Image-Based Authentication Using Visual Passcode Sequences
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in remembering and managing numerous alphanumeric passwords across different computing devices and web accounts due to varying security requirements, leading to inconvenience and security risks from forgotten passwords.
Innovation Solution
Implementing image-based passcode authentication systems that allow users to generate and recall passcodes as sequences of images forming a sentence, which are more intuitive and easier to remember, using a device to select images corresponding to a predefined sentence structure for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional alphanumeric passwords are used for authentication, then security requirements can be met, but users face difficulty in remembering and managing multiple passwords
Solution Approach 1:
The patent replaces the traditional text-based password system with an image-based authentication system. Instead of using alphanumeric characters that are difficult to remember, the system uses visual images arranged in sequences to represent passcodes. This substitution leverages the human visual system's superior memory capabilities while maintaining authentication security through complex image sequence verification.
Solution Approach 2:
The patent changes the fundamental parameter of password representation from textual (alphanumeric) to visual (image-based). By transforming the authentication credential from text to images, the system exploits the picture superiority effect where humans naturally remember visual information better than text, thereby solving the recall difficulty while maintaining security through sophisticated image sequence validation.
2Reliability
If multiple complex passwords are required for different devices and accounts, then security requirements are satisfied, but user convenience deteriorates
Solution Approach 1:
The patent creates a universal image-based authentication system that can be applied across multiple devices and accounts. The image sequence passcode system serves as a multi-functional solution that replaces numerous device-specific alphanumeric passwords with a single, memorable visual system that works universally across different platforms and services.
Solution Approach 2:
The patent uses image copying and representation to create visual mnemonics. By associating images with personal memories or creating visual stories, users can recall passcodes more easily. The system copies visual information into human memory in a way that is more efficient than text-based recall, reducing the time needed to remember and enter passwords.
3Reliability
If alphanumeric passwords with varying character requirements are imposed, then security is enhanced, but ease of entry and recall is reduced
Solution Approach 1:
The patent substitutes the complex mechanical system of alphanumeric password construction with a visual system. Instead of requiring users to create passwords with specific character types, lengths, and complexity requirements, the system uses image selection and sequencing that is visually intuitive while maintaining equivalent or superior security through the complexity of image sequence verification.

AI summary
Systems and methods for authenticating a user are provided. A method may comprise providing interactive media on a computing device associated with a user. The interactive media may comprise a plurality of images. The plurality of images may be presented on a graphical display of the computing device. The method may also comprise receiving input data from the computing device when the user selects a sequence of images from the plurality of images on the graphical display of the computing device. The selected sequence of images may correspond to a sequence of grammatical words. The method may further comprise analyzing the input data by comparing the sequence of grammatical words to a passcode, and authenticating the user when the sequence of grammatical words is equal to the passcode.
