Multi-modal biometrics firm Hoyos Labs has revealed plans to add liveness detection to its 4F mobile authentication solution.The firm's biometric app uses a smartphone's rear camera and LED flash light, without any additional hardware, to capture a person's four fingerprints.”The main feature that we're currently working on is Liveness,” the company said in an update to users.”This will provide additional security against spoofing attacks, helping to ensure that, if someone steals your phone, they can't use a mold or photograph of your fingers to authentication on the app. While 4F is already more secure than traditional fingerprint scanning, as it uses four fingers simultaneously, adding Liveness will provide significantly more safety for the user with no loss of convenience”.In the update, Hoyos also said its team is working on a Prototype App for Android devices.In a statement last year, the company said: “”4F was invented to address the difficulty of capturing biometrics, like facial recognition, which can fail with adverse lighting conditions. 4F works in any environment, because it uses the phone's flash as its light source with no external hardware required”.
