Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
Fig. 1 is a schematic structural diagram of an offline copyrighted content distribution system according to an embodiment of the present application.
As shown in fig. 1, the system 10 of the present embodiment includes: a platform side 11 and a user terminal 12.
The number of the user terminals 12 is plural, and 3 are taken as an example in fig. 1 and are respectively represented by a user a, a user B, and a user C.
The platform side 11 is configured to obtain the copyrighted content provided by the copyright side, and encrypt the copyrighted content to obtain an encrypted content.
The number of the user terminals 12 is plural, and at least one user terminal is used for downloading the encrypted content from the platform side, for example, user a downloads the encrypted content from the platform side; and at least one user terminal off-line propagates the encrypted content to other user terminals, for example, user a propagates the encrypted content to user B, and when playing the encrypted content, the user terminal sends an authentication request to the platform side when playing to the encryption point.
When at least one user terminal downloads the encrypted content from the platform side, for example, user a downloads the encrypted content from the platform side.
When at least one user terminal distributes the encrypted content, for example, the user A distributes the encrypted content to the user B. In addition, the encrypted content may be further distributed, for example, user B distributes the encrypted content to user C offline. In addition, the user terminal may be distributed to a plurality of user terminals when distributing the encrypted content, for example, user a distributes the encrypted content to user B and user D offline. The platform side 11 is further configured to: and after the authentication is passed, decrypting the encrypted content and allowing the user terminal to continuously play the decrypted content.
The platform side 11 is further configured to: performing three-party account distribution, wherein the three parties comprise: a copyright party, a platform party and a user party meeting preset conditions.
In some embodiments, the user terminal comprises: a network connection module to:
establishing network connection with a platform side, and downloading encrypted content from the platform side through the network connection; and/or the presence of a gas in the gas,
and when the encryption point is played, establishing network connection with the platform side, and disconnecting the network connection with the platform side at other time, wherein when the network connection is established with the platform side, the decryption key sent by the platform side is received through the network connection, and/or the transmission process information is sent to the platform side.
For example, for a user terminal downloading encrypted content from the platform side, the network connection module of the user terminal will establish a network connection with the platform side and download the encrypted content from the platform side.
For another example, if the user terminal is the encrypted content received from another user terminal, the network connection module of the user terminal may perform a transient network connection with the platform side, and obtain the decryption key through the network connection, so as to decrypt the encrypted content with the decryption key. Further, the transmission process information can be sent to the platform side.
The transmission procedure information includes, for example: the user ID of the distributor, the user ID of the receiver, the content ID of the distribution content, the device information of the user terminal used by the distributor, and the device information of the user terminal used by the receiver. The transmitting party is a user who transmits the encrypted content to other users, and the receiving party is a user who receives the encrypted content transmitted by other users.
Further, the user terminal sending the transmission process information may be a user terminal used by the transmitting party and/or a user terminal used by the receiving party.
In some embodiments, the user terminal does not need to access the internet when playing to the encryption point, and in this case, the number or letter of the decryption key can be obtained through a short message of a mobile phone or a voice service of a hotline phone, and then the number or letter is manually input into the APP of the user terminal to complete authentication; the APP of the user terminal can generate a string of number or letter codes (including transmission process information), the user sends the number or letter codes to a designated receiving number through short messages in a pasting and copying mode, the number or letter codes can also be orally transmitted to an operator through a hotline telephone, and then the short message receiving platform or the operator transmits the codes to the platform side, so that the platform side can construct a propagation chain of encrypted contents according to the transmission process information.
In some embodiments, the platform side comprises: a propagation process determination module to: and constructing a propagation process of the encrypted content.
Further, the propagation process determining module is specifically configured to:
recording user information corresponding to a user terminal downloading the encrypted content, receiving transmission process information sent by a user terminal not downloading the encrypted content, and constructing a complete chain of the transmission process according to the recorded user information and the received transmission process information; or,
and extracting the mark information from the encrypted content, and constructing a complete chain of the propagation process according to the mark information, wherein the propagation process information is recorded in the mark information of the encrypted content when the user terminal propagates the encrypted content to other user terminals.
For example, when the user a downloads the encrypted content, the platform side may record information of the user a, such as a user ID of the user a, and when the user a propagates the encrypted content to the user B, the user a records the propagation process, for example, when the propagator is the user a and the receiver is the user B, or the receiver performs the above-mentioned recording, for example, the user B records that the propagator is the user a and the receiver is the user B, and then, when any one of the user a and the user B is networked with the platform side, the recorded propagation information may be sent to the platform side, so that the platform side may determine that the user a propagates the encrypted content to the user B, and similarly, the platform side may also determine that the user B propagates the encrypted content to the user C, so that a complete chain of the propagation process of the user a, the user B, and the user C may be constructed.
For another example, the user terminal may further record the broadcast information in the encrypted content, for example, when the user a broadcasts to the user B, the user a records the transmission process information of the user a-the user B in the tag information portion of the encrypted content, and similarly, after the user B broadcasts the encrypted content, the user B may also record the user B-the user C in the tag information portion of the encrypted content, so that the platform side may construct a complete chain of the broadcast process of the user a-the user B-the user C according to the tag information of the encrypted content.
Further, the transmission process information may include, in addition to the user ID of the transmitting party and the user ID of the receiving party: content ID of the broadcast content, device information of the user terminal used by the broadcaster, device information of the user terminal used by the receiver, and the like.
Based on the complete chain of the propagation process constructed by the platform side, the user side meeting the conditions during the billing can be determined. For example, if the previous two levels of users of the current user are preset to participate in the billing, for example, the current user is user C, the complete chain in the propagation process is that user a propagates to user B, and user B propagates to user C, and the users who participate in user C and meet the preset conditions and pay by the users include: user a and user B. The preset conditions can be flexibly adjusted, the distribution levels participating in the distribution can be increased or decreased, and the distribution proportion of each distribution level can be adjusted.
In some embodiments, the user terminal comprises:
and the offline transmission module is used for establishing offline connection with other user terminals so as to transmit the encrypted content to other user terminals.
Further, the offline transmission module includes: the Bluetooth module, or, take the wifi module certainly.
When the decryption point is reached, establishing network connection with the platform side, and disconnecting the network connection with the platform side at other time;
receiving a decryption key sent by the platform side through the network connection, so as to decrypt encrypted content by using the decryption key, and/or transmitting transmission process information to the platform side, wherein the transmission process information includes: the user ID of the propagator, the user ID of the receiver, the content ID of the propagated content, the equipment information of the user terminal used by the propagator and the equipment information of the user terminal used by the receiver, so that the platform side determines the user side meeting the preset conditions according to the transmission process information.
The offline transmission module includes: the Bluetooth module, or, take the wifi module certainly.
In this embodiment, the user terminal performs transient networking with the platform side only when the encrypted content needs to be decrypted, and decrypts the encrypted content after acquiring the decryption key from the platform side. In addition, the user terminal can also send the transmission process information to the platform side during transient networking, so that the platform side can locate the propagation path of the encrypted content according to the transmission process information, and the user side and the like needing to be billed can be determined based on the propagation path.
In some embodiments, the platform side comprises:
and the recording module is used for recording the related information in the distribution process of the offline copyright content in the blockchain.
Taking the copyrighted content as an example of a video, the related information includes, for example, user information and video information, for example, user a downloads video 1, user a transmits video 1 to user B, user a pays for watching video 1, or directly transmits video to other users without watching, and so on.
Further, the platform side may further include:
the personalized processing module is used for performing personalized data processing, and the personalized data processing comprises one or more of the following items:
advertising; quantifying the advertisement putting effect; a directed offer; piracy monitoring;
counting the downloading amount and/or the propagation amount of the copyright content within a preset range and/or time, and dynamically rewarding a downloading party and/or a propagation party according to the downloading amount and/or the propagation amount;
obtaining the reward money provided by the initiator, determining the propagator between the initiator and the target according to the information recorded by the recording module, and sharing the reward money to the propagator between the initiator and the target according to a preset rule.
The data for performing the personalized data processing may be the above-mentioned related information recorded on the blockchain, and certainly is not limited to the information on the blockchain, and may also obtain the user data in other manners, and perform the personalized data processing based on the user data.
The dynamic rewarding refers to rewarding in different degrees according to different download amounts and/or propagation amounts, and in the following terms of loading capacity, generally speaking, the rewarding strength and the download amount are in an inverse relationship, that is, when the loading capacity is smaller, a larger rewarding strength is performed. For example, when the download amount in a certain area is less than 1 ten thousand, 100 tokens can be rewarded for the downloader, and when the download amount is between 1 ten thousand and 9 ten thousand, 50 tokens can be rewarded for the downloader, and so on, so that more download demands can be triggered when the download amount is smaller. For another example, the person who is participating in the distribution has incentive to be paid, and the distribution ratio may be dynamic, for example, when a new film is not yet famous, a user distributes the film, so that the distributor is awarded more TOKEN, and once the person who is participating in the distribution pays, the person who is participating in the distribution can obtain a larger ratio of distribution. When the popularity and the reputation of the part are improved, even people actively look for the part to see, the difficulty of spreading is small, and the reward can be reduced. Thus, dynamic rewards can also be awarded in the amount of spread.
In an oriented reward, for example, a woman's ball game fan wants to transmit her favorite video to a black star, she can buy a large TOKEN as a reward: if a day's video of her love is delivered to the ball star himself, then all people in this delivery chain share the TOKEN award. How to share can be set by a platform side, an uploader and the like. Similarly, video feeds for lost relatives, introspection for recruiting scarce talents, farm introductions for investments, can all be used to initiate directed video distribution using the above-described reward method.
Accordingly, based on the above system architecture, referring to fig. 2, an embodiment of the present application further provides an offline copyrighted content distribution method, including:
s21: the platform side acquires the copyright content provided by the copyright side and encrypts the copyright content to obtain encrypted content;
s22: at least one user terminal downloads encrypted content from a platform side, and the encrypted content is transmitted to other user terminals by the at least one user terminal in an off-line mode;
s23: when the user terminal plays the encrypted content and plays the encrypted content to an encryption point, an authentication request is sent to the platform side;
s24: after the platform side passes the authentication, decrypting the encrypted content and allowing the user terminal to continue playing the decrypted content;
s25: the platform side carries out three-party account distribution, and the three parties comprise: a copyright party, a platform party and a user party meeting preset conditions.
Among the above-mentioned contents, the copyrighted contents include, for example: video, audio, text, pictures, applications, web pages, etc.
With the increasing enhancement of intellectual property and copyright protection in various countries, video encryption processing is more necessary. The video encryption is to encrypt some copyrighted videos, and a user can obtain the watching right of the videos only under certain conditions. For example, the user can watch the video only by registering the account, and can watch the video for an unlimited number of times within a certain time or can watch the video for an unlimited number of times within a certain time, so that the interests of the video owner can be protected.
In this application, encryption is to encrypt the copyrighted content itself. Taking the copyright content as the video as an example, the encryption algorithm can adopt the existing video encryption algorithm and can also adopt the new video encryption algorithm provided by the application. Specific video encryption algorithms can be found in the following description.
At least one of the plurality of user terminals needs to be networked to the platform side to download the encrypted content from the platform side. For example, as shown in fig. 1, user a is networked with the platform side, and then user a may download encrypted content from the platform side, and user a and the platform side may be connected through a fixed network or a mobile network.
After at least one user terminal downloads the encrypted content from the platform side, the encrypted content may be transmitted in an offline manner at the user terminal, for example, user a transmits the encrypted content to user B offline. The offline transmission may be implemented by using any Device to Device (D2D) communication technology, such as bluetooth technology, wifi technology carried by the terminal, etc.
The user terminal downloads the encrypted video from the platform side, or can play the encrypted video after receiving the encrypted content transmitted by other user terminals. The encrypted content may include a free portion and a charged portion, and the free portion is played first when the encrypted content is played, so as to facilitate a user to try to see. When the encryption point is reached, the encryption part is entered, and if the user needs to continue watching, the user can pay for watching.
It should be noted that, when the user terminal plays the free part, any player may be used for playing, and when the encryption point is reached, if the player used by the user is a non-specific player, a prompt message may be popped up to prompt the user to download the specific player, and the specific player is used for subsequent playing.
