Having thus described the general principles of the present application, various non-limiting embodiments thereof will now be described in detail with reference to the accompanying drawings.

Example one

As shown in fig. 1, an embodiment of the present application provides a digital watermark-based creative work management method, where the method includes:

step S100: obtaining a first creative work;

step S200: obtaining basic information of the work according to the first creative work, wherein the basic information of the work comprises author information, content information and reading amount information;

specifically, the first creative work comprises work information needing creative protection and information identification, such as documents, multimedia and software, and the like, the first creative work is a digital carrier, watermark information is embedded into the digital carrier so as to be recognized and identified by a producer, the purposes of confirming content creators and purchasers, transmitting secret information or judging whether the carrier is tampered or not and the like can be achieved through the information hidden in the carrier, the use value of the original carrier is not influenced by the digital watermark, and the digital watermark is not easy to be detected and modified again, so that the first creative work is effectively protected. The basic information of the first work is author information, content information and reading amount information of the first creative work, and the content information comprises various parts of contents of the first creative work in different categories such as literature, industry, computers, teaching assistance and the like. Based on a big data information processing technology, the total reading data information of the first creative work on each platform and each channel and the basic information of authors, contents and the like can be obtained; based on the feature extraction and image recognition technology, the extraction of the work content can be realized. And further laying out the embedding scheme of the digital watermark based on the basic information of the work.

Step S300: obtaining a preset evaluation rule, wherein the preset evaluation rule corresponds to the basic information of the work;

specifically, the preset evaluation rule is determined according to the content and the reading amount of the work in the basic information of the work, and is an evaluation rule for the first creative work. The preset evaluation rules comprise content information division rules, reading amount information division rules and author ability division rules corresponding to different evaluation levels of the first creative work. The higher the evaluation level of the first creative work, the higher the requirement for basic information of the first creative work. Based on a big data information processing technology, reading data information of the first creative work, content grading information, author ability and experience information of the content information can be obtained, and then the first creative work is evaluated according to the preset evaluation rule.

Step S400: inputting the basic information of the work and the preset evaluation rule into an evaluation model to obtain a first evaluation result, wherein the first evaluation result comprises a plurality of evaluation values, and the plurality of evaluation values correspond to the basic information of the work;

specifically, the evaluation model is a neural network model, which is a complex network system formed by a large number of simple processing units (called neurons) widely connected with each other, reflects many basic features of human brain functions, and is a highly complex nonlinear dynamical learning system. The evaluation model processes the data by training and learning the input data and continuously learning and acquiring experience, so that the output information is more accurate. Inputting the basic information of the work and the preset evaluation rule as input data into the evaluation model to obtain a more accurate first evaluation result, wherein the first evaluation result comprises a plurality of evaluation values corresponding to the basic information of the work: the evaluation value of the author information, the evaluation value of the content information of each part of the first creative work, and the evaluation value of the reading amount information. And the accurate acquisition of the first evaluation result enables accurate calibration of the value of the first creative work and effective layout of the digital watermark.

Step S500: acquiring a watermark embedding scheme according to the evaluation value;

specifically, the watermark embedding scheme includes the type, size, density, embedding location, etc. of the embedded watermark for the first creative work. The larger the evaluation value is, the higher the embedding requirement of the first creative work on the digital watermark is, and the greater the number and the greater the density of the embedded watermarks of the core protection content of the first creative work are. Thus, after the evaluation value is determined, the content of the first creative work is further analyzed and evaluated, so that the position of the core content with the highest evaluation value of the first creative work is determined, and the watermark embedding scheme is further determined.

Step S600: acquiring work management information according to the first evaluation result and the watermark embedding scheme;

specifically, the work management information is the work management content matched with the first creative work according to the first evaluation result of the work and the watermark embedding scheme. The work management information includes reference authority management, download management, categorization, reference management, and the like for the first creative work. The first evaluation result corresponds to different work management schemes, the first creative work is matched with the corresponding work management scheme from the cloud database according to the first evaluation result grade, the higher the first evaluation result grade is, the stronger the requirements of information security protection, copyright protection and the like of the first creative work are, and the more complicated the management type of the work is. After the work management scheme is determined, management information for the first creative work is obtained according to the watermark embedding scheme. The extraction of the digital watermark information can be only extracted by an embedder or a person who grasps a specific extraction algorithm, and the safety of the algorithm is generally ensured by the complexity of the algorithm and the cryptography technology. Therefore, after the watermark is embedded, various management of the first creative work can be realized by extracting watermark information according to the work management information, and the protection level of the first creative work is improved by reasonably formulating a watermark embedding scheme and selecting an appropriate management scheme.

Step S700: obtaining a first work watermark according to the work management information and the first evaluation result, wherein the first work watermark comprises an identification mark, and the identification mark corresponds to the work management information;

step S800: and acquiring first execution information according to the first work watermark and the watermark embedding scheme, wherein the first execution information is used for embedding the first work watermark into the first creative work according to the watermark embedding scheme.

Specifically, the work management information and the first evaluation result determine the embedding location, identification and extraction functional requirements of the first work watermark, which in turn determines the first work watermark. The first work watermark comprises an identification mark capable of realizing the work management information, and data processing is carried out on the mark information by identifying the identification mark, so that the first creative work is classified, accessed, downloaded and other management contents. After determining the first work watermark, a system obtains the first execution information and executes a watermark embedding instruction, and embeds the first work watermark into the first creative work according to the watermark embedding scheme. Therefore, the watermark embedding scheme is determined by combining the product value, and the technical aims of finely managing the works and improving the protection of the digital watermark to the works are fulfilled.

Further, step S400 in the embodiment of the present application further includes:

step S410: obtaining a preset grading rule, wherein the preset grading rule has a first relation with the first evaluation result;

step S420: obtaining a first work grade according to the first evaluation result and the grade division rule;

step S430: linking the first creative work to a first level work library according to the first work level;

step S440: when the first work grade meets a first preset condition, obtaining a first associated work according to the work basic information and the first grade work library;

step S450: according to the first associated work and the first creative work, first work interlocking information is generated, and the first work interlocking information is added into the first creative work and the watermark of the first associated work, wherein the first work interlocking information comprises interlocking rules.

Specifically, the first creative work may be graded according to the preset grading rule. Works of different grades have different protection grades. Therefore, the first work grade of the first creative work is obtained according to the first evaluation result, and then the first creative work is linked to the work database at the same grade according to the first work grade so as to realize the unified protection and management of works at the same protection grade. The first preset condition is a work evaluation level threshold value needing a higher protection level, if the first work level meets the first preset condition, the stealing cost is improved and the safety risk of the first created work is reduced by obtaining work information with higher similarity with the first created work in the first-level work library, adding an interlocking watermark into the watermark information of the first created work through watermark interlocking.

Further, step S440 in the embodiment of the present application further includes:

step S441: obtaining an interlocking association requirement;

step S442: obtaining a first relevance threshold according to the interlocking relevance requirement;

step S443: obtaining first work information according to the first-level work library;

step S444: obtaining the first relevance according to the work basic information and the first work information;

step S445: judging whether the first relevance meets the first relevance threshold value;

step S446: when satisfied, the first work is taken as the first associated work.

Specifically, the interlocking association requirements need to be satisfied between the interlocked works, and the interlocking association requirements include: the authors of the interlocking works need to satisfy a certain relevance; the content needs to satisfy a certain relevance; the reading amount needs to satisfy a certain correlation. For example, two creations with the same author in the same domain and with click volumes at a higher threshold may be interlocked. The first relevance evaluation value between the two works is obtained by respectively obtaining basic data information of the first creative work and the first work information, so that whether the first creative work and the first work information can be interlocked or not is determined by judging whether the first relevance meets the first relevance threshold or not. And the interlocking works are screened according to the interlocking association requirement, so that the protection value of both sides of the interlocking works is higher.

Further, when there is no work meeting the first relevance threshold requirement in the first-level work library, step S445 in this embodiment of the present application further includes:

step S4451: obtaining a second work grade according to the first work grade, wherein the second work grade and the first work grade have a second relation;

step S4452: obtaining a second-grade work library according to the second work grade;

step S4453: obtaining second work information according to the second level work library;

step S4454: and when the first relevance between the second work information and the work basic information meets the first relevance threshold value, taking the second work information as the first relevant work.

Further, step S4451 in this embodiment of the present application further includes:

step S44511: judging whether the first work grade is a first grade, wherein the first grade is the highest grade;

step S44512: when the first work level is not a first level, the second work level is adjacent to and higher than the first work level;

step S44513: when the first work grade is the first grade, the second work grade is adjacent to the first work grade and lower than the first work grade.

Specifically, when the first-level works library does not have works meeting the requirement of the first relevance threshold, the system automatically searches the works in the works database higher than the first works level, and performs relevance analysis on the first works by obtaining basic information data of each work, so as to judge whether the relevance meets the first relevance threshold. The second work level is higher than the first work level. And if the first work grade is the highest grade, searching a work database with adjacent grades and smaller than the first work grade. And obtaining second work information of which the relevance with the first creative work meets the first relevance threshold value through searching and relevance analysis, and interlocking the second work information with the first creative work. By setting a more effective interlocking range, the protection range of the first creative work and each work in the work library is enlarged.

Further, step S500 in the embodiment of the present application further includes:

step S510: sorting according to the evaluation values to obtain a first evaluation value, wherein the first evaluation value is the evaluation value positioned at the top in the sorting from large to small;

step S520: obtaining first feature information according to the first evaluation value;

step S530: inputting the first characteristic information and the first creative work into a characteristic recognition model to obtain a first recognition result;

step S540: marking the first creative work according to the first identification result to obtain a first feature marking point;

step S550: acquiring a watermark embedding position according to the first characteristic marking point;

step S560: acquiring watermark embedding quantity according to the quantity of the first feature marking points;

step S570: and obtaining the watermark embedding scheme according to the watermark embedding position and the watermark embedding quantity.

Specifically, the evaluation values include evaluation values of various contents of the first creative work, evaluation levels, namely protection levels, of the contents of the parts in the first creative work are obtained through sorting, and then a watermark embedding scheme of the parts, including the number and density of watermark traps, is determined according to the protection levels of the parts. The first feature information is a feature of each part in the first creative work, and may be, for example, a title feature, an image feature, and the like. And the purpose of identifying the contents of each part is achieved by obtaining the first characteristic information. And inputting the first characteristic information and the first creative work into a characteristic identification model to obtain an identification result of the characteristic, and then carrying out characteristic marking on different parts of content according to the identification result, so that the watermark is accurately embedded according to a marking position. The first feature mark point can represent the position and embedding quantity of watermark embedding. Through feature extraction and marking, the intelligence and the high efficiency of watermark embedding are improved.

Further, step S700 in the embodiment of the present application further includes:

step S710: obtaining a first watermark level according to the first evaluation result;

step S720: acquiring management type watermark identification information according to the work management information;

step S730: and obtaining the first work watermark according to the management type watermark identification information and the first watermark level.

In particular, the higher the first watermark level, the higher the level of protection for the watermark embedding. Therefore, the watermark levels corresponding to the contents of the parts are obtained through the evaluation results of the parts of the first authored content, and the watermark information of the final contents of the parts is determined by combining the watermark identification characteristics of the management function in the work management information.

Further, step S600 in the embodiment of the present application further includes:

step S610: acquiring first management information according to the work management information;

step S620: acquiring a first management mark according to the first management information;

step S630: and extracting works through the first management mark to obtain a first marked work set, wherein the first marked work set comprises the first creative work.

Specifically, different management information corresponds to different management marks, the system identifies the first management mark to realize the management content at the mark, and the system identifies and extracts the work information containing the first management mark to realize the unified management of a certain management content. For example, if the work contains the 'non-reproducible' mark by identifying the watermark, the system extracts the mark to obtain the corresponding content of the work containing the mark; and through identifying and extracting the mark, a work information set containing the mark is obtained, so that the content which can not be copied in the set is consulted and managed in a unified way.

In summary, the method for managing an authored work based on a digital watermark provided by the embodiment of the present application has the following technical effects:

1. because a neural network model and a big data information processing technology are adopted, the content evaluation of each part of the first creative work is realized by acquiring each item of basic information data of the first creative work, so that different protection levels of each part of the work are determined according to the evaluation value, and a watermark embedding scheme of the first creative work is determined by combining the requirements of management information of the work. The watermark embedding layout is realized aiming at the works with different protection levels, so that the technical aim of further improving the protection of the digital watermark to the works is fulfilled.

Exemplary electronic device

The electronic device of the embodiment of the present application is described below with reference to fig. 3.

Fig. 3 illustrates a schematic structural diagram of an electronic device according to an embodiment of the present application.

Based on the inventive concept of the digital watermark-based creative work management method, the invention further provides a digital watermark-based creative work management system, on which a computer program is stored, and the program is executed by a processor to implement the steps of any one of the aforementioned digital watermark-based creative work management methods.

Where in fig. 3 a bus architecture (represented by bus 300), bus 300 may include any number of interconnected buses and bridges, bus 300 linking together various circuits including one or more processors, represented by processor 302, and memory, represented by memory 304. The bus 300 may also link together various other circuits such as peripherals, voltage regulators, power management circuits, and the like, which are well known in the art, and therefore, will not be described any further herein. A bus interface 305 provides an interface between the bus 300 and the receiver 301 and transmitter 303. The receiver 301 and the transmitter 303 may be the same element, i.e., a transceiver, providing a means for communicating with various other apparatus over a transmission medium.

The processor 302 is responsible for managing the bus 300 and general processing, and the memory 304 may be used for storing data used by the processor 302 in performing operations.

The application provides a digital watermark-based creative work management method, wherein the method comprises the following steps: obtaining a first creative work; obtaining basic information of the work according to the first creative work, wherein the basic information of the work comprises author information, content information and reading amount information; obtaining a preset evaluation rule, wherein the preset evaluation rule corresponds to the basic information of the work; inputting the basic information of the work and the preset evaluation rule into an evaluation model to obtain a first evaluation result, wherein the first evaluation result comprises a plurality of evaluation values, and the plurality of evaluation values correspond to the basic information of the work; acquiring a watermark embedding scheme according to the evaluation value; acquiring work management information according to the first evaluation result and the watermark embedding scheme; obtaining a first work watermark according to the work management information and the first evaluation result, wherein the first work watermark comprises an identification mark, and the identification mark corresponds to the work management information; and acquiring first execution information according to the first work watermark and the watermark embedding scheme, wherein the first execution information is used for embedding the first work watermark into the first creative work according to the watermark embedding scheme. The technical problems that in the prior art, the embedding mode of the digital watermark in the works is single, and the protection efficiency of the works is low are solved. The method and the device realize the value evaluation of the works based on the neural network model, thereby determining the watermark embedding scheme by combining the value of the works, and achieving the technical purposes of finely managing the works and improving the protection of the digital watermarks on the works.
