step 1 b: according to historical fund outflow information of a plurality of users and corresponding historical expression data, a neural network model for identifying the risk level of fund outflow is constructed;
step 1 c: dividing historical fund outflow information of a plurality of users and corresponding historical expression data into a training set and a verification set according to a preset proportion;
step 1 d: and training and optimizing the constructed neural network model by utilizing the training set and the verification set to obtain a risk identification model.
Wherein the historical fund flow information at least comprises: historical fund flow accounts, historical fund flow amounts, historical fund flow times, account stars, and historical fund flow risk levels. In specific implementation, in order to improve the accuracy and precision of the determination result, the historical fund flow-out information may further include: historical fund flow location, historical account balance, and the like. The risk identification model performs characteristic processing based on historical fund transaction information of a plurality of customers and historical expression data of each transaction, and determines the internal relation among the historical expression data, the fund transaction information and the risk identification result of the transaction. In the specific embodiment, a three-layer neural network is established, and the optimal individual output by a genetic algorithm is used as an initial weight and a threshold of the neural network to train and learn the neural network. The preset ratio of training set to validation set may be, for example, 7:3 or 6:4, etc. When the user conducts fund business outflow, the risk existing in the current business can be obtained through the risk identification model, the risk condition is informed to the user, and the user makes a decision whether to continue operation or not.
And an emergency fund association mechanism also exists between the sub-account and the main account, and is used for calling the pre-stored sub-account fund to be transferred into the main account and informing the sub-account when the fund amount of the main account does not meet the amount of the fund flow-out service request.
When the amount of the capital of the main account does not meet the amount of the capital outflow service request, judging whether the type of the inflow account is a public account, if so, allowing to call the prestored sub-account funds to transfer to the main account and informing the sub-account; otherwise, calling the pre-stored sub-account funds to transfer to the main account and informing the sub-account after the sub-account is authorized.
The invention also includes releasing the deposit statement dynamic change information to the main account periodically and forming a dynamic icon for displaying; the deposit receipt dynamic change information comprises daily live/regular money amount, interest amount and regular interest date. The deposit receipt dynamic change information also comprises regular observation period information, wherein the observation period is a locking period, and cannot be obtained within the period, and the regular observation period information specifically comprises observation period information, release date countdown and expiration automatic short message reminding. For example, a user may store a deposit slip, and when the deposit slip is stored in the lock period, the deposit slip is not available within 1 month if the lock period is 1 month. The traditional design mode only shows the current unavailable state, but does not show that the current unavailable state can be obtained in a specific certain day in a certain month after 1 month, and the open obtaining time is several days.
The beneficial effects of the whole are as follows: the invention provides a customer fund state tracking design method based on time axis change, which can monitor the abnormal condition of fund outflow, start an account emergency supervision process when the abnormal condition occurs, and transact fund outflow business by verifying the consistency of the biological characteristics of a user and a reserved code. When the deposit receipt is displayed, the current and future states of the deposit receipt can be displayed, and meanwhile, the deposit receipt dynamic change information is published periodically and dynamic icons are formed for displaying.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
