Abstract: A computing device may access visually rich documents comprising an image and metadata. A graph, based on the image or metadata, can be generated for a visually rich document. The graph's nodes can correspond to words from the visually rich document. Features for nodes can be determined by the device. The device may generate model labeled graphs by assigning a pseudo-label to nodes using a pretrained model. The device may generate a plurality of graph labeled graphs by assigning a pseudo-label to nodes by matching a first node from a first graph to at least a second node from a second graph. The device may generate a plurality of updated graphs by cross referencing labels from the model labeled graphs and the graph labeled graphs. Until a change in labels is below a threshold, a model can be trained to perform key-value extraction using the updated graphs.

Abstract: A computing device may receive a set of user documents. Data may be extracted from the documents to generate a first graph data structure with one or more initial graphs containing key-value pairs. A model may be trained on the first graph data structure to classify the pairs. Until a set of evaluation metrics for the model exceeds a set of deployment thresholds: generating, a set of evaluation metrics may be generated for the model. The set of evaluation metrics may be compared to the set of deployment thresholds. In response to a determination that the set of evaluation metrics are below the set of deployment thresholds: one or more new graphs may be generated from the one or more initial graphs in the first graph data structure to produce a second graph data structure. The first and second graph can be used to train the model.

Abstract: An example method facilitates enabling Key Encryption Key (KEK) rotation for a running multi-tenant system without requiring system downtime or interruption. The example method facilitates decrypting a set of one or more DEKs using a preexisting KEK; using a new KEK to re-encode the DEKs using the new KEK, all while simultaneously enabling servicing of tenant requests. This is enabled in part, by strategic caching of tenant DEKs in a secure local memory, wherein the cached tenant DEKs are maintained in the clear and are readily accessible to running processes that are using the DEKs to decrypt and access tenant data, irrespective of the state of a background process used to implement the KEK rotation to the new KEK.

Abstract: Techniques are provided to manage security artifacts. Specifically, a security management system is disclosed for implementing security artifact archives to manage security artifacts. A security artifact archive may include information for managing one or more security artifacts that can be referenced or included in the security artifact archive. The security management system can create, edit, read, send, and perform other management operations for security artifact archives. Objects can be bundled in an object-specific security artifact archive. Security artifact archives may be named, versioned, tagged and/or labeled for identification. Security artifact archives may be transmitted to a destination (e.g., a service provider or a client system) that provides access to an object whose access is dependent on security artifacts. The destination may can manage access to the object using a security artifact archive that includes relevant and current security artifacts for the object.
