Based on this, the following describes in detail the information processing method based on web pages provided by the embodiment of the present application with reference to the information processing architecture in the embodiment of the present application shown in fig. 1.
In one or more possible embodiments, as shown in fig. 1, an information processing architecture proposed in an embodiment of the present application may include a server 10 and at least one client 11, where the at least one client 11 may include a user 1, a user 2, a user … …, and a user N, where N is an integer greater than 1. The server 10 provides data support for at least one client 11.
It should be noted that the server 10 in the embodiment of the present application may be applied to at least one of the following cloud platforms: the cloud platform comprises a public cloud, a private cloud, a proprietary cloud and a hybrid cloud, so that data support can be provided for at least one client corresponding to the server 10 through the server 10 on the cloud platform.
In an embodiment, the client 11 may provide a function of accessing a browser or an (Audio/video) Web player for a user, so that the user shares, uploads and browses multimedia through the browser or the Web player, and the server 10 may provide a data service for the browser or the Web player accessed by the client 11, where the browser or the Web player may include a Web Application Program Interface (Web Audio API). It should be noted that, the browser or the Web player including the Web Audio API provided in the embodiments of the present application has the characteristics of high compatibility, capability of carrying a large amount of information, flexible transmission content, and the like. Furthermore, the characteristic of high compatibility can be expressed in desktop end and mobile end browser environments compatible with the client, and the proportion of the compatible multi-class client can reach 97.36%. The characteristics of flexible transmission content and the like are represented in that the original multimedia information is not needed for subsequent information extraction, identification and tracing, and the normal playing and browsing of the original multimedia information can be ensured while the calculation amount is reduced. Therefore, the Web Audio API is suitable for the information processing method and the information tracing method based on the webpage in the embodiment of the application.
In addition, the Web player in the embodiment of the present application may further provide the information processing function and the information tracing function based on the Web page provided in the embodiment of the present application to the platform through a Web player Software Development Kit (SDK). Further, the server 10 implements the information processing function and the information tracing function provided in the embodiment of the present application through the SDK and a Web Audio API of a hypertext Markup Language (HTML 5).
It should be noted that, the multimedia information in the embodiment of the present application may include at least one of the following: video, audio-video, images carrying audio, text carrying audio.
The information processing method based on web pages provided by the embodiment of the present application is described in detail based on the information processing architecture shown in fig. 1. Here, taking a web player as an example for illustration, the functions and applications of the browser are the same as the functions and applications of the web player in the embodiment of the present application, and are not described herein again.
Based on this, the server 10 obtains a multimedia request sent by the client 11 of the web player, where the multimedia request includes multimedia information, and the multimedia request is used to prompt the server to perform at least one of the following operations: and releasing multimedia information and storing the multimedia information. Alternatively, the multimedia information may include information transmitted by the client 11, and may also include web page information provided by a web player.
The server 10 obtains the multimedia information uploaded by the client 11 from the multimedia request through the Web player SDK. The server 10 determines, according to the identity information of the client 11 and the multimedia information uploaded by the client 11, user information of the multimedia information and right information of the multimedia information, where the right information may be an enterprise or an individual, and determines the right information and the user information as authentication information. For example, when the client 11 is a client of the user a, the server 10 obtains the identity information of the user a through the Web player SDK, that is, the identity information of the user a may be determined as the user information, and the identity information of the user a and/or the source of the multimedia information may be determined as the right information. At this time, in one possible example, the using party information and the right party information may be the same user or business.
And then, converting the authentication information through the Web Audio API according to a first preset conversion condition to obtain an Audio digital watermark, and performing watermark embedding processing on the multimedia information uploaded by the client 11 according to the Audio digital watermark to obtain the authentication multimedia information embedded with the Audio digital watermark.
Therefore, when the server receives the multimedia information uploaded by the client, the authentication information of the copyright content containing the multimedia information is converted into the audio digital watermark, and the audio digital watermark is embedded into the multimedia information in real time, so that huge cost burden caused by cloud transcoding is avoided, and transcoding cost is reduced. And because the embodiment of the application embeds the Audio digital watermark into the multimedia information in real time through the Web Audio API when the Web player receives the multimedia information uploaded by the client, the authentication multimedia information embedded with the Audio digital watermark is obtained, transcoding processing is not needed to be carried out at other cloud ends in the later period, and the authentication multimedia information is conveniently distributed to other platforms, so that the method and the device are suitable for a large number of scenes distributed and played by the client.
In another or multiple possible embodiments, as shown in fig. 2, the webpage-based information processing method provided by the embodiment of the present application may be applied to a scenario in which audio digital watermarks are customized for some specific user groups.
Based on this, at least one client 11 in the information processing architecture proposed in the embodiment of the present application may include a group 1, a group 2, … …, and a group M, where M is an integer greater than 1.
As shown in fig. 2, still taking a web player as an example for illustration, the server 10 obtains multimedia information uploaded by the user B of the web player. The server 10 obtains the multimedia information uploaded by the user B from the Web player SDK, and determines the group to which the user B belongs based on the identity information of the user B.
If the user B belongs to the group 1, since the user B belongs to the group 1, the user side information of the group 1 may be determined as the user side information of the user B. When the right side detecting the multimedia information also belongs to the group 1, the audio digital watermark 1 pre-stored in the group 1 and specific to the group 1 can be determined as the audio digital watermark of the user B, wherein the audio digital watermark 1 is determined by the use side information and the right side information of the group 1.
Then, the server 10 performs watermark embedding processing on the multimedia information uploaded by the user B according to the Audio digital watermark 1 through the Web Audio API, so as to obtain authenticated multimedia information embedded with the Audio digital watermark 1.
Therefore, in the scene of customizing the audio digital watermarks for some special user groups, the group to which the user belongs is determined based on the identity information of the user, the watermark embedding processing is carried out on the multimedia information according to the pre-stored group and the specific audio digital watermarks, and the authentication multimedia information embedded with the audio digital watermarks is obtained, so that the audio digital watermarks cannot be separated from the original multimedia information, and the audio digital watermarks can be used for tracing the streaming channel of the stolen multimedia information in the scene of pirating the authentication multimedia information in the modes of malicious user screen shooting, screen recording and the like.
Based on this, the server 10 in this embodiment of the present application may provide a function of performing copyright tracing on the multimedia information for the client (e.g., the client corresponding to the right party information and the client corresponding to the user party information) in addition to generating the authentication multimedia information, and may specifically be described in detail with reference to the architecture shown in fig. 1 or fig. 2.
As shown in fig. 1 or fig. 2, the server 10 receives a multimedia information tracing request initiated by a client, and the client may include a client 11 uploading original multimedia information and a client corresponding to rights party information.
Then, the server 10 obtains the first multimedia information according to the multimedia information identifier in the multimedia information tracing request, and extracts the first authentication information in the first multimedia information, where the first authentication information includes the right party information and the user party information of the target multimedia information.
Then, the server 10 traces back the copyright information of the target multimedia information based on the right side information and the user side information of the target multimedia information.
Therefore, the server can receive a multimedia information tracing request initiated by the client, and extract the rights party information and the user party information in the first multimedia information corresponding to the multimedia information identification according to the multimedia information identification in the multimedia information tracing request, so as to trace the copyright information of the target multimedia information.
It should be noted that the server 10 in the embodiment of the present application may be applied to any scene in which watermark embedding processing and copyright tracing are performed on multimedia information, for example, may be applied to at least one cloud platform of a public cloud, a private cloud, a proprietary cloud, and a hybrid cloud, and may trace an audio/video streaming channel from a stolen audio/video.
According to the above architecture and application scenario, the following describes in detail the information processing method based on web pages provided by the embodiment of the present application with reference to fig. 3.
FIG. 3 is a flow diagram illustrating a method for web-based information processing according to one embodiment.
As shown in fig. 3, the information processing method based on the web page may be applied to a server, and specifically may include:
The above steps are described in detail below, specifically as follows.
Referring to step 310, in a possible example, step 310 may specifically include:
and acquiring multimedia information of the authentication information to be embedded and the authentication information to be embedded in the browser webpage.
Illustratively, multimedia information to be embedded with authentication information uploaded by a user is acquired through a browser webpage (or a Web player webpage), and according to identity information of a user client and the multimedia information uploaded by the user, user side information of the multimedia information and right side information of the multimedia information are determined, and the right side information and the user side information are determined as the authentication information.
In one example, multimedia information to be embedded with authentication information uploaded by a client user is obtained, and the authentication information is determined according to user Identity information and the multimedia information uploaded by the user, where the authentication information includes rights side information and users side information of the multimedia information, and the user Identity information may be identification Information (ID) of the client.
Referring to step 320, the authentication information to be embedded, which is obtained in step 310, may be converted according to a first preset conversion condition to obtain the audio digital watermark, where the first preset conversion condition may be set by a user according to experience and actual needs.
Based on this, in one or more possible examples, the first preset conversion condition includes binary conversion processing as an example, and as shown in fig. 4, step 320 in the embodiment of the present application may specifically include step 3201 to step 3203.
Here, the preset Audio frequency may be a specific frequency arbitrarily set by a user, and specifically, the conversion to the Audio digital watermark having the preset Audio frequency may be implemented by an Oscillator (Oscillator Node) in the Web Audio API.
Illustratively, the authentication information is binary-converted by using a binary conversion algorithm, so as to obtain the authentication information with a binary value. Then, the binarized authentication information is converted into a group of frequency values which are relatively insensitive to human ears, such as 25/50/75 hertz (Hz), and the audio digital watermark of pure tone of 0/1 values after the binarization of the authentication information can be loudness distinguished by adjusting an oscillator, wherein the loudness is set to 0 when meeting 0, the normal loudness is kept when meeting 1, and the duration of each bit of information is respectively 50 milliseconds (ms).
Therefore, when the authentication information is converted into the audio digital watermark, the authentication information is converted into the binary authentication information, so that the subsequent conversion of the audio digital watermark is facilitated. The binary authentication information is converted into the audio digital watermark with specific frequency through the preset oscillator, so that the audio digital watermark can be embedded in the multimedia information playing process conveniently.
The following describes each of steps 3201 to 3202 in detail.
In one or more possible examples, the authentication information further includes a separation identifier, and the separation identifier is used to distinguish the right party information and the user party information, based on which the step 3201 specifically includes:
and carrying out binary conversion processing on the separation mark to obtain a binary separation mark.
Illustratively, the authentication information and the separation identifier are simultaneously subjected to binary conversion processing to obtain binary values of the authentication information and the separation identifier, so that the right side information and the user side information in the authentication information can be distinguished conveniently.
Based on the binary authentication information and the separation identification, the audio digital watermark is obtained, and the audio digital watermark comprises the authentication information and the separation identification.
In one or more possible examples, before step 3202, the web-based information processing method may further include:
according to the binarized authentication information, at least one oscillator corresponding to the authentication information is constructed, the audio frequency generated by each oscillator in the at least one oscillator is different, and the frequency value of the audio frequency generated by each oscillator is equal to a preset frequency value; determining that a first oscillator of the at least one oscillator is a preset oscillator.
Here, the first oscillator may be any one of at least one oscillator. The frequency value of the audio frequency generated by each oscillator may be less than or equal to a preset frequency value.
Based on this, step 3202 may specifically include:
and each oscillator generates an audio digital watermark with a preset audio frequency corresponding to each oscillator according to the binary authentication information.
Here, the preset frequency value may be a frequency value determined by an audio frequency received by the human ear credential.
Illustratively, a plurality of oscillators corresponding to the authentication information are constructed by using a preset algorithm in the Web Audio API, such as audiocontext, createoscillator (), Audio frequencies generated by each oscillator in the plurality of oscillators are different, in order to prevent loss of some frequencies in the pirated Audio compression process, a group of frequency values less sensitive to human ears, such as 25/50/75Hz, is selected, and each oscillator generates an Audio digital watermark in a form of a polyphone with the Audio frequency corresponding to each oscillator according to the binarized authentication information.
Therefore, when the authentication information is converted into the audio digital watermark, at least one oscillator with different audio frequencies corresponding to the authentication information is constructed according to the binary authentication information, then, the first oscillator in the at least one oscillator is determined to be a preset oscillator, the audio frequency generated by each oscillator is a frequency value which is relatively insensitive to human ears, the concealment is high, the audio digital watermark is concealed in the original audio playing process by using the masking effect of sound, an attacker is difficult to find, and the loss of certain frequencies in the pirated audio compression process can be effectively prevented.
Referring to step 330, in a possible example, step 330 may specifically include:
and carrying out watermark embedding processing on the multimedia information based on the audio digital watermark through a webpage player interface in the browser to obtain the authentication multimedia information embedded with the audio digital watermark.
In one or more possible examples, step 330 may specifically include:
and embedding the audio digital watermark into the multimedia information through a watermark embedding algorithm to obtain the authentication multimedia information.
Illustratively, the watermark embedding algorithm may be an audio digital watermark algorithm, the multimedia information is an audio/video file, and based on this, the audio digital watermark is embedded into the audio/video file through the watermark embedding algorithm, so as to obtain the audio/video file in a format such as wav, mp3, avi, and the like.
Thus, under the condition of obtaining the authentication multimedia information, when a user records and captures a screen, the audio digital watermark exists in the envelope of the original media information. Due to the masking characteristic of the auditory system, the perceptibility of the audio watermark by the user is very low, and the embedding process of the watermark has no great influence on the original tone quality of the audio file of the multimedia information or the influence cannot be felt by human ears.
Therefore, the audio digital watermark is embedded into the multimedia information through the watermark embedding algorithm to obtain the authentication multimedia information, and therefore the probability that the audio digital watermark is discovered and attacked by a malicious user can be reduced on the premise that the hearing experience of the user is not influenced.
In one or more possible examples, the multimedia information has a duration that is the same as a duration of the audio digital watermark.
Illustratively, when a user performs operations of capturing and recording the pirated multimedia information, the audio digital watermark and the multimedia information are recorded together, and the duration of the multimedia information is the same as that of the audio digital watermark, so that the malicious deletion of the copyright statement segment of the multimedia information can be avoided, for example, the malicious user is prevented from intentionally deleting the copyright statement segment at the head and the tail of the audio/video film for pirating.
In one or more possible examples, the web-based information processing method may further include:
acquiring an audio node for playing multimedia information and a target oscillator for generating an audio digital watermark; determining a loudspeaker according to the audio node and the target oscillator; and playing the authenticated multimedia information through a loudspeaker.
Here, the target oscillator may be any one of the above-described at least one oscillator.
