Abstract: Consumer uses of mobile devices and electronic media are changing. Mobile devices include increased computational capabilities, mobile broadband access, better integrated sensors, and higher resolution screens. These enhanced features are driving increased consumption of media such as images, maps, e-books, audio, video, and games. As users become more accustomed to using mobile devices for media, opportunities arise for new digital watermarking usage models. For example, transient media, like images being displayed on screens, can be watermarked to provide a link between mobile devices, extending the reach of digital watermarking. Digital fingerprinting can also be employed. Applications based on these emerging usage models can provide richer user experiences and drive increased media consumption. A great variety of other features and arrangements are also detailed.

Abstract: There are many advantages to implementing a watermark-based system using dedicated hardware, rather than using software executing on a general purpose processor. These include higher speed and lower power consumption. However, hardware implementations incur substantial design and development costs. Moreover, because each watermarking application has its own design constraints and parameters, it has not been cost-effective to develop a hardware chip design for each, since such chips would typically not be manufactured in volumes sufficient to bring per-unit costs down to an acceptable level. The present technology provides various techniques for making watermarking hardware adaptable, so that a single chip can serve multiple diverse watermark applications. By so-doing, the advantages of hardware implementation are made available where it was formerly cost-prohibitive, thereby enhancing operation of a great variety of watermark-based systems.

Abstract: Sparse signal modulation schemes encode a data channel on a host image in a manner that is robust, flexible to achieve perceptual quality constraints, and provides improved data capacity. The host image is printed by any of a variety of means to apply the image, with sparse signal, to an object. After image capture of the object, a decoder processes the captured image to detect and extract data modulated into the sparse signal. The sparse signal may incorporate implicit or explicit synchronization components, which are either formed from the data signal or are complementary to it.

Abstract: A content fingerprint based recognition system employs local caching of portions of a fingerprint database to manage network services for identifying which programs a user's mobile device is exposed to and the timing of events within the program. The system enables background recognition and synchronization of network services in a way that consumes less device power and bandwidth.

Abstract: In one particular arrangement, a smartphone camera is moved by a user to capture dermatologic imagery from a variety of viewpoints. When the user thereafter holds the phone in a particular pose (e.g., with the display inclined upwardly, and with a display edge oriented substantially horizontally), the device switches to a display mode—presenting information derived from the earlier-captured dermatologic imagery. The device thus switches automatically between data collection and data presentation modes, based on pose and motion. A great variety of other features and arrangements are also detailed.

Abstract: Content fingerprints and watermarks are combined in various ways for content identification applications. Fingerprints are used to identify content generally while watermarks provide more detailed localization of parts within the content, and vice versa. Fingerprint techniques are further used for signal synchronization and other pre-processing steps to assist in digital watermark decoding. A variety of fingerprint/watermark techniques identify characteristics of the channel of content from content samples.

Abstract: Watermarking media content, in combination with blockchain and distributed storage networks, prevents the proliferation of Deepfake content. Digital watermarks are embedded in the audio and video tracks of video clips of trusted content producers at the time the videos are captured or before they are distributed. The watermarks are detected at the social media network's portals, nodes, and back ends. The embedded watermark imparts a unique identifier to the video, that links it to a blockchain. The watermarks also allow video source tracking, integrity verification, and alteration localization. The watermark detectors can be standalone software applications, or they can be integrated with other applications. They are used to perform three main tasks: (1) they alert the Internet user when he watches an inauthentic news video, so that he may discard it, (2) they prevent a Deepfake content from propagating through the network (3) they perform forensic analysis to help track and remove Deepfake content postings.
