Detailed Description
In order to make the purpose, technical solution and beneficial effects of the present application more clear and more obvious, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
First, some terms referred to in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.
The terminal equipment: the electronic device can be mobile or fixed, and can be used for installing various applications and displaying objects provided in the installed applications. In the embodiment of the application, the terminal device is mainly a user terminal or an access terminal.
An outer net: the Internet is a collection of computer networks that interconnect computer networks (including local area networks, metropolitan area networks, and wide area networks) at different locations around the world, and on a varying scale.
Network security domain: the general implementation method is implemented by adopting a firewall to be deployed at a boundary, and controlling which Internet protocols (Internet protocols, IP) are allowed to access the domain and which are not allowed to access the domain through a firewall policy; which IP/network segments this domain is allowed to access and which IP/network segments it is not allowed to access. Through the network security domain, the security of the equipment can be improved.
Script: the method is an extension of batch processing data, is a pure text storage program, is a combination of a determined series of operation operations performed by a control computer, and can realize certain logic branches and the like.
The design concept of the embodiment of the present application is described below.
With the development of internet technology, data becomes an important core asset, and the security requirements of people on data storage and access are higher and higher.
In the embodiment of the present application, data protected by PCI DSS is taken as an example for description. The purpose of the PCI DSS is to secure the information of the cardholder's credit and debit cards. For example, the security data protected by the PCI DSS specification may be user's certificate photo data. In the prior art, the following methods are generally adopted for storing and accessing secret data:
the user terminal uploads the secret data to any one of a plurality of internet servers located in an external network, and the internet servers encrypt and store the received secret data. The access terminal accesses the data application in each of the internet servers in turn to determine the internet server on which the confidential data is stored. And the internet server decrypts the confidential data requested by the access terminal and returns the decrypted confidential data to the access terminal.
However, since the confidential data is stored in a plurality of internet servers in a distributed manner and the access terminal accesses the data application in each internet server in turn, the data access efficiency is low. Moreover, because the security of the external network is low, the internet server decrypts the confidential data and transmits the decrypted confidential data, so that the potential safety hazard of the confidential data is high. Further, when the internet server changes (such as capacity expansion or capacity reduction), the access terminal needs to configure corresponding access device information, and the configuration steps are complicated, which brings inconvenience to the user.
Therefore, how to improve the security and the access efficiency of data storage and access is an urgent problem to be solved.
In view of the above, the applicant considers that the data in each internet server can be stored in a data management server in the network security domain in a centralized manner, so as to improve the security and access efficiency of data storage and access.
In view of the above analysis and consideration, the present application provides a data storage and access scheme, in which encrypted data of specified types of data is centrally stored in a data management server located in a network security domain, and the data management server obtains corresponding encrypted data from a local data storage pool according to a received data request message of an access terminal, and returns decrypted data obtained by decrypting the encrypted data to the access terminal.
To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide method steps as shown in the following embodiments or figures, more or fewer steps may be included in the method based on conventional or non-inventive efforts. In steps where no necessary causal relationship exists logically, the order of execution of the steps is not limited to that provided by the embodiments of the present application. The method can be executed in sequence or in parallel according to the method shown in the embodiment or the figure when the method is executed in an actual processing procedure or a device.
Referring to fig. 1, a schematic diagram of an architecture of a data storage and access system is shown. The system comprises: a plurality of user terminals 10, a plurality of internet servers 11, a data management server 12, and a plurality of access terminals 13.
The user terminal 10 has a terminal application installed therein, and is configured to obtain information input by a user and uploaded data through the terminal application, and present corresponding page information to the user through a terminal application page. For example, the terminal application is a payment application, and the uploaded data is certificate photo data.
Each internet server 11 is located on the external network and is provided with a synchronization script for encrypting received data and synchronizing the data.
The security of the internet server 11 is low since any user can access the devices in the external network.
The data management server 12 is located in a network security domain and is provided with a data storage pool for storing data, for storing data centrally, and for decrypting data.
Wherein, the access terminal 13 is installed with an access application for acquiring data in the data management server 12 through the access application.
In the embodiment of the application, the data of different internet servers 11 which are dispersedly stored in the external network are intensively stored in the data management server 12 of the network security domain, so that the complicated step that each internet server 11 needs to be inquired in sequence to obtain the data is avoided, and the data access efficiency is improved; moreover, the data management server in the network security domain carries out decryption transmission instead of the internet server of the external network, so that the security of data access is greatly improved. Furthermore, the deployment of the internet server and the access terminal is decoupled, and the complicated configuration steps of the access terminal when the internet server is changed are reduced.
It should be noted that the embodiments of the present application are mainly applied to an application scenario of storing and accessing data that needs to ensure data security, for example, storing and accessing confidential data protected by the PCI DSS specification.
Referring to fig. 2, a flowchart of an implementation of a data storage method provided in the present application is shown. The method comprises the following specific processes:
step 200: the user terminal obtains the specified type data submitted through the terminal application page.
Specifically, a terminal application is installed in the user terminal, the user uploads data of a specified type through the terminal application, and the terminal application responds to data submission operation for a terminal application page and acquires the data of the specified type.
The specified type of data is data which needs to guarantee data security, that is, data which has a high requirement on the security level of the data. Optionally, the specified type of data is data protected by the PCI DSS specification, i.e. secret data.
Further, when the specified type data acquired by the user terminal does not meet the preset data condition, the data uploading failure indication information is presented through the terminal application page.
The preset data condition may be set according to an actual application scenario, and is not limited herein.
In one embodiment, the preset data condition is: the data capacity of the specified type data is not less than 0 k.
Step 201: and the user terminal uploads the specified type of data to the Internet server through an encryption transmission protocol.
Specifically, when step 201 is executed, in order to ensure the security of data transmission, the user terminal sends the specified type of data to the internet server of the external network through the encrypted transmission protocol.
Alternatively, the encrypted transmission protocol may be a hypertext transfer protocol over Secure Socket Layer (HTTPS).
Step 202: and the Internet server encrypts the received data of the specified type to obtain encrypted data.
Step 203: the internet server synchronizes the encrypted data to the data management server.
Specifically, the internet server synchronizes the received encrypted data to the data management server in real time or periodically through the deployed synchronization script, and stores the encrypted data to the local.
Optionally, the synchronization Script may be developed by using languages such as Hypertext Preprocessor (PHP) and parsing-type service terminal (VBScript), which is not limited herein.
That is to say, a synchronous script is deployed in the internet server, and when it is determined that new encrypted data exists through the synchronous script, the new encrypted data is sent to the data management server in real time, or the new encrypted data is sent to the data management server according to a preset time length.
The preset time duration may be set according to an actual application scenario, for example, 1 minute, and is not limited herein.
In one embodiment, the internet server obtains a first data list of the local specified data directory and a second data list of the specified data directory in the data management server through a synchronization script, and performs data synchronization according to data difference between the first data list and the second data list. And when the internet server determines that the data synchronization fails, the data synchronization is performed again according to the data difference between the first data list and the second data list, so that the complete synchronization of the data is realized through data retransmission.
Step 204: the data management server receives the encrypted data and stores the encrypted data to the data storage pool.
Specifically, when step 204 is executed, the data management server may adopt the following steps:
acquiring identification information of received encrypted data, and updating historical data into the encrypted data when the historical data corresponding to the identification information is stored in the data storage pool; and when the history data corresponding to the identification information is not stored in the data storage pool, adding the encrypted data into the data storage pool.
Wherein a storage pool is a set of disks in a server used to store the copy, the shadow copy, and the transfer log. The identification information is used to identify the encrypted data, and may be information such as a data name and a code of the encrypted data.
For example, the encrypted data is the encrypted data of the certificate photo file of the user S, and the identification information is the identification number of the user S, so that when the user S uploads the updated certificate photo file again, the data storage pool updates the encrypted data of the stored corresponding history certificate photo file according to the identification number of the user S.
Therefore, the data in each internet server can be stored in a data management server in the network security domain in a centralized manner, and the corresponding encrypted data can be updated according to the identification information of the encrypted data.
Referring to fig. 3, a flowchart of an implementation of a method for accessing data provided by the present application is shown. The method comprises the following specific processes:
step 300: the access terminal sends a data request message to the data management server.
Specifically, the access terminal sends a data request message containing user identification information to the data management server.
The user identification information may be a code or a name, and the like, for example, the user identification information may be a nickname, an account number, a certificate number, or the like of the user, and is not described herein again.
Step 301: the data management server obtains the received data request message and obtains the requested encrypted data from the data storage pool.
Specifically, the data management server receives the data request message, acquires the user identification information contained in the data request message, and searches the encrypted data corresponding to the user identification information from the data storage pool according to the user identification information.
Step 302: and the data management server decrypts the encrypted data to obtain decrypted data.
Step 303: and the data management server returns the decrypted data to the access terminal.
Specifically, the data management server encodes the decrypted data according to a specified encoding mode, and returns the encoded decrypted data to the access terminal.
The specified encoding manner may be set according to an actual application scenario, for example, the specified encoding manner may be BASE64 encoding, which is not described herein again.
In a traditional mode, encrypted data are usually decrypted and transmitted through an internet server located in an external network, and the internet server is located in the external network, so that the potential safety hazard of the internet server is large, the decrypted data stored in the internet server are easy to steal, tamper or destroy, and further, the decrypted data are easy to steal, tamper or destroy in the process of being transmitted from the internet server in the external network to an access terminal.
In the embodiment of the application, the implementation method of the network security domain is implemented by adopting a firewall to be deployed at the boundary, and the firewall policy controls which Internet Protocol (IP) is allowed to access the domain and which is not allowed to access the domain; which IP/network segments this domain is allowed to access and which IP/network segments it is not allowed to access. Therefore, as long as the access terminal is allowed to access the data management server through firewall policy control, the access terminal can access the data management server, the data management server located in the network security domain decrypts and transmits the encrypted data, the security of data storage and data access is high, and the potential safety hazard is greatly reduced.
Step 304: the access terminal presents the received decrypted data.
Specifically, the access terminal presents the received decrypted data through an access application page of the access application.
It should be noted that, in order to further improve the security of the decrypted data, the decrypted data cannot be downloaded through the access application. The access application cannot download and store the decrypted data, that is, the access application does not set a function of downloading the decrypted data, and the user can only view the decrypted data by accessing the application page, but cannot download the decrypted data by accessing the application.
In one embodiment, the access application is an application for data auditing of an auditor, and returns auditing failure indication information to the user terminal in response to an auditing failure operation for an access application page. And when the user terminal receives the data auditing failure message, presenting data auditing failure indication information to the user through the terminal application page.
Referring to fig. 4, an interactive flowchart of a method for storing and accessing data provided by the present application is shown. The method comprises the following specific processes:
step 400: the user terminal obtains the specified type data submitted through the terminal application page.
Specifically, when step 400 is executed, the specific steps refer to step 200 described above.
Step 401: and the user terminal uploads the specified type of data to an Internet server through an encryption transmission protocol.
Specifically, when step 401 is executed, the specific steps refer to step 201 described above.
Step 402: and the Internet server encrypts the received data of the specified type to obtain encrypted data.
Specifically, when step 402 is executed, the specific steps refer to step 202 described above.
Step 403: the internet server synchronizes the encrypted data to the data management server.
Specifically, when step 403 is executed, the specific steps refer to step 203 described above.
Step 404: the data management server receives the encrypted data and stores the encrypted data to the data storage pool.
Specifically, when step 404 is executed, the specific steps refer to step 204 described above.
Step 405: the access terminal sends a data request message to the data management server.
Specifically, when step 405 is executed, the specific steps refer to step 300 above.
Step 406: the data management server obtains the received data request message and obtains the requested encrypted data from the data storage pool.
Specifically, when step 406 is executed, the specific steps refer to step 301 above.
Step 407: and the data management server decrypts the encrypted data to obtain decrypted data.
Step 408: and the data management server returns the decrypted data to the access terminal.
Specifically, when step 408 is executed, the specific steps refer to step 303 described above.
Step 409: the access terminal presents the received decrypted data.
Specifically, when step 409 is executed, the specific steps refer to step 304.
A specific application scenario is adopted below, and the conventional manner is compared with the present application.
The application scene is as follows: before using the payment service, according to the supervision requirement, the user identity needs to be authenticated, and the user needs to upload secret data to an internet server of an external network to perform a job completion survey (CDD) of the individual user. The auditor needs to obtain the confidential data through the access terminal, so that the confidential data of the user can be audited according to the information filled by the user.
It should be noted that, in practical applications, according to the requirement of PCI DSS, in order to protect information security, confidential data cannot be stored in plaintext and must be uploaded to an internet service (e.g., a server in a certain country) of an external network, and the internet service needs to be able to be stored for at least a specified time (e.g., 3 years), the number of internet servers is usually multiple and all are located in the external network, the access terminal is located in the internal network, and the access terminal and the internet server are located in different systems.
Fig. 5 is a schematic diagram of a system architecture for secure data storage and access in the prior art. The system comprises: the system comprises a user terminal, a plurality of internet servers positioned on an external network and an access terminal.
In the conventional technology, a user uploads CDD information to an internet server through a terminal application of a user terminal. And the Internet server encrypts and locally stores the received CDD information. Wherein the CDD information comprises secret data. Different CDD information is stored in different internet servers in a scattered mode. And sequentially inquiring the proxy application of each Internet server by an auditor through the access terminal until the Internet server storing the target confidential data is determined. And the Internet server decrypts the target confidential data and returns the decrypted data to the access terminal so as to facilitate the audit of auditors.
Obviously, in the conventional mode, the access terminal needs to sequentially access the proxy application in each internet server in the external network, which consumes a large amount of data access time and has low system stability, and moreover, the internet server decrypts and transmits the encrypted data in the external network, so that the risk of information leakage is extremely high and great potential safety hazard is caused; further, when the internet server is changed, such as capacity expansion, the access terminal needs to reconfigure the accessed device information, which makes the operation steps cumbersome.
Fig. 6 is a schematic diagram of a system architecture for secure data storage and access according to an embodiment of the present application. The system comprises: the system comprises a user terminal, a plurality of internet servers located in an external network, a data management server located in a network security domain and an access terminal.
The specific steps of the storage and the access of the secret data are as follows:

FIG. 7d is a diagram illustrating an example of a submit confirmation page. FIG. 7e is a diagram illustrating an example of a successful page commit.
For example, the user terminal submits a CDD request on the terminal application page of the terminal application, which jumps to the profile page shown in fig. 7 a. The personal data in fig. 7a includes: name, gender, nationality, date of birth, and address.
After the user completes the personal data, the user clicks the "next" button, and the terminal application jumps to the identity authentication page shown in fig. 7b in response to the next operation on the personal data page. The identity authentication page comprises a certificate type, a certificate number, an identity card photo and the like. When the user clicks "add id photo", the authentication page jumps to the upload page shown in fig. 7 c. Wherein, the identification card photo is secret data.
The uploading page is used for uploading photos, and comprises correct example information and error example information. When the user clicks the "upload photos" button, the upload page jumps to the submit confirmation page shown in FIG. 7 d. When the user clicks the ok button, the submit confirmation page jumps to the submit success page shown in fig. 7 e.
S601: and the user terminal uploads the confidential data to an internet server through an encryption transmission protocol.
When S601 is executed, a Common Gateway Interface (CGI) may be used to upload data. The CGI is physically a program running on the server that provides an interface to the client HTML page. The CGI is the specification of an external program when the server runs, and the program written by the CGI can expand the functions of the server. The CGI application program can interact with the browser and can also communicate with an external data source such as a database server through a database interface to acquire data from the database server.
