46820 随着移动互联网的高速发展与智能终端的迅速普及，基于位置的服务（LBS, location-based service）已在导航、社交等领域得到广泛应用。 With the development of mobile Internet and the popularization of intelligent terminals, location based servic-es(LBS) has been widespread in navigation, social network and other fields.
46821 但由于个人位置信息的敏感性，移动对象位置相关的数据隐私保护已经成为 LBS中的研究热点。 Due to the sensitivity of personal locationinformation, data privacy protection related to location of mobile objects has become the hotspots of research.
46822 综合考虑用户所处区域背景信息的开放性特征，引入信息缓存机制，提出一种虚假位置选择算法，有效减少用户与不可信服务器间的交互次数，并结合 k-匿名技术实现了用户位置信息的高效隐私保护。 Consider-ing the openness of the background information, and based on the information cache mechanism, a dummy selection al-gorithm was proposed to reduce the number of interactions between the user and the untrusted server and combine thek-anonymity to achieve efficient location privacy.
46823 相对于现有技术，该方案不依赖任何可信第三方，可实现抵御拥有背景信息攻击者的推理攻击。实验结果证明了所提方案的有效性和高效性。 Without relying on trusted third party, the scheme can prevent the at-tackers owned background information from inference attack, and the detail simulation results indicate its effectivenessand efficiency.
46824 针对现有彩色图像插值算法的实时性及可靠性不能兼备的问题，提出了一种高效的实时彩色图像缩放算法，算法基于 Lanczos 核生成可应用于整个目标图像的核查找表，并且目标图像所有像素的插值仅涉及定点小数运算，计算复杂度低； In order to improve the timeliness and reliability of color image scaling algorithms, a high effective real-timecolor image scaling algorithm was proposed, which first generated the kernel look up table that could be used for wholetarget image based on Lanczos kernel, and interpolation of all target image pixels had only fixed point operation whichhad low computational complexity.
46825 同时算法采取了优化的光栅扫描方法，内存需求低、效率高。 Meanwhile, an optimized method for rasterizing pixels of target image was proposed,which needed little memory space but embraced high efficiency of memory utilization.
