Security group action electronic payment method and system

The present invention relates to a group action electronic payment method and system, and more particularly to a security group action electronic payment method and system.

With the prosperity of the Internet and electronic devices, more and more users use the electronic devices to purchase audio and video services on the Internet, and the usage rate of such Internet-based audio and video services is also increasing. However, the traditional video and audio providing method provides video and audio information to a plurality of devices, and all of the devices purchase the same audio and video service, and the service providing server will wait for all the electronic devices in the devices to pay for the purchase. The video is transmitted to this group; as a result, there will be excess waiting for the payment time to affect the performance of the server.

In addition, the conventional service providing server needs to dynamically record the amount of data of the audio and video service purchased by each electronic device and charge accordingly. This will result in a large amount of data logging for the service provisioning server.

Furthermore, if a device in this group pays for a limited time due to the network or some unexpected factors, the service provider server will not only wait for the device to pay for the extra waiting time, but also because of this. The device moves out of the broadcast community and has redundant message transmission, for example, updating the key with the rest of the electronic devices of the group via unicast, which will greatly reduce the performance of the server.

Therefore, there is a need for how the audio-visual service provider can avoid the performance of waiting for the device to pay for, avoiding the need for the server to separately record the amount of information purchased by each device, and avoiding the frequent addition of a device in a short period of time. Moving out of the group and causing a large increase in the amount of information transmission affects the effectiveness, which is an important direction of current research and development.

The present application relates to a security group action electronic payment method and system, which can manage a broadcast group according to the number of tokens transmitted by an electronic device, thereby improving system tolerance; Transfer mode to send information to this broadcast group, which will greatly reduce user waiting time.

According to an aspect of the present invention, a security group action electronic payment system is proposed. The security group mobile electronic payment system includes a receiving module, a management module and a transmitting module. The receiving module is configured to receive a payment message, wherein the payment message includes a representative number. The management module adds the representative number to a broadcast group according to the payment message. The transmitting module transmits a message to the broadcast group in a multicast manner.

According to another aspect of the present invention, a security group action electronic payment method is provided, comprising the steps of: receiving a payment message, wherein the payment message includes a representative number; and adding the representative number to a broadcast group according to the payment message; And broadcasting a message to the broadcast group in a multicast manner.

In order to make the above-mentioned contents of the present invention more comprehensible, a preferred embodiment will be described below, and in conjunction with the drawings, a detailed description is as follows:

Although the invention will be fully described with reference to the preferred embodiments of the invention, it should be understood that those skilled in the art can modify the invention described herein while achieving the effect of the invention. . Therefore, it is to be understood that the following description is a broad disclosure of those skilled in the art and is not intended to limit the invention.

Please refer to the first figure, which is a system architecture diagram of an electronic payment system 100 according to an embodiment of the invention. In an embodiment, the electronic payment system 100 can include a security group mobile electronic payment system 110, an information providing system 120, and a purchasing group 130. The security group action electronic payment system 110 can include a receiving module 111, a management module 112, and a transmitting module 113. In an embodiment, the security group mobile electronic payment system may further include an encryption module 114. The purchase group 130 may include group devices 132-134, but an additional device 131 may be added. In this embodiment, the purchase group 130 includes the group devices 132-134 as an example. However, the present invention is not limited thereto, and the purchase group 130 may include not only three group devices, but also the purchase group 130. The existence of any group of devices, regardless of the number of devices, is within the scope of the invention.

The security group action electronic payment system 110, for example, a telecommunications carrier, provides audio and video information to the electronic device. The information providing system 120 is, for example, an information provider for providing information for the user to pay for the purchase of the audio and video information to the security group mobile electronic payment system 110, so that the information can be provided for the user to download. The management module 112 is used, for example, to manage a broadcast group, which includes respective representative numbers of devices to be transmitted. For example, the broadcast group has, for example, group devices 132-134 in the purchase group 130. Individual representative number.

In an embodiment, the device 131 for purchasing a specific information is linked to the security group mobile electronic payment system 110, and transmits a payment message to the receiving module 111, wherein the payment message may include, for example, One of the devices 131 represents a number.

In another embodiment, the device 131 for purchasing a specific information may be linked to the information providing system 120, and prepaid by credit card or other electronic transaction method to obtain a token, a point value, etc. corresponding to the payment amount. Indicates information that can be used to purchase audio and video information. The information providing system 120 can transmit the payment message to the receiving module 111. In one embodiment, the information providing system 120 can further transmit a consumer message to the receiving module 111. The consumer message includes, for example, a representative number representing the user device 131, a token, and a total amount of the token.

In this way, since the consumption mode adopts the pre-payment method, the information provider can avoid the situation that the consumer refuses to pay after downloading the information, and reduces the risk that the user does not pay; It is directly paid to the information provider, and there is no third party involved in it, which can reduce the occurrence of transaction fraud. In other words, this consumption pattern brings a win-win effect.

In an embodiment, the receiving module 111 receives the payment message, and the payment message may include a token, and the token corresponds to a quantity of information. For example, a generation of coins can correspond to an amount of information of 50 kb or 1 s in length. The management module 112 can add the representative number to a broadcast group according to the payment message, where the broadcast group includes the representative number of the information to be transmitted. In this embodiment, the representative number in the broadcast group is, for example, corresponding. To the group devices 132-134 in the purchase group 130. And before the representative number joins the broadcast group, the transmitting module 113 broadcasts the encrypted information to the purchase group 130, and the devices in the purchase group 130, for example, the group devices 132-134, have corresponding The key of the encryption method, so the information can be decrypted according to the key to retrieve the information. However, since the use device 131 having the representative number is added to the purchase group 130, the encryption method needs to be changed.

For example, when a representative number is added to the broadcast group, the encryption module 114 generates a first key to encrypt the information, and the transmitting module 113 transmits the first key to the unicast mode. The device 131 of the representative number transmits the first key in a multicast manner to the other group devices 132-134 of the purchase group 130 except the use device 131. In this way, the transmission module 113 can transmit the information to be transmitted to the purchase group 130 including the use device 131 and the group devices 132-134 in a multicast manner.

Moreover, after the representative number is added to the broadcast group and the key is updated, the transmitting module 113 can transmit information to the broadcast group in a multicast manner. When the transmitting module 113 transmits the information encrypted by the first key to a purchase group 130 including the using device 131 having the representative number, the transmitting module 113 transmits the requesting payment message and corresponding to the request. This information of the paid message is here to purchase the group 130. The transmitting module 113 is further configured to receive the payment message corresponding to the requested payment message.

For example, please refer to the fifth figure, which shows the corresponding timing diagram of the information transmitted by the transmission module 113, the request for payment message and the reception of the payment message. During the time period T1~T2, the purchase group 130 has transmitted the payment message to the receiving module 111, and the token in the payment message corresponds to the information transmitted by the transmission module 113 during the time period T1~T2. At time sequence T2, the transmitting module 113 transmits the payment information of the corresponding time period T2~T3 to the device in the group 130, and directly transmits the information of the time period T2~T3 and the required payment message of the corresponding time period T2~T3 to the purchasing group. The group 130, and the purchase group 130 is based on the information of the receiving time period T2~T3 and the required payment message of the corresponding time period T2~T3, and starts the payment mechanism, for example, transmitting the payment message corresponding to the time period T2~T3. Although the time period is taken as an example, the present invention is not limited thereto, and the magnitude of the transmission amount may be used as the separation.

In an embodiment, the token in the payment message corresponds to a quantity of the transmitted information, for example, a data amount of 50 kb or 1 s. After the transmitting module 113 transmits a request for a payment message and a certain amount of information for a certain period of time or a period of time, the receiving module 111 does not receive a token corresponding to the information transmitted by the representative number, and the management module 112 can Judging that this representative number owes a generation of coins. When the representative number owes the management module 112 a certain amount of tokens, for example, a token owed for three periods, and the receiving module 111 still does not receive the token owed by the representative number, the management module 112 can This representative number is removed from the purchase group 130. Although it is judged whether or not the representative number is removed from the purchase group 130 by the tokens owed for three periods, the present invention is not limited thereto, and any removal judgment criterion is within the scope of the present invention.

For example, a device in the group 130 is purchased, for example, using the device 131, and the payment message corresponding to the time period T2~T3 is not transmitted before the timing T3; and the security group action electronic payment system 110 is still at the timing T3, T4. The information of the transmission time periods T3~T4 and T4~T5, and the required payment messages of the corresponding time periods T3~T4 and T4~T5 are transmitted to the purchase group 130, including the use device 131. However, before the time series T5, the usage device 131 has not paid the payment messages for the corresponding time periods T2~T3, T3~T4 and T4~T5, so that the device 131 has accumulated three periods of tokens at the time sequence T5, then the management module 112 removes the representative number of the corresponding use device 131 from the broadcast group.

After the management module 112 removes the representative number from the broadcast group, the encryption module 114 generates and encrypts the information according to a new key, and the transmitting module 113 transmits the new key to the purchase by unicast. The group 130, at this time, the broadcast group does not include the representative number, and the purchase group 130 does not include the use device 131.

For example, at time T5, the transmitting module 113 transmits the new key to the group devices 132-134 in a unicast manner, and then the information transmitted by the transmitting module 113 is encrypted with a new key. . Since the user device 131 having the removed representative number does not have the new key, the information transmitted by the transmission module 113 during the period T5~T6 and thereafter cannot be retrieved.

In this way, since the management module 112 does not immediately remove the representative number from the broadcast group if any representative number owes a token, this will prevent the unnecessary key update procedure from occurring. For example, when a device of a representative device causes a payment message to be transmitted to the receiving module 111 before the deadline due to certain factors, such as network delay or device execution, if the management module 112 immediately If the representative number is removed by the broadcast group, the security group action electronic payment system 110 needs to perform the key update immediately, and the transfer module 113 will unicast the new key to the broadcast group. When the receiving module 111 receives the payment message of the device, the transmitting module 113 needs to separately transmit the new key to the broadcast group and the device in a unicast and multicast manner. As such, if the device repeatedly experiences a payment delay, the key update procedure will occur repeatedly to make the security group action electronic payment system 110 less effective.

By delaying the payment delay of the device by tolerating a device owing the tokens for three periods, the system performance can be avoided by the repeated update of the key. In addition, in this embodiment, the threshold value is used for the three periods of time, which is a limit value for better performance after research. If the accumulation is too small, it is difficult to manage, and if the accumulation is too small, the key update program will still be Repeatedly. However, the invention is not limited thereto, and the threshold value is more or less than three tokens, and is within the scope of the invention.

If the device that owes the token is to be re-joined to the purchase group 130, in an embodiment, the owed token must be paid in one time in the payment message before re-joining the purchase group 130. This makes it easier to manage broadcast groups.

Please refer to the second figure, which illustrates a flow chart of a security group action electronic payment method 200 according to an embodiment of the invention. Please refer to the first and fifth figures at the same time.

In step S210, a payment message is received, wherein the payment message includes a representative number.

In step S220, the representative number is added to a broadcast group according to the payment message.

In step S230, the information is transmitted to the broadcast group in a multicast manner.

Please refer to the third figure, which illustrates a flowchart of a security group action electronic payment method 300 according to another embodiment of the present invention. Please refer to the first and fifth figures at the same time.

In step S310, a payment message is received, wherein the payment message includes a representative number.

In step S320, the representative number is added to a broadcast group according to the payment message, and a first key is generated to encrypt the information.

In step S330, the first key is transmitted to the device having the representative number in a unicast manner, and the first key is transmitted to the broadcast group in a multicast manner.

Please refer to the fourth figure, which illustrates a flow chart of a method 400 for removing a representative number according to the present invention. Please refer to the first and fifth figures at the same time. In step S410, when a certain amount of information is transmitted to the representative number, and the token of the corresponding amount of the corresponding information transmitted by the representative number is not received, it is determined that the representative number accumulates the token.

In step S420, when the representative number owes a certain amount of tokens, in one embodiment, for example, the tokens corresponding to the three time periods are accumulated, and the representative number is removed from the broadcast group.

In step S430, the information is encrypted with a second key, and the second key is transmitted to the broadcast group by unicast.

The security group action electronic payment method and system disclosed in the above embodiments of the present invention manages the broadcast group by the number of tokens owed by the device, and does not need to separately count the amount of information transmitted to the respective devices, and then according to the information. The amount of information transmitted is charged to the individual device. In this way, because the prepaid method is used for management, the information provider can reduce the risk of the user not paying; and for the user, the transaction fraud can be reduced, and the consumption mode is adopted. Bring a win-win effect.

Moreover, since the information is transmitted first and then charged, it is possible to avoid waiting for the device to pay and delay the information transmission time. In addition, because the device can be tolerated, and the system does not deliberately owe the system, the system still updates the key, resulting in a process of unnecessary update of the key and the system performance is low.

Moreover, since the present invention employs a micropayment mechanism, that is, the usage device pays based on the token, the user can clearly know the remaining available credit. Even if the security group action electronic payment system updates the charging standard, for example, if the information of one time period is changed to charge 1.5 tokens, the user can immediately know and judge the amount of information that the remaining tokens can purchase, which makes Transaction is transparent.

The above technical features completely solve the shortcomings of the traditional online paid purchase of audio and video services, and can be widely applied to various network multicast broadcast services, digital TV, instant payment systems and the like. Therefore, the security group action electronic payment method and system proposed in this application not only improves the shortcomings of the conventional knowledge but also improves the performance.

In view of the above, the present invention has been disclosed in a preferred embodiment, and is not intended to limit the present invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
