Watermarking schemes evaluation Abstract鈥擠igital watermarking has been presented as a solution to copy protection of multimedia objects and dozens of schemes and algorithms have been proposed. Two main problems seriously darken the future of this technology though. Firstly, the large number of attacks and weaknesses which appear as fast as new algorithms are proposed, emphasizes the limits of this technology and in particu-lar the fact that it may not match users expectations. Secondly, the requirements, tools and methodologies to assess the current technologies are almost non-existent. The lack of benchmarking of current algorithms is bla-tant. This confuses rights holders as well as software and hardware manufacturers and prevents them from using the solution appropriate to their needs. Indeed basing long-lived protection schemes on badly tested watermarking technology does not make sense.

在实际项目项目开发中，很多时候需要用到邮件，比如论坛注册需要用邮件激活。 一般用Javamail发送，目前最新的版本是1.4.2 可以在http://java.sun.com/products/javamail/index.jsp 下载最新版本 如果使用的不是J2SE6，那么需要把 JavaBeans Activation Framework加到环境变量 可以在http://java.sun.com/javase/technologies/desktop/javabeans/jaf/index.jsp 下载 不过为了简化开发，可以直接使用apache common项目的mail 官方网站为: http://commons.apache.org/email/

With this example-driven book, you get a quick, practical, and thorough introduction to Java s API for XML Web Services (JAX-WS) and the Java API for RESTful Web Services (JAX-RS). Java Web Services: Up and Running takes a clear, no-nonsense approach to these technologies by providing you with a mix of architectural overview, complete working code examples, and short yet precise instructions for compiling, deploying, and executing a sample application. You ll not only learn how to write web services from scratch, but also how to integrate existing services into your Java applications. All the source code for the examples is available from the book s companion website.

The software and hardware development fields evolved along separate paths through the end of the 20th century. We seem to have come full circle, however. The previously rigid hardware on which our programs run is softening in many ways. Embedded systems are largely responsible for this softening. These hidden computing systems drive the electronic products around us, including consumer products like digital cameras and personal digital assistants, office automation equipment like copy machines and printers, medical devices like heart monitors and ventilators, and automotive electronics like cruise controls and antilock brakes. Embedded systems force designers to work under incredibly tight time-tomarket, power consumption, size, performance, flexibility, and cost constraints. Many technologies introduced over the past two decades have sought to help satisfy these constraints. To understand these technologies, it is important to first distinguish the underlying embedded systems elements.
