Remote Recording Proofing With Dynamic ID Presentation Challenges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote identity verification systems face challenges in ensuring the timeliness and originality of recordings, particularly in preventing digital forgery and replay attacks, as users can manipulate recordings using their own devices, making it difficult to verify the authenticity and freshness of the presented identification documents.
Innovation Solution
A method and system that challenges users to present a physical object, such as an identification document, in a unique or quasi-unique spatially varied sequence of presentations, using a camera and display to ensure timeliness and originality by randomly or quasi-randomly selecting coordinates for the object's placement, combined with active watermarking and object recognition to validate the authenticity and freshness of the recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users use their own devices to present identification documents in remote verification, then accessibility and convenience are improved, but security against digital forgery and replay attacks deteriorates
Solution Approach 1:
The system dynamically generates a time-varying challenge sequence that changes during the recording process. The challenge includes moving a target object through specific spatial positions and orientations that are randomly determined, making it impossible to use pre-recorded videos or static images. This dynamic approach maintains user convenience while preventing replay attacks and digital forgery.
Solution Approach 2:
The verification process employs periodic challenges where the system requests the user to present the identification document at specific time intervals and spatial positions. The challenge sequence is divided into multiple periodic steps, each requiring the document to be displayed in a specific orientation and location within the camera view, ensuring real-time verification and preventing manipulation.
2Adaptability or versatility
If traditional optical verification methods are used, then compatibility with various ID documents is improved, but verification of recording timeliness and originality deteriorates
Solution Approach 1:
The verification process is segmented into multiple independent challenge steps, each verifying a specific aspect of the recording's authenticity. The system divides the verification into spatial positioning, temporal sequencing, and optical特征 recognition components. This segmentation allows the system to maintain broad ID document compatibility while rigorously verifying timeliness and originality through multiple independent checks.
Solution Approach 2:
The system changes multiple parameters during the verification process, including the spatial coordinates where the ID document should be displayed, the orientation angles, the time intervals between presentations, and the lighting conditions. These parameter changes ensure that each verification instance is unique, preventing replay attacks while maintaining compatibility with various ID document types through optical recognition.
3Ease of operation
If simple photo verification is used, then user experience is improved, but trust in established identity deteriorates
Solution Approach 1:
The system provides real-time feedback to the user during the verification process, guiding them through the challenge sequence. The display shows the current challenge requirements, the captured images, and verification status. This feedback mechanism maintains a simple user experience while implementing complex verification logic that establishes high trust in the identity verification through multiple security checks.

AI summary
The present invention relates to a method and a system (10) for automatic proofing of a remote recording, wherein a recording is captured using a camera (22) of a recording device (20) having a display (24) configured to display a video stream generated by the camera (22) while the recording is being captured from the video stream generated by the camera (22), wherein, during the recording, a user is challenged to show a physical object (40), in particular an identification document, to the camera (22). For further verifying timeliness and/or originality of the recording, the user is challenged to present the physical object (40) to the camera (22) of the recording device (20) in a unique or quasi-unique spatially varied sequence of presentations with two or more steps, wherein a determination of timeliness and/or originality of the recording is carried out by means of a validation unit (12) having access to the recording and includes an automatic check whether the physical object (40) is present in the recording in accordance with the steps of the spatially varied sequence of presentations.
