Video Signature Authentication for Secure Resource Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication mechanisms, such as username/password combinations, are vulnerable to theft and spoofing, and biometric scanning is not widely available, necessitating a more robust authentication method that leverages the video capture capabilities of computing devices.
Innovation Solution
The method generates a video signature by analyzing user-created video segments with visual and audio elements, calculating a total score, and using this score for authentication by comparing subsequent video segments to grant access to secure resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication mechanisms like username/password are used, then ease of operation is maintained, but security reliability deteriorates due to susceptibility to theft and spoofing
Solution Approach 1:
The patent creates a video signature that copies and encodes multiple unique characteristics of the user's video segment (visual elements, audio elements, temporal patterns) into an authentication credential. This copied signature can be stored and verified without requiring the user to remember complex information, maintaining ease of operation while significantly improving security against theft and spoofing compared to traditional passwords
Solution Approach 2:
The authentication system combines multiple different types of data elements (visual characteristics, audio characteristics, temporal patterns) into a composite video signature. This composite approach creates a multifaceted authentication credential that is much harder to spoof than single-factor authentication, improving reliability while the automated analysis keeps the user experience simple
2Reliability
If biometric scanning is implemented, then authentication reliability improves, but device complexity increases due to specialized hardware requirements
Solution Approach 1:
The patent makes the camera serve multiple functions: it captures video for authentication purposes in addition to its standard photo/video recording function. By analyzing existing video segments captured by the camera, the system creates authentication credentials without requiring separate biometric hardware, thus improving security reliability while avoiding increased device complexity
Solution Approach 2:
The system uses the user's own video content, captured by their device's camera, to generate the authentication signature. The computing device itself performs the analysis and signature generation without external specialized equipment, allowing the device to authenticate itself using resources already available, thereby improving security without adding hardware complexity
3Reliability
If video segments with multiple visual and audio elements are analyzed, then authentication reliability improves through unique identification, but computational complexity increases
Solution Approach 1:
The system extracts only the essential authentication-relevant features from the video segment (specific visual elements, audio elements, and temporal patterns) rather than processing the entire video data. This extraction of key characteristics into a condensed signature reduces the computational burden while maintaining the unique identification capability that provides high authentication reliability
Solution Approach 2:
The authentication process is divided into distinct segments: initial video capture, analysis of visual elements, analysis of audio elements, signature generation, and verification. This segmentation allows the complex task of video analysis to be broken into manageable steps that can be processed efficiently, reducing overall computational complexity while maintaining security reliability

AI summary
Methods and apparatuses, including computer program products, are described for authentication using a video signature. A computing device receives a request to access a secure resource, and the request includes a first video segment comprising a plurality of visual and audio elements. The computing device analyzes one or more of the plurality of visual and audio elements in the first video segment to determine a value associated with each of the one or more analyzed elements. The computing device calculates a total score for the first video segment based upon the value associated with each of the one or more analyzed elements. The computing device compares the total score for the first video segment to a score associated with a second video segment associated with the computing device. The computing device determines whether access to the secure resource is permitted based upon the comparison step.
