Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the following detailed description of the specific embodiments of the present disclosure will be given with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the disclosure, are not intended to limit the disclosure.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and the above-described figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order; moreover, embodiments of the present disclosure and features of embodiments may be arbitrarily combined with each other without conflict.
Wherein 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 this disclosure 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", "component", or "unit" for representing elements are used only for facilitating the description of the present disclosure, and are not of specific significance per se. Thus, "module," "component," or "unit" may be used in combination.
In the related art, the pay-per-view is charged all at once, which is unfair to users who need to stop watching only for a certain period of time. Some video service providers formulate pay-per-order policies that are: 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 for 1 second, and prompt the user to pay, and the user can continue playing after paying, and this case has all the fees charged once; still other video service providers specify policies such as: the first 5 minutes are free, the 5 to 10 minutes only charge half the fee, and the full charge exceeds 10 minutes, and the current mode realizes the mode that the half way is terminated only partially or is free, and the two parties lack mutual trust, thus causing unnecessary trouble. But this would result in a billing dispute between the user and the video service provider if the video needs to be stopped and the user is asked if it continues to play at both the 5 minute and 10 minute intervals (if there are more stepped billing policies).
In order to solve the problems, the embodiment of the disclosure utilizes the blockchain technology and the intelligent contract technology, calculates the video viewing time of the user in real time by setting payment transaction, and the video node obtains the payment amount based on the actual video viewing time of the user, so that the user can pay for the program on demand at a time according to the actual viewing time, thereby solving the problems of unfairness and the like caused by that the user only views part of video content but needs to pay the full charge of viewing the video, and effectively improving the video viewing experience of the user.
Referring to fig. 1, fig. 1 is a flowchart of a video payment method based on blockchain according to an embodiment of the disclosure, and the method includes steps S101-S103.
In step S101, the video node sets a first payment transaction based on the smart contract.
Specifically, the user U makes an intelligent 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 intelligent contract, the first payment transaction being used to indicate a payment rule of the user node, the payment rule may include a payment calculation rule based on a video viewing duration and a calculation time thereof. For example, after the user actually views the video, an actual payment amount and a payment time point are calculated according to the actual viewing time length 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 as to implement step charging according to the actual viewing time length of the video.
In step S102, after the user node views the video based on the smart contract, the video node calculates a payment amount and a payment time point that the user node needs to pay based on the viewing time length 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 viewing time length, signs the second payment transaction, and returns the second payment transaction to the video node.
In this embodiment, the synchronicity and tamper resistance of the blockchain data are utilized, and the payment amount and payment time point calculated based on the actual viewing time of the user can effectively solve the billing dispute between the user and the video service provider caused by the unreliability of network transmission in the related art. The payment amount is the amount of the user node needing to pay to the video node, and the payment time point is that the video node obtains the payment amount of the user node at the time point. The effect of the present embodiment that the payment amount needs to be calculated at the same time includes that the user may pause playing the video for other reasons than closing the video while 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 used as evidence to trace the disputes of the follow-up video party and the user party about the video payment.
In this embodiment, the first payment transaction includes payment calculation rules based on a video viewing duration. When the user views the video, he may feel that the video is not expected to be viewed again after watching for several minutes, and the user wants to stop viewing the video in mid-way, in this embodiment, pay calculation is performed by playing the video every preset time period, and when the user stops viewing the video, the user directly charges for the video based on the actual viewing time period, and the step S102 specifically includes the following steps:
the video node calculates payment amount to be paid by the user node based on the watching duration generated at intervals of preset time periods and corresponding payment time points according to the payment calculation rule at intervals of preset time periods after the video is played; the method comprises the steps of,
the video node selects the payment amount with the longest viewing duration and the corresponding payment time point from the payment amount and the payment time point which are calculated based on the viewing duration and obtained every preset time period, and the payment amount and the payment time point which are calculated based on the viewing duration and obtained by the video node are used as the payment amount and the payment time point which are required to be paid by the user node. In addition, by selecting the calculation result with the longest duration, the embodiment can also avoid that some users need to pause watching the video for some reasons in the middle when watching the video, and the problem that the system charges the users repeatedly is likely to exist when the video is continuously watched. .
It should be noted that, a person skilled in the art may adaptively set a preset time period according to an actual situation, and calculate the payment amount and the time point of the payment every other preset time period by the video playing, for example, calculate the payment amount and the payment time point every 5 minutes by the video playing.
According to the charging mode of watching the video by the user, the charging can be performed according to the actual watching duration of the user, meanwhile, the problem that the user watches the same video to perform 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, the second payment transaction being in effect.
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 a second payment transaction signed by the user node.
Specifically, the video node and the user node may create a shared account based on the intelligent contract, the user first deposits a preset amount (may be the amount of watching the complete video) in the shared account before watching 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 watching time period from the shared account, in some embodiments, when the user only watches a part of the video, that is, under the condition that the complete video amount is not reached, the video node obtains the payment amount of the user from the shared account, and at the same time, the user node obtains the remaining funds from the shared account, based on the manner, the video party and the user party can timely obtain the funds and refund the funds, thereby further improving the user video watching experience, and simultaneously facilitating the funds management of the video party.
Referring to fig. 2, fig. 2 is a flowchart of a video payment method based on a blockchain provided in a second embodiment of the present disclosure, in which, based on the first embodiment, a user node stores a prepayment into a common account through a collection transaction and the common account, and when a payment condition is reached, a video party is ensured to obtain a payment amount from the common account in the form of an intelligent contract, the method further includes step S201, and step S104 is further divided into step S104a.
In step S201, the video node sets a collection transaction and a shared account based on the smart contract, the collection transaction being used to instruct the video node to obtain a payment amount paid by the user node from the shared account, and the user node pre-stores a preset amount to the shared account before viewing video based on the smart contract;
in step S104a, the video node obtains a payment amount paid by a user node based on its viewing duration from the shared account at the payment time point based on the collection transaction and a second payment transaction signed by the user node.
Further, the collection transaction may be further configured to instruct the user node to obtain a remaining amount from the shared account, wherein the remaining amount is a difference between the preset amount and the payment amount.
Referring to fig. 3, fig. 3 is a flowchart of a video payment method based on a blockchain provided in a third embodiment of the present disclosure, on the basis of the first embodiment, a second payment transaction is signed by a video node and a user node and broadcasted in the blockchain, the transaction is validated to ensure that rights of both the user node and the video node are not damaged, specifically, step S103 is further divided into steps S103a and S103b, and step S104 is further divided into step S104b.
In step S103a, the video node appends a signature to a 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 obtains, 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;
for further understanding of the present disclosure, this embodiment is further described in connection with the above-described embodiments, in which the user U sets 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 an intelligent contract with the video service provider P. And after receiving the program for a certain time, the U sends an updated formal payment transaction to the P. P broadcasts a formal transaction to the blockchain after the agreed time to obtain payment for U.
Intelligent contract:
(1) U requests video from P
(2) P set transaction T precharge {[I U ]，[o＝c→(U，P)]}
(3) P set transaction T charge {[o]，[f(n)→P，(c-f(n))→U]|[g(N，n)]}
(4) P to T precharge And T charge Signature and issue to U
(5) U is opposite to T precharge Signed broadcast to blockchain
(6) P sending video stream to U
(7) The following procedure is performed
1.n＝0
Do in white video playback
3. Waiting for a period of length m
4.n＝n+1
5.U modifying Tcharge according to n value, signature to P
6.end while
(8) After g (N, N), the Tcharge with the largest value of P to f (N) is broadcast to the blockchain
In the above intelligent contracts, description is made:
(A) P represents a video website or service provider that provides video services. U represents the user viewing the program. [ IU ] represents the owned funds from U for c in the transaction Tpayy, which may be either real currency or virtual currency. c→ (U, P) means that funds of amount c are paid to the account co-administered by U and P, which funds can only be used if both U and P agree. [ o=c→ (U, P) ] represents a pool of funds formed by the o-label c→ (U, P). [ o ] represents that the funds in Tcharge originate from c.fwdarw. (U, P).
(B) f (n) →p, (c-f (n))→u means that funds of the amount f (n) are paid to P while the remaining funds are returned to U. Where n is the length of time that the U actually views, typically in 1 minute, although other time lengths may be used, such as other time units such as every 15 seconds. If m in 1 minute is 1 minute, m in 7 is 15 seconds, and if m in 15 seconds is 1 minute. f (n) is then a function of n, indicating the cost to be paid by U calculated from n. If f (n) is a step function, P may implement a step charge for U.
(C)[g(N，n)]Is transaction T charge The additional condition that is satisfied is combined with the transaction content [ f (n) →P, (c-f (n))→U]Separated from each other. Indicating that the transaction is not valid until the time of g (N, N) is reached. Due to T charge Is a transaction of both U and P, thus T charge The conditions to be satisfied are that the signatures of both U and P are provided, and that the time of g (N, N) is reached. N represents the duration of the film. g (N, N) is a function of the film duration and the user viewing duration, representing the point in time of the final charge calculated from the film duration and the user actual viewing duration.
(D) When the user starts watching the video, the value of n is increased by 1 every one timing unit.
(E) Since the blockchain system allows only one to be validated for transactions using the same pool of funds, although P will get multiple T with U-signatures charge The transaction, but only one of them can take effect. Therefore P will select T with the largest f (n) value charge The appended signature is broadcast to the blockchain.
According to the above intelligent contract, this embodiment is further described as follows:
(1) The timing unit m is 1 minute, i.e. the n value increases by 1 every 1 minute elapsed. The film duration N is 100 minutes. The film pays 5 yuan in full.
(2) f (n) is a step function, f (n) =0 when n is equal to or less than 5, f (n) =5×10 when 5<n is equal to or less than 10, f (n) =5×30 when 10< n is equal to or less than 20, and f (n) =5 when n > 20. I.e., free for the first 5 minutes, 10% of the total charge is charged for 5 to 10 minutes, 30% of the total charge is charged for 10 to 20 minutes, and more than 20 minutes of the total charge is charged.
(3) g (N, N) is a discrete function, g (N, N) =n+5 when N < N; when N is n.gtoreq.n, g (N, N) =n+1.
(4) If the user views for 8 minutes, i.e., terminates the viewing, then after 5 minutes, i.e., 13 minutes, the user is automatically charged for 0.5 yuan, and the user is automatically refunded for 4.5 yuan.
(5) If the user views for 18 minutes, i.e., terminates the viewing, 1.5 yuan will be automatically collected for the user after 5 minutes, i.e., 23 minutes, and 3.5 yuan will be automatically returned for the user.
(6) If the user views for 28 minutes, i.e., terminates the viewing, the user 5-tuple is automatically collected after 5 minutes, i.e., 33 minutes.
(7) If the user has viewed the entire movie in its entirety, the user 5-gram will be automatically received at 101 minutes.
It can be seen that in the above process, the situation that the user is prompted to continue paying or is asked whether to continue watching, i.e. the video playing is interrupted or the user experience is affected by covering a semitransparent page on the video program, etc. will not occur halfway.
Based on the same technical concept, the embodiment of the present disclosure correspondingly further provides a video node, as shown in fig. 4, where the video node includes:
a setting module 41 configured to set a first payment transaction based on the smart contract;
