Mobile Camera Image Evaluation for Sensitive Data Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smartphones pose a security threat by potentially leaking proprietary corporate information through camera usage, leading to either complete bans on picture-taking or camera usage, which are overly restrictive and inefficient.
Innovation Solution
Implementing image evaluation operations on mobile devices to electronically analyze camera data for sensitive information, blocking or modifying it as necessary, and reporting incidents to central servers, while allowing controlled camera usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complete ban on picture-taking by smartphones is implemented, then security against proprietary information leakage is improved, but work efficiency and user convenience deteriorate
Solution Approach 1:
The patent segments the camera functionality into controlled and uncontrolled states. Instead of a complete ban, the system selectively enables or disables camera operations based on real-time analysis of captured images. The camera is divided into monitored modes where images are automatically evaluated for sensitive content, allowing legitimate photography while blocking potentially harmful captures.
Solution Approach 2:
The patent introduces an intermediary image evaluation operation between the camera capture and the final image storage/sharing. This intermediary layer analyzes images for sensitive content (credentials, proprietary information) and acts as a gatekeeper, allowing benign images to pass through while blocking harmful ones. This mediator resolves the contradiction by enabling security without complete prohibition.
2Reliability
If camera usage is monitored and controlled, then security against information leakage is improved, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring the system with criteria for what constitutes sensitive content (credentials, proprietary information patterns). The image evaluation operations are pre-programmed with recognition algorithms and security policies, allowing the system to automatically assess and control camera usage without requiring complex real-time decision-making infrastructure.
Solution Approach 2:
The patent enables self-service by implementing automated image evaluation and control mechanisms that operate independently without requiring constant external intervention. The system self-monitors camera output, automatically detects sensitive content using embedded algorithms, and enforces security policies autonomously, reducing the need for complex external monitoring infrastructure.

AI summary
A technique provides mobile device security to a mobile device. The technique involves, in response to operation of a camera of the mobile device, receiving image data from the camera, the image data representing a visual image captured by the camera. The technique further involves performing an image evaluation operation which electronically analyzes the image data received from the camera to determine whether the image data contains sensitive information. The technique further involves, based on a result of the image evaluation operation, performing a security operation that provides security to the mobile device.
