External Rendering Device Secures Content Against Malware
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Malware, such as screen scrapers and keyloggers, can intercept sensitive information on user computing devices by rendering and capturing confidential data displayed on websites or entered by users, posing a risk of unauthorized access and data theft.
Innovation Solution
Implementing a system where a computing device generates a graphical representation of content and sends it to an external rendering device, which analyzes the representation to determine display characteristics and a network address, retrieves the actual content, and renders it outside the traditional graphic pipeline, preventing malware on the computing device from accessing secured content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is rendered on the computing device using traditional graphic pipeline, then the content can be displayed on the display device, but malware on the computing device can intercept and capture the sensitive information
Solution Approach 1:
An external rendering device is introduced as an intermediary between the computing device and display device. The computing device sends rendering instructions to the external rendering device, which then renders the content and displays it on the display device. This intermediary approach prevents malware on the computing device from intercepting sensitive information while maintaining the rendering functionality.
2Reliability
If content is rendered externally, then unauthorized access is prevented, but additional devices and processing steps are required
Solution Approach 1:
The rendering system is segmented into separate functional components: the computing device generates rendering instructions, the external rendering device performs the actual rendering, and the display device displays the output. This segmentation isolates the sensitive rendering process from potential malware on the computing device while maintaining system functionality.
3Manufacturing precision
If graphical representation is analyzed to determine display characteristics, then precise rendering control is achieved, but processing time and computational resources increase
Solution Approach 1:
The computing device prepares rendering instructions in advance that include all necessary display characteristics and parameters. The external rendering device receives these pre-prepared instructions and can immediately begin rendering without requiring extensive analysis time, thus reducing processing delays while maintaining rendering precision.

AI summary
Methods, systems, apparatuses, and computer program products are provided herein for rendering secured content. For instance, a computing device may be utilized to view content that is to be displayed via a display device coupled thereto. However, rather than rendering the content, the computing device generates and/or provides a graphical representation of the content to a rendering device coupled between the computing device and the display device. The rendering device analyzes the graphical representation to determine characteristics of the graphical representation, characteristics of a display region of an application window in which the content is to be rendered, and a network address at which the actual content is located. The rendering device retrieves the content using the network address and renders the retrieved content over the display region of the application window in accordance with the characteristics determined for the graphical representation and the display region of the application window.
