All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without inventive step, are within the scope of the present disclosure. Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an exemplary embodiment of the present disclosure, there is provided a platform fund account management method in which a user operation request is a recharge request, as shown in fig. 1, the method includes the following steps:
step S102, a user initiates a user operation request.
In an exemplary embodiment of the disclosure, a client device, such as a mobile phone APP, sends a user operation request, such as a recharge request, to a platform fund account management system.
And step S104, generating a recharging order and returning a payment link.
And the platform fund account management system calls an interface of the platform fund account management system to generate a recharge order and returns a payment link.
Step S106, the user pays the recharge amount.
After receiving the payment operation of the user, the bank system or the third-party payment system judges whether the amount of money in the account of the user is larger than or equal to the amount of money to be paid by the user, if so, the amount of money to be paid by the user can be directly deducted from the bank account provided by the user and added to a platform account in the bank system or the third-party payment system, and meanwhile, the user is prompted to be charged successfully, otherwise, the user is prompted to be insufficient in balance.
In consideration of the safety management of funds, a front-end server and a platform fund account management system are generally set by a bank system or a third-party payment system to correspond to each other, the front-end server and the platform fund account management system are connected through the internet to receive various requests sent by the platform fund account management system, and then corresponding deduction processing is performed on a recharged account by a background server.
In an exemplary embodiment of the disclosure, the front-end server is further configured to preprocess data of the payment application sent by the platform fund account management system, and verify the validity of the data.
In addition, the platform fund account management system and the bank system or the third-party payment system are in agreement of safety communication of the two parties in advance. For example, the banking system or the third party payment system pre-deploys the enterprise internet banking client of the platform fund account management system, the hardware certificate, and the user and password of the operator. The enterprise online bank client and the hardware certificate are used for enabling interactive communication between the third-party payment platform and the platform fund account management system to be safer. The user of the operator and the password are set for manual review.
And step S108, after the recharging is successful, updating the balance of the user.
And the bank system or the third-party payment system informs the platform of the fund account management system after the user successfully charges. The platform fund account management system adds a recharging amount to the balance of the user or the balance of the special account of the special fund and updates the state of the recharging order.
According to an exemplary embodiment of the present disclosure, a platform fund account management method for a user operation request being a transfer request is provided, as shown in fig. 2, the method includes the following steps:
in step S202, a user initiates a user operation request.
In one exemplary embodiment of the disclosure, a client device, such as a cell phone APP, sends a user operation request, such as a transfer request, to a platform funding account management system. In the transfer request, the user designates a transfer account number and a target account number of the initiating user and a transfer amount.
Step S204, checking whether the transfer is in compliance.
And checking whether the transfer is in compliance according to the information provided by the user. After the transfer compliance is verified, it is determined whether the user balance for the user in the platform funding account management system is greater than the transfer amount.
And if the balance of the user is less than the transfer amount, reminding the user to recharge. The user transfers money to the bank account of the platform in the bank system or a third-party payment system through other payment methods, and simultaneously the platform records the amount of money and displays the money to the user in a 'wallet' or 'balance'.
And if the balance of the user is larger than the transfer amount, deducting the transfer amount from the account balance of the initiating user in the platform fund account management system, and increasing the transfer amount in the account balance of the target user.
In an exemplary embodiment of the present disclosure, after consumption between users, the amount of money is not entered into the user's bank account, but is recorded on the platform fund account management system.
Step S206, the user is informed that the transfer is successful.
And the platform fund account management system informs the user of successful transfer after the user transfers money successfully.
According to an exemplary embodiment of the present disclosure, a platform fund account management method for a user operation request being a cash-out request is provided, as shown in fig. 3, the method includes the following steps:
step S302, a user initiates a user operation request.
In an exemplary embodiment of the disclosure, a client device, such as a cell phone APP, sends a user operation request, such as a cash-out request, to a platform funding account management system.
And calling a platform capital account system interface to generate a cash withdrawal order.
And step S304, cash withdrawal is carried out.
And the platform fund account management system calls a transfer interface of a bank system or a third-party payment system to transfer the withdrawal amount from the platform account to the account specified by the user.
And step S306, informing the user of successful cash withdrawal.
And after the user successfully finds the fund account management system, correspondingly deducting the user balance under the user account in the system, and informing the user of successful finding.
According to an exemplary embodiment of the present disclosure, there is provided a platform fund account management method for a user operation request being a consumption request, as shown in fig. 4, the method includes the following steps:
in step S402, the user initiates a user operation request.
In an exemplary embodiment of the disclosure, a client device, such as a cell phone APP, sends a user operation request, such as a consumption request, to a platform funding account management system. In the transfer request, the user specifies the amount of consumption.
In step S404, the consumption amount is deducted.
When a user purchases the service provided by the platform, the balance of the user's own account is consumed, and the amount consumed by the user is transferred from the balance of the user to the platform account.
In an exemplary embodiment of the present disclosure, the platform fund account management method may provide reconciliation, system monitoring processing, log processing, and the like, in addition to the above-described recharge processing, transfer processing, cash withdrawal processing, and consumption processing.
In order to ensure platform fund security, in the embodiment of the disclosure, platform individual accounts, platform total account entry, balance and account withdrawal are checked and monitored, so that the account entry, balance and account withdrawal amount of a single account are consistent, the account entry, balance and account withdrawal amount of the whole system are consistent, and the fund security problem is avoided. In addition, in order to ensure the normal operation of the user transaction, the performance of the system, the transaction delay, the third-party service and other related indexes are monitored, so that whether the transaction is normal or not, whether the system platform is stable or not and whether a third-party support channel is very stable or not are monitored.
In an exemplary embodiment of the present disclosure, in consideration of the problem that a database is tampered with by being attacked, the present disclosure performs encoding processing on a user operation request.
With the rapid development of internet technology, the application of enterprise databases is very wide, and the enterprise databases go deep into various fields, but the security problem of data is generated therewith. Security of a large amount of data in databases of various application systems, and theft and tamper prevention of sensitive data are increasingly attracting great attention.
The types of hacking databases are commonly known as SQL injection and the like. In some cases, if the attacker gets a screen of an application that requires the entry of a username and password, and the application does not check the contents of the login, all he needs to do is provide an SQL statement or database command and go directly to the database. At this time, a user name is not inputted, but an SQL command is inputted. It is entered into a data packet and sent by the application server to the database. This database would read the fraudulent SQL command, and at this time, the database would execute no matter what the SQL command executed.
The method and the device have the advantages that in order to prevent SQL injection attack vulnerability in the application program, real data of certain databases are prevented from being displayed, and therefore potentially sensitive data information can be prevented from being disclosed to potential attackers.
Fig. 5 is a flowchart of a method of encoding a user operation request according to an embodiment of the present disclosure. As shown in fig. 5, the method comprises the steps of:
step S502, adaptive encoding processing.
In an exemplary embodiment of the present disclosure, the encoding is performed on a block basis. That is, the data stream requested by the user operation is encoded in units of blocks. The encoding in units of blocks does not encode the blocks completely independently of each other. Encoding parameters may be set to set the manner in which each sample array region corresponding to each block is encoded.
In an exemplary embodiment of the present disclosure, the user operation request is divided into blocks arranged regularly in a non-overlapping, mutually adjacent manner, and each block has division information associated therewith. Based on the division information, the user operation request is divided into blocks of different sizes according to a rule. There are different possibilities regarding the order of the elements describing the saliency and the saliency transform vector values.
