction, then reading accuracy is maintained, but the data cannot be used as meaningful information
Solution Approach 1:
The patent applies multi-functionality by making reading state parameters serve dual purposes: they are used both for correcting reading accuracy and as meaningful information for identifying processing targets. This eliminates information loss by utilizing the same data for multiple functions.
Data Source
AI summary
An information reader includes an object reading unit for reading an image of an object and obtaining the image as image data, an object data obtaining unit for analyzing the image data and obtaining object data as data contained in the object itself, a state data obtaining unit for obtaining state data indicating a state of the object during object image reading operation to read an image of the object, and an identifying unit for identifying predetermined processing by using as identification data the object data and at least one of the state data. The information which is obtained when an object is shot and which is meaningless in the conventional techniques can be effectively used. Therefore, the quantity of overall information can be increased without adding new hardware to the information reader.
