Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods between portable terminals require complex authentication processes and inconvenient procedures, such as password input and search lists, making data transfer cumbersome.
Innovation Solution
A method and device that enable data transmission between portable terminals through a drag operation, using the time and speed of the drag to facilitate authentication and data transfer without the need for complex mutual authentication processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional near field communication is used for data transmission, then data can be transmitted between portable terminals, but the authentication process becomes complicated and inconvenient
Solution Approach 1:
The system performs authentication automatically based on the drag operation characteristics without requiring manual password input or complex mutual authentication procedures. The drag operation itself serves as the authentication mechanism, where the system extracts time and speed information to verify the connection between terminals.
Solution Approach 2:
The patent uses the time and speed parameters of the drag operation as authentication credentials. By extracting these physical parameters from the user's drag action, the system creates a unique authentication signature that verifies the intended data transmission without requiring traditional password-based authentication.
2Reliability
If traditional authentication procedures are implemented, then secure data transmission is achieved, but the overall transmission process becomes time-consuming
Solution Approach 1:
The authentication process is performed automatically and simultaneously with the data transmission initiation. The time and speed information from the drag operation is extracted and used for authentication verification in advance, eliminating the need for separate manual authentication steps that would delay the transmission process.
Solution Approach 2:
The patent replaces the mechanical/password-based authentication system with an automated parameter-based system. Instead of requiring manual password entry and verification, the system uses the temporal and kinematic parameters of the drag operation to automatically authenticate and initiate data transmission.
3Reliability
If manual password input is required for each terminal, then authentication control is maintained, but user convenience and ease of use deteriorates
Solution Approach 1:
The system automatically performs authentication based on the drag operation characteristics without requiring manual password input. The drag operation itself serves as the authentication mechanism, where the system extracts time and speed information to verify the connection between terminals, making the process fully automated and user-friendly.
Solution Approach 2:
The drag operation serves multiple functions simultaneously: it initiates the data transmission process and provides the authentication credentials. By using the same user action (drag) for both connection establishment and authentication, the system eliminates the need for separate password input steps while maintaining security.
Data Source
AI summary
A device and method for transmitting data can conveniently perform data transmission between two portable terminals. The device preferably includes a first portable terminal transmitting data on which a drag operation has occurred to a second portable terminal when the second portable terminal is coupled to the first portable terminal using a time and a moving speed of the drag operation when the drag operation occurs from the first terminal to the second portable terminal. The second portable terminal receives the data from the first portable terminal using the time and the moving speed of the drag operation when the drag operation occurs from the first portable terminal to the second portable terminal coupled to the first portable terminal through near field communication.
