Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order; furthermore, the embodiments and features of the embodiments in the present disclosure may be arbitrarily combined with each other without conflict.
In which the terminology used in the embodiments of the disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in the disclosed embodiments and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In the following description, suffixes such as "module", "part", or "unit" used to denote elements are used only for the convenience of explanation of the present disclosure, and have no specific meaning by themselves. Thus, "module", "component" or "unit" may be used mixedly.
In the related art, the entire fee is charged once for each on-demand, which is unfair to the user who needs to terminate watching for only a certain period of time. Some video service providers have established a pay-per-demand policy of: the first 5 minutes are free, and more than 5 minutes are charged. The common practice in this case is to stop playing from 5 minutes to zero and 1 second, and prompt the user to pay, and the user can continue playing after paying, and this case collects all the fees once; some video service providers also specify policies such as: the first 5 minutes are free, only half the fee is charged for 5 to 10 minutes, more than 10 minutes is charged in full, and the current approach implements a half-way termination only partial or free, which can cause unnecessary trouble due to lack of mutual trust between the two parties. But this would lead to billing disputes between the user and the video service provider if it is necessary to stop playing the video and ask the user if he continues to play, both 5 minutes and 10 minutes (if there are more tiered billing policies), otherwise due to the unreliability of the network transmission.
In order to solve the above problems, in the embodiment of the present disclosure, by setting a payment transaction, the video watching duration of a user is calculated in real time by using a block chain technology and an intelligent contract technology, and a video node obtains a payment amount based on the actual video watching duration of the user, so that the user can pay for a single-time on-demand program according to the actual watching duration, thereby solving the unfair problem that the user only watches part of video content but needs to pay for the full charge of watching the video, and effectively improving the video watching experience of the user.
Referring to fig. 1, fig. 1 is a schematic flowchart illustrating a block chain based video payment method according to an embodiment of the present disclosure, where the method includes steps S101 to S103.
In step S101, the video node sets up a first payment transaction based on the smart contract.
Specifically, the user U enters into a smart contract with the video service provider P, and the video node (i.e., the video service provider node) sets a first payment transaction through the smart contract, the first payment transaction indicating payment rules of the user node, which may include payment calculation rules based on the video viewing time and the calculation time thereof. For example, after the user actually watches the video, the actual payment amount and the payment time point are calculated according to the actual watching duration of the user based on the first payment transaction, wherein the first payment transaction may include a step function calculated with respect to the payment amount, so that the step charging according to the actual watching duration of the video by the user is realized.
In step S102, after the user node watches the video based on the smart contract, the video node calculates the payment amount and the payment time point that the user node needs to pay based on the watching duration of the user node based on the first payment transaction, and sends the payment amount and the payment time point to the user node, so that the user node generates a second payment transaction based on the payment amount and the payment time point that the user node needs to pay based on the watching duration of the user node, signs the second payment transaction, and returns the second payment transaction to the video node.
In this embodiment, by using the synchronicity and tamper resistance of the data of the block link and the payment amount and payment time calculated based on the actual viewing time of the user, the charging dispute between the user and the video service provider caused by the unreliability of network transmission in the related art can be effectively solved. The payment amount is the amount of the user node paying to the video node, and the payment time point is the time point at which the video node acquires the payment amount of the user node. The effect of calculating the payment time point while calculating the payment amount includes that the user may pause playing the video for reasons other than closing the video when watching the video, and the payment of the user node and the charging of the video node are realized at a specific time point, which can be traced back as evidence for disputes of subsequent video parties and user parties about video payment.
In this embodiment, the first payment transaction includes a payment calculation rule based on the video viewing duration. In this embodiment, the payment calculation is performed by playing the video every preset time period, and when the user terminates watching the video, the user charges the video directly based on the actual watching time length, where the step S102 specifically includes the following steps:
after the video is played, the video node calculates payment amount required to be paid by the user node based on the watching time generated at intervals of a preset time period and corresponding payment time points at intervals of a preset time period according to the payment calculation rule; and the number of the first and second groups,
the video node selects the payment amount with the longest viewing time and the corresponding payment time point from the payment amount and the payment time point which are calculated every other preset time period and need to be paid for the viewing time as the payment amount and the payment time point which need to be paid for the user node based on the viewing time. In addition, by selecting the calculation result with the longest duration, the present embodiment can also avoid the problem that when some users watch the video, the watching of the video needs to be suspended for some reasons in the middle, and the watching of the video continues to be continued, which may cause the system to repeatedly charge the users. .
It should be noted that, a person skilled in the art may adaptively set the preset time period according to the actual situation, and the payment amount and the time point thereof are calculated every other preset time period in the video playing, for example, the payment amount and the payment time point are calculated every 5 minutes in the video playing.
According to the charging mode for watching the video by the user, the charging can be carried out according to the actual watching duration of the user, meanwhile, the problem that the user watches the same video for repeated charging can be effectively avoided, and the video watching experience of the user is effectively improved.
In step S103, the video node broadcasts a second payment transaction signed by the user node into the blockchain.
It will be appreciated that the video node broadcasts a second payment transaction into the blockchain, which second payment transaction is effected.
In step S104, the video node obtains, at the payment time point, a payment amount paid by the user node based on the viewing duration thereof, based on the second payment transaction signed by the user node.
Specifically, the video node and the user node may create a common account based on an intelligent contract, the user deposits a preset amount (may be an amount for viewing a complete video) in the common account before viewing the video, and when the payment time point is reached, the video node directly obtains the payment amount of the user node based on the viewing duration of the user node from the common account.
Referring to fig. 2, fig. 2 is a schematic flow chart of a video payment method based on a block chain according to a second embodiment of the present disclosure, in the first embodiment, by setting a collection transaction and a common account, a user node deposits a prepaid fee into the common account through the collection transaction, and when a payment condition is met, a video party is ensured to obtain a payment amount from the common account in the form of an intelligent contract, and the method further includes step S201, and step S104 is further divided into step S104 a.
In step S201, the video node sets a collection transaction and a common account based on the intelligent contract, where the collection transaction is used to instruct the video node to obtain a payment amount paid by the user node from the common account, and the user node prestores a preset amount to the common account before viewing a video based on the intelligent contract;
in step S104a, the video node obtains, from the common account at the payment time point, a payment amount paid by the user node based on the viewing duration thereof, based on the payment transaction and a second payment transaction signed by the user node.
Further, the collection transaction may be used to instruct the user node to obtain a remaining amount from the common account, where the remaining amount is a difference between the preset amount and the payment amount.
Referring to fig. 3, fig. 3 is a schematic flowchart of a video payment method based on a block chain according to a third embodiment of the present disclosure, in which a second payment transaction is signed by a video node and a user node and broadcast in the block chain, the transaction is validated to ensure that both rights and interests of the user node and the video node are not impaired, specifically, step S103 is further divided into steps S103a and S103b, and step S104 is further divided into step S104 b.
In step S103a, the video node adds a signature to the second payment transaction signed by the user node;
in step S103b, the video node broadcasts the additionally signed second payment transaction into a blockchain;
in step S105b, the video node acquires, at the payment time point, a payment amount paid by the user node based on the viewing duration thereof, based on the additionally signed second payment transaction;
to further understand the disclosure, the present embodiment further explains in conjunction with the above embodiments that the user U and the video service provider P set up a pre-payment transaction (i.e., a collection transaction) and a formal payment transaction (i.e., a first payment transaction and a second payment transaction generated based on the first payment transaction) through a smart contract. And the U sends an updated formal payment transaction to the P every time the U receives the program for a certain time. P broadcasts the official transaction to the blockchain after the appointed time to obtain payment for U.
Intelligent contract:
(1) u requests video from P
(2) P sets transaction Tprecharge{[IU]，[o＝c→(U，P)]}
(3) P sets transaction Tcharge{[o]，[f(n)→P，(c-f(n))→U]|[g(N，n)]}
(4) P to TprechargeAnd TchargeSignature is sent to U
(5) U to TprechargePost-signature broadcast to blockchains
(6) P-to-U video streaming
(7) The following procedure is performed
1.n＝0
Do in while video playing
3. Waiting for a period of time m
4.n＝n+1
U modifies Tcharge according to n value, signature is sent to P
6.end while
(8) After g (N, N), P additionally signs Tcharge with the maximum f (N) value and broadcasts the added signature to the block chain
In the above intelligent contract, it is explained that:
(A) p represents a video website or service provider providing a video service. U represents a user who views a program. [ IU ] represents the own funds from U for c in the transaction Tprefix, which may be in real currency or virtual currency. c → (U, P) indicates that funds in the amount c are paid to an account that is co-managed by U and P, and the funds can only be used if both U and P agree. [ o ═ c → (U, P) ] represents a fund pool formed by o marks c → (U, P). [ o ] indicates that the funds in Tcharge originate from c → (U, P).
(B) f (n) → P, (c-f (n) → U, and f (n) represent funds in the amount of f (n) to be paid out to P, while remaining funds are returned to U. Where n is the actual viewing time of U, which is generally in units of 1 minute, but may be in units of other time lengths, such as every 15 seconds or other real-time units. If m in 1 minute unit (7) is 1 minute, and if m in 15 seconds is 15 seconds, m in 7 is 15 seconds. And f (n) is a function of n and represents the calculated cost of U due to n. If f (n) is a step function, then P can implement a step charge for U.
(C)[g(N，n)]Is a transaction TchargeAn additional condition is established, and the combined use of |' and transaction contents [ f (n)) → P, (c-f (n)) → U]The phases are separated. Indicating that the transaction is established only after time g (N, N) is reached. Due to TchargeIs a transaction between U and P, so TchargeThe satisfied condition requires that time g (N, N) be reached in addition to the signature of U and P. N represents the duration of the film. g (N, N) is a function of the duration of the film and the duration of the user's viewing, representingAnd calculating the time point of the final charge according to the film time length and the actual watching time length of the user.
(D) When the user starts to watch the video, the value of n increases by 1 every one time unit.
(E) Since the blockchain system allows only one of the transactions to be validated for transactions using the same fund pool, although P will get multiple T with U signaturechargeTransactions, but only one of them can be validated. Therefore, P selects T with the largest f (n) valuechargeThe additional signature is broadcast to the blockchain. According to the above intelligent contract, the present embodiment further describes:
(1) the timing unit m is 1 minute, i.e. the value of n increases by 1 every 1 minute. The film time N is 100 minutes. The full amount of the film is due for 5 yuan.
(2) f (n) is a step function, f (n) is 0 when n is less than or equal to 5, f (n) is 5 × 10 when 5< n is less than or equal to 10, f (n) is 5 × 30 when 10< n is less than or equal to 20, and f (n) is 5 when n is greater than 20. I.e., free for the first 5 minutes, full 10% for 5 to 10 minutes, full 30% for 10 to 20 minutes, and full over 20 minutes.
(3) g (N, N) is a discrete function, and when N < N, g (N) is N + 5; when N is equal to or greater than N, g (N, N) ═ N + 1.
(4) If the user watches 8 minutes, i.e. terminates watching, then after 5 minutes, i.e. 13 minutes, the user is automatically charged 0.5 dollars and the user is automatically returned 4.5 dollars.
(5) If the user watches 18 minutes, i.e. terminates watching, then after 5 minutes, i.e. 23 minutes, the user is automatically charged 1.5 dollars and the user is automatically returned 3.5 dollars.
(6) If the user finishes watching for 28 minutes, i.e. terminates watching, the user will be automatically charged 5 yuan after 5 minutes, i.e. 33 minutes.
(7) If the user watched the entire movie in its entirety, the user would be automatically collected 5 dollars at the 101 st minute.
Therefore, in the above process, the user is not prompted to continue to pay or is asked whether to continue watching, that is, the video playing is interrupted or the user experience is affected by covering a layer of semi-transparent page on the video program.
