Abstract: In the Iris based biometric recognition systems, iris needs to be segmented before comparison and hence iris segmentation is a crucial process in iris based biometric recognition systems. Existing techniques are unable to segment iris due to occlusions and require complex and time consuming algorithms to remove these occlusions. Other deep learning based solutions require precise annotations of the iris regions along with eyelids and eyelashes. The present disclosure initially generates polygons on the iris and pupil area using a pre-trained detection model. Internally covered vertices and externally exposed vertices of the generated polygons are computed to construct curvature of the iris region. A pupil region is generated by filtering the plurality of vertices lying inside pupil circle region from the plurality of externally exposed vertices. Further, a segmented iris image is generated by removing the pupil region from the input image based on the curvature of the iris region.

Abstract: This disclosure relates generally to method and system for secure IoT device onboarding using a blockchain network. Internet of Things (IoT) device onboarding is a challenging problem as it needs to be securely connected to its actual final owner, with minimal manual intervention. Onboarding provides provisioning the IoT devices with credentials for accessing a network resource and assigning appropriate permissions. The present disclosure establishes a mutual authentication between at least one IoT device from the one or more IoT devices and a TIMS. Further, based on the verified authentication the TIMS enables the device to identify its current owner using a blockchain network. Further, the IoT device authenticating parameter is computed for authentication of the TIMS with at least one IoT device from the one or more IoT devices.
