ABSTRACT Internet voice and video calling have demonstrated a dramatic rise in quality in the past several years and have quickly become communication technologies with a disruptive impact on society. Librarians, who regularly adopt such technologies in outreach and public services, should evaluate Web-calling programs as potential sources of innovative reference programming. This article describes the development of Skype video and Internet telephony pilot reference services at the Ohio University Libraries and considers the utility of Skype and VoIP in a library setting. 相似文献

Skype is one of the most popular voice-over-IP (VoIP) service providers. One of the main reasons for the popularity of Skype VoIP services is its unique set of features to protect privacy of VoIP calls such as strong encryption, proprietary protocols, unknown codecs, dynamic path selection, and the constant packet rate. In this paper, we propose a class of passive traffic analysis attacks to compromise privacy of Skype VoIP calls. The proposed attacks are based on application-level features extracted from VoIP call traces. The proposed attacks are evaluated by extensive experiments over different types of networks including commercialized anonymity networks and our campus network. The experiment results show that the proposed traffic analysis attacks can greatly compromise the privacy of Skype calls. Possible countermeasure to mitigate the proposed traffic analysis attacks are analyzed in this paper. 相似文献

提出了一种基于行为特征描述的P2P流识别算法(BCCIA).首先建立了基于行为特征描述的P2P流的规范化统一描述,并定义了关键字的文法规则.接着,在BCCIA算法中,采用基于均匀分布的Hash函数来实现匹配和加快匹配速度,并详细阐述了模式识别的具体实现步骤.最后,在Linux环境下,以Skype为例进行仿真试验.实验数据表明,采用BCCIA算法,可以很好地实现分类和标识P2P流. 相似文献
