Lock Screen Authentication via Intra-Body Communication Gesture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing apparatuses, such as multifunctional devices and smartphones, require users to take extra steps for user authentication after unlocking, which is not user-friendly, even when techniques allow for one-gesture unlocking and function selection.
Innovation Solution
Implementing a touch-enabled display with a lock screen that includes an unlock icon and function icons, where user authentication is conducted via intra-body communication technology, allowing users to unlock and select functions with a single gesture without additional authentication steps, and displaying permitted functions in a visually distinct manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication is required after unlocking, then security is improved, but ease of operation deteriorates due to extra steps
Solution Approach 1:
The patent merges the authentication process with the unlock gesture by detecting user identity through intra-body communication during the swipe gesture itself. The authentication result determines which screen is displayed after unlocking, eliminating the need for a separate authentication step while maintaining security.
Solution Approach 2:
The system performs authentication in advance by detecting the user's identity through intra-body communication before the unlock gesture is completed. The authentication result is ready when the gesture ends, allowing the appropriate screen to be displayed immediately without requiring post-unlock authentication.
2Adaptability or versatility
If multiple screens are displayed based on authentication, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system dynamically displays different screens (first screen or second screen) based on the authentication result obtained during the unlock gesture. The display content adapts to the user's identity and authentication status without requiring complex manual configuration or additional user input.
Solution Approach 2:
The system automatically performs authentication and screen selection based on detected user identity, eliminating the need for users to manually configure or navigate through multiple authentication screens. The apparatus serves itself by making intelligent decisions about which screen to display.

AI summary
An information processing apparatus (1) comprises: a touch-enabled display means (22); a lock means (3) that locks the information processing apparatus (1); a display control means (35) that displays a lock screen on the display means (22), the lock screen having a first icon (221) for unlock and one or more second icons (222a)∼(222f) each representing a function, and that refreshes the lock screen, when a user moves the first icon (221), such that the first icon (221) is present at a different position; an unlock means (3) that unlocks the information processing apparatus (1); a recognition means (3) that recognizes a function as being selected, the function being represented by the one second icon or one of the second icons (222a)∼(222f) being present at the position where the user releases the first icon (221); a user information obtaining means (36) that obtains user information; and an authentication means (38) that conducts user authentication with the obtained user information while the user is moving the first icon (221).
