More Information
Summary:The invention provides a residual area data deep extraction method based on a UBI mirror image format, and the method comprises the steps: obtaining normal UBIFS file system layer mirror image data through UBI mirror image recombination, thereby separating the residual UBI mirror image data, and deeply extracting the residual data in the system operation process through combining the structural characteristics of a UBI erasure block and the UBIFS file system node characteristics. The method provides a basis for further data analysis, and is of great significance in the field of evidence collection of Internet of Things. 本申请提出一种基于UBI镜像格式残留区域数据深度提取方法，该方法通过UBI镜像重组获取正常UBIFS文件系统层面镜像数据从而分离出剩余残留的UBI镜像数据，结合UBI擦除块的结构特点及UBIFS文件系统节点特性深度提取出系统运行过程中的残留数据，为进一步的数据分析提供基础，对于物联取证领域具有重要意义。
