Secureye Biometric Sdk

Instead of storing the actual fingerprint image (which is insecure and takes up 50KB+), the SDK extracts minutiae points—the ridge endings, bifurcations, and dots on a finger. A Secureye template is usually only 256 to 512 bytes. This allows for lightning-fast searches across databases of millions of users.

Security is paramount. The SDK does not store raw fingerprint images (which can be reconstructed). Instead, it converts biometric data into a mathematical template (hash). These templates can be encrypted using AES-256 or stored in a proprietary secure format. secureye biometric sdk

Let’s look at a pseudo-code example of how easy the Secureye Biometric SDK is to use (C# .NET). Instead of storing the actual fingerprint image (which

// Initialize the SDK
SecuGen.SGFCreator sgfCreator = new SecuGen.SGFCreator();
SecuGen.ISGFingerEx sgfFinger = (SecuGen.ISGFingerEx)sgfCreator.CreateObject("SGFingerEx");
// Open the Secureye device on USB Port 1
sgfFinger.Open(0); Security is paramount
// Capture the fingerprint
if (sgfFinger.GetImageEx(5000, quality) == true) // 5 second timeout
// Extract the template (The magic happens here)
byte[] template = sgfFinger.GetTemplateEx();
// Store this byte array in your SQL database
SaveToDatabase(userID, template);
// Verification later
byte[] storedTemplate = LoadFromDatabase(userID);
sgfFinger.Verify(storedTemplate, ref matched);
if (matched) Console.WriteLine("Access Granted");
