    摘要： A system retrains a natural language understanding (NLU) model by regularly analyzing electronic documents including web publications such as online newspapers, blogs, social media posts, etc. to understand how word and phrase usage is evolving. Generally, the system determines the frequency of words and phrases in the electronic documents and updates an NLU dictionary depending on whether certain words or phrases are being used more frequently or less frequently. This dictionary is then used to retrain the NLU model, which is then applied to predict the meaning of text or speech communicated by a people group. By analyzing electronic documents such as web publications, the system is able to stay up-to-date on the vocabulary of the people group and make correct predictions as the vocabulary changes (e.g., due to natural disaster or pandemic). In this manner, the safety and health of the people is improved.

    摘要： Systems, computer program products, and methods are described herein for implicit item embedding within a simulated electronic environment. In various embodiments, the invention includes utilizing a hybrid recommendation engine, the invention suggests product placements based on user data and preferences of a specific user. During the initial warm-up period, either user-based or product-based collaborative filtering is applied to assign the user to a collaborative user group until more information about the user becomes available. The hybrid recommendation engine is enhanced through a collaborative clustering component, which involves assigning the user to the collaborative user group via user-based collaborative filtering based on their similar user characteristics, product interests, or product preferences. The invention dynamically alters digital content streamed to the user's device. An implicit product placement module integrates recommended products within the entertainment content, providing a seamless and personalized experience for the user.

    摘要： Aspects of the disclosure relate to message validation. A computing platform may receive a message, sent by a first device and directed to a second device, from an electronic messaging server. The computing platform may verify, based on message sender details, an identity of a sender of the message. The computing platform may generate, after verifying the identity of the sender of the message, an authentication token for the message, and may inject the authentication token into the message. The computing platform may route, to the electronic messaging server and after injecting the authentication token into the message, the message. The computing platform may receive a request to validate the message, which may include the authentication token and details of the message. The computing platform may identify, using the authentication token and the details of the message, that the message is authenticated.

    摘要： Real-time adjustment of the volume of passcode entry authentication attempts is performed based on systematic determinations of the likelihood that the passcode entrant is the rightful holder/user of the active passcode. Specifically, after an entered passcode has been determined to be incorrect, a determination is made as to the likelihood that the passcode entrant is the rightful holder of the active passcode and, based on such a determination, the number of authentication attempts afforded the passcode entrant is either increased, decreased or exhausted. Systematic determination of the likelihood that the passcode entrant is the rightful holder/user of the active passcode is accomplished by applying predetermined mismatched passcode rules and comparing machine learning (ML)-based user authentication behavior patterns to characteristics of the current authentication attempt.

    摘要： A system is provided for containerization-based countermeasures to cybersecurity vulnerabilities. In particular, the system may generate one or more containers (e.g., virtual environments), where each container may be configured to execute one or more tasks. At least a portion of the containers may be decoy containers that may be executing one or more decoy tasks. The system may then use a randomized process to change which containers are decoy and/or which tasks or jobs are executed within each container. Each container may be associated with a cryptographic key such that each container may be hashed by the system and compared against a reference hash associated with the container. If the hash has changed, the system may determine that the container has been modified and subsequently implement one or more intelligent remediation processes.

    摘要： A system is provided for validation and authentication of resources in a virtual environment. In particular, the system may embed a digital source identifier into a digital or virtual resource within the virtual environment. For instance, in some embodiments, the digital source identifier may be an image file that may be stored within one or more pre-defined areas or regions of the virtual resource, where the image file serves as an indicator of authenticity and validity of the virtual resource. Accordingly, the system may comprise a scanner that may be configured to scan the one or more pre-defined areas or regions to detect the presence of the digital source identifier. If the digital source identifier is found, the system may determine that the virtual resource has been validated and authenticated.
