Abstract: A method is disclosed and includes receiving a token request message comprising a real credential or a reference to the real credential, a unique value, and action data from a token requestor, and obtaining a token. The method also includes transmitting the token to the token requestor, and providing the unique value and the action data to a data matching computer. The data matching computer stores the unique value and the action data. The data matching computer subsequently receives a message from a data processing computer comprising the unique value, determines that the received unique value matches the stored unique value, and provides the action data to the data processing computer or performs an action with respect to the action data.

Abstract: Techniques used by the state of the art alarm prediction systems rely mostly on LSTM, which have technical limitation in predicting a sequence with long durations. Embodiments of the present disclosure provide a method and system for long duration alarm sequence predictions from past alarm sequence using a Bi-LSTM and operator sequence recommendations thereof. The BiLSTM with an encoder decoder technique uses true output sequence as input to decoder at each time step during training. This allows the BiLSTM to learn dependencies among input and output sequence effectively. The operator sequence recommended is identified based on closeness of the predicted future output alarm sequence with one among the unique alarm sequences in a mapping table. The alarm sequence closeness is computed using a Matching Sequence Score (MSS) disclosed by the method, since known sequence evaluation metrics such as Blue Score has limitations to be directly applied in alarm sequence evaluation.

Abstract: Systems and methods for securing data transmissions using distance measurements are disclosed. A mobile device (such as a smart phone) and a base station can use ultra-wideband technology to determine the distance between the two devices. The distance measurements produced by the mobile device and the base station can be compared, directly or indirectly by the mobile device, the base station, and/or an access device to determine whether the mobile device is present at an access device or if the mobile device is not present at the access device (as expected during a relay attack). If the mobile device is not present at the access device, the access device can prevent or cancel an interaction based on the data transfer (e.g., opening a locked door of a secure building in response to receiving an access credential from the mobile device).

The present disclosure provide a method and system that enable hybrid architecture in an enterprise application to mitigate quantum attacks. The method of the present disclosure changes codebase of the enterprise application to enable hybrid architecture. New paths are created within the enterprise application to support execution of a new library code that enables double encryption of data being processed by the application.

Abstract: Methods and systems are described herein for updating machine learning models based on the impact of features on predictions. The system inputs, into a machine learning model, a dataset including entries and features to obtain predictions. The machine learning model is trained to generate predictions for entries based on features. The system generates, for each entry, feature impact parameters indicating a relative impact of each feature on each prediction. The system determines a feature impact threshold for assessing which features have contributed to each prediction and generates, using the feature impact parameters and the feature impact threshold, a sparsity metric for each prediction. The sparsity metric indicates which features have relative impacts that meet the feature impact threshold for the prediction. The system generates a global sparsity metric for the machine learning model and updates the machine learning model based on the global sparsity metric.

Abstract: The present disclosure provides a system for securing communication between Central Controller and signaling devices including actuator devices and signaling sensors used in railway and road traffic signaling networks. Conventional signaling systems use unsecured metal cables to communicate between the Central Controller and the signaling devices, making them vulnerable to unauthorized intrusion and mischief. In the present disclosure, two uniquely addressable communication modules, one (SCM1) securely housed with the Central Controller and another (SCM2) securely housed in an assembly also containing the signaling device and the related power switches are used to establish a transparent but standard secure digital communication protocol between them to authenticate and validate mutual communication, making them secure and safe from intrusion and undesirable manipulation.

Abstract: Systems and methods for authentication of resource objects at a public portal. In some aspects, a system, in response to receiving a resource object, requests data including: (1) a flag indicating whether a resource object associated with the resource identifier present on the resource object is under control of the user or another user and (2) a last recorded time and location associated with the resource identifier being scanned at the public portal or another public portal. The system determines that the resource object is under control of the user or another user, and responsive to that determination, determines a threshold based on time elapsed between the last recorded time and the time the resource object was received. The system, in response to determining that a distance between the public portal and the last recorded location exceeds the threshold, generates a command to escalate the resource object for further processing.

Abstract: Techniques are described for managing a transaction, such as a purchase of a vehicle or other product, using one or more blockchains. The completion of a transaction may be facilitated by providing an information portal, such as one or more application user interfaces, to enable the buyer, seller, or other parties to readily access blockchain-stored information that is relevant to the transaction. In some examples, where the product to be purchased is a vehicle (e.g., car, truck, motorcycle, boat, etc.), the blockchain-stored information may include information regarding the loan, title, insurance, driver's license or other identification verification, vehicle ownership history, inspection history, repair history, lien information, and so forth. The portal also enables a point of contact to be maintained between the buyer and a lender during the process of purchasing the product.

Abstract: Methods and systems are disclosed herein for using anomaly detection in timeseries data of user sentiment to detect incidents in computing systems and identify events within an enterprise. An anomaly detection system may receive social media messages that include a timestamp indicating when each message was published. The system may generate sentiment identifiers for the social media messages. The sentiment identifiers and timestamps associated with the social media messages may be used to generate a timeseries dataset for each type of sentiment identifier. The timeseries datasets may be input into an anomaly detection model to determine whether an anomaly has occurred. The system may retrieve textual data from the social media messages associated with the detected anomaly and may use the text to determine a computing system or event associated with the detected anomaly.

Abstract: Technology for determining an insurance fraud risk associated with a user comprises receiving, at an enterprise, a call or a chat from a user device associated with the user. Data associated with the call or the chat is analyzed to determine if at least one factor indicating fraud is present. A weighted level of possible fraud associated with the at least one factor is determined. The weighted level of possible fraud is compared to at least one weight threshold. The user is identified as an increased fraud risk based on the weighted level of possible fraud meeting or exceeding the at least one weight threshold.

Abstract: Provided is a method including receiving, by a user device, a request from an identity service to approve communicating a user proof-of-identity to a relying party. A user of the user device is prompted to request a one-time transaction identifier based on the request. Based on a first input from the user, the user device requests the one one-time transaction identifier from the identity service. In response to the request for the one-time transaction identifier, the user device receives the one-time transaction identifier from the identity server and displays the one-time transaction identifier on a first user device screen. The user inputs the one-time transaction identifier on a second user device screen and the user device communicates the one-time transaction identifier to the identity service. In response to receiving the at least one inputted one-time transaction identifier, the relying party determines whether to approve or deny a transaction.
