Embodiment Construction

[0031] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] In order to overcome the above disadvantages, the present invention builds a log recording system and method based on image processing.

[0033] figure 1 It is a schematic diagram of file access of the log recording system based on image processing according to the embodiment of the present invention.

[0034] The log recording system based on image processing shown according to the embodiment of the present invention includes:

[0035] The mode switching device is used to enter the document protection operation mode when the current document is a protected document type, and is also used to enter the document normal operation mode when the current document is a non-protected document type;

[0036] A change estimating device, connected to the mode switching device, used for estimating the number of words changed in the current document in the d...

Abstract

The invention relates to a computer log recording system based on image processing. The computer log recording system comprises a mode switching device for enabling a document protection operation mode when a current document is of a protection document file and enabling a document normal-operation mode when the current document is of a non-protection document type, a change estimating device connected with the mode switching device, used for estimating changed word number of the current document in the document protection operation mode to use the percentage of estimated changed word number in the total word number of the current document as a change percentage to be output and also used for non-estimating the changed word number of the current document in the document normal-operation mode, an operation triggering device connected with the mode switching device and the change estimating device. The invention also relates to a log recording method based on image processing. By adopting the computer log recording system and the log recording method, log records of the current document are enabled when a current user is identified as a non-permission user.

Description

technical field [0001] The invention relates to the field of computers, in particular to a computer log recording system and method based on image processing. Background technique [0002] Currently, there is a security protection scheme for shared printers, but there is no effective security protection scheme for shared documents. The security protection scheme for shared printers is as follows. For example, illegal users in the local area network may also take the opportunity to use shared printers, resulting in "increasing" printing costs. In order to prevent illegal users from sharing the printer at will, it is necessary to restrict the use of the printer by setting account usage permissions. By setting the security attributes of the printer installed on the host, specify that only legal accounts can use the shared printer. [0003] If a shared document is tampered with and saved, it is difficult to retrieve the relevant information before the tampering, and the relev...
