A Fine-Grained Flash-Memory Fragment Recog-nition Approach for Low-Level Data Recovery
文献摘要:
Data recovery from flash memory in the mobile device can effectively reduce the loss caused by data corruption.Type recognition of data fragment is an essential prerequisite to the low-level data recovery.Pre-vious works in this field classify data fragment based on its file type.Still,the classification efficiency is low,espe-cially when the data fragment is a part of a composite file.We propose a fine-grained approach to classifying data fragment from the low-level flash memory to improve the classification accuracy and efficiency.The proposed meth-od redefines flash-memory-page data recognition problem based on the encoding format of the data segment,and applies a hybrid machine learning algorithm to detect the data type of the flash page.The hybrid algorithm can sig-nificantly decompose the given data space and reduce the cost of training.The experimental results show that our method achieves better classification accuracy and higher time performance than the existing methods.
