Embodiment 2

[0046] The embodiment of the present invention provides a data security method, such as Figure 2a shown, including:

[0047] Step 201, receiving indication information.

[0048] Wherein, the indication information includes the identification information and identification information.

[0049] In this embodiment, the terminal device can receive the indication information input by the user through the input device, the indication information is used to instruct the terminal device to mark the data specified by the user, and the identification information included in the indication information is used for the terminal device to identify the data specified by the user. Designated data, the identification information is used to mark the data designated by the user corresponding to the identification information.

[0050] It should be noted that the identification information, the specific information format of the identification information, and the specific implementation for ...

Embodiment 3

[0076] The embodiment of the present invention provides a data security device, such as image 3 shown, including:

[0077] The decryption module 31 is used for decrypting the data according to the received password.

[0078] The detection module 32 is configured to detect whether the decrypted data is currently being read or written every specified time.

[0079] The timing module 33 is configured to start timing when the read and write ends when the detection module detects that the decrypted data is currently being read and written.

[0080] The encryption module 34 is configured to re-encrypt the data if the decrypted data has not been read or written within the preset time period.

[0081] The file encryption device provided by the embodiment of the present invention can not re-encrypt the data that is being read or written within a specified time after the data is decrypted, and if the decrypted data is not used within the preset time, the decrypted data to re-encrypt...

Abstract

The embodiment of the invention discloses a data encryption method and device and relates to the technical field of electronic information, and the method and the device can be used for reducing the frequency of inputting passwords for data in use of a user and saving the time and work load of the user so as to improve the user experience. The data encryption method comprises the following steps of: decrypting the data according to the received passwords; detecting whether the decrypted data are written and read at present; and keeping the decryption state of the decrypted data or encrypting the decrypted data again according to preset rules. The data encryption method and device are applicable to data confidentiality.

Description

technical field [0001] The invention relates to the technical field of electronic information, and in particular, to a data security method and device. Background technique [0002] With the development of electronic information technology, the encryption technology on personal terminals has become more and more mature, especially encryption methods such as password authentication and fingerprint recognition, which ensure the security of information stored by users on terminal devices. [0003] In the prior art, users who want to use encrypted information, applications, etc., mainly need to go through the following processes: [0004] Every time you open an encrypted document or application, you need to manually enter the password. If you want to open a series of information encrypted by the same password, you need to re-enter the password. For example, many readers can directly read the RAR format compressed package. The content in the compressed package, and the decompres...
