Abstract: Disclosed herein are embodiments of systems, methods, and products comprising a data power server for secure storage and retrieval of trade data. The server receives a request from a user to review or confirm one or more trade documents via a webserver. The server communicates with a connector grid server to retrieve the user's accessible documents. The connector grid server determines the electronic file IDs that are accessible to the user based on the accessibility policy. The server instructs a digital library server to download the electronic files containing the requested trade data. The digital library server retrieves and downloads the electronic files based on the file IDs. The webserver renders a GUI displaying the electronic files on an electronic client device operated by the user. Upon receiving the confirmation response from the user, the server instructs the digital library server to update the trade status.

A computing device may, in response to detecting a user within view of an image capture device of a client device, perform a first type of text recognition on a first region of digital content and a second type of text recognition on a second region of the digital content, where the first type of text recognition is determined based on a first type of content items contained in the first region and the second type of text recognition is determined based on a second type of content items contained in the second region. Based at least in part on rules corresponding to the user, the computing device may determine content items within the digital content to be concealed, and may modify the digital content to conceal the content items.

Abstract: In some implementations, a method may involve determining first feature vectors for a plurality of data items accessed by a user of one or more client devices, the first feature vectors representing first contextual data about the one or more client devices at times that respective data items of the plurality of data items were accessed, the plurality of data items including a first data item. A predictive model, configured to classify input feature vectors into context types, may be used to determine that the first feature vector for the first data item is classified as a first context type. A second feature vector representing second contextual data about a first client device operated by the user may be determined and the predictive model may be used to determined that the second feature vector is classified as the first context type.
