Biometric systems
COntactlesS Multibiometric mObile System in the wild
COSMOS

COSMOS — COntactlesS Multibiometric mObile System in the wild was a PRIN research project aimed at developing a comprehensive platform for the contactless verification and recognition of individuals in realistic, weakly controlled environments. The project responded to the need for biometric systems that are both secure and convenient, reducing the cooperation required from users and avoiding dedicated contact-based sensors. Its central concept was to exploit widely available mobile devices—such as smartphones and tablets—to acquire and process multiple biometric characteristics, adapting the acquisition and recognition strategy to the user, the available sensors and the surrounding operational conditions.
COSMOS investigated the complementary use of hard biometric traits, including 2D and 3D face, iris, ear, fingerprint and palmprint, together with behavioural and soft traits such as gait, gaze and facial age information. The different modalities were intended to be combined through adaptive fusion strategies, improving reliability when individual samples were affected by illumination variations, motion, occlusions, perspective distortion, limited resolution or other typical “in-the-wild” acquisition problems. Multi-person detection and tracking were also studied to enable screening from a distance and to maintain usable biometric observations even when subjects were partially occluded.
The associated research produced advances in several enabling technologies. These included deep-learning approaches for touchless palmprint recognition using biometric-specific, unsupervised filter learning; fusion of palmprint and inner-finger texture from a single contactless hand image; smartphone-based fingerphoto recognition; robust iris segmentation under non-ideal illumination and occlusion; and CNN-based extraction of fingerprint pores from touch-based, touchless and latent images.
Further activities explored deep models for ECG recognition, facial age estimation and explainable face-aging systems, extending the project beyond conventional image-based identifiers toward continuous and interpretable biometric authentication. Throughout the project, particular attention was given to privacy, data protection, ethical implications, user acceptance, interoperability and efficient execution on resource-constrained mobile platforms.
