Client-Side Ad Creative Signature Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solutions are inadequate in detecting anomalous advertisements early and efficiently, as they often fail to meet targeting constraints, have impractically high scanning frequencies for low-frequency malware probes, and struggle to scan the large number of ad creatives served through ad networks, leading to delayed detection and potential malware delivery.
Innovation Solution
Implementing client-side functionality to capture and analyze ad creative information, generating signatures using cryptographic hash functions, and transmitting these to an ad network for comparison against stored data to identify anomalous advertisements, thereby enabling earlier and more effective detection of malware-related risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If server-side scanning is used to detect anomalous advertisements, then detection capability is provided, but scanning frequency must be impractically high for low-frequency malware probes, leading to excessive resource consumption
Solution Approach 1:
The patent implements client-side functionality that enables user devices to autonomously capture ad creative information and generate signatures without requiring intensive server-side scanning. Each device performs local detection operations, eliminating the need for frequent server-side scans and reducing overall system resource consumption while maintaining detection reliability.
2Reliability
If server-side scanning is used to detect anomalous advertisements, then detection capability is provided, but latency is high and false measurements occur
Solution Approach 1:
The patent performs ad creative information capture and signature generation on the client side before the advertisement is fully rendered or interacted with. This preliminary detection action occurs at the source, eliminating the time delay associated with server-side scanning and reducing detection latency while maintaining accurate detection capability.
3Reliability
If conventional scanning methods are used, then detection is performed, but double counting of impressions occurs, reducing accuracy
Solution Approach 1:
The patent divides the detection function into client-side and server-side components. The client-side functionality captures ad creative information and generates signatures locally, while the server receives and compares these signatures. This segmentation ensures that each impression is counted and detected exactly once at the source, eliminating double counting and improving measurement precision.

AI summary
Systems, methods, and computer-readable media are disclosed for detecting anomalous advertising content and taking or directing one or more actions to be taken to mitigate risk associated with anomalous advertising content. The anomalous advertising content indicates a deviation from an expected state of the advertising content. Various measures may be taken to determine whether the anomalous advertising content is reflective of malware.
