Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present disclosure.

[0037] like figure 1 As shown, it is a schematic flowchart of a method for intercepting an office clipboard provided by an embodiment of the present disclosure. The method includes the following steps:

[0038] S1: Detecting an application programming interface (Application Programming Interface, API for short) in the operating system for obtaining content of the clipboard.

[0039] Specifically, HOOK can be performed on the API (Get Clipb...

Abstract

The invention provides a method for interception of an office clip board, which comprises that an application program programming interface API which is used to acquire clip board contents in an operation system is detected; when calling of the API by a process is detected, the process will be intercepted and a current process calling stack is acquired; whether a characteristic value about an office operation of the clip board exists is detected in the process calling stack; and if the characteristic value about the office operation of the clip board exists, the process will be deemed to have the operation of the office clip board, and the operation of the office clip board will be rejected. The invention provides a device for the interception of the office clip board, which comprises a detection unit, a stack acquisition unit, a characteristic value detection unit and an operation rejection unit. The method and the device for the interception of the office clip board provided by the invention can control the office clip board process, can prevent enciphered data from being copied out illegally, and can effectively solve the problem about safety control of the office clip board.

Description

technical field [0001] The invention relates to the technical field of computer processing, in particular to a method and device for intercepting an office shear board. Background technique [0002] In electronic document transparent encryption products, it is necessary to protect encrypted documents from certain operational behaviors during the process of opening and using, among which the clipboard is a very important aspect. The usual operation is to select the content to be copied and right-click to copy or press the keyboard Ctrl+C key combination, and then right-click in another process to paste or press the keyboard Ctrl+V key combination to paste the selected content into another process. [0003] The above behaviors of the general text software use the clipboard function interface opened by the WINDOWS system, so it is only necessary to intercept the relevant function interface to prevent the encrypted data from being illegally retrieved. However, the copy and past...
