  • Publication number: 20250150287
    Abstract: Systems, methods, and computer program products: determine, a network delay equal to a server system time stamp associated with a system time of a server at which a login request from a user device is received by the server minus a first server system time stamp received in the login request; initiate a session timer from a time equal to the first user system time stamp plus the network delay; transmit, to the user device, an authentication cookie or access token; receive, from the user device, a further request including the authentication cookie or access token and a user system time stamp associated with the system time of the user device; validate, the authentication cookie or access token; determine, a time difference between the user system time stamp plus the network delay and the session timer; and authorize or deny, based on the time difference, the further request.

  • Publication number: 20250112922
    Abstract: Provided are computer-implemented methods that may include receiving, via a communication network, a request to perform an online action from a user device; retrieving data associated with a number of times the user device performed the online action within at least one time interval; determining whether a dataset associated with a number of times a plurality of user devices have performed the online action within the at least one time interval is normally distributed; and determining a standard deviation associated with the number of times the user device performed the online action within the at least one time interval in response to determining that the dataset is normally distributed, and performing a control operation associated with the request to conduct the online action based on a threshold of standard deviation. Systems and computer program products are also provided.

  • Patent number: 12081979
    Abstract: Authentication of an Internet-of-Things (IoT) device comprises receiving, by a proxy application executing on a mobile device during a registration process, a device identifier associated with the IoT device. The proxy application transmits the device identifier to a router of the wireless network. The proxy application receives the device identifier from the router in response to the router receiving an authorization request with no network password from the IoT device for access to the wireless network, where the router forwards the device identifier to the proxy application. The proxy application prompts the user of the mobile device to enter the password, and transmits the entered network password to the router, such that the router validates the password and grants the IoT device access to the wireless network, the IoT device transmits the IoT device identifier to the router for subsequent network connection without a need for the mobile device.
