Abstract
The invention provides a method for tracing a source of sensitive information, wherein the sensitive information is multimedia content issued by a user, and the method comprises the following steps: pictures, video, audio, music, voice, etc. In order to protect the sensitive information, before the information is released or before the sensitive information is captured by a user, a unique digital watermark of the current user is embedded in a verified APP user graphical interface. And adding a digital signature and a forwarding date to the digital watermarking source chain by other users before forwarding the sensitive content. When sensitive information is leaked, a transponder signature and a transponder date can be extracted through the watermark and the source chain, and transponder information is obtained through the social network, so that a user who leaks the information can be searched and tracked.
Description
Technical Field
The invention relates to sensitive content protection, in particular to a sensitive information source preparation method.
Background
Tracing is used to protect sensitive content from being leaked. A common method is to add Digital Watermark (Digital Watermark) into protected content, which is a kind of protected information embedded into carrier file by using computer algorithm, and is a computer information hiding technique based on content and non-cipher mechanism.
In order to effectively protect sensitive information and protect individual privacy, it is desirable to have a method that embeds user-unique digital watermarks into the sensitive information to be transmitted before the content of the social network is transmitted, so as to capture the source of the content and track the transmitter.
Disclosure of Invention
The invention provides a method for tracing a source of sensitive information, wherein the sensitive information is multimedia content issued by a user, and the method comprises the following steps: pictures, video, audio, music, voice, etc. In order to protect the sensitive information, before the information is released or before the sensitive information is captured by a user, a unique digital watermark of the current user is embedded in a verified APP user graphical interface.
Preferably, when the sensitive content is forwarded, the digest source chain including the transponder signature and the forwarding date is added to the personalized digital watermark, and the digest source chain is signed by all the transponders and records the date on which the content is forwarded.
Further, when other users transcribe the multimedia content, the digital watermark information is also collected together, and the forwarding date is signed and recorded on the source chain.
Furthermore, when the user or another person performs a screen capture operation, a picture taking screen or other transcription operations, the digital watermark information is collected together, and the signature and the record forwarding date are signed and recorded on the source chain.
Furthermore, the method for embedding the digital watermark in the sensitive content is applied to the APP, the PC/Mac and the webpage of the mobile phone, and sensitive information is effectively prevented from being leaked without permission.
Preferably, when sensitive information is leaked, a transponder signature and a forwarding date can be extracted through the watermark and the source chain, and transponder information is obtained through the social network to find and track a user who leaks the information.
Preferably, when the digital watermark is added to the sensitive content, it is ensured that the watermark is not easy to be viewed, so that the normal identification and viewing of the multimedia content are not affected, that is, the quality of the multimedia content is not affected after the digital watermark is added.

fig. 2 is a tracking flow of a digital watermark of sensitive content according to an embodiment of the present invention.
Detailed Description
The invention will now be described in further detail with reference to the drawings and preferred embodiments. The drawings are simplified schematic diagrams illustrating the basic principles, basic structures and basic functions of the present invention in a schematic manner, and thus show only the constituents related to the present invention.
One of ordinary skill in the art may recognize certain variations and equivalents of the invention, which should not be construed as beyond the scope of the invention.
Fig. 1 is a flowchart of an embodiment of the present invention for digitally watermarking sensitive content. As shown in fig. 1, the content publisher installs the plug-in embedded with personalized digital watermark of the present invention, and the plug-in can automatically add the personalized digital watermark, signature and publication forwarding date of the content publisher to the content. S11: installing the personalized digital watermark plug-in at the social network client (which can be a mobile phone app, or a PC/Mac or a webpage); s12: embedding a publisher personalized watermark in the content when the screenshot content is converted or the sensitive content is published, and signing and recording a publication date in the news source chain; s13: propagating the content embedded with the personalized digital watermark through the social network; s14: after the content is received by others, the digital watermark embedded in the content is unchanged when the content is transmitted or transmitted by screen capture, and meanwhile, a forwarder signs and records the date on a source chain. Therefore, when the content is transmitted in the social network, the forwarder and the news source can be tracked through the digital watermark and the news source chain.
Fig. 2 is a tracking flow of a digital watermark of sensitive content according to an embodiment of the present invention. As shown in fig. 2, when the sensitive content needs to be sourced and the propagator is tracked, S21: the content is sent to a sensitive content digital watermark tracking server deployed at the cloud end through a mobile phone App or a web browser; s22: after receiving the content, the server extracts the personalized digital watermark and the signature and forwarding date of the terminal broadcaster of the source chain; s23: obtaining forwarder information from the social network operation platform according to the forwarder signature; s24: after tracing the content propagator, generating the content tracing result (sequential forwarder and forwarding date) list; s25: and sending the tracking result list to the content tracker.
While certain features of the described implementations have been illustrated as described herein, many modifications, substitutions, changes, and equivalents will now occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the scope of the embodiments. It is to be understood that the specific features of the described implementations are presented by way of example only, and not limitation, and various changes in form and detail may be made. Any portion of the apparatus and/or methods described herein can be combined in any combination, except mutually exclusive combinations. Implementations described herein may include various combinations and/or subcombinations of the functions, components and/or features of the different implementations described.
