Background
In the field of internet of things and the field of smart homes, operators providing data services build a data center of a certain area on the cloud and build a data center of another area. For example, in the china region, an operator providing data services may build a data center on public cloud platforms such as Tencent cloud and Ali cloud; in the U.S. region, the operator can also build a data center through cloud platforms such as Microsoft cloud and Amazon cloud. In addition, an operator providing data services also provides data storage services for users, and users can store business data to a data center where the users are located through clients provided by the operator, for example, users located in china can store user data to a data center in china through clients provided by the operator.
The client accesses the data center through personal data of the user, wherein the personal data can be personal data of a mobile phone number, a tripartite openId, a mailbox and the like of the user. If a user stores personal data only in a data center of one region, when the user is in another region, the data center of the other region needs to synchronize the personal data of the user with the data center which stores the personal data, so that the user can access the data center which stores the personal data on a client of the other region. For example, a data center in china area already stores personal data of a user, and when the user is located abroad, the data center in foreign country needs to synchronize the personal data of the user and an area where business data of the user is stored (i.e. china area) with the data center in china area, so as to determine that the business data of the user is stored in the data center in china area, and the user can access the data center in china area on a client in foreign country.
However, since the personal data of the user relates to the privacy of the user, the cross-region synchronization of the personal data of the user is restricted by law under the above-mentioned scenario, and the cross-region synchronization of the personal data of the user has an illegal phenomenon and is not in accordance with the legal regulations. In addition, the cross-region synchronization of the personal data of the user also has the risk of privacy disclosure, which is not favorable for personal privacy security.

Detailed Description
The embodiment of the application provides a data center access method, a client and a computer storage medium, which are used for solving the problems of violation and privacy security caused by cross-region synchronization of personal privacy data.
Referring to fig. 1, the network framework in the embodiment of the present application includes:
a client 101 and data centers 102-103;
the client 101 and the data centers 102 to 103 can establish communication links based on a wireless network or a wired network respectively. The wireless network may be a cellular wireless network, a WiFi network, or other wireless network. The type of wired network is typically a fiber optic network.
The data centers 102-103 are built on a cloud platform for providing data services, and can be cloud servers for providing basic cloud computing services such as a cloud database, cloud computing, big data and artificial intelligence platforms and the like. In a specific application scenario, the data centers 102 to 103 may also be data rooms configured with a plurality of cloud servers. In addition, when an operator providing data services builds a data center, in order to enable the data center to provide services for users in different regions, the data center can be built in different regions of the world so as to meet the user requirements of each region, and then the data centers 102-103 can be distributed in different regions.
An operator providing a data service develops a client 101 for providing the data service to a customer, and the user can install and use the client 101 on a terminal device. The terminal device may be a terminal device such as a smart phone, a Personal Computer (PC), a desktop computer, a tablet PC, a computer all-in-one machine, and a wearable electronic device.
It should be noted that, the network framework only lists one client and 2 data centers, but in practical applications, the network framework may also have more clients and data centers participating.
The following describes a data center access method in the embodiment of the present application with reference to the network framework of fig. 1:
referring to fig. 2, an embodiment of a data center access method in the embodiment of the present application includes:
201. acquiring a feature code index provided by a local data center;
the method of the embodiment can be applied to the client in the foregoing network framework, and the client is in communication connection with the local data center where the client is located.
The user needs to access the data center storing the user service data through the client, but the client cannot know the domain name or the address of the data center storing the user service data, that is, the client cannot determine which data center should be accessed.
The specific scheme is that the client acquires a feature code index provided by a local data center, the feature code index comprises a corresponding relation between a feature code and the data center, and the feature code is obtained by converting personal data of a user according to a feature code conversion algorithm.
For example, the feature code index may display that the feature code of user a corresponds to data center 1, the feature code of user B corresponds to data center 2, the feature code of user C corresponds to data center 3, and so on.
The personal data of the user refers to data related to the personal privacy of the user, and may be sensitive data such as a mobile phone number, a mailbox, a tripartite openId, a login password, and a personal identification number of the user. The business data of the user stored in the data center refers to data related to daily business of the user, for example, data related to business such as daily work and study of the user.
202. Acquiring a target feature code of a target user, inquiring a target data center corresponding to the target feature code in the feature code index, and accessing the target data center;
when a target user initiates a request for accessing a data center, a client acquires a target feature code of the target user and queries a target data center corresponding to the target feature code in a feature code index. After the target data center is determined, the client acquires the domain name and the address of the target data center, so that the target data center can be accessed according to the domain name and the address, and a user can read and operate the service data stored in the target data center through the client.
In this embodiment, the client acquires the feature code index, and when a target user initiates a request for accessing the data center, the client acquires the target feature code of the target user, queries the target data center corresponding to the target feature code in the feature code index, and initiates access to the target data center. The characteristic code of the user is obtained by converting the personal data of the user through the characteristic code conversion algorithm, so that the characteristic code does not relate to the personal privacy of the user, the user privacy cannot be leaked even if the characteristic code is transmitted among a plurality of devices, the personal data of the user does not need to be transmitted across a plurality of data centers, the safety of the user privacy is ensured, the legal regulation is met, and the violation phenomenon cannot occur.
The embodiments of the present application will be described in further detail below on the basis of the aforementioned embodiment shown in fig. 2. Referring to fig. 3, another embodiment of the data center access method in the embodiment of the present application includes:
301. acquiring a feature code index provided by a local data center;
in this embodiment, the feature code index includes a corresponding relationship between the feature code and the data center, where the data center having a corresponding relationship with the feature code is a data center that has stored the service data of the user, and the target data center is a data center that has stored the service data of the target user.
For example, the feature code index may show that the feature code of the user a has a corresponding relationship with the data center 1, and then the data center 1 stores the service data of the user and is also a data center that the user a needs to access.
The characteristic code indexes can be deployed in data centers of different regions, namely the characteristic code indexes are deployed in each data center and are synchronous among the data centers, so that the client can determine a local data center closest to a target user according to one or more items of position information of the target user and an IP address of equipment where the client is located, and establish a communication link with the local data center, so that the client does not need to access each data center in a traversing manner to obtain the characteristic code indexes, the access operation of the client is reduced, the processing resources of the client are saved, and the processing efficiency of the client is improved.
The location information of the target user may be a time zone of an area where the target user is located, or may be specific location information of the area where the target user is located.
In addition, the data center to which the client needs to be connected in communication can be determined according to the country code input by the user on the client, and the data center to which the client needs to be connected in communication can be determined according to a telecommunication operator providing telecommunication service for the user. Meanwhile, the user may also default to a data center that needs communication connection, which is not limited in this embodiment.
The feature code conversion algorithm may be any algorithm capable of converting the personal data of the user into the feature code, and may be a feature code calculation function, that is, the personal data of the user is input into the feature code calculation function to be calculated, and then the feature code is output. For example, the mobile phone number of the user is input to the feature code calculation function to calculate and obtain the corresponding feature code. In addition, the personal data used for calculating the feature code may also be information such as a mailbox, a user name, a three-party openid, and an equipment identifier, where the equipment identifier refers to an identifier of equipment used by a user, and may be a MAC address of a computer, an IMEI code of a mobile phone, or an identification code having uniqueness assigned by an operator providing data services to a client.
The feature code conversion algorithm may be customized by human, or may be a hash algorithm such as MD5 algorithm, SHA algorithm, or the like, as long as the algorithm can calculate and convert the personal data of the user to obtain the feature code, and the specific type of the algorithm is not limited.
For example, the signature conversion algorithm may be an HMAC algorithm, i.e., a key-dependent Hash authentication code (Hash-based message authentication code). The expression of the HMAC algorithm formula is as follows:
where H refers to a hash function (e.g., SHA family hash algorithm); k denotes a key (secret key); m denotes a message to be authenticated; k' refers to another secret key derived from the original key K (Padding) zeros to the right if K is shorter than the input block size of the hash function; hashing K if longer than the block size); | | refers to concatenation;
refers to exclusive or operation (XOR); opad refers to outer padding (0x5c5c5c … 5c5c, a piece of hexadecimal constant); ipad refers to an inner fill (0x363636 … 3636, a piece of hexadecimal constant).
When the feature code is calculated according to the HMAC algorithm, the feature code can be calculated by substituting the user-defined key string secret key and personal data (such as personal data of a user name, a three-party openid, a mobile phone number and the like) of the user into an HMAC calculation formula. The message digest algorithm of the HMAC algorithm can adopt MD or SHA two large series algorithms, and the MD series algorithms can be algorithms such as HmacMD2, HmacMD4, HmacMD5 and the like; the SHA series algorithms may be algorithms HmacSHA1, HmacSHA224, HmacSHA256, HmacSHA384, HmacSHA512, and so on.
In addition, the signature may also be calculated in a Hash-plus-salt manner, i.e. the signature is Hash ("personal data of the user" + salt "). The personal data of the user can be personal data such as a user name, three-party openid, a mobile phone number and the like; salt is an encrypted string that prevents the feature code from being calculated. The Hash algorithm can adopt the Hash algorithms such as MD5, SHA-256, SHA-512 and the like.
302. Determining a data center for storing business data of a target user according to one or more items of a registration area of a registration account of the target user on a client, business requirements of the target user and agreement terms signed by the target user and the client;
in the scenario of this embodiment, the target user may register an account on the client in advance. And at the same time of registering the account, the client also determines a data center required for storing business data of the target user. The data center required to store the service data of the target user may be determined according to a registration area of a registration account of the target user, for example, if the target user registers an account in a china area through a client, the data center in the china area may be determined as the data center for storing the service data of the target user; another way may also be that, the determination is made based on the service requirement of the target user, for example, if the service processing of the target user is basically located in a china region, the data center in the china region may be determined as the data center for storing the service data of the target user; the data center of the china area may be determined as the data center for storing the business data of the target user, for example, if the agreement term shows that the target user agrees to use the data center of the china area as the data center for storing the business data of the target user.
303. Acquiring a target feature code of a target user, inquiring a target data center corresponding to the target feature code in the feature code index, and accessing the target data center;
in this embodiment, a plurality of feature code conversion algorithms may be used to calculate the feature code of one user, respectively, that is, each feature code conversion algorithm is used to calculate one feature code, so as to obtain a plurality of feature codes of the user. Moreover, a plurality of feature codes of one user may only correspond to one data center, and the feature code index further includes a corresponding relationship between the plurality of feature codes and one data center. Each user corresponds to a plurality of feature codes, so that feature code repetition among users can be prevented, because the feature codes of the users are calculated by only using one feature code conversion algorithm, the feature code repetition among the users can be caused, and when the feature codes are repeated, which user corresponds to the feature codes can not be determined according to the feature codes. When each user corresponds to a plurality of feature codes, the probability of the repetition of the plurality of feature codes among the users is much smaller, so that the repetition of the feature codes can be avoided when each user corresponds to the plurality of feature codes, and the determination of the user corresponding to the feature codes is facilitated.
Therefore, in this step, any one or more of the target feature codes of the target user are obtained, and the plurality of target feature codes are obtained by converting with different feature code conversion algorithms respectively. And then, inquiring a target data center corresponding to any one or more target characteristic codes in the characteristic code index, further determining the domain name and the address of the target data center, and initiating access to the target data center according to the domain name and the address.
In the embodiment, personal data and service data of the user do not need to be transmitted among a plurality of data centers, and privacy safety and data safety of the user are ensured.
