计算机数据信息安全中的加密与解密技术探析

随着网络时代的到来,计算机技术不断更新,互联网已经成为人们生活不可或缺的一部分,人们的信息数据也被互联网记录着,因此社会不同行业对计算机数据信息安全提出了更高的要求。因此,加强计算机数据信息的安全管理,做好数据机密技术,对整个社会的数据信息安全保障具有重要意义。

Data Mining and Visualization of Grid-Based City Emergency System

A cluster analyzing algorithm based on grids is introduced in this paper,which is applied to data mining in the city emergency system. In the previous applications, data mining was based on the method of analyzing points and lines, which was not efficient enough in dealing with the geographic information in units of police areas. The proposed algorithm maps an event set stored as a point set to a grid unit set, utilizes the cluster algorithm based on grids to find out all the clusters, and shows the results in the method of visualization. The algorithm performs well when dealing with high dimensional data sets and immense data. It is suitable for the data mining based on geogra-(phic) information system and is supportive to decision-makings in the city emergency system.

论中国网络空间犯罪立法的本土化与国际化

网络空间犯罪是计算机犯罪、网络犯罪在网络平台时代的新相态,为了有效打击网络空间犯罪,中国刑法既要坚持本土化发展,也要借鉴国外立法的成功经验,积极推动国际社会相关立法协调一致。计算机数据和信息系统安全是独立的公共法益,应当给予全面的刑法保护。惩治网络化的传统犯罪应当坚持科学防控和法治原则,避免以刑代管,更不应突破法律规定解释立法。妨害信息网络安全管理秩序犯罪是独立的、具有"积量构罪"特征的正当立法,司法适用中应坚持独立适用和实质正当原则,合理缩限解释构成要件要素,对情节要件进行必要的类型化。充分保护个人信息符合中国国家利益、公共利益和公众利益,应在平衡个人信息法律保护和合法利用的基础上,为公民个人信息提供更全面的法律保护。
