Contextual Authentication via Conversational Characteristics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication mechanisms rely heavily on passwords, which are insecure and cumbersome, leading to a need for supplementary or alternative authentication methods that have not gained widespread adoption due to cost and complexity issues.
Innovation Solution
The implementation of a multi-application contextual authentication system that uses pre-authentication techniques based on conversational characteristics across different applications, leveraging network connectivity to provide an automated and unobtrusive contextual authentication factor, which can be used alone or in combination with other factors, to facilitate secure and transparent authentication decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional password-based authentication is used, then ease of operation is improved, but reliability deteriorates due to security vulnerabilities
Solution Approach 1:
The patent introduces a biometric authentication intermediary (fingerprint sensor, voice recognition, or facial recognition system) that mediates between the user and the authentication system. This intermediary captures biometric data, processes it through authentication algorithms, and provides a security verification mechanism that is both reliable and user-friendly, thereby resolving the contradiction between ease of operation and reliability.
Solution Approach 2:
The patent replaces the mechanical/password-based authentication system with a biometric authentication system. Instead of relying on users to remember and input passwords (mechanical interaction), the system uses biological characteristics (fingerprint patterns, voice waveforms, facial geometry) captured by sensors and processed through recognition algorithms, thereby enhancing reliability while maintaining ease of operation.
2Reliability
If biometric authentication systems are implemented, then reliability is improved, but device complexity worsens
Solution Approach 1:
The patent implements a multi-functional authentication system that can operate in multiple modes: biometric authentication (fingerprint, voice, facial recognition), password authentication, and combination modes. This universal system allows the device to adapt to different security requirements and user preferences, managing complexity through modular design where biometric components can be activated or deactivated based on needs, thereby improving reliability without permanently increasing device complexity.
Solution Approach 2:
The patent segments the authentication system into independent modules: biometric data capture module, biometric data processing module, password authentication module, and decision-making module. This segmentation allows each component to be developed, tested, and maintained independently, reducing overall system complexity while maintaining high reliability through specialized functionality in each segment.
3Reliability
If multiple authentication factors are required, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements a dynamic authentication system that adjusts the number and type of authentication factors required based on real-time risk assessment. The system evaluates contextual information (device location, time of day, user behavior patterns, request sensitivity) and dynamically determines whether to require single-factor or multi-factor authentication. This dynamic approach maintains high reliability for risky operations while preserving ease of operation for routine tasks, thereby resolving the contradiction between authentication strength and user burden.

AI summary
Techniques are disclosed relating to contextual authentication across different applications based on user communications. In some embodiments, a user is preauthenticated to certain actions on a second application based on the user's communication via a first application. The user's communication via a first application provides contextual information that may be used to preauthenticate a request to perform an action on the second application. Contextual information may include the user's communication itself, communications characteristics that are determined from the user's communications, or both. In some embodiments, the degree of preauthentication progressively increases or decreases with the degree of use on the first application; that is, the user is preauthenticated to greater or fewer portions of an authentication procedure, to perform greater or fewer actions, or to perform actions more or less critical to security, as additional information regarding the user's communication on the first application becomes available. In some embodiments, preauthentication may be revoked as additional contextual information becomes available on the first application.
