Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further 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 invention and are not intended to limit the invention.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The method for managing and controlling address book data provided by the application can be applied to the application environment shown in fig. 1. The application environment comprises a client 101, a server 102 and a blockchain platform 103, which can form a cloud address book system. Wherein, the server 102 communicates with the client 101 and the blockchain platform 103 respectively through a network. The client 101 sends an operation request to the server 102, and the server 102 controls the blockchain platform 103 to execute a corresponding operation on the address book data and returns operation data obtained by executing the operation to the server 102. The client 101 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices; the server 102 may be implemented as a stand-alone server or a server cluster composed of a plurality of servers; the blockchain platform 103 may include a plurality of nodes therein, which may be implemented by various types of hosts.
The embodiment of the invention provides a method and a device for managing and controlling address book data, a cloud address book system, computer equipment and a storage medium. The following are detailed below.
In one embodiment, as shown in fig. 2, a method for managing and controlling address book data is provided. Taking the application of the method to the server side in fig. 1 as an example for explanation, the method comprises the following steps:
s201, receiving an operation request sent by a client; wherein, the operation request comprises data operation information; the client logs in a target user.
The client may send an operation request to the server according to the request of the application program. The application program can be IOS application, Andorid application, Web application, data analysis application and the like; specifically, the application may refer to an application corresponding to the cloud address book. Because the address book data corresponding to different applications may be different (for example, the contacts contained in the address book data are different, and the specific information formats contained in the contacts are different), an operation request may be sent by the application to the server by means of the client and the microservice gateway, so as to operate the address book data of the application.
The target user refers to a user using the current client. For example: the user A logs in an application program (the application program is used for realizing a cloud address book function and can be called as a cloud address book application program) through the mobile phone, after the application program is logged in, an inquiry control of the application program is clicked, and the mobile phone sends an operation request for inquiring address book data to the server. At this time, the user a can be regarded as the target user. In addition, an account registered by the user a on the cloud address book application may also be regarded as a target user. The related cloud address book is software for providing address book backup and recovery in order to prevent personal data loss; the address book in the mobile phone is backed up to the cloud end through the network, and then the cloud end information can be checked and managed through the mobile phone, the tablet or the computer.
The data operation information can be information for adding, modifying, updating, deleting, inquiring, checking contact consistency, verifying user identity, sequencing and the like to the address book data.
S202, sending an operation instruction to a block chain platform according to the data operation information; the operation instruction is used for triggering the block chain platform to execute corresponding operation on the address book data of the target user.
The address book data of the target user may refer to information such as names, telephones, account numbers, work units, jobs, addresses and the like of all contacts in the address book, and may also include related information of the target user. The address book data may be stored in the blockchain platform in a list form, and thus the address book data may also be referred to as an address book list in some cases.
Further, before sending the operation command to the blockchain, the blockchain platform needs to store address book data. Therefore, before S202, the client sends the address book data to be stored to the blockchain platform through the server, and the blockchain platform stores the address book data.
In some embodiments, before the step of receiving the operation request sent by the client, the method further includes: constructing target address book data according to at least one of the contact number and the contact name of a target user; and storing the target address book data through the block chain platform. The contact number, the contact name and other information are private information (sensitive information) of the user, and the private information of the user is encrypted and written into the decentralized distributed block chain (instead of the traditional data center). Therefore, any person or organization cannot read the address book data of the user unless the private key of the user is obtained or the user is authorized, and the company can be prevented from leaking or using the address book data of the user without authorization. In addition, the non-sensitive information of the number of calls, the call duration, the short call time and the like can be stored in a traditional data center (database). The block chain platform is combined with the traditional data center, the block chain is safe, a plurality of redundant backups exist, and the block chain is suitable for storing important data which occupies little storage space; the traditional data center has large storage capacity but leakage risk, is suitable for storing non-sensitive data, and thus, the mode of separately storing sensitive data and non-sensitive data can fully and reasonably utilize the existing storage resources and improve the efficiency of data storage and processing.
When the server receives the operation request, the operation on the address book data is realized through the block chain platform. On the other hand, the server in the embodiment of the invention adopts a micro-service architecture. Wherein, micro-service refers to developing a single small-sized service with business function, each service has its own processing and light communication mechanism, and can be deployed on a single or multiple servers. Micro-services also refer to a loosely coupled, service-oriented architecture with some bounded context.
For ease of understanding, the block chain technique and microservice architecture are described herein: the block chain is originated from the smart bit currency in China, is used as the bottom layer technology of the bit currency, is essentially a decentralized database, is a technical scheme for maintaining a reliable database collectively in a decentralized and trust-removing mode, and has the characteristics of open consensus, transparent transaction, anonymity of two parties, non-tampering, non-traceability and the like. For decentralization, the most important is to adopt a distributed architecture and a point-to-point transmission network mode to solve the interaction between points; for de-trust, the most important are two mechanisms: one is public/private key mechanism and one is consensus mechanism. The basic unit stored by the block chain platform is a block adopting a chain structure, namely, the newly added block records the mark of the last block. In addition, the block chain platform in the embodiment of the invention is constructed on a Kubernetes cluster, the Kubernetes cluster can run the whole block chain platform and is responsible for scheduling the docker container (the application runs on the docker container), and if some containers are found to run abnormally, tasks are automatically redeployed on other nodes, so that the automatic deployment, the elastic expansion and contraction capacity, the safety control and the operation and maintenance control of the microservice are realized, and the high availability is realized. The micro-service architecture is a distributed application technology architecture, and aims to effectively split application and realize agile development, rapid evolution, convenient fault tolerance and elastic expansion. The block chain technology and the micro-service architecture cannot be simply regarded as the combination of the micro-service and the distributed database, and the block chain platform can be used as a third-party application to interact with the micro-service, which is also the reason why the micro-service architecture can well play a role. Therefore, by combining the block chain technology with the micro-service, the decentralized cloud address book can be realized, so that the safety and the accuracy of the user address book are ensured.
Further, as shown in fig. 3, the implementation process of the blockchain technique is described below by taking bitcoin value transfer as an example: owner a signs a digital signature to the previous transaction and the next owner B using his or her private key and appends this signature to the end of the current bitcoin to make the transaction order. (B has the public key as the receiver address). A broadcasts the transaction list to the whole network, the bitcoin is sent to B, and each node incorporates the received transaction information into a block. Each node obtains the accounting right of the new block by analyzing the mathematical topic (the node repeatedly tries to find a numerical value, so that the data value, the Hash value of the last block in the block chain and the transaction list are sent to the SHA256 algorithm, and then the Hash value X can be calculated to meet certain conditions), and the node wins corresponding rewards. When one node finds a solution, all timestamp transactions recorded by the block are broadcasted to the whole network and are audited by other nodes of the whole network. The other nodes in the network check the correctness, and after no error, they add the block to the main chain and then start the next round of accounting contention.
S203, receiving operation data returned after the corresponding operation is executed by the block chain platform.
After the operation is performed, the blockchain platform may obtain corresponding operation data, such as: when the operation request is a request for inquiring the address book data, the data operation information is inquiry information of the address book data, and the obtained operation data can be the inquired address book data or information such as 'address book data inquiry success' and the like. The blockchain platform may return the obtained operational data to the server.
After receiving the operation data returned by the blockchain platform, the server can send the operation data to the client so that the client can know the operation condition of the address book data, and in addition, the client can update the related address book information in the application program according to the operation data so as to inform the user.
In this embodiment, the corresponding operation is executed through the blockchain platform, and the data involved in the operation process can be recorded through the decentralized blockchain, so that the address book data cannot be tampered, and the safety of the address book data is effectively ensured.
In one embodiment, the step of sending the operation instruction to the blockchain platform according to the data operation information includes: acquiring target address book data of a target user from a block chain platform; if the data operation information is the sequencing change information; acquiring intimacy between a target user and each contact in target address book data, and sending a sorting change instruction to a block chain platform; the sorting change instruction is used for triggering the block chain platform to change the sorting of the target address book data; the intimacy is determined according to the contact person communication information between the target user and each contact person.
In addition, if the data operation information is address book updating information; according to the address book updating information, an address book updating instruction is sent to the block chain platform; and the address book updating instruction is used for triggering the block chain platform to update the target address book data.
The step of obtaining contact person communication information between the target user and each contact person in the target address book data comprises the following steps: and acquiring at least one item of the call times and the call duration between the target user and each contact from the database as the call information of the contact.
Further, the step of calculating the intimacy between the target user and each contact according to the contact call information comprises the following steps: acquiring an intimacy reference value of a target contact person; the target contact person is any contact person in the target address book data; and calculating the weighted sum of the contact person communication information and the affinity reference value to obtain the affinity of the target user and the target contact person. Through the method, the intimacy between each contact and the target user is calculated one by one so as to facilitate subsequent address book updating operation. In particular, the calculated intimacy may be calculated in a linear or non-linear manner.
The affinity reference value can be a value defined by a user, namely, the user can define different values for each contact according to the requirement of the user so as to represent the importance. Specifically, the intimacy reference value may be 1 divided by the user-defined ranking, and if the first intimacy reference value is 1, the second intimacy reference value is 0.5, and so on. Of course, the affinity reference value may be set in other setting manners, for example, if the target user sets contact a as a common contact, and does not set contacts B and C, the affinity reference value of contact a may be considered to be 1, and the affinity reference values of contacts B and C may be considered to be 0. It should be noted that the intimacy reference value may be updated according to the needs of the user.
Specifically, the method for calculating the intimacy between the target user and a certain target contact person in a linear manner can be implemented by the following formula:
Figure BDA0002078659020000071
wherein I is intimacy, O is the frequency of clicking the detail page of the target contact by the target user, DF is the calling frequency of the last half year (called to the target contact by the target user), DTimeiFor each dialed call duration, n is the number of dialed calls in the last half year, RF is the frequency of received calls in the last half year (dialed by the target contact to the target subscriber), m is the number of received calls in the last half year, RTimeiFor each received call duration, PI is last calculated affinity, C is affinity reference value, W1、W2、W3、W4、W5、W6And W0Are weights. The magnitude relationship of the initial weights may be: w0>>W1>W2>W3>W4>W5，W6And (5) at the later stage, dynamically optimizing according to the data feedback of user-defined sequencing and the last calculated intimacy.
Of course, the statistical period of the parameters in the above formula can be replaced by other times from half a year, for example: 1 year, 1 month or 1 week. In addition, the server can calculate the intimacy according to a specific time period and automatically update the list sequence of the target address book data; this time period may be 1 year, 1 month or 1 week, and may default to 1 week.
The block chain platform can place the contact information with the higher intimacy degree in the target address book data in front of other contacts according to the currently calculated intimacy degree of each contact, so that a user can find the contact with the higher intimacy degree more quickly. And then, the block chain platform can also send address book updating information to the client through the server so as to update the address book data displayed in the client.
At present, most address lists are sorted according to the sequence of an alphabet, and if a plurality of user contacts exist, the user contacts are often difficult to find the frequently-used contacts quickly. According to the address book data management and control method provided by the embodiment, the contact persons in the address book are sorted again according to the intimacy degree, the contact persons frequently clicked, dialed and received are automatically placed at the top according to the data of the user such as the call time, the frequency and the mark, and the sorting priority of the user can be higher than the algorithm priority, so that the contact persons needing to be operated can be found by the user at the first time, the time is saved for the user, and the use efficiency of the user is improved.
In one embodiment, the step of controlling the blockchain platform to update the target address book data according to the address book update information includes: sending a modification instruction to the block chain platform according to the address book updating information; and the modification instruction is used for triggering the block chain platform to modify the original information of the corresponding contact in the target address book data.
The step may also specifically include: sending a newly increased instruction to the block chain platform according to the address book updating information; and the new adding instruction is used for triggering the block chain platform to newly add corresponding contact information in the target address book data.
The step may further specifically include: sending a deleting instruction to the block chain platform according to the address book updating information; and the deleting instruction is used for triggering the block chain platform to delete the corresponding contact information in the target address book data.
The address book update information may be information obtained by modifying or adding information of a certain contact in the target address book data, for example: modifying or newly adding the position of the contact A; new contacts can be added; some or some of the stored contact information may also be deleted.
According to the embodiment, the address book data in the address book can be modified, deleted or newly added according to the requirements of the user, so that the latest address book data is recorded in the block chain platform, and the subsequent use of the user is ensured.
In one embodiment, further comprising: if an updating instruction sent by the client is received; wherein, the updating instruction comprises updated information of the target user; sending an information updating instruction to the block chain platform according to the updated information; the information updating instruction is used for triggering the block chain platform to update the information of the target user in the associated address book data; the associated address book data is address book data corresponding to each contact in the target address book data.
Further, after a certain contact B in the target address book data logs in the application program, a prompt message of 'XX contact information updated' can be output to the contact B through the application program, and the contact B can select to update the related associated address book data at the client, so that the address book data of the client can be always kept in the latest state.
The traditional cloud address book synchronization depends on a data center, and the synchronization process of the traditional cloud address book is user A, the data center and user B, and the synchronization process highly depends on the network and storage of the data center. According to the embodiment, the centralized point-to-point network is removed through the block chain, the identity information of the contact person is synchronized more safely and reliably, the risks of information tampering and interception are avoided, and the speed and reliability of information synchronization are improved.
In one embodiment, after the step of sending the address book update command to the blockchain platform according to the address book update information, the method further includes: receiving a version recovery request sent by a client through an application program; the version recovery request comprises a version number of a target version; the target version is one of a plurality of updated target address book data; searching target address book data corresponding to the target version from the block chain platform according to the version number of the target version; sending a version recovery instruction to the client according to the target address book data; and the version recovery instruction is used for controlling the client to replace the target address book data in the application program with the target address book data. And when the user updates the address book data once, the address book data before and after updating can be used as an address book version.
According to the embodiment, the address book version after the address book is updated by the user every time is recorded, the address book of the user can be recovered according to the specified version, and the intelligence of the cloud address book system can be effectively improved.
In one embodiment, the data operation information includes address book authorization information, and the address book authorization information is used for triggering the block chain platform to acquire target address book data of a target user; the address book authorization request comprises an authorization key; verifying the authorization key; if the authorization key passes the verification, signing the authorization certificate of the target address book data and the authorized contact (namely establishing an authorization and authorization relationship between the target address book data and the authorized contact); wherein the authorization certificate is used for indicating that the authorized contact has the authority of sharing the target address book data. In addition, the authorization certificate may also be used to indicate that the authorized contact has the right to share some contact information in the target address book data, and certainly, the authorization certificate also includes related information of the target user.
The authorization key may be a private key, which may be stored by the target user, or may be stored by the server 102 or the client 101.
On the other hand, the data operation information comprises address book sharing information, wherein the address book sharing information comprises a sharing key; the address book sharing information is used for triggering the block chain platform to verify the shared key; and if the shared secret key passes the verification, acquiring the authorized address book data signed with the authorization certificate by the target user, and returning the authorized address book data. And when receiving the authorized address book data returned by the blockchain platform, the server can send the authorized address book data to the client.
Specifically, a schematic diagram of address book authorization and sharing may be shown in fig. 4, and the specific flow is as follows:
