Handheld Biometric Capture Device for Portable Iris Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric identification systems, particularly those using iris recognition, are limited by their fixed and complex nature, making them unsuitable for portable or handheld applications, which hinders their use in real-time scenarios due to difficulties in capturing high-quality, focused images.
Innovation Solution
A handheld biometric processing and communication system that utilizes a commercially available mobile device, such as an iPhone or Android, in conjunction with a dedicated biometric processing device, to capture and transmit digital images of biometric attributes like fingerprints or irises to a back-end server for encoding and comparison, leveraging existing wireless communication networks for secure and efficient processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If fixed, hard-wired iris recognition systems are used, then processing power and speed are improved, but portability and ease of operation deteriorate
Solution Approach 1:
The system divides processing tasks between the handheld device (image capture and transmission) and remote servers (encoding and comparison), allowing the handheld device to remain portable while leveraging remote processing power for complex operations
Solution Approach 2:
A handheld biometric capture device serves as an intermediary between the user and remote identification servers, capturing biometric images locally and transmitting them for processing, thus combining portability with powerful remote processing capabilities
2Measurement precision
If stationary optical platforms are used, then image capture quality is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the complex encoding and comparison functions from the handheld device and places them on remote servers, leaving the handheld device with only capture and transmission functions, thus reducing its complexity while maintaining image quality
Solution Approach 2:
The handheld device uses a standard digital camera capable of multiple functions (photography, video, etc.) rather than a specialized optical platform, reducing complexity while maintaining sufficient image capture quality for biometric identification
3Reliability
If fixed iris recognition systems are deployed, then identification accuracy is improved, but real-time application capability deteriorates
Solution Approach 1:
The system performs image capture and transmission immediately in real-time, while encoding and comparison are initiated concurrently on remote servers, allowing the process to proceed without waiting for sequential completion of each step

AI summary
A mobile, wireless biometric identification system includes a biometric capture device which enables a smartphone, using a commercially established wireless communication networks, to capture a digital image of a human biometric (iris, fingerprint, etc.) for transmission to a central server. The biometric capture device captures a high quality image for encoding, while the overall system leverages the existing cellular communication network. The server receives the image, encodes the image to a biometric template, and compares the encoded template to reference templates stored in a database to identify the individual. Identification data is transmitted back to the smartphone device and displayed. Additionally, the device includes at least one other data capture device which can read, capture and transmit at least one of a variety of other data types from a variety of different government issued credentials, such as passports, driver's licenses, green cards, visas and/or other identity cards.
