Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is capable of implementation in many different ways than those herein set forth and of similar import by those skilled in the art without departing from the spirit of this application and is therefore not limited to the specific implementations disclosed below.

A first embodiment of the present application provides a watermark embedding method, which is described in detail below with reference to fig. 1, fig. 2, fig. 3, and fig. 4.

As shown in fig. 1, in step S101, watermark information that needs to be embedded in the carrier object is obtained.

The carrier object refers to an object to be embedded with watermark information. The carrier object, an index carrier, comprising: web pages, images, etc.

The watermark information refers to identification information to be embedded into the carrier object. The watermark information can be hidden and embedded into the carrier object, the use value of the original carrier object cannot be influenced, and the watermark information is not easy to be ascertained and modified again. But the watermark information can be identified and recognized by the producer. The watermark information hidden in the carrier can achieve the purposes of confirming content creators and purchasers, transmitting secret information, judging whether the carrier object is tampered or not and the like. The watermark information may be a company name of a certain company, or may be an employee number or other identification information of a certain employee.

As shown in fig. 1, in step S102, the watermark information is converted into a barcode image.

After watermark information to be embedded into the carrier object is obtained, the watermark information is converted into a bar code image. As shown in fig. 2, which is a bar code image converted according to certain watermark information.

In particular implementations, the watermark information may be converted to a barcode image according to Code39 encoding. Code39 is a type of barcode, also called 3of9Code, USD-3, or logars, and is widely used because of its characteristics such as simple construction, capability of encoding data of an arbitrary length, and support of a wide range of devices.

Besides the standard bar code coding rule, in order to increase the information quantity of the embedded watermark information, a set of coding rule can be designed by self, fewer 0/1 sequences are used for representing more characters, and the watermark information is converted into a bar code image according to the designed coding rule.

As shown in fig. 1, in step S103, the barcode image is subjected to a disguise process to obtain a disguise element disguised as an element of the carrier object.

In order to embed the barcode image in step S102 into the carrier object in a hidden manner, it is necessary to perform a disguising process on the barcode image, obtain a disguise element disguised as an element of the carrier object, and then embed the disguise element into the carrier object.

The camouflaging the barcode image to obtain camouflaged elements camouflaged as elements of the carrier object includes:

and intercepting the bar code image to obtain a camouflage element containing the watermark information.

Intercepting the bar code image to obtain a camouflage element containing the watermark information, wherein the step of intercepting the bar code image comprises the following steps: and respectively intercepting each stripe in the bar code image in the longitudinal direction to obtain a dotted line or black and white block set containing the watermark information.

In a specific implementation, the barcode image may be cut into a dotted line with a height of one pixel or several pixels, and the dotted line contains the watermark information, or the barcode image may be cut into a set of black and white blocks containing the watermark information.

Preferably, the barcode image is intercepted according to the shape of the element on the carrier object, so as to obtain a camouflage element which is matched with the shape of the element on the carrier object and contains the watermark information;

the longitudinally intercepting each stripe in the barcode image to obtain a dotted line or black and white block set containing the watermark information includes:

and respectively intercepting each stripe in the bar code image in the longitudinal direction according to the element shape on the carrier object to obtain the dotted line or black and white block set which is matched with the element shape on the carrier object and contains the watermark information.

For example, if the carrier object is a web page having a black and white solid line with a pixel height of 1 on the web page, the barcode image may be cut out according to the shape of the solid line of the web page, and a dotted line with a pixel height of 1 containing watermark information is cut out from the barcode image, fig. 3 is a dotted line cut out according to the barcode image of fig. 2, and the cut-out dotted line is a dummy element.

For another example, if the carrier object is a web page and a black and white block set exists on the web page, the barcode image may be intercepted according to the shape of the black and white block set of the web page, the black and white block set matching the black and white block shape on the carrier object is intercepted from the barcode image, the intercepted black and white block set is a disguise element, and when embedding, the disguise element (black and white block set containing watermark information) may be embedded in the position of the black and white block set of the web page.

Preferably, the color of the set of black and white blocks or dotted lines containing the watermark information is adjusted according to the color of the carrier object.

Preferably, the color of the barcode image is adjusted according to the color of the carrier object, so as to obtain the barcode image with the adjusted color;

intercepting the bar code image to obtain a camouflage element containing the watermark information, wherein the step of intercepting the bar code image comprises the following steps:

intercepting the bar code image after the color is adjusted to obtain a camouflage element containing the watermark information.

The color of the set of dashed or black-and-white blocks containing the watermark information can be adjusted if there is a color at the location on the carrier object where the disguise element is to be embedded. For example, if a disguise element (dotted line) is to be embedded at the position of a solid red line on the carrier object, the black part of the dotted line can be adjusted to a deep red and the white part of the dotted line to a light red.

If the position of the carrier object to be embedded with the camouflage element has color, the color of the bar code image can be adjusted according to the color of the carrier object to obtain the bar code image with the adjusted color; and intercepting the bar code image after the color is adjusted to obtain a camouflage element containing watermark information, and embedding the camouflage element into the carrier object. For example, if the disguise element is to be embedded in the position of a red solid line on the carrier object, the color of the barcode image may be adjusted according to the color of the carrier object, the black part of the barcode is adjusted to be dark red, and the white part of the barcode is adjusted to be light red, so as to obtain the barcode image with the adjusted color; and intercepting the bar code image after the color is adjusted to obtain a camouflage element (a dotted line) containing watermark information, and embedding the camouflage element into the carrier object.

As shown in fig. 1, in step S104, the camouflage element is embedded in the carrier object.

Embedding the disguised element into the carrier object, comprising:

judging whether an element matched with the camouflage element in shape exists in the carrier object;

if yes, embedding the camouflage element into the position of the element; or, embedding the disguised element in an adjacent position to the element;

if not, randomly embedding the camouflage elements into the carrier object; or, according to the relationship of each element in the carrier object, the disguise element is embedded into the boundary on the spatial layout of the carrier object.

When the carrier object is concretely implemented, the camouflage element is embedded into the carrier object in various ways, if an element with a shape matched with that of the camouflage element exists in the carrier object, the camouflage element can be embedded into the position where the element with the shape matched with that of the carrier object exists, that is, the element with the shape matched with that of the carrier object is replaced by the camouflage element, for example, if the camouflage element is a dotted line containing watermark information and the dotted line exists in a webpage, the camouflage element can be embedded into the position of the dotted line on the webpage and the original dotted line is replaced by the camouflage element; or the disguised element may be embedded at a position adjacent to the dotted line, for example, if the disguised element is a dotted line containing watermark information and the dotted line exists in the web page, the disguised element may be embedded at an upper adjacent position or a lower adjacent position parallel to the dotted line on the web page. If the carrier object does not have an element matching the shape of the disguise element, the disguise element may be randomly embedded into the carrier object, for example, if the disguise element is a dotted line containing watermark information and no dotted line or solid line exists in the web page, as shown in fig. 4, the disguise element may be added above or below a line of text of the carrier object, as shown in fig. 5; or, according to the relationship of each element in the carrier object, the disguised element is embedded into a boundary on the spatial layout of the carrier object; the boundary may refer to a boundary of a DIV element in a web page. In order to avoid that the watermark extraction fails due to the fact that part of the data of the carrier object is damaged, the disguise element can be embedded into the carrier object for multiple times when the disguise element is embedded into the carrier object.

Said embedding said disguised element into said carrier object comprises:

embedding the camouflage element laterally into the carrier object; and/or

Longitudinally embedding the camouflage element into the carrier object.

For example, if there is a solid line or a dashed line in the horizontal direction on the web page, the disguise element may be embedded in the horizontal direction at the position of the solid line or the dashed line, i.e., the solid line or the dashed line on the web page is replaced by the disguise element; if the webpage has a longitudinal solid line or a longitudinal dotted line, the disguised element can be rotated to be a vertical dotted line and then longitudinally embedded at the position of the solid line or the dotted line on the webpage.

In order to enable the watermark extraction end to more accurately obtain the position of watermark embedding, the watermark embedding end may notify the watermark information extraction end of the determined embedding position information.

Now, a detailed description is given of an implementation of the watermark embedding method provided in the first embodiment of the present application. According to the method and the device, the disguise element disguising as the element of the carrier object is embedded into the carrier object, the disguise element containing the watermark information is not easy to find by an attacker, and the method and the device can resist screenshot and photographing attack, namely, data are obtained and leaked in a screenshot or photographing mode, and the source can still be traced, so that the safety problem of the watermark embedded into the carrier object is solved.

and determining the position information of the camouflage elements in the carrier object according to the change of the color gray value of the carrier object.

For example, if the background color of the web page is grey, if a dashed line of one of the other colors appears at a certain position, this position may be the position of the disguised element in the carrier object.

The extracting of the disguise element disguised as the element of the carrier object from the carrier object includes:

A ninth embodiment of the present application provides a data processing method, which is described in detail below with reference to fig. 14.

As shown in fig. 14, in step 1401, a carrier object and first identification information are obtained, where the carrier object includes a first display element.

The carrier object refers to an object in which the first identification information needs to be embedded. The carrier object, an index carrier, comprising: web pages, images, etc.

The first identification information can be embedded into the carrier object, the use value of the original carrier object cannot be influenced, and the first identification information is not easy to be detected and modified again. The first identification information may be a company name of a certain company, or may be an employee number of a certain employee or other identification information.

The first display element comprises elements such as a dotted line or a black and white block set in the carrier object.

As shown in fig. 14, in step 1402, the first identification information is converted into second identification information corresponding to the first display element.

The correspondence may mean that the shape of the second identification information matches the shape of the first display element. For example, if the first display element is a dotted line, the second identification information is also a dotted line; if the first display element is a set of black and white blocks, the second identification information is also a set of black and white blocks.

Converting the first identification information into second identification information corresponding to the first display element, including:

converting the first identification information into an intermediate image;

converting the intermediate image into second identification information corresponding to the first display element.

The converting the first identification information into an intermediate image may include:

obtaining a bit sequence corresponding to the first identification information according to the first identification information;

determining the width of the stripe and the width of the gap according to the bit sequence;

and obtaining the intermediate image according to the width of the stripe and the width of the gap.

The intermediate image comprises a barcode image.

In particular implementations, when the intermediate image is a barcode image, the above steps may be used to convert the first identification information into the barcode image according to Code39 encoding. Code39 is a type of barcode, also called 3of9Code, USD-3, or logars, and is widely used because of its characteristics such as simple construction, capability of encoding data of an arbitrary length, and support of a wide range of devices.

Besides the standard bar code encoding rule, in order to increase the information quantity of the embedded first identification information, a set of encoding rule can be designed by self, fewer 0/1 sequences are used for representing more characters, and the watermark information is converted into an intermediate image according to the designed encoding rule.

The converting the intermediate image into second identification information corresponding to the first display element includes:

and intercepting the intermediate image to obtain second identification information corresponding to the first display element.

The converting the intermediate image into second identification information corresponding to the first display element includes:

and respectively intercepting each stripe in the intermediate image in the longitudinal direction to obtain second identification information corresponding to the first display element.

For example, if the carrier object is a web page having a black and white solid line with a pixel height of 1 on the web page, the intermediate image (e.g., the barcode image) may be cut according to the shape of the solid line of the web page, a dotted line (second identification information) with a pixel height of 1 may be cut from the intermediate image, and the dotted line including the first identification information may be embedded at the position of the solid line of the web page.

For another example, if the carrier object is a web page and the web page has a black and white block set, the intermediate image (for example, a barcode image) may be cut according to the shape of the black and white block set of the web page, the black and white block set matching the black and white block shape of the carrier object is cut from the intermediate image, the cut black and white block set is the second identification information, and when the second identification information is embedded, the second identification information may be embedded into the position of the black and white block set of the web page.

As shown in fig. 14, in step 1403, the second identification information is embedded in the carrier object.

Said embedding said second identification information into said carrier object comprises:

embedding the second identification information into a position of the first display element; or, the pseudo second identification information is embedded in an adjacent position of the first display element.

When the method is specifically implemented, the second identification information is embedded into the carrier object in various ways, and if an element matching the shape of the disguised element exists in the carrier object, the second identification information can be embedded into the position of the first display element, that is, the second identification information replaces the first display element matching the shape of the first display element, for example, if the second identification information is a dotted line containing the first identification information and the webpage has a dotted line, the second identification information can be embedded into the position of the dotted line on the webpage and the second identification information replaces the original dotted line (the first display element); or the second identification information may be embedded at an adjacent position to the first display element, for example, if the second identification information is a dotted line including the first identification information, and the dotted line (the first display element) exists in the web page, the second identification information may be embedded at an upper adjacent position or a lower adjacent position parallel to the dotted line on the web page.
