  • Publication number: 20250328895
    Abstract: A method for determining whether a secure transaction between a user computing device and a server, connected via a network, is controlled remotely via a remote access tool. The method includes, during the secure transaction, actively perturbing and/or probing the network to change the conditions in the network. During perturbing of the network, data relating to user interactions with a user interface associated with the user computing device is collected and compared to reference data relating to user interactions carried out prior to the secure transaction or prior to perturbing of the network. Based on the comparison, a probability that the secure transaction is carried out via a remote access tool is computed and is compared to a predefined threshold. If the threshold is exceeded, the secure transaction is terminated.

  • Publication number: 20250310349
    Abstract: The systems and methods are provided that can enable the detection of certain modes of online interactions carried out by a user's computing device, for example, when an online app or webpage of an enterprise is accessed by the user's computing device. Certain exemplary implementations may utilize collector code that resides in the app or webpage opened by users accessing the enterprise service to measure and collect timing data to detect whether the user's computing device or associated browsing session is subjected to modes of manipulation such as the user browser's privacy mode being engaged, malware interacting with the browsing session, and/or some type of aggregator interacting with the browsing session. Such modes of manipulation can impact the utility and accuracy of certain forms of behavioral biometric algorithms, particularly those that utilize users' typing, timing, keystroke dwell, etc.

  • Patent number: 12197722
    Abstract: Systems and methods are provided for detecting when a user uses one or both hands to interact with a device having a physical or virtual keyboard. In one implementation, one-handed typing is determined by analyzing intragroup and intergroup keyflight timing distributions between different groups of clustered keys, each cluster having distinctly different proximal properties. A statistical measure made between the intragroup and intergroup keyflight timing distributions may be performed to determine one-handed or two-handed typing input, which may be used to enhance a user experience by adapting a viewing or input element to an appropriate hand setting. In another implementation, the detection may be used as input to determine a likelihood of suspected coaching fraud for online banking applications. In yet another implementation, the detection of one-handed typing is used as an input to bot detection algorithms to reduce false positives from other modalities.
