Fingerprint Matching Server Transmission Delay Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fingerprint matching process in content-modification systems is inefficient and resource-intensive, particularly when identifying channels for content-presentation devices, as it requires comparing query fingerprint data with numerous reference fingerprint data sets, leading to high processing power and memory requirements.
Innovation Solution
By determining the content-transmission delay between a content-distribution system and a content-presentation device, the fingerprint-matching server selects a corresponding reference fingerprint data set and transmits it to the content-presentation device for local matching, reducing the computational burden on the server and the amount of data the device needs to process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the fingerprint-matching server compares query fingerprint data with all reference fingerprint data sets, then the channel identification accuracy is improved, but the processing time and computational resources increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-grouping reference fingerprint data sets according to transmission delay characteristics before the actual matching process. When a query arrives, the system first determines the transmission delay and then selects only the corresponding group for comparison, rather than searching through all reference data sets. This pre-organization of data enables rapid retrieval and significantly reduces processing time while maintaining identification accuracy.
2Measurement precision
If the system stores and processes all reference fingerprint data sets, then the matching accuracy is improved, but the memory requirements and device complexity increase
Solution Approach 1:
The patent applies segmentation by dividing the complete reference fingerprint data set into multiple groups based on transmission delay characteristics. Each group contains reference data for a specific transmission delay range. This segmentation allows the system to store and process only the relevant subset of data needed for a given query, reducing memory requirements and simplifying the processing logic while maintaining the ability to accurately identify channels across different transmission conditions.
3Reliability
If the system processes numerous reference fingerprint data sets, then the channel identification reliability is improved, but the energy consumption and processing power requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-organizing reference fingerprint data into transmission delay-based groups and establishing the selection logic in advance. During operation, the system simply determines the transmission delay and retrieves the corresponding pre-grouped data, avoiding the need to process all reference data sets. This approach maintains identification reliability by ensuring the correct data subset is used while dramatically reducing energy consumption through selective processing.

AI summary
In one aspect, a method includes determining a content-transmission delay between a content-distribution system and a content-presentation device. The method also includes using at least the determined content-transmission delay as a basis to select, from among a plurality of reference fingerprint data sets, a reference fingerprint data set that corresponds with the determined content-transmission delay. The method also includes transmitting to the content-presentation device, the selected reference fingerprint data set that corresponds with the determined content-transmission delay to facilitate the content-presentation device detecting a match between query fingerprint data representing content received by the content-presentation device and at least a portion of reference fingerprint data in the transmitted reference fingerprint data set.
