Abstract: Embedding of digital tokens within a digital video can occur cryptographically using a public key in some embodiments. The digital video may be altered in a variety of ways so that the video itself contains an integrated token that can represent various quantities. Audiovisual data can be altered to contain both a token and a perceptible user auditory or visual cue as to the presence of the encrypted digital token. A video with an embedded digital token may be sent to users on the Internet. A video recipient may be able to view the video and also take additional action or gain additional functionality from the digital token embedded in the video. Tokens can be embedded by altering video metadata so that the perceptible video content itself is not changed in some embodiments.

Abstract: A computer system identifies a presence of a substance in a first location of a display screen of the computing device. In response to the identifying the presence of the substance in the first location of the display screen, the computer system causes one or more elements of a content to be displayed in a second location of the display screen, wherein the one or more elements were initially displayed in the first location.

Abstract: A method for contextual pressure-sensing input, includes determining context of a document being displayed to a user by a display of a user device. The display includes a pressure-sensing input module for detecting touch inputs. The method includes determining engagement level that indicates an amount of engagement of the user with the document. The method includes determining, based on the engagement level and on the context, a pressure input requirement for the document. The pressure input requirement indicates an amount of pressure needed to verify acknowledgement of the document by the user. The method also includes determining whether a user touch input detected at the display matches the pressure input requirement.
