Examples include assembly of a portable document format file including encrypted content, unencrypted content, and/or alternative content. In an example, metadata, data block(s), and a content map are signed and stored in, or assembled into, a custom field or fields of the portable document format file. The metadata, data block(s), and content map are encrypted and assembled into a custom field or fields of the portable document format file with an encrypted key or keys. Unencrypted and/or alternative content may also be stored in the assembled portable document format file.

A roaming device obtains an identifier for a network-enabled resource as a result of interacting with the network-enabled resource. The roaming device uses the identifier to obtain a link for the network-enabled device through a cloud service. The address is used to access and use the network-enabled resource using the cloud service.

A content placement method includes electronically identifying a placeholder image in an electronic document. The placeholder defines a copy hole. The placeholder image is decoded to discern content selection data. The content selection data is processed to identify content that is inserted into the copy hole.

Content placement

A security printing method includes generating a security file having a plurality of metadata fields and an information field concatenated together in an initial sequence. A security file identification is generated from the plurality of metadata fields and the information field. The security file identification corresponds to the initial sequence and is a one-way function of the plurality of metadata fields and the information field. The method further includes selecting a custom scrambling technique based on the security file identification, and scrambling the initial sequence using the selected custom scrambling technique, thereby creating a scrambled sequence of the plurality of metadata field and the information field.

An event management system is configured to host a collaboration event that includes first and second event endpoints that provide respective first and second sets of audio/visual (A/V) media streams to respective first and second sets of attendees during the first event. The event management system is configured to, while hosting the collaboration event, reconfigure the collaboration event to cause a third event endpoint to provide a third set of audio/visual (A/V) media streams to at least one of the first set of attendees.

Reconfiguring a collaboration event

A projector/camera system includes a projector, configured to project a sequenced image to a projection location, and a camera, located at the projection location and oriented to take an image of a region including the projector. The camera is configured to capture a sequenced image that is synchronized and out of phase with the sequenced image of the projector, thereby to minimize light interference from the projector.

A personal entertainment system calibrated and controlled by the biological or physiological condition of a user is disclosed. The entertainment system includes a media player; a sensor operative to detect biological parameters and generating a control signal in response to the detected parameters, the sensor being operably coupled to the media player; and a processing element which associates the control signal to at least one type of media preference, and causes the media player to provide media stimuli based on the control signal. Thus the media stimuli provided by the entertainment system is specific to the individual preferences and detected condition of the user.
