Fingerprint SDK Overview
A fingerprint SDK is a software toolkit that allows software developers to integrate a fingerprint recognition system into a variety of applications. Commonly, a fingerprint SDK will utilize either DLL or ActiveX (COM) to interface with the integrated application. By referencing these DLL or COM objects, software developers are able to utilize the fingerprint functionality from within a desired application.
Fingerprint SDKs provide a low-level framework to communicate with the fingerprint reader, capture an image, extract the unique minutiae data from the image, and compare two sets of extracted minutiae data. However, the developer must overcome a significant learning curve in order to produce a robust, turn-key fingerprint system from even the best fingerprint sdk.
Fingerprint SDK Functions
initialize() — Initializes the fingerprint SDK API (when starting)
cleanup() — Release resources initialized by API (when finished)
openDevice() — Open a fingerprint scanner device
closeDevice() — Close fingerprint scanner device
captureImage() — Captures a fingerprint image from device
getMinutiae() — Extracts minutiae points from captured fingerprint
matchMinutiae() — Compares two minutiae records (1-to-1)
NIST Evaluation of Fingerprint SDK
NIST evaluates biometric systems according to the following operational model: 1. A template is created for each target element t in set T. The successful creation of a template is considered a successful enrollment, otherwise the is considered an enrollment failure. 2. Each image q in set Q is compared to each successfully generated template (i.e., all query elements are pair wise compared against all target elements). For each comparison, the score representing the similarity between the images is recorded. The score is assumed to be a floating-point number that represents the similarity between the images. Higher scores indicate similar biometric signatures, lower scores dissimilar ones. A predetermined null similarity score (typically zero) would be used given a system error, such as failure to enroll the target or query signature. NIST Fingerprint SDK Evaluation
Common Developer Issues of a Standard Fingerprint SDK
- What constitutes a good fingerprint scan? What constitutes a bad fingerprint scan?
- How to save extracted minutiae
- How to load the information back from the stored location
- How to encrypt/decrypt fingerprint data
- How to establish a transmit comparison requests across a network to facilitate a client/server topology
- How to associate multiple prints for a single individual
- How to convert a 1:1 (verificiation) comparison functionality and build it into a 1:N (identification) solution
- Reliability of the comparisons against larger population sizes
