A method includes obtaining a hierarchical document structure of a raw document. The hierarchical document structure includes a multitude of sections arranged in a hierarchy of successive document levels. A hierarchical document graph having a graph hierarchical structure corresponding to the hierarchical document structure of the raw document is constructed. A hierarchical document graph corresponding to the raw document matching a user query is retrieved. A hierarchical search is performed on the hierarchical document graph to obtain a set of relevant nodes. A set of relevant content embeddings is retrieved from the set of relevant nodes. A large language model (LLM) generates a response to the user query from the set of relevant content embeddings. The response is presented in a user application.

Hierarchical graph retrieval augmented generation with context embedding

A method, non-transitory computer readable medium and apparatus for deriving trustful metadata for an application are disclosed. For example, the method crawls online for the application, analyzes the application to determine a function of the application, and generates trustful meta-data for the application based upon the function of the application.

Method and apparatus for deriving and using trustful application metadata

Concepts and technologies are disclosed herein for multilayered deception for intrusion detection. According to various embodiments of the concepts and technologies disclosed herein, a multilayer deception system includes honey servers, honey files and folders, honey databases, and/or honey computers. A multilayer deception system controller generates honey activity between the honey entities and exposes a honey profile with contact information associated with a honey user. Contact directed at the honey user and/or activity at any of the honey entities can trigger alarms and/or indicate an attack, and can be analyzed to prevent future attacks.

Multilayered deception for intrusion detection and prevention

Concepts and technologies are disclosed herein for verifying sender information. According to various embodiments of the concepts and technologies disclosed herein, a verification service can determine, receive a request, or receive a call to verify sender information associated with data. The server computer generates and delivers a verification message to a sender device in response to determining that sender information verification is to be provided. The server computer receives a response indicating if the data was sent by the sender device. If the response indicates that the sender device did not send the data, the server computer can block delivery of the data, generate alarms or alerts, take other actions, and/or take no action. If the response indicates that the sender device sent the data, the server computer can deliver the data, provide a verification response to the recipient device, take no action, and/or take other actions.

Verification service

Techniques for controlling Session Initiation Protocol (SIP) overload between a sending entity and a receiving entity includes receiving a message at a send buffer at the sending entity and forwarding the message to a receive buffer at the receiving entity if the send buffer is empty of other messages or rejecting the message if the send buffer is not empty of other messages.

Methods and systems for controlling SIP overload

Systems for providing feedback to sending entities are provided. In some embodiments, systems for providing feedback to at least one sending entity that sends requests are provided, the systems comprising: a receiving entity comprising at least one processor that: determines a number of active sources associated with each of the at least one sending entity; determines a number of sessions that each of the at least one sending entity is able to accept based on the number of active sources determined; and provides an indication of the number of sessions to each corresponding one of the at least one sending entity.
