摘要：
Synergetic neural network (SNN) associates synergetics with artificial neural network, it can rigorously deal with the behavior of network in the mathematical theory, and have the advantage of fast learning, short pattern recalling time and so on. In this paper, a pattern recognition method based on the self-adaptive attention parameters presented on the basis of analyzing the key technology of SNN, and the advanced algorithm will be employed in the online writeprint identification, the key point of this algorithm is that it can correct initial mis-identified patterns through measuring similarity between the prototype pattern and the testing pattern in the evolution of order parameters. Experimental results show that the advanced SNN has better performance and robustness than the SNN based on balanced attention parameters. Further, the network's self-learning ability and recognition performance is greatly improved by using advanced SNN.

摘要：
The explosive growth of multimedia content on the internet is revolutionizing the way of content distribution and presenting new challenges to content security and copyright management. Encryption and watermarking are the most common techniques used to protect copyrighted multimedia content, but both have some limitations. In order to solve the problem, we probe into a new way that is to design a digital rights management (DRM) system based on FFmpeg, the system offers a reproducible and reliable alternative for digital rights management and related applications on the Internet. The protection works by encrypting the packets of key frames. Experiments have proved that encrypting the packets of key frames to protect the digital content of video is available. Other players either can't open the Encrypted video files, or the image is a mosaic and blurred image. Playing the file in the player we developed is fluent, all played properly, and the purpose of digital content protection is achieved.

摘要：
Detecting, filtering and blocking the illegal and inappropriate content on the Internet by using Internet content rating technology are important for Internet cultural security, but the lack of relevant technical standards impedes the industrialization and large-scale applications of this technology seriously. To solve this problem, this paper discusses how to establish the Internet Content Rating technical standards. Firstly, we analyze the state of the art of the Internet content rating technology standards. Secondly, we describe our method for the technical standard system development in detail. After that, we construct a complete technology standard prototype system for the Internet content rating service, and describe the components of the standard system and their relations. Finally, we discuss the follow-up works briefly.
