Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gesture password input interfaces are undiversified, making them vulnerable to attacks and resulting in low authentication reliability due to familiarity among attackers.
Innovation Solution
A method and device that utilize a picture specified by the user as a gesture password input interface, where interactive operations on the picture are detected and used to generate standard information for authentication, increasing the difficulty for attackers to replicate the gesture password.

Engineering Contradiction Analysis
1Reliability
If a traditional nine-box grid gesture password input interface is used, then the interface is simple and easy to implement, but the authentication reliability is low because attackers are familiar with it and can easily memorize or crack the password
Solution Approach 1:
The patent changes the fundamental parameter of the input interface from a fixed nine-box grid structure to a flexible picture-based structure. Users can select from multiple pictures (e.g., photos, icons, drawings), and each picture provides different feature areas for gesture input. This parameter change diversifies the interface while maintaining ease of use through familiar interaction patterns like tapping and swiping on visually appealing images.
Solution Approach 2:
The system transitions from a static nine-box grid to a dynamic picture-based interface where the arrangement, number, and positions of feature areas can vary based on the selected picture. The feature areas are determined dynamically through image processing algorithms that identify key points, contours, or regions of interest in each picture, making the interface adaptable and less predictable for attackers.
2Reliability
If the gesture password input interface is diversified using pictures, then authentication reliability improves, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The system performs preliminary actions by pre-processing pictures to identify and mark feature areas before the actual authentication process. Image processing algorithms analyze the selected picture in advance to determine optimal feature areas, store their coordinates, and prepare the data structure for gesture recognition. This preliminary processing reduces the complexity during real-time authentication by having the heavy computational work done beforehand.
Solution Approach 2:
The picture-based interface serves multiple functions simultaneously: it acts as both the visual stimulus for user interaction and the source of authentication data. The feature areas extracted from the picture automatically provide the coordinate system for gesture recognition, eliminating the need for separate interface elements and reducing overall system complexity.

AI summary
The present application discloses an authentication method and device, and a method and a device for generating information for authentication, to alleviate a problem of relatively low authentication reliability caused by undiversified gesture password input interfaces in the existing technology. The authentication method includes the following: displaying a picture pre-specified by a first user; detecting an interactive operation of a second user for the picture; generating interactive operation information of the second user based on the detected interactive operation of the second user; and performing authentication to determine whether the second user is the first user by matching the interactive operation information of the second user and standard information, where the standard information is generated based on an interactive operation of the first user for the picture.
