Abstract: Aspects of the present disclosure are directed to methods and systems for applying electronic signatures to an electronically stored document wherein the electronic signatures are associated with a specific revision of that electronically stored document (revision specific electronic signatures).

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer-readable storage medium, and including a method are provided where the method includes receiving information from an image processing source that includes one or more images of a view area associated with a device, wherein the view area is an area located in front of a display screen associated with the device, wherein the view area enables one or more entities to view the display screen; determining one or more entities located within the view area based at least in part on the one or more images of the view area associated with the device; validating the one or more entities located within the view area; and when an entity within the view area is not validated, producing a security response.

Abstract: Aspects and implementations of the present disclosure are directed to systems and methods of selecting content for presentation to a viewing user. In general, in some implementations, a data processing system identifies a topic for a document requested by a user, determines a confidence score for a correlation between the topic and the document, determines a sentiment score for a sentiment towards the topic, and determines, for a candidate content item, a predicted acceptance score based on the confidence score, the sentiment score, and acceptance history data for the candidate content item. The data processing system selects a candidate content item for presentation to the user based, at least in part, on the predicted acceptance score.
