Background
With the improvement of the office automation level, office automation equipment such as printers, copiers, scanners and the like are widely applied to government departments, enterprises and public institutions at all levels. Most of the current office automation equipment are internally provided with a mass storage part to improve the processing efficiency, but considerable potential safety hazard is brought, and the secret leakage caused by the office automation equipment storage part happens frequently. Through extracting the electronic documents and the operation logs of printing, copying, scanning and the like reserved in the storage part of the office automation equipment, the illegal use of the office automation equipment can be monitored and the office automation equipment with a security event can be checked afterwards.
In the current market, data extraction for storage components of office automation equipment is mainly performed by a method of performing offline data recovery after the storage components (such as hard disks) are detached from the equipment. For example, dasycarriry technologies, ltd, introduced a copier data extraction and analysis system. The system is connected with a detection host through a data line and a power line after the hard disk of the copier is detached through off-line detection, and data in the hard disk is extracted and analyzed. The system can display the picture information of hard disks of copiers of different brands on a computer, can analyze past behavior records, and can effectively avoid the leakage risk of confidential data.
When the data extraction and analysis system of the hard disk of the Darsan copying machine extracts the data of the hard disk of the copying machine, the hard disk needs to be detached from the copying machine, and the data recovery software can be adopted to scan and extract the data of the hard disk. The low-end copying machine is generally not provided with a hard disk, the medium-end copying machine and the high-end copying machine are complex in structure, difficult to disassemble, low in field inspection operability, time-consuming in magnetic disk scanning, and low in data identification rate if the copying machine adopts a special storage format. And because of the requirement of the security-related unit on office equipment management, in the actual inspection process, the off-line removal of the hard disk is not allowed, and in this case, the detection and extraction without the removal of the hard disk are required to be carried out on the data stored in the copying machine.
