Embodiment 1

[0031] refer to Figure 2A , shows a flow chart of steps of a data security processing method according to Embodiment 1 of the present application.

[0032] This embodiment describes the data security processing method in the embodiment of the present application from the perspective of embedding a watermark. The data security processing method of this embodiment includes the following steps:

[0033] Step S202: Analyze the data structure of the carrier to be embedded with the watermark to obtain multiple structural parts that can be embedded with the watermark.

[0034] Wherein, the carrier to be embedded with the watermark can be any suitable file type carrier, including but not limited to: documents (such as text documents, form documents, web documents and other text-based files), images, audio, video, etc.

[0035] In the embodiment of the present application, data structure analysis is performed on the carrier to be embedded with the watermark to obtain each structural...

Embodiment 2

[0057] refer to Figure 3A , shows a flow chart of steps of a data security processing method according to Embodiment 2 of the present application.

[0058] This embodiment describes the data security processing method in the embodiment of the present application from the perspective of watermark extraction. The data security processing method of this embodiment includes the following steps:

[0059] Step S302: Obtain a watermark-embedded carrier and multiple structural parts included in the carrier.

[0060] Wherein, the multiple structural parts embed watermarks through multiple watermark embedding algorithms.

Abstract

The embodiment of the invention provides a data security processing method, electronic equipment and a computer storage medium, and the data security processing method comprises the steps: carrying out the data structure analysis of a carrier to be embedded with a watermark, and obtaining a plurality of structure parts capable of being embedded with watermarks; selecting a plurality of corresponding watermark embedding algorithms for the plurality of structure parts from a plurality of preset watermark embedding algorithms; performing watermark embedding processing on the content information of each structure part according to the watermark embedding algorithm corresponding to each structure part in the plurality of structure parts; and according to the watermark embedding processing result of each structure part, obtaining a carrier embedded with the watermark. According to the embodiment of the invention, the data security of the carrier is effectively improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technologies, and in particular, to a data security processing method, electronic equipment, and computer storage media. Background technique [0002] The development of Internet technology has brought many conveniences to people's work and life, but at the same time, it also poses severe challenges to data security. [0003] At present, in order to protect data security, especially for data security of files such as documents, images, audio, video, etc., watermark embedding is used for protection. Taking documents as an example, watermarks are usually embedded in redundant fields of documents. Once a document is leaked, the source of the leak can be known by extracting the watermark content. However, the watermark in this way is easy to be maliciously analyzed, so as to remove the watermark or learn the embedding and extraction logic of the watermark, and what is even more lik...
