[0041] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0042] The method for determining the currency transaction path provided in the embodiment of the present application can be applied to various scenarios in which the currency transaction path from the target address to the key address is determined. It should be noted that the currency described in the embodiment of the present application is a legal currency, such as RMB, US dollars, etc.

[0043] The execution entity of the method for determining a currency transaction path provided in the embodiment of the present application may include but is not limited to electronic devices such as mobile phones, tablet computers, laptop computers, and desktop computers.

[0044] See also Figure 1 , Figure 1 This is a flowchart of a method for determining a currency transaction path provided in an embodiment of the present application. The method for determining a currency transaction path provided in an embodiment of the present application may include steps S101 to S104, which are described in detail as follows:

[0045] In S101 , at least one key address is obtained, and a set of N associated addresses associated with the at least one key address is obtained.

[0046] The N associated address sets include a first-level associated address set to an N-th-level associated address set, the first-level associated address set includes at least one first-level associated address, the N-th-level associated address set includes at least one N-th-level associated address, there is a preset currency transaction behavior between the first-level associated address and at least one key address, there is a preset currency transaction behavior between the N-th-level associated address and the N-1-th-level associated address, and N≥1.

[0047] In an embodiment of the present application, the electronic device may obtain at least one key address from a preset target address library, and obtain a set of N associated addresses associated with the at least one key address.

[0048] Exemplarily, the user may input the target address library into the electronic device so that the electronic device may obtain the target address library. After obtaining the target address library, the electronic device may first determine at least one key address in the target address library.

[0049] In one possible implementation, the electronic device may search for at least one address with a preset tag from a preset target address library as at least one key address. Exemplarily, the preset tag may include, but is not limited to, an exchange, a cross-chain bridge, and the like.

[0050] After determining at least one key address, the electronic device may obtain, based on the at least one key address, N sets of associated addresses associated with the at least one key address. A preset monetary transaction behavior exists between a first-level associated address included in a first-level associated address set in the N sets of associated addresses and the at least one key address, a preset monetary transaction behavior exists between a second-level associated address included in a second-level associated address set in the N sets of associated addresses and the at least one first-level associated address, and so on, a preset monetary transaction behavior exists between an N-th-level associated address included in an N-th-level associated address set in the N sets of associated addresses and the at least one N-1-th-level associated address.

[0051] In the embodiment of the present application, the preset currency transaction behavior may include a transaction behavior in which the currency flows in a preset direction. For example, the preset currency transaction behavior between address A and address B may be a currency transaction behavior in which the currency of address B flows to address A. Of course, the preset currency transaction behavior between address A and address B may also be a currency transaction behavior in which the currency of address A flows to address B. For the sake of convenience of description, the preset currency transaction behavior between address A and address B in the embodiment of the present application is a currency transaction behavior in which the currency of address B flows to address A.

[0052] The following provides an example of obtaining a key address and a set of N associated addresses. Figure 2 , Figure 2A schematic diagram of a key address and a set of N associated addresses provided in an embodiment of the present application.

[0053] exist Figure 2 In the example, the preset target address library may include address 1, address 2, address 3, address 4, address 5, address 6, address 7, address 8, and address 9. The key addresses may be address 1 and address 9. The arrow between any two addresses may indicate that there is a currency transaction between the two addresses, and the direction of the arrow may indicate the flow direction of the currency. Since there is a preset currency transaction between address 1 and address 2 (i.e., there is a currency transaction between address 1 and address 2, where the currency of address 2 flows to address 1), address 2 may be a first-level associated address. Similarly, address 3 and address 4 may also be first-level associated addresses. In addition, since there is also a preset currency transaction between address 8 and address 9, address 8 may be a first-level associated address. That is, the first-level associated address set may include address 2, address 3, address 4, and address 8.

[0054] Similarly, for the first-level associated addresses of address 2, address 3, address 4 and address 8 in the first-level associated address set, address 3, address 6 and address 7 can be determined as second-level associated addresses, so the second-level associated address set can include address 3, address 6 and address 7.

[0055] Similarly, for the second-level associated addresses of address 3, address 6, and address 7 in the second-level associated address set, address 5 and address 8 can be determined to be third-level associated addresses, so the third-level associated address set can include address 5 and address 8.

[0056] After obtaining N associated address sets, the electronic device can determine whether there are at least two associated address sets in the N associated address sets that have the same address. If it is determined that there are at least two associated address sets in the N associated address sets that have the same address, the same address in all associated address sets whose corresponding addresses have a non-highest criticality level among the at least two associated address sets that have the same address is deleted.

[0057] It should be noted that in the embodiment of the present application, the criticality level of each critical address is greater than the criticality level of each first-level associated address, the criticality level of each first-level associated address is greater than the criticality level of each second-level associated address, and so on. The criticality level of each N-1th level associated address is greater than the criticality level of each Nth level associated address.

[0058] by Figure 2Taking the example shown as an example, since the first-level associated address set includes address 2, address 3, address 4 and address 8, the second-level associated address set includes address 3, address 6 and address 7, and the third-level associated address set may include address 5 and address 8.

[0059] It can be seen that both the first-level association address set and the second-level association address set include address 3. Since the criticality level of the addresses corresponding to the first-level association address set is higher than that of the addresses corresponding to the second-level association address set, the second-level association address set is "the set of all association addresses whose corresponding addresses do not have the highest criticality level." In other words, the same addresses in the second-level association address set can be deleted, that is, address 3 in the second-level association address set can be deleted. In this case, address 3 is a first-level association address, not a second-level association address.

[0060] Similarly, the first-level associated address set and the third-level associated address set both include address 8. Since the criticality level of the addresses corresponding to the first-level associated address set is higher than that of the addresses corresponding to the third-level associated address set, the third-level associated address set is "the set of all associated addresses whose corresponding addresses do not have the highest criticality level." That is, the same addresses in the third-level associated address set can be deleted, that is, address 8 in the third-level associated address set can be deleted. At this time, address 8 is a first-level associated address, not a third-level associated address.

[0061] After completing the above steps, the key addresses are address 1 and address 9, the first-level associated address set includes address 2, address 3, address 4 and address 8, the second-level associated address set includes address 6 and address 7, and the third-level associated address set may include address 5.

[0062] Through the steps of this embodiment, the electronic device can obtain the key address and the multi-level associated address set associated with the key address, thereby determining the criticality of each address in each associated address set.

[0063] In S102, the criticality level of at least one critical address and the criticality level of each address in the set of N associated addresses are determined respectively.

[0064] In an embodiment of the present application, after obtaining the key address and the N associated address sets, the electronic device may determine the criticality level of each key address, and determine the criticality level of each address in the N associated address sets.

[0065] Among them, the rules for determining the criticality level are consistent with the rules for determining the criticality level described in S101, that is, the criticality of each critical address is equal to or greater than the criticality level of each first-level associated address, and the criticality level of each N-1th level associated address is greater than the criticality level of each Nth level associated address.

[0066] exist Figure 2 In the corresponding example, the critical addresses are address 1 and address 9, the first-level associated address set includes address 2, address 3, address 4 and address 8, the second-level associated address set includes address 6 and address 7, and the third-level associated address set may include address 5. Based on the above rules for determining the criticality level, it can be concluded that the criticality level of address 1 and address 9 is the highest level, the criticality level of address 2, address 3, address 4 and address 8 is the second highest level, the criticality level of address 6 and address 7 is the third highest level, and the criticality level of address 5 is the fourth highest level.

[0067] Through the steps of this embodiment, the electronic device can determine the criticality level of the critical address and the criticality level of each address in the set of N associated addresses, so that the currency transaction path can be determined according to the criticality of each address, thereby reducing the analysis and retrieval of non-critical addresses, and ultimately improving the efficiency of determining the currency transaction path.

[0068] In S103 , a target address of the currency transaction path to be obtained is determined from the N associated address sets.

[0069] In an embodiment of the present application, after obtaining N associated address sets, the electronic device may determine the target address of the currency transaction path to be obtained from the N associated address sets.

[0070] For example, the user may input the target address of the currency transaction path to be obtained into the electronic device so that the electronic device can obtain the target address.

[0071] The target address can be any one of the N associated addresses, and the target address can be set according to the user's needs. For example, when the user wants to determine the currency transaction path between address 5 and the key address, the electronic device can determine address 5 as the target address of the currency transaction path to be obtained.

[0072] In S104, a currency transaction path from the target address to the critical address is determined based on the criticality level of the target address, the criticality level of at least one critical address, and the criticality level of each address in the set of N associated addresses.

[0073] In an embodiment of the present application, after determining the target address, and determining the criticality level of each critical address and the criticality level of each address in the set of N associated addresses, the electronic device can first determine the criticality level of the target address, and then determine the currency transaction path from the target address to the critical address based on the criticality level of the target address, the criticality level of at least one critical address, and the criticality level of each address in the set of N associated addresses.

[0074] In one possible implementation, the electronic device may determine the currency transaction path from the target address to at least one key address through steps a to c, as detailed below:

[0075] In step a, a current address that has a preset currency transaction behavior with a target address is determined from at least one key address and a set of N associated addresses.

[0076] The criticality level of the current address is greater than the criticality level of the target address.

[0077] In this implementation, when it is necessary to determine the currency transaction path from the target address to the key address, the electronic device can first determine from at least one key address and a set of N associated addresses that there is a preset currency transaction behavior with the target address, and the criticality level is greater than the current address of the target address.

[0078] by Figure 2 Taking the example in as an example, the target address can be address 5. Since there is a currency transaction behavior from address 5 to address 6, that is, there is a preset currency transaction behavior between address 6 and address 5, and since the criticality level of address 6 is greater than the criticality level of address 5, the electronic device can determine that the current address is address 6.

[0079] In step b, if the current address is any key address, the currency transaction path is determined based on the target address and the current address.

[0080] In this implementation, each time a new current address is determined, the electronic device can determine whether the current address is any key address. If the current address is any key address, the currency transaction path is determined based on the target address and the current address.

[0081] by Figure 2 Taking the example in as an example, since the current address is address 6 at this time, and address 6 is not any key address, the electronic device may not execute the step of determining the currency transaction path according to the target address and the current address, but may execute step c.

[0082] In step c, if the current address is not any one of the key addresses, the target address is replaced by the current address, and the step of determining the current address having the preset currency transaction behavior with the target address from the at least one key address and the N associated address set is executed again.

[0083] In the present embodiment, after a new current address is determined each time, the electronic device can determine whether the current address is any one of the key addresses, and if the current address is not any one of the key addresses, the target address can be replaced by the current address, and the step of determining the current address having the preset currency transaction behavior with the target address from the at least one key address and the N associated address set is executed again.

[0084] For example, in the example in Table 1, since the latest current address is address 6, and address 6 is not any one of the key addresses, the electronic device can replace the original target address (address 5) with the current address (address 6), and determine the current address having the preset currency transaction behavior with the new target address (address 6) from the at least one key address and the N associated address set again. Figure 2

[0085] Since there is a preset currency transaction behavior between address 2 and address 6, and since the key degree level of address 2 is greater than the key degree level of address 6, the electronic device can determine that the current address is address 2.

[0086] After the latest current address (address 2) is determined, the electronic device can determine whether the new current address (address 2) is any one of the key addresses, and since the new current address (address 2) is not any one of the key addresses, the electronic device can replace the original target address (address 6) with the current address (address 2), and determine the current address having the preset currency transaction behavior with the new target address (address 2) from the at least one key address and the N associated address set again.

[0087] Since there is a preset currency transaction behavior between address 1 and address 2, and since the key degree level of address 1 is greater than the key degree level of address 2, the electronic device can determine that the current address is address 1.

[0088] ​After determining the latest current address (address 1), the electronic device can determine whether the new current address (address 1) is any key address. Since the new current address (address 1) is any key address, the electronic device can determine the currency transaction path based on each target address (address 5, address 6, address 2) and the current address (address 1). Specifically, the electronic device can determine the set of paths from address 5 to address 6, the path from address 6 to address 2, and the path from address 2 to address 1 as the currency transaction path from the target address to the key address.

[0089] The following is an analysis of the technical effects of the method for determining the currency transaction path provided in this application with reference to examples:

[0090] Likewise Figure 2 Taking the example shown as an example, and taking address 3 as the target address, it is necessary to determine the currency transaction path between address 3 and any key address.

[0091] When the target address is address 3, according to the method for determining the currency transaction path provided in the embodiment of the present application, the determined currency transaction path is the path from address 3 to address 1, rather than the path from address 3 to address 2 and from address 2 to address 1. Therefore, in the process of determining the currency transaction path by the method for determining the currency transaction path provided in the embodiment of the present application, there is no need to analyze and retrieve the uncritical address (address 2).

[0092] However, since the method for determining the currency transaction path in the prior art does not determine the currency transaction path based on the criticality level, the currency transaction path determined by the method for determining the currency transaction path in the prior art includes the path from address 3 to address 1, and the path from address 3 to address 2 and the path from address 2 to address 1. Therefore, in the process of determining the currency transaction path using the method for determining the currency transaction path in the prior art, it is necessary to analyze and retrieve the non-critical address (address 2).

[0093] In actual applications, since criminals may interfere by transferring a large number of small amounts or distributing transfers back and forth among multiple addresses, there may be many non-critical addresses similar to address 2. Since the method for determining the currency transaction path provided in the embodiment of the present application does not require analysis and retrieval of all non-critical addresses in the process of determining the currency transaction path, the efficiency of determining the currency transaction path can be greatly improved.

[0094] As can be seen from the above, in the method for determining a currency transaction path provided in the embodiment of the present application, at least one key address is first obtained, as well as a set of N associated addresses associated with the at least one key address, and then the criticality level of the at least one key address and the criticality level of each address in the set of N associated addresses are determined respectively. Then, the target address of the currency transaction path to be obtained is determined from the set of N associated addresses, and finally, the currency transaction path from the target address to the key address is determined based on the criticality level of the target address, the criticality level of the at least one key address, and the criticality level of each address in the set of N associated addresses. In the method of the present application, the criticality level of the key address and the criticality level of each associated address can be determined first, and then the currency transaction path can be determined based on the criticality level of each address. Therefore, the analysis and retrieval of non-critical addresses can be reduced based on the criticality level, thereby improving the efficiency of determining the currency transaction path.

[0095] In one possible implementation, after determining the currency transaction path, the electronic device may also determine the address in the currency transaction path that has a preset currency transaction behavior with at least one key address as a key interaction address, and after determining the key interaction address, the electronic device may perform risk identification on the key interaction address.

[0096] by Figure 2 Taking the example in as an example, when the target address is address 5, the currency transaction path is the set of the path from address 5 to address 6, the path from address 6 to address 2, and the path from address 2 to address 1. Therefore, in this currency transaction path, the address that has a preset currency transaction behavior with the key address is address 2. Therefore, address 2 can be determined as the key interaction address and risk identification is performed on address 2.

[0097] Continue with Figure 2 Taking the example in as an example, when the target address is address 3, the currency transaction path is the path from address 3 to address 1. Therefore, in this currency transaction path, the address that has a preset currency transaction behavior with the key address is address 3. Therefore, address 3 can be determined as the key interaction address and risk identification of address 3 can be performed.

[0098] It should be noted that the key interaction address and the non-key address will also be different depending on the target address. For example, when the target address is address 5, the key interaction address is address 2; when the target address is address 3, the key interaction address is address 3, and the non-key address is address 2.

[0099] In an embodiment of the present application, after risk identification is performed on a key interaction address, if it is identified that the key interaction address has a risk, the electronic device may also take preset measures to perform risk control on the key interaction address.

[0100] In one possible implementation, after determining the currency transaction path, the electronic device can determine whether the number of currency transaction paths is greater than or equal to two. If the electronic device determines that the number of currency transaction paths is greater than or equal to two, the electronic device can determine the number of addresses contained in each currency transaction path and the total amount involved in the preset currency transaction behaviors between each address contained in each path, and can determine the key transaction path from each currency transaction path based on the number of addresses contained in each currency transaction path and the total amount involved in the preset currency transaction behaviors between each address contained in each path.

[0101] For example, if there are two currency transaction paths, and the two currency transaction paths each contain the same number of addresses, and the total amount involved in the preset currency transaction behaviors between the addresses included in currency transaction path 1 is greater than the total amount involved in the preset currency transaction behaviors between the addresses included in currency transaction path 2, then currency transaction path 1 can be determined as the key transaction path.

[0102] If the total amount involved in the preset currency transactions between the addresses contained in the two currency transaction paths is the same, and the number of addresses contained in currency transaction path 1 is less than the number of addresses contained in currency transaction path 2, then currency transaction path 1 can be determined to be the key transaction path.

[0103] If two currency transaction paths each contain different total amounts involved in the pre-set currency transactions between addresses and also contain different numbers of addresses, the key transaction path can be determined based on a pre-set first weight corresponding to the total amount and a pre-set second weight corresponding to the number of addresses. The first and second weights can be set based on actual user needs and are not limited here.

[0104] After determining the key transaction path, users can focus on analyzing and controlling the key transaction path.
