Multimodal biometric app developer Hoyos Labs has filed a legal complaint against eye vein recognition firm EyeVerify, claiming that it has misled consumers.In a case launched on 4 September in New York Southern District Court, Hoyos said tests it had conducted on EyeVerify's Eyeprint ID solution undermined the assertion that it can identify unique patterns of blood vessels. In an interview with Planet Biometrics, EyeVerify dismissed the allegations as false.Hoyos' complaint stated: “The defendant has specifically used the false statement about its capture and use of blood vessels in the eye-whites in commercial advertising to sell its Eyeprint product to banks and corporations in this judicial district, including, but not limited to, the same banks and corporations that comprise plaintiff's customer base.”Hoyos, which has developed the 1U biometric identity application, seeks an injunction that would prevent EyeVerify from advertising that Eyeprint ID uses blood vessels, amid other punitive actions.Toby Rush, EyeVerify's CEO, told Planet Biometrics: “We are disappointed and surprised to see such a frivolous and clearly false claim against EyeVerify. For Hoyos Labs to suggest that our software does not use eye veins is factually incorrect. Use of eye veins as a biometric modality has always been part of our technology from day one.”Rush supplied the image shown below, which he said contained examples of how the firm's “machine vision techniques enhance images to reveal vein based points that are used for feature extraction”.Hoyos Lab's complaint stated that its tests had found that Eyeprint ID actually scans a “periocular” area surrounding the eye, rather than eye veins.Responding to these allegations, Rush added: “Regarding additional micro features found in the eye, we have found them to increase the robustness of our system, but that is a supplement to eye vein based techniques.”
