TL;DR: Steganography is a technique of hiding information in digital media as discussed by the authors, where the message or encrypted message is embedded in a digital host before passing it through the network, thus the existence of the message is unknown.
Abstract: Due to advances in ICT, most information is kept electronically. Consequently, the security of information has become a fundamental issue. Besides cryptography, steganography can be employed to secure information. Steganography is a technique of hiding information in digital media. In contrast to cryptography, the message or encrypted message is embedded in a digital host before passing it through the network, thus the existence of the message is unknown. Besides hiding data for confidentiality, this approach of information hiding can be extended to copyright protection for digital media: audio, video, and images.

TL;DR: In this paper, a streamlined computer device and a graphical user interface that organizes interface elements into views of computer content for presentation to a user are presented to allow users to easily and efficiently access various digital media content.
Abstract: Various aspects and embodiments are directed to a streamlined computer device and a graphical user interface that organizes interface elements into views of computer content for presentation to a user. Various views of digital media content permits users to easily and efficiently access various digital media content. Different views are used to provide an interface that is responsive to configurations of the device and responsive to activity being performed by the user. Aspects include permitting the user to maintain and manage digital media content libraries. According to some embodiments, the libraries comprise user digital media content and references digital media content. Functionality provided to a user can be tailored to the type of content displayed, accessed and/or managed. According to various aspects, methods and systems are provided for accessing and managing digital media libraries on a streamlined computing device with a plurality selectable I/O profiles.

TL;DR: In this paper, a system and corresponding methods for automating the execution, measurement, and optimization of in-store promotional digital media campaigns are provided, and a method for deploying content to digital signage networks includes receiving from a user a marketing campaign goal and at least one optimization constraint suitable for generating a playlist.
Abstract: A system and corresponding methods for automating the execution, measurement, and optimization of in-store promotional digital media campaigns are provided. In one embodiment, a method in a computing system for deploying content to digital signage networks includes receiving from a user a marketing campaign goal and at least one optimization constraint suitable for generating a playlist. The method also includes generating a playlist designed to maximize a learning opportunity to achieve the marketing campaign goal. The method further includes provisioning the playlist to a point of presence on the digital signage network.

TL;DR: In this paper, the authors rely on quantitative and qualitative methodologies to define online engagement as a collection of experiences, and demonstrate that there are two important types of engagement (personal and social-interactive engagement) for media companies, and demonstrates their predictive validity by showing both are associated with readership.
Abstract: Engagement has emerged as an important concept for newsorganizations. Yet lack of agreement within the industry and the academy on the definition of engagement has left news companies vulnerable to the definitions dictated by advertisers, who focus on brand placement not news content. This paper relies on quantitative and qualitative methodologies to define online engagement as a collection ofexperiences, illustrates that there are actually two important types of engagement (personal and social-interactive engagement) for media companies, and demonstrates their predictive validity by showing bothare associated with readership.

TL;DR: This paper provides a functional inventory of image watermarking applications and emphasizes the dependency between the application purpose and its need for invisibility, and presents a global framework common to most existing water marking systems.
Abstract: Digital watermarking consists of hiding subliminal information into digital media content, also called host data. It can be the basis of many applications, including security and media asset management. In this paper we focus on the imperceptibility requirement for image watermarking. We first provide a functional inventory of image watermarking applications and emphasize the dependency between the application purpose and its need for invisibility. Then, we present a global framework common to most existing watermarking systems. It illustrates the methodology followed to translate human vision research into watermarking technology. It suggests future prospects and highlights the need for dedicated inputs from the human vision community.
