Drawings
The foregoing is only an overview of the technical solutions of the present invention, and in order to make the technical solutions of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and the detailed description.
FIG. 1 is a flowchart of a fast self-destruction method for hard disk data according to an embodiment of the present invention;
FIG. 2 is a flowchart of a fast self-destruction method for 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 another embodiment of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
In order to rapidly complete the self-destruction of the hard disk data storage structure and ensure the data security, the technical scheme provided by the embodiment of the invention is to erase the boot partition of the hard disk. After the erasing operation is performed, the boot program cannot be started because the boot partition of the hard disk does not have any data, so that the safety of 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, and thus the total data amount of erasure is relatively small, so that the erasure operation can be performed quickly.
In various embodiments of the present invention, the boot partition typically includes: and f, performing fastboot partitioning in an Android system.
Furthermore, the hard disk storage data format typically includes: jffs format, or yaffs format.
Fig. 1 shows a flow of a fast self-destruction method for hard disk data according to an embodiment of the present invention. The flow shown in fig. 1 is applicable only to the jffs hard disk data format. Referring to fig. 1, the method for fast self-destruction of hard disk data includes:
and S11, determining the inode related to the fastboot partition.
At S12, the storage data of the inode concerned is erased.
In the embodiment shown in fig. 1, the storage format of the hard disk is jffs format. In order to ensure the completeness of data erasure, the inodes storing the fastboot partition data are calculated first, and then the inodes are erased one by one. Due to the fact that data erasure is more thorough, erasure of the fastboot partition is conducted by the implementation mode, and data security can be further guaranteed.
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 fast self-destruction method for 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 method for fast self-destruction of hard disk data includes:
and S21, determining tnode related to the fastboot partition.
And S22, erasing the storage data of the involved tnode.
Similar to the embodiment shown in fig. 1, the embodiment shown in fig. 2 also determines all involved tnodes, and then performs a uniform data erasure on the involved tnodes.
Fig. 3 shows a structure of a fast self-destruction system of hard disk data according to still another embodiment of the present invention. Referring to fig. 3, for example, the fast self-destruction system 300 of hard disk data can be used to serve as a hard disk self-destruction device in a computer system. As described herein, the fast self-destruction system 300 of hard disk data may be used to implement fast self-destruction functionality of hard disk storage structures in a computer system. The fast destruct system 300 of hard disk data may be implemented in a single node, or the functions of the fast 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-destruction system of hard disk data includes devices in a broad sense, and that the fast self-destruction system 300 of hard disk data shown in FIG. 3 is only one example thereof. The fast self-destruct system 300 of hard disk data is included for clarity 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 to 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 the fast destruct system 300 of hard disk data. For example, the features/methods of the present invention may be implemented in hardware, firmware, and/or software running installed on hardware. The fast self-destruction system 300 for hard disk data may be any device that processes, stores and/or forwards data frames through a network, such as a server, a client, a data source, etc. As shown in FIG. 3, the fast self-destruct system 300 for hard disk data may include a transceiver (Tx/Rx)310, which may be a transmitter, a receiver, or a combination thereof. Tx/Rx310 may be coupled to a plurality of ports 350 (e.g., an uplink interface and/or a downlink interface) for transmitting and/or receiving frames from other nodes. Processor 330 may be coupled to Tx/Rx310 to process frames and/or determine to which nodes to send frames. The 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.
