TLDR
In this paper, the authors discuss the relation between DRM and mobile e-commerce and the impact of watermarking on business models for m-commerce, and highlight the role of watermarks in digital media delivery.Abstract:
E-commerce has become a huge business and a driving factor in the development of the Internet. Online shopping services are well established and will, with the advent of evolved 2G and 3G mobile networks, soon be complemented by their wireless counterparts. Furthermore, online delivery of digital media, such as MP3 audio or video, is very popular today and will become an increasingly important part of e-commerce and mobile e-commerce (m-commerce). However, a major obstacle for digital media distribution and associated business is the possibility of unlimited consecutive copying in the digital domain, which threatens intellectual property rights (e.g., copyrights). Digital rights management systems are required to protect rights and business. DRM systems typically incorporate encryption, conditional access, copy control mechanisms, and media identification and tracing mechanisms. Watermarking is the technology used for copy control and media identification and tracing. Most proposed watermarking methods use a so-called spread spectrum approach: a pseudo-noise signal with small amplitude is added to the host signal, and later on detected using correlation methods. A secret key is used to ensure that the watermark can only be detected and removed by authorized parties. Thus, watermarking is an essential component of modern DRM systems. Several standardization bodies are involved in DRM standardization. Some examples, (MPEG-4, SDMI, and DVD), are discussed in this article. Watermarking as an enabling technology is especially highlighted. Furthermore, the relation between DRM and m-commerce, and the impact on business models for m-commerce are discussed. A common experience today is that Internet e-commerce applications cannot always easily be adapted for mobile telecommunications systems. We emphasize, however, that DRM and watermarking can benefit from the additional information available in mobile telecommunications systems, and can thus help to improve rights management for digital media delivery.read more

Robust and high-quality time-domain audio watermarking based on low-frequency amplitude modification
Wen-Nung Lie,Li-Chun Chang +1 more
TL;DR: Subjective and objective tests reveal that the proposed watermarking scheme maintains high audio quality and is simultaneously highly robust to pirate attacks, including MP3 compression, low-pass filtering, amplitude scaling, time scaling, digital-to-analog/analog- to-digital reacquisition, cropping, sampling rate change, and bit resolution transformation.
Patent
Automated profiling of resource usage
TL;DR: In this paper, operating profiles for consumers of computing resources may be automatically determined based on an analysis of actual resource usage measurements and other operating metrics and assignment decisions may be made based on the profiles, and computing resources can be reallocated or oversubscribed if the profiles indicate that the consumers are unlikely to fully utilize the resources reserved for them.

Digital watermarking of text, image, and video documents
TL;DR: Current watermarking schemes may be viewed as spread-spectrum communications systems, which transmit a message redundantly using a low-amplitude, pseudo-noise carrier signal.
