Solution Overview

Problem

Malicious programs can clandestinely activate the camera on smart terminals, leading to unauthorized image capture and privacy disclosure, as existing solutions do not effectively prevent such candid photographing.

Innovation Solution

A photographing processing method and terminal device that acquire and evaluate photographing instructions based on preset conditions, such as the enabling of a preview function and preview window size, to determine if a photographing operation is legitimate, and if not, terminate the operation or replace image data to prevent unauthorized image capture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the photographing function is enabled in the background without user notification, then the malicious program can perform candid photographing, but user privacy is disclosed

Engineering Contradiction:
Improvephotographing operation executionVSAvoiduser privacy disclosure
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary verification by checking whether the preview function is enabled before allowing the photographing operation to execute. This preliminary action prevents malicious candid photographing by validating the legitimacy of the photographing request in advance, ensuring that only authorized photographing operations can proceed while blocking unauthorized background photographing attempts

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If the preview function is not enabled, then candid photographing can occur undetected, but legitimate photographing operations require the preview function to be visible to users

Engineering Contradiction:
Improveuser awareness of photographingVSAvoidunauthorized photographing
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system uses the preview function as a feedback mechanism to provide user awareness of photographing operations. By checking whether the preview function is enabled, the system ensures that users are notified and aware of legitimate photographing operations, while the absence of preview feedback indicates a malicious candid photographing attempt that should be blocked

Inventive Principle:
Principle #23Feedback

AI summary

Embodiments of the present invention provide a photographing processing method and a terminal device. The method includes: acquiring a photographing instruction, where the photographing instruction includes a photographing parameter required for this photographing operation; determining, according to the photographing parameter, whether this photographing operation meets a preset photographing condition; and performing anti candid photographing processing on this photographing operation if it is determined that this photographing operation does not meet the photographing condition. In technical solutions of the present invention, before photographing is performed, it is determined whether this photographing operation meets a preset photographing condition; if the condition is not met, anti candid photographing processing is performed, thereby solving a problem that a malicious program candidly performs photographing by using a terminal.
