Image Sequence Password Authentication System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in creating and remembering passwords due to increasing security requirements, which existing authentication methods fail to address effectively.
Innovation Solution
A computer-implemented method that presents a plurality of images in random order, allowing users to select a set of images and their sequence to form a password, which is then used for authentication, thereby increasing security and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional password methods are used, then ease of operation is maintained, but security is insufficient
Solution Approach 1:
The patent replaces traditional text-based password input (mechanical keyboard typing) with image-based selection and sequence indication. Users interact by selecting images from displayed sets and indicating their sequence, substituting the mechanical typing process with visual selection and digital input, thereby enhancing security while maintaining ease of operation.
Solution Approach 2:
The patent changes the fundamental parameter of password representation from alphanumeric characters to image sequences with positional information. By transforming the password from a text string to a structured sequence of image selections with associated position indicators, the system increases complexity and security while preserving user-friendly interaction through visual interfaces.
2Reliability
If password complexity is increased to improve security, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent substitutes the need to remember complex alphanumeric passwords with a visual memory task. Users remember sequences of images and their positions rather than random character strings, leveraging the human brain's superior visual memory capabilities to maintain ease of operation while achieving high security through increased password complexity.
3Reliability
If more images are presented to increase password complexity, then security is improved, but device complexity increases
Solution Approach 1:
The patent segments the authentication process into distinct phases: image presentation, image selection, sequence indication, and verification. By dividing the complex authentication task into manageable segments, the system achieves high security through multiple decision points while keeping each individual interaction simple and the overall device complexity controlled.
Solution Approach 2:
The patent adds a temporal/positional dimension to image selection by requiring users to indicate the sequence or position of selected images. This transforms a simple selection task into a multi-dimensional authentication mechanism where both what images are selected and in what order they are selected contribute to the password, increasing security without proportionally increasing device complexity.

AI summary
User authentication is facilitated. A plurality of images on one or more display levels is presented to a user in random order. A password is received from the user, and the password includes a set of images selected from the plurality of images and an indication of a particular sequence of the images in the set of images. A determination is made as to whether the password matches a predefined password, and access is provided based on determining there is a match of the password and the predefined password.
