Abstract: A print control device includes an output unit, an adding unit, and a transmitting unit. The output unit outputs generated print data to a printing mechanism. The generated print data is generated as a result of unit print data, which includes page data of at least one page, being copied; and includes pieces of the unit print data. The adding unit adds blank page data between one piece of unit print data and another piece of unit print data to be printed next in line to the one piece of unit print data. The transmitting unit transmits, to the printing mechanism, information for causing an additional image to be formed on a medium when an image based on the page data is printed on the medium, and information for causing the additional image not to be formed on a blank page formed based on the added blank page data.

Abstract: An encoding apparatus partitions a digital image into multiple regions for subsequent encoding. A first encryption code is associated with a first region, a second encryption code is associated with a second region and the first code, and a third code is associated with the first code, the second code and a third region. An authentication apparatus authenticates the digital image in an inverse process.

Abstract: In one aspect, assembly of multi-part food packaging is checked by reference to payloads of steganographically-encoded digital watermarks printed across plural components of the packaging. Marking all surfaces of the packaging components allows arbitrary orientation of feed stock in assembly equipment, and wide latitude in placement of inspection cameras along the packaging line. In another aspect, a scanner at a retail checkout station is alert to any gap detected in steganographic encoding on retail product packaging and, if found, alerts an operator to possible presence of an adhesive label with a misleading barcode. A great variety of others features and arrangements are also detailed.

Abstract: Content creation and licensing control techniques are described. In a first example, a content creation service is configured to support content creation using an image along with functionality to locate the image or a similar image that is available for licensing. In another example, previews of images are used to generate different versions of content along with an option to license images previewed in an approved version of the content. In a further example, fingerprints are used to locate images used as part of content creation by a content creation service without leaving a context of the service. In yet another example, location of licensable versions of images is based at least in part on identification of a watermark included as part of an image. In an additional example, an image itself is used as a basis to locate other images available for licensing by a content sharing service.

Abstract: In one example, a system including an isolation engine, a normalization engine, and a channel engine is described. In the example, the isolation engine generates mark data using a mark technique based on a first input color channel and a second input color channel, the normalization engine scales intensity values of a set of pixels of the mark data to a greater range, and the channel engine generates output channel data for a plurality of output color channels from normalized mark data based on the scaled intensity values.

Abstract: Methods, devices and computer program products allow improved synchronization among multiple contents. One disclosed method includes receiving a first and a second content and performing watermark extraction to recover a first timecode as part of a watermark embedded into a segment of that content. The first timecode conforms to a first type of timing system. Next, a timing system associated with the second content is determined, and a mapping is obtained that allows timecode conversion between the first and the second timing systems. Using the mapping to synchronize the presentation of the second content with that of the first content. Thus synchronization of multiple contents is properly maintained even when processing operations such as format conversion and transcoding cause metadata streams that carry timing information to be removed.

Abstract: Methods, devices and computer program products allow improved detection of watermarks into and from a multimedia content. One method for detecting watermarks from a host content includes performing watermark extraction to obtain a first sequence of watermark symbols from the host content and generating a plurality of predicted watermark templates. Each template corresponds to a sequence of watermark symbols that is predicted based on the first sequence of watermark symbols. A section of the host content is processed to obtain a candidate sequence of watermark symbols and correlation operations between the candidate sequence of watermark symbols and symbols of the predicted watermark templates are performed until a correlation result that is indicative of a successful watermark detection is obtained. An indication that the candidate sequence of watermark symbols represents at least a portion of a reliably extracted watermark message can then be produced.

Abstract: Various features described herein may allow an authorized user to provide a guest with access to a secured location through use of an encoded image containing steganographically encoded access information. The encoded access information may be recognizable by a security system, and the security system may grant access to the secured location when the encoded image is presented to the security system. The authorized user may request the generation of the encoded image on an authorized computing device, and the encoded image may be provided to the guest on a guest computing device. When a monitoring device associated with the security system captures the encoded access information, the security system may, for example, open a door at the secured location.
