Detailed Description
Exemplary embodiments of the invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.
Fig. 1 is a schematic diagram of the main steps of a method of managing the number of transactions of digital money according to an embodiment of the present invention.
As shown in fig. 1, when the method for managing transaction times of digital money according to the embodiment of the present invention is applied to the first digital money terminal, the method mainly includes the following steps:
step S101: receiving a transaction request indicating a digital currency to be transacted and a number of transacted times for the digital currency, an attribute of the digital currency including a transaction number threshold.
The transaction request can be sent by the second digital currency terminal (the payer of the digital currency), and the transaction request can be directly sent to the first digital currency terminal by the second digital currency terminal, and can also be determined by the first digital currency terminal when the second digital currency terminal carries out transaction.
The transaction number threshold of the digital currency may be included in the digital currency, and the specific value thereof may be written in the fields of the digital currency in a clear text form or may be written in the fields of the digital currency in a non-clear text form (e.g., a default value). The transaction number threshold is set by the money management apparatus that derives the digital money at the time of initial derivation of the digital money. The money management device may determine the transaction count threshold value of the digital money based on terminal information of a terminal that transmits the digital money generation request and/or user information corresponding to the digital money generation request. For example, the terminal information may be terminal hardware information, such as a chip model number. For example, the newer the chip model and the larger the terminal memory capacity are, the larger the transaction number threshold corresponding thereto is. For another example, the more the available balance of the account corresponding to the user information is, the larger the threshold of the transaction times corresponding to the user information is.
Step S102: and determining whether the number of traded times is less than the threshold number of traded times, and if so, trading according to the digital currency.
The number of times of transaction may be recorded in the digital money, and the initial value of the number of times of transaction is 0, that is, when the digital money has just been exported from the money management apparatus without being transacted, the value of the field corresponding to the number of times of transaction in the digital money is 0. When the first digital currency terminal conducts transaction according to the digital currency, the field corresponding to the number of times of transaction can be assigned in an increasing mode. The transacted digital currency can be written into the digital currency by the currency management device when being exported, or fields corresponding to the transacted times can be added in the transacted digital currency by the first digital currency terminal during transaction by adopting a corresponding logic algorithm, and the fields corresponding to the transacted times are assigned in an increasing mode.
Before the transaction is carried out, the first digital currency terminal needs to verify whether the number of times of the transaction of the digital currency is smaller than a transaction number threshold value, if the number of times of the transaction is smaller than the transaction number threshold value, the transaction is carried out according to the digital currency, and when the number of times of the transaction of the digital currency is not smaller than the transaction number threshold value, the first digital currency terminal rejects the transaction corresponding to the transaction request and can return the result of rejecting the transaction to the second digital currency terminal which extracts the transaction request. Therefore, the safety of the first digital currency terminal and the second digital currency terminal in the off-line transaction process is ensured by limiting the transaction times of the digital currency.
According to the above embodiments, when the method for managing the number of times of digital money transactions provided by the embodiments of the present invention is applied to the first digital money terminal, the method mainly includes the following steps:
step S201: receiving a transaction request indicating a digital currency to be transacted and a number of transacted times for the digital currency, an attribute of the digital currency including a transaction number threshold.
Step S202: and judging whether the number of times of transaction is smaller than a transaction number threshold value, if so, executing step S203, otherwise, executing step S204.
Step S203: and carrying out transaction according to the digital currency, increasing the number of times of transaction of the digital currency and ending the current process.
Step S204: and rejecting the transaction corresponding to the transaction request.
A method of managing transaction times of digital money according to an embodiment of the present invention may be seen in that when a transaction request is received by a first digital money terminal, it may be determined whether a number of times that digital money has been transacted is less than a transaction time threshold value according to a number of times that digital money indicated in the transaction request has been transacted and a transaction time threshold value included in an attribute of the digital money, the transaction time threshold value being determined by a money management apparatus that derives the digital money when the digital money is derived. When the number of times of trading of the digital currency is smaller than the threshold value of the number of times of trading, the first digital currency terminal conducts trading according to the digital currency. Therefore, the safety of off-line transaction is guaranteed by controlling the transaction times of the digital currency in the transaction process.
Fig. 3 is a diagram illustrating the main steps of a method for managing the number of transactions of digital money according to an embodiment of the present invention.
As shown in fig. 3, the method for managing the transaction count of digital money according to the embodiment of the present invention, when applied to a money management apparatus, mainly comprises the following steps:
step S301: and receiving a digital currency generation request sent by a second digital currency terminal, wherein the currency generation request indicates the denomination of the requested digital currency and user information corresponding to the second digital currency terminal.
Since one piece of digital money can be transacted several times, the second digital money terminal may be a terminal transacting with the first digital money terminal, or may be only a terminal for exporting digital money. For example, after the digital currency is exported from the second digital currency terminal, a transaction may be first conducted with the third digital currency terminal based on the digital currency, and then the third digital currency terminal may continue to conduct transactions with the first digital currency terminal based on the digital currency. In the embodiment of the present invention, for convenience of description, a transaction between the second digital money terminal and the first digital money terminal is taken as an example.
The user of the second digital money terminal may send a digital money generation request indicating the denomination of the requested digital money and user information corresponding to the digital money terminal to the money management apparatus through the second digital money terminal according to the derivation demand of the digital money. For example, when the user has to derive digital money of 10 denominations, the denomination indicated by the digital money generation request is 10, and the user information may be registration information of the second digital money terminal, and it is understood that the user information has been recorded in the money management apparatus in advance, so that the money management apparatus can generate digital money corresponding to the user information in accordance with the digital money generation request.
Step S302: and determining a transaction number threshold of the digital currency according to the user information.
The money management device may determine the transaction count threshold value of the digital money based on terminal information of a terminal that transmits the digital money generation request and/or user information corresponding to the digital money generation request. For example, the terminal information may be terminal hardware information, such as a chip model number. For example, the newer the chip model and the larger the terminal memory capacity are, the larger the transaction number threshold corresponding thereto is. For another example, the more the available balance of the account corresponding to the user information is, the larger the threshold of the transaction times corresponding to the user information is.
Step S303: and generating digital currency corresponding to the user information and the denomination according to the transaction number threshold value, and informing the second digital currency terminal of the digital currency.
After generating the requested digital money, the money management apparatus may directly notify the digital money terminal of the generated digital money, and the contents of the digital money may include: the digital currency unique identifier (e.g., a crown number), the identification of the currency management device, and the signature of the currency management device, as well as a transaction count threshold for the digital currency. In addition, when the digital money is generated, the money management apparatus may also record the number of times the digital money has been traded in the digital money, the initial value of the number of times traded being 0, that is, the value of the field in the digital money corresponding to the number of times traded being 0 when the digital money has just been exported from the money management apparatus without being traded. When the number of times the digital currency has been traded is also recorded in the digital currency, the contents of the digital currency include: the digital currency unique identification (e.g., a crown number), the identification of the currency management device and the signature of the currency management device, the transaction count threshold for the digital currency, and the number of times the digital currency has been transacted.
According to the above embodiment, when the first digital money terminal performs an offline transaction with the second digital money terminal, as shown in fig. 4, a method for managing the number of digital money transactions according to an embodiment of the present invention may include the following steps:
step S401: the money management device receives a digital money generation request transmitted from a second digital money terminal, the money generation request indicating a denomination of the requested digital money, user information corresponding to the second digital money terminal, and terminal information of the second digital money terminal.
Step S402: the money management device determines a transaction number threshold of digital money based on the user information and the terminal information.
Step S403: the money management device generates digital money corresponding to the user information and the denomination according to the transaction number threshold.
Step S404: the money management means notifies the second digital money terminal of the digital money.
Step S405: the second digital currency terminal sends a transaction request to the first digital currency terminal, the transaction request indicating the digital currency to be transacted and the number of times the digital currency has been transacted.
Step S406: the first digital money terminal determines whether the number of traded times is less than the threshold number of traded times, and performs step S407 and step S408 when the number of traded times is less than the threshold number of traded times, otherwise performs step S409.
Step S407: and the first digital currency terminal carries out off-line transaction with the second digital currency terminal according to the digital currency.
Step S408: the first digital money terminal increments the number of times the digital money has been traded.
Step S409: the first digital currency terminal refuses to conduct a transaction corresponding to the transaction request with the second digital currency terminal.

The modules described in the embodiments of the present invention may be implemented by software or hardware. The described modules may also be provided in a processor, which may be described as: a processor includes a first receiving module and a transaction module. Where the names of these modules do not in some cases constitute a limitation on the module itself, for example, the first receiving module may also be described as the "module receiving the transaction request".
As another aspect, the present invention also provides a computer-readable medium that may be contained in the apparatus described in the above embodiments; or may be separate and not incorporated into the device. The computer readable medium carries one or more programs which, when executed by a device, cause the device to comprise: receiving a transaction request indicating digital currency to be transacted and a number of transacted times for the digital currency, an attribute of the digital currency comprising a transaction number threshold; determining whether the number of traded times is less than the threshold number of traded times, and if so, conducting a transaction according to the digital currency.
According to the technical scheme of the embodiment of the invention, when the first digital currency terminal receives the transaction request, whether the number of times of the digital currency that has been transacted is smaller than the transaction number threshold can be determined according to the number of times of the digital currency that is indicated in the transaction request and the transaction number threshold that is included in the attribute of the digital currency, and the transaction number threshold is determined by the currency management device that derives the digital currency when the digital currency is derived. When the number of times of trading of the digital currency is smaller than the threshold value of the number of times of trading, the first digital currency terminal conducts trading according to the digital currency. Therefore, the safety of off-line transaction is guaranteed by controlling the transaction times of the digital currency in the transaction process.
The above-described embodiments should not be construed as limiting the scope of the invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
