中文摘要：
依据数字水印技术的基本原理，选取适合Symbian OS的数字水印算法开发面向智能手机的数字水印认证技术，它将是数字水印技术的一个针对智能手机应用的发展方向。该文设计了一个基于Symbian平台的智能手机可认证拍照系统，重点说明系统在Symbian平台上实现时的关键技术：图像拍照、数字水印算法移植、活动对象机制等方面问题。经测试表明，该系统可以实现手机拍照、快速嵌入水印、提出水印，并能通过提取的水印达到认证原始图像是否被篡改的目的。
英文摘要：
Introduced the basic principles of digital watermarking technology＇, and the algorithm should be suited for the smartphone. It＇s a digital watermarking developing direction for intelligent mobile phone digital watermarking authentication technology. Designed a system can take pictures and make authentication based on the Symbian smartphone,and presented the key problems that should be noted when the system is implemented on Symbian （36, such as image capture, transplant of the algorithm of digital watermarking, active objects mechanism and so on . The tests showed that the system could take a picture , embed watermark and extract watermark quickly and make authentication for the original image through the extracted watermark.
