Data safety method preventing encrypted data from being exposed by table-board search tools

Abstract

The invention relates to a data safety method which prevents exposure of encryption data by desktop searching tool and includes the following steps: (A) a data safety system with secure disk function is provided; (B) when receiving a control instruction, the data safety system judges whether the control instruction is transmitted by the desktop searching tool; if the control instruction is not transmitted by the desktop searching tool, the operation of the data safety system is still controlled by the control instruction; if the control instruction is transmitted by the desktop searching tool, a reject instruction is transmitted to be stored in the desktop searching tool. When a virtual secure disk receives a control instruction, the invention judges whether the control instruction is transmitted from the desktop searching tool at first; if the judgment is 'NO', the operation of the secure disk is still controlled by the control instruction; if the judgment is 'YES', the operation is stopped to prevent the index of the virtual secure disk by the desktop searching tool, thereby reaching the efficacy of ensuring data safety and privacy.

Description

technical field [0001] The invention relates to a data security method related to encrypted data, in particular to a data security method for preventing desktop search tools from exposing encrypted data. Background technique [0002] With the popularity of computers and high-capacity storage devices, users often store a large amount of digital data in computer storage devices. However, as the amount of digitized data accumulated in the computer gradually increases, the user may not be able to quickly and accurately find the location where the data is stored, and may even forget that the data for a specific piece of content is stored in that file. Desktop Search Tool (DesktopSearch Tool) is a tool born in response to this need, such as Google Desktop Search Tool, Microsoft Windows Desktop Search, Yahoo Desktop Search and AOL Desktop Search, etc. Users can install such desktop search tools on their personal computers , use keyword search to quickly find files or items of rela...

[0009] The second case is that the user decrypts an encrypted file for normal editing in the plaintext state. Before the file is re-encrypted, the file being edited is indexed by the desktop search tool and the content is stored in its database. , leading to people who want to use the content stored in the database to steal secrets

[0010] The third case occurs when the virtual private disk is used

However, this method still requires the user to manually add the data that does not want to be indexed to the file exclusion index list, and the indexed data before being added to the file exclusion index list remains in the database of the desktop search tool just like the backup data
