Various potential context-aware technologies and AAC usage scenarios were studied, and an efficient communication system was developed by combining smartphone's multimedia functions and its optimized sensor technologies. The experimental results show that context-awareness accuracy is achieved up to 97%.展开更多

文摘在对享受基于位置服务(LBS)用户进行位置隐私保护时,传统k-匿名技术在执行匿名操作时没有全面考虑时间开销和位置背景信息。针对上述问题,提出了一种基于Alt-Geohash编码的k-匿名位置隐私保护方案(k-anonymous location privacy protection scheme based on Alt-Geohash coding,KLPPS-AGC)。首先,通过位置泛化和Alt-Geohash编码技术实现对历史数据的快速检索;其次,根据历史查询概率筛选出能与用户构建高位置熵的位置;再次,利用海伦公式改善匿名集的位置分散度;最后,构建安全匿名集实现对用户的位置隐私保护。实验证明,该方案拥有较低的时间开销和较高的隐私性。
