Under above-mentioned running environment, according to the first aspect of the present embodiment, a kind of risk control of logical card operation is provided
Method processed, this method are realized by air control platform 300 shown in Fig. 2.Fig. 3 shows the flow diagram of this method, with reference to Fig. 3
It is shown, this method comprises:
S302: the instruction for carrying out logical card operation with second user on block chain is received from the terminal device of the first user；
And
S304: handling instruction, to control the risk of logical card operation.
Specifically, the first user 100 carries out logical card by terminal device 110 on block catenary system 200 with second user
Operation.The logical card operation for example can be the operation that the first user 110 transfers accounts to second user, and certainly, which may be used also
To be other kinds of logical card operation.But for ease of description, in the present embodiment, it will be used with the first user 110 to second
The logical card operation is described for the operation scenario that family is transferred accounts.It should be clear to a person skilled in the art that the technology of the disclosure
Scheme can be applicable to other kinds of logical card operation.
Then, air control platform 300 receives the first user 110 in block catenary system from the terminal device 110 of the first user 100
The instruction (i.e. step S302) of the 200 logical card operations transferred accounts to second user.Then air control platform 300 carries out the instruction
The risk that processing this time transfers accounts to control and (leads to card operation).
As described in the background art, lack effective air control measure currently based on the digital cash operation of block chain,
Therefore risk control can not be carried out to the operation of digital cash.For example, the existing digital cash scheme based on block chain lacks
Risk control to transaction limit and transaction count.When user is in transfer operation since maloperation (such as accidentally will be small
Several point points are wrong), when leading to the transfer operation for great number occur, huge loss can be brought to user.Alternatively, if the account of user
It is stolen, to, due to lacking the precautionary measures, will lead to user's when the criminal for stealing account disposably empties the user account
Account is emptied to bring massive losses to user.Alternatively, the account of user is in a short time (such as in 24 hours) frequent
, there is multiple transfer operation in transaction, if be not controlled, can also there is the risk that loss is brought to user.
For technical problem described in background technology, the present embodiment is provided between user and block catenary system and is used for
Control the air control platform of the risk of the logical card operation of user.Relative to user 100 using the terminal device 110 of oneself directly in area
It being operated on block catenary system 200, the disclosure is provided with air control platform 300 between user 100 and block catenary system 200, from
And air control platform 300 can serve as the agency that user 100 is operated on block catenary system 200.Furthermore according to presetting
Program, the instruction operated for logical card that air control platform 300 can issue user 100 is handled, to control user 100
Logical card operation risk.
To which the present embodiment can efficiently control the wind that user carries out logical card operation on block chain in this way
Danger.The operation for solving the digital cash existing in the prior art based on block chain lacks the technology of corresponding risk control and asks
Topic.
Optionally, instruction is handled, to control the operation of the risk of logical card operation, comprising: according to pre-set
Rule determines the operation of logical card, and is determined whether to send instructions to block chain according to the result of judgement.
Specifically, with reference to shown in Fig. 4.In order to realize the risk control of air control platform 300, user 100 can pass through terminal
The rule for air control is arranged in equipment 110 on air control platform 300.Then, air control platform 300 will record the rule of user setting
Then.
In this way, when user 100 sends the instruction for carrying out logical card operation by terminal device 110 to block catenary system 200
(for example, transfer instructions after the signature of user 100), air control platform 300 can use public key and test the instruction of user 100
Card.
Then air control platform 300 can determine whether the transfer instructions meet in advance according to the pre-set rule of user 100
The rule of setting.If air control platform 300 determines the instruction character normally, the instruction that user 100 issues is sent to block
Catenary system 200 is to execute corresponding operation in block catenary system.Otherwise, which is sent to area by the refusal of air control platform 300
Block catenary system 200, and user can also be notified to refuse the operation.
Certainly, which must be not necessarily that user is pre-set, for example, it is also possible to by third-party safe machine
The pre-set rule of structure.
To which in this way, the mode of setting rule can be taken, the risk control that the logical card of user 100 is operated
System is in the range of rule allows.It is thus possible to control the risk range of logical card operation by way of setting rule.To
It realizes and sharing control is adjusted flexibly.Be conducive to for different users and the different logical card operation scenarios done, setting
Different rule, to realize flexible control.
Specifically, the operation of logical card is determined according to preset rules, and is according to the determination of the result of judgement
The no operation for sending instructions to block chain, comprising: determine whether the amount of logical card operation reaches first threshold；And in amount
Refusal sends instructions to block chain in the case where reaching first threshold, or will in the case where amount is not up to first threshold
Instruction is sent to block chain.
For example, as described in the background art, user may be due to maloperation (such as accidentally in transfer operation
Decimal point point is wrong), lead to the transfer operation for great number occur.In addition, if the account of user is stolen, to steal the criminal of account
Guilty person can empty the user account only by once transferring accounts.Therefore, it can cause greatly to lose to user.
For the problem existing in the prior art, the highest amount that single is transferred accounts can be set in air control platform 300
(the i.e. described first threshold).To which when the amount that single is transferred accounts is not up to the highest amount, air control platform 300 just transfers accounts this
The instruction of operation is sent to block catenary system 200, thus the complete transfer operation.Otherwise, when the amount that single is transferred accounts reaches this
When highest amount, just the instruction of the transfer operation is sent to block catenary system 200 to air control platform 300 by refusal, and to user
100 terminal device 110 sends notice.
The risk of logical card operation is carried out to which user in this way, can be efficiently controlled in block catenary system.
Optionally, in addition, the operation of logical card is determined according to preset rules, and the result determination determined is
The no operation for sending instructions to block chain, comprising: determine account for executing logical card operation within a preset time period
Whether logical card number of operations reaches second threshold；And refusal will instruction in the case where logical card number of operations reaches second threshold
It is sent to block chain, or sends instructions to block chain in the case where logical card number of operations is not up to second threshold.
Specifically, air control platform 300 can parse this and refer to after the instruction for receiving the transfer operation that terminal 110 is sent
It enables, the first user 100 of analysis is to be transferred accounts by which account to second user.After obtaining the account for transferring accounts, wind
Total gold that control platform 300 can transfer accounts the account in scheduled time (such as in 24 hours, in one week or in 30 days, etc.)
Whether volume, which has reached, presets Maximum Amount (i.e. second threshold).It, will if air control platform 300 if not reaching Maximum Amount
The transfer instructions are sent to block catenary system 200 thereby executing transfer operation.Otherwise, the refusal of air control platform 300 sends out the instruction
It send to block catenary system 200, and sends and notify to the terminal device of user 100 110.
To, by this way, can be effectively reduced user account it is stolen after, the burglar for stealing account is by a short time
Repeatedly transferred accounts, the risk that the account of the user is emptied.It can also be to avoid user 100 oneself due to multiple turn in a short time
Account, so as to cause loss.
It, can be in addition, air control platform 300 is in the account total amount transferred accounts in scheduled time slot for calculating user 100
The amount of money that this is transferred accounts counts, and the amount of money that this can not also be transferred accounts counts.
Still optionally further, the result for the operation of logical card being determined, and being determined according to preset rules determines
Whether the operation of block chain is sent instructions to, comprising: is determined for executing the logical account for demonstrate,proving operation within a preset time period
Logical card operation full amount whether reach third threshold value；And refusal will instruction in the case where full amount reaches third threshold value
It is sent to block chain, or sends instructions to block chain in the case where full amount is not up to third threshold value.
Specifically, air control platform 300 can parse this and refer to after the instruction for receiving the transfer operation that terminal 110 is sent
It enables, the first user 100 of analysis is to be transferred accounts by which account to second user.After obtaining the account for transferring accounts, wind
What control platform 300 can transfer accounts the account in scheduled time (such as in 24 hours, in one week or in 30 days, etc.) transfers accounts
Number whether reached and preset highest number (i.e. third threshold value).If not reaching highest number, air control platform 300
The transfer instructions are then sent to block catenary system 200 thereby executing transfer operation.Otherwise, the refusal of air control platform 300 refers to this
Order is sent to block catenary system 200, and sends and notify to the terminal device of user 100 110.
