With such a design, the invention has at least the following advantages:
by erasing the boot sector of the hard disk used to store data, a quick self-destruction of the hard disk storage structure can be achieved.
Drawings
The foregoing is merely an overview of the present invention, and the present invention is further described in detail below with reference to the accompanying drawings and detailed description.
FIG. 1 is a flow chart of a method for fast self-destruction of hard disk data according to one embodiment of the present invention;
FIG. 2 is a flowchart of a method for fast self-destruction of hard disk data according to another embodiment of the present invention;
fig. 3 is a block diagram of a fast self-destruction system for hard disk data according to still another embodiment of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present invention only, and are not intended to limit the present invention.
In order to rapidly complete self-destruction of a hard disk data storage structure and ensure data security, the technical scheme provided by the embodiment of the invention is that a boot partition of a hard disk is erased. After the erasing operation is executed, the boot program cannot be started because the boot partition of the hard disk does not have any data, so that the security of the data stored on the hard disk is ensured.
Moreover, the technical solutions provided by the embodiments of the present invention only perform erasure of the data stored in the boot partition, so that the total amount of data erased is relatively small, enabling the erasure operation to be performed quickly.
In various embodiments of the present invention, the boot partition typically includes: fastboot partition in Android system.
Also, hard disk storage data formats typically include: jffs format, or yaffs format.
Fig. 1 shows a flow of a method for fast self-destruction of hard disk data according to an embodiment of the present invention. Moreover, the flow shown by fig. 1 is applicable only to jffs hard disk data formats. Referring to fig. 1, the fast self-destruction method of hard disk data includes:
s11, determining inodes related to fastboot partitions.
S12, erasing the storage data of the related inode.
In the embodiment shown in fig. 1, the storage format of the hard disk is the js format. In order to ensure the thorough data erasure, the inodes storing the fastboot partition data are first calculated, and then the inodes are erased one by one. As the data is erased more thoroughly, the fastboot partition is erased by adopting the implementation mode, and the data security can be further ensured.
This has the advantage that the erasure of the boot partition is more comprehensive. In other words, the self-destruction operation of the hard disk data is more thorough.
Fig. 2 shows a flow of a method for fast self-destruction of hard disk data according to another embodiment of the present invention. Also, the flow shown by fig. 2 is applicable only to yaffs hard disk data format. Referring to fig. 2, the fast self-destruction method of hard disk data includes:
s21, determining tnode related to fastboot partition.
S22, erasing the storage data of the related tnode.
Similar to the embodiment shown in fig. 1, in the embodiment shown in fig. 2, all the tnode involved is determined first, and then a unified data erasure is performed on the tnode involved.
Fig. 3 shows a structure of a fast self-destruction system for hard disk data according to still another embodiment of the present invention. Referring to fig. 3, for example, the fast self-destruct system 300 of hard disk data may be used to act as a hard disk self-destruct device in a computer system. As described herein, the fast self-destruct system 300 for hard disk data may be used to implement fast self-destruct functions to hard disk storage structures in a computer system. The fast self-destruct system 300 of hard disk data may be implemented in a single node, or the functions of the fast self-destruct system 300 of hard disk data may be implemented in multiple nodes in a network. Those skilled in the art will appreciate that the term fast self-destruct system for hard disk data includes devices in a broad sense, with the fast self-destruct system 300 for hard disk data shown in FIG. 3 being but one example. The fast self-destruct system 300 including hard disk data is for clarity of description and is not intended to limit the application of the present invention to a specific fast self-destruct system embodiment of hard disk data or a class of fast self-destruct system embodiments of hard disk data. At least some of the features/methods described herein may be implemented in a network device or component, such as a fast self-destruct system 300 for hard disk data. For example, the features/methods of the present invention may be implemented in hardware, firmware, and/or software running on hardware. The fast self-destruct system 300 for hard disk data may be any device that processes, stores and/or forwards data frames over a network, such as a server, client, data source, etc. As shown in fig. 3, the fast self-destruct system 300 of hard disk data may include a transceiver (Tx/Rx) 310, which may be a transmitter, a receiver, or a combination thereof. The Tx/Rx310 may be coupled to a plurality of ports 350 (e.g., uplink and/or downlink interfaces) for transmitting and/or receiving frames from other nodes. The processor 330 may be coupled to the Tx/Rx310 to process the frame and/or to determine to which nodes to send the frame. Processor 330 may include one or more multi-core processors and/or memory devices 332, which may serve as data stores, buffers, and the like. The processor 330 may be implemented as a general purpose processor or may be part of one or more application specific integrated circuits (application specific integrated circuit, ASIC) and/or digital signal processor (digital signal processor, DSP).
The above description is only of the preferred embodiments of the present invention, and is not intended to limit the invention in any way, and some simple modifications, equivalent variations or modifications can be made by those skilled in the art using the teachings disclosed herein, which fall within the scope of the present invention.
