Android取证中地理位置信息提取与分析研究 Extraction and Analysis of Location-Based Information in Android Forensics

Android手机在日常使用中产生了大量的地理位置信息。在手机取证中，这些信息能够有效反映用户的行为轨迹，具有重要的证据价值，同时也能为案件侦查提供线索。构建Android取证中地理位置信息提取分析的实现模型，探讨对Android取证中地理位置信息的提取、分析及证据可视化展示，为案件侦查取证提供新的思路。 Android smartphones generate a lot of location-based information. In mobile forensics, location information, which effectively reflects users’ behavior trace, shows very high investigative value and evidence value. This paper builds a forensics process model to extract, analyze and display location-based information in order to provide new ideas for case investigation.
