Split Biometric Data Processing for Peripheral Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric data processing in existing systems is inefficient due to higher latency and lower bandwidth associated with external peripheral interconnects, which can lead to suboptimal authentication performance and security vulnerabilities.
Innovation Solution
The processing of biometric data is split between a processor on a peripheral device and a host device, with pre-processing and pre-validation performed on the peripheral device before transmission to the host, using a secure circuit to ensure data quality and security, and encryption to protect the data during transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If biometric data processing is performed entirely on the host device, then authentication security is maintained, but processing latency increases and bandwidth consumption increases
Solution Approach 1:
The patent divides biometric data processing into two segments: pre-processing and pre-validation performed on the peripheral device, and final validation performed on the host device. This segmentation reduces the amount of data transmitted over the interconnect and minimizes host processor involvement, thereby reducing latency and bandwidth consumption while maintaining security through the split architecture.
Solution Approach 2:
The patent implements pre-processing and pre-validation of biometric data on the peripheral device before transmission to the host. This preliminary action filters out low-quality data and prepares the biometric data in advance, reducing the processing burden on the host device and accelerating the overall authentication process.
2Adaptability or versatility
If biometric data is transmitted over external peripheral interconnects, then peripheral device access is enabled, but data security vulnerabilities increase and transmission bandwidth is limited
Solution Approach 1:
The patent performs pre-validation of biometric data quality on the peripheral device before transmission. This preliminary quality assessment ensures that only high-quality, valid biometric data is transmitted over the external interconnect, reducing the risk of transmitting corrupted or fraudulent data and improving overall system reliability.
Solution Approach 2:
The patent introduces an intermediary processing layer on the peripheral device that prepares and validates biometric data before it reaches the host device. This intermediary acts as a buffer and filter, enhancing security by preventing direct exposure of raw biometric data over the external interconnect while maintaining peripheral device compatibility.
3Productivity
If all biometric data processing is performed on the host processor, then processing accuracy is maintained, but host processor load increases and authentication speed decreases
Solution Approach 1:
The patent segments the validation process into pre-validation on the peripheral device and final validation on the host device. The pre-validation stage performs initial quality checks and filtering, while the host device performs the final authoritative validation. This segmentation accelerates authentication by eliminating unnecessary data transmission and processing steps while preserving accuracy through the final host-based validation.
Solution Approach 2:
The patent implements partial processing on the peripheral device (pre-processing and pre-validation) rather than requiring complete processing on the host. This partial action on the peripheral side filters out invalid data and prepares valid data for faster host processing, improving authentication speed while the host performs the essential validation to maintain accuracy.
Data Source
AI summary
In an embodiment, processing of biometric data is split between a processor on a peripheral device and a processor of a host device that is coupled with the peripheral device. One embodiment provides a method comprising, on a peripheral device coupled with a host device, capturing biometric data using a biometric sensor of a peripheral device and pre-processing the captured biometric data using a processor of the peripheral device. The processor of the peripheral device is separate from a processor of the host device and resides within a chassis or housing of the peripheral device. The method additionally includes pre-validating the pre-processed biometric data to determine whether the pre-processed biometric data meets a minimum quality threshold and transmitting the pre-validated biometric data to the host device for validation.
