METHOD AND APPARATUS FOR RECOVERING DELETED DATA ON LOW FLASH MEMORY FORMATTED WITH UBIFS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18583253 titled 'METHOD AND APPARATUS FOR RECOVERING DELETED DATA ON LOW FLASH MEMORY FORMATTED WITH UBIFS
The method described in the patent application involves recovering deleted data from a low flash memory formatted in UBIFS by analyzing the structure of different types of nodes.
- The first step involves receiving a UBI volume created by collecting memory data from the low flash memory.
- The second step includes determining the type of node by searching for a node header in all areas of the input UBI volume and recovering deleted data through structural analysis of each node type, which can be a directory node or a data node according to a B+ tree structure.
Potential Applications: - Data recovery services for devices using UBIFS formatted low flash memory. - Forensic analysis of deleted data on UBIFS formatted storage devices.
Problems Solved: - Efficient recovery of deleted data from UBIFS formatted low flash memory. - Analysis of node structures to identify and retrieve deleted data.
Benefits: - Enhanced data recovery capabilities for UBIFS formatted devices. - Improved forensic analysis of storage devices.
Commercial Applications: Title: Data Recovery Software for UBIFS Formatted Devices This technology can be utilized by data recovery companies to offer specialized services for UBIFS formatted devices, catering to individuals and businesses in need of recovering deleted data.
Questions about the technology: 1. How does the method in the patent application differ from traditional data recovery techniques? 2. What are the specific challenges associated with recovering deleted data from UBIFS formatted low flash memory?
Original Abstract Submitted
A method of recovering deleted data on a low flash memory formatted in UBIFS according to an embodiment of the present invention includes: (a) a first step of receiving a UBI volume configured by collecting memory data from the low flash memory; and (b) a second step of determining a node type by searching for a node header in all areas of the input UBI volume, and recovering deleted data through a structural analysis performed on each determined node type, wherein the determined node type is either a directory node or a data node, which are leaf nodes according to a B+ tree structure.
