Embodiment 1

[0037] According to an embodiment of the present invention, an embodiment of a data recovery method is provided. It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, although A logical order is shown in the flowcharts, but in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0038] figure 1 is a flowchart of a data recovery method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0039] Step S102, acquiring the character string of the data to be restored.

[0040] Specifically, in the above steps, the above-mentioned data to be restored may be computer data that is incorrectly displayed or displayed as garbled characters due to the adoption of a decoding method that does not match the encoding method, including ...

Embodiment 2

[0113] According to an embodiment of the present invention, an embodiment of a data recovery device is also provided. The data recovery method in Embodiment 1 of the present invention can be implemented in the device in Embodiment 2 of the present invention.

[0114] Figure 7 is a schematic diagram of a data recovery device according to an embodiment of the present invention, such as Figure 7 As shown, the device includes: an acquisition module 701 , a first encoding module 703 , a first decoding module 705 and a first output module 707 .

[0115] Among them, the obtaining module 701 is used to obtain the character string of the data to be restored; the first encoding module 703 is used to encode the character string of the data to be restored by using at least one encoding algorithm to obtain the encoding result obtained by encoding each encoding algorithm ; The first decoding module 705 is used to decode the encoding results obtained by encoding each encoding algorithm i...

Abstract

The invention discloses a data recovery method and device. Among them, the method includes: obtaining the character string of the data to be restored; using at least one encoding algorithm to encode the character string of the data to be restored respectively, and obtaining the encoding result obtained by encoding each encoding algorithm; using at least one decoding algorithm to sequentially encode each Decode the encoding results obtained by encoding with one encoding algorithm to obtain multiple decoding results; match the multiple decoding results with the pre-stored character library, and output the decoding results that meet the preset conditions. The invention solves the technical problem that the existing garbled code recovery method needs to know the encoding rules of garbled codes.

Description

technical field [0001] The invention relates to the field of computer data processing, in particular to a data recovery method and device. Background technique [0002] With the development of computer networks, electronic devices such as computers and mobile phones have become indispensable tools for people's life and work. However, when using a computer or a mobile phone to open a certain electronic document or a certain webpage, garbled characters often appear and the page cannot be displayed normally. This is because different systems and different application software adopt encoding rules for Chinese characters (for example, UTF-8, UTF-16 big endian, UTF-16 little endian, GBK, GB2312, etc.) are different. When Chinese character data is transferred between different software and systems, the source data is decoded using an uncorresponding character set. Therefore It will cause the displayed Chinese characters to become garbled. [0003] At present, for recovering data ...
