Hailing procedure for V2R, V2V, and V2X initial contact in 5G and 6G
Low-complexity wireless messaging procedures enable a prospective user device to select and make initial contact with a suitable base station in 5G or 6G networks.

Method of authentication
A method, of authenticating a user with a service and a server having means to enable a user to be authenticated with a service. The method having the steps of, the user requesting a session with the service on a first device. The server requesting a unique code from a host server, the host server generating the unique code, associating it with a session-identifier. The session-identifier containing information relating to the code request. The host server then sending the unique code, which does not contain the session-identifier, to the service. The server then optically presents the unique code to the user on a display of the first device. The code is then acquired by a verification application running on a second device. Optionally the first device and the second device may be the same device. The second device is previously registered with the host server. The verification application sends the unique code, and device-identifying information of the second device, to the host server. The host server, on receiving the unique code and device-identifying information, uses the unique code to retrieve the session-identifier, and uses the device-identifying information to retrieve associated user-identifying information.

Behavioral biometrics and machine learning to secure website logins
A system that uses a client's behavioral biometrics—mouse dynamics, keystrokes, and mouse click patterns—to create a Machine Learning (ML) based customized security model for each client/user to secure website log-ins.

The model collects relevant behavioral biometric data from the client when a new account is created by the client/user on a website or when the client initially logs-in to the website. The collected biometric data are used to train an ensemble of ML-based classifiers—a Multilayer Perceptron (MLP) classifier, a Support Vector Machine (SVM) classifier, and an Adaptive Boosting (AdaBoost) classifier—in the model. The trained versions of these classifiers are polled to give an optimal prediction in real-time (while the user is logging in). As a result, real-time fraud detection can be accomplished without impacting the log-in performance of the website. |
