Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the protection scope of this application.

Please refer to FIG. 1. FIG. 1 shows an application environment of the data restoration method provided by an embodiment of the present application. The data restoration method is applied in a data restoration scenario after the data of a smart device is abnormally lost. The data restoration scenario includes a server and a client. The server and the client are connected through a network. The server includes a cloud server. The client sends a data restoration request containing the initial data identifier to the server. The initial data identification included in the data restoration request performs data restoration/recovery. The client can be, but is not limited to, various personal computers, netbooks, tablet computers, smart phones and other smart devices, and the server can be implemented by an independent server or a server cluster composed of multiple servers.

Please refer to FIG. 2. FIG. 2 shows a data restoration method provided by an embodiment of the present application. The method is applied to the server in FIG. 1 as an example for description. The details are as follows:

S10: If the data restoration request sent by the client is received, the initial data identifier included in the data restoration request is obtained.

Specifically, in the process of file operations, the client has some misoperations (such as accidental deletion of files, direct exit of unsaved files, etc.), or some unexpected situations (such as sudden power failure, system failure, etc.) When the file needs to be restored, the client sends a data restoration request containing the initial data identification to the server. The server receives the data restoration request and obtains the initial data identification to perform subsequent data restoration processing based on the initial data identification. .

Wherein, the initial data identifier is a data identifier used to identify the data to be restored in this embodiment, and the client user first selects the initial data identifier according to preset conditions before sending a data restoration request through the client.

The initial data identification can be selected according to actual needs, such as file name, file type, etc. The expression form of the initial data identification can specifically be one or more combinations of words, letters, numbers, and symbols, which is not limited here.

It should be noted that the initial data identifier can specifically be a file. For example, the initial data identifier "123.txt" means that the file name is "123" and the file type is a txt file, or it can be a type of file, such as , The initial data identifier "*.doc" means that the file type is all files in doc format.

S20: Send a path query request containing the initial data identifier to the client, so that the client queries whether there is a path recording the initial data identifier from the storage medium of the client according to the path query request, obtains the first query result, and compares the first query result. The query result is sent to the server.

Specifically, the server sends a path query request containing the initial data identifier to the client. The path query request includes a path query instruction for the initial data identifier. After receiving the path query request, the client responds to the initial data identifier. The path query instruction identified by the data, and the first query result is obtained, and then the first query result is fed back to the server.

Wherein, the path query instruction is a computer readable instruction used to query the path of the specified data identifier from the storage medium.

It should be understood that when data is stored, the data is recorded by changing the polarity of the magnetic particles in the storage medium. When reading data, the magnetic head in the client storage device converts the polarity of the magnetic particles on the storage medium to the corresponding The electrical pulse signal is converted into a data format that can be recognized by the computer. At present, when the data file is deleted or modified by the method provided by the operating system, the particle polarity on the magnetic medium will not be cleared, and the operating system is only an index of the data Part of the modification was made. The corresponding paragraph mark of the data to be deleted was marked for deletion. The polarity of the magnetic particle protecting the deletion mark was identified through the initial data mark and path acquisition instructions, and the polarity of the magnetic particle of the deletion mark was judged. Whether there is record data corresponding to the initial data identifier, the first query result is obtained.

Wherein, the first query result includes the storage path corresponding to the record of the initial data identifier is queried and the storage path corresponding to the record of the initial data identifier is not queried.

S30: Receive the first query result fed back by the client.

Specifically, after the client completes the query, the first query result is sent to the server, and the server receives the first query result and makes different response strategies according to the first query result.

As described in step S20, the first query result includes the storage path corresponding to the recorded initial data identifier is queried and the storage path corresponding to the recorded initial data identifier is not queried. When the client has a storage path corresponding to the recorded initial data identifier, it is also That is, the data file corresponding to the initial data identifier can be directly restored from the storage medium of the client; when the client does not have a storage path corresponding to the initial data identifier, that is, the initial data identifier cannot be mapped from the client. Recovery of data files.

S40: If the first query result is that the storage path corresponding to the recorded initial data identifier is not queried, obtain user information corresponding to the client.

Specifically, when the first query result is that the storage path corresponding to the initial data identifier is not queried, that is, when the backup data corresponding to the initial data identifier cannot be obtained on the storage device of the client, the client corresponding The user information of the user information, and then the subsequent data restoration through the cloud data corresponding to the user information.

Among them, the user information is information used to uniquely determine the user of the client, which may specifically be, but is not limited to, the MAC address of the client, the user account password, and real-time verification information.

If the user information is the MAC address of the client, when performing cloud data backup for the first time, the MAC address corresponding to the client needs to be entered, the server stores the MAC address, and allocates dynamic storage space for the client corresponding to the MAC address.

If the user information is the user account password, when the cloud data backup is performed for the first time, the client sends a registration request to the server and performs the registration process. After the registration is successful, the server saves the user account and password, and is the user account password The corresponding client allocates dynamic storage space.

Among them, real-time verification information is only real-time verification of client users, such as mobile phone numbers and verification codes, biometrics, etc.

It should be noted that this embodiment provides a variety of selectable user information methods, so that while ensuring user data security, different client users are provided with more choices, which is conducive to improving user experience. Client users can choose any one. This kind of user information is used for subsequent identity verification, that is, subsequent identity verification can adopt different verification methods according to the different user information selected by the client.

S50: Perform identity verification of the cloud server on the user information, and obtain the identity verification result.

Specifically, by performing cloud identity verification on the user information obtained in step S40, the identity verification result is obtained.

In this embodiment, the cloud server stores the cloud data corresponding to multiple clients. In order to ensure the data security of each client user and save the resources of the cloud server, the cloud storage device provided by the server dynamically provides for each client The user allocates cloud storage space and needs to authenticate the client user before restoring the data through the cloud. After the verification is passed, the client user's corresponding cloud storage space is inquired about whether there is data to be restored.

Among them, the identity verification result includes verification passed and verification failed.

It should be noted that, as described in step S40, this embodiment presets different verification methods for different types of user information. Specifically, the type and verification method of user information can be set according to actual needs, and we will not do more here. limit.

Preferably, this embodiment adopts the real-time verification information and the voice information of the user’s voiceprint information as the user information for verification to ensure the data security of the client user. For the specific implementation process, please refer to the description of step S51 to step S56, in order to avoid Repeat, not repeat it here.

S60: If the identity verification result is passed, the cloud data corresponding to the initial data identifier is obtained from the cloud server in a preset manner as the target data. Among them, the cloud data is a hot update method to update the real-time data of the client Synchronize the data stored in the cloud database.

Specifically, when the identity verification result is that the verification is passed, the cloud data corresponding to the initial data identifier is screened out from the cloud server in a preset manner as the target data.

Among them, hot update is a data synchronization method. In this embodiment, it refers to a method of real-time synchronization of client files to the cloud server in real time, and there is no need to close the file during the synchronization process. For the specific process, please refer to step S81 to step The description of S83 will not be repeated here.

Among them, the preset mode can be set according to actual needs, and there is no restriction here.

Preferably, this embodiment adopts a dynamic decryption method to obtain the cloud data corresponding to the user information from the cloud server. For the specific process, refer to the description of step S61 to step S65. To avoid repetition, details are not repeated here.

S70: Send the target data to the client.

Specifically, the server sends the selected target data to the designated location of the client for storage through the network transmission protocol.

Among them, network transmission protocols include but are not limited to: Internet Control Message Protocol (ICMP), Address Resolution Protocol (ARP Address Resolution Protocol, ARP), File Transfer Protocol (File Transfer Protocol, FTP), etc.

In this embodiment, when the data restoration request sent by the client is received, the initial data identification included in the data restoration request is obtained, and then the path query request containing the initial data identification is sent to the client, so that the client can follow the path Query request, query whether there is a path to record the initial data identifier from the storage medium of the client, and obtain the first query result, receive the first query result fed back by the client, and if the first query result is that the initial data identifier has not been queried and recorded When the corresponding storage path is used, the user information corresponding to the client is obtained, and the user information is authenticated by the cloud server to obtain the identity verification result. If the identity verification result is verified, it will be obtained from the cloud server through a preset method The initial data identifies the corresponding cloud data as the target data. The cloud data is the data stored in the cloud database by synchronizing the client's instant data with the hot update method, and sending the target data to the client. The storage device performs a query. If the data file corresponding to the initial data identifier is not stored in the client storage device, the cloud server further queries the synchronization file corresponding to the initial data identifier in the cloud data synchronized by hot update, and performs the data Restoration provides multiple dimensions of data restoration security, which is conducive to improving data security. At the same time, using hot update to synchronize real-time data to the cloud server is also conducive to real-time and fast data storage and backup to ensure data security Sex.

On the basis of the embodiment corresponding to FIG. 2, the following uses a specific embodiment to verify that if the authentication result in step S60 is passed, the initial data is obtained from the cloud server in a preset manner. Identifies the corresponding cloud data, as a specific realization method of the target data for detailed description.

Please refer to FIG. 3. FIG. 3 shows a specific implementation process of step S60 provided in an embodiment of the present application, which is detailed as follows:

S61: If the identity verification result is that the verification is passed, obtain the target key corresponding to the user information, and use the target key to decrypt the cloud data to obtain the cloud data corresponding to the user information.

Specifically, when the identity verification result is that the verification is passed, the target key corresponding to the user information is obtained, and the cloud data is decrypted using the target key to obtain the cloud data corresponding to the user information.

Among them, the target key is a key used to decrypt the cloud data corresponding to the user information. In this embodiment, when the data of the client is synchronized to the cloud server, the cloud server encrypts the synchronized data according to the user information of the client. , Obtain the target key corresponding to the user information and the encrypted cloud data, and store the encrypted cloud data corresponding to the same user information in the same dynamic space. The cloud data corresponding to the dynamic space can be decrypted by the target key. Obtain the decrypted cloud data corresponding to the user information.

It should be noted that, through the target key, the dynamic space corresponding to the user information is directly obtained and decrypted, and the cloud data corresponding to the user information is obtained, which is beneficial to quickly extract the user information from the user information of many different users stored in the cloud server. The user information of the user corresponding to the target key helps to improve the efficiency of data query.

S62: In the data identifier of the cloud data corresponding to the user information, perform query processing on the initial data identifier to obtain a second query result.

Specifically, after the data identifier of the cloud data corresponding to the user information is obtained, the initial data identifier is used as the query object, and the query is performed in the data identifier of the cloud data corresponding to the user information to obtain the second query result.

S63: If the second query result is that there is at least one initial data identifier among the data identifiers of the cloud backup data corresponding to the user information, the cloud data with the initial data identifier is used as the data to be restored.

Specifically, when the second query result is the data identifier of the cloud backup data corresponding to the user information, when there is at least one initial data identifier, the cloud data with the initial data identifier is used as the data to be restored.

It should be noted that if the second query result is that the initial data identifier does not exist in the data identifier of the cloud backup data corresponding to the user information, the query result will be fed back to the client, and the client will be reminded of the initial data identifier of the query through a prompt message Is it wrong.

S64: Send the data identifier of the data to be restored to the client, so that the user of the client selects at least one data identifier from the data identifier of the data to be restored as the data identifier of the target data.

Specifically, the data identifier of the data to be restored is sent to the client. After receiving the data identifier of the data to be restored through the client, the client user selects one or more data identifiers as the data identifier of the target data according to actual needs. , And feed back to the server through a message.

It should be noted that in this embodiment, storage at different time points can be set according to needs, so that one data identifier may correspond to multiple pieces of data, for example, a data identifier whose initial data identifier is "case status table", after querying , Get three data files with data identification as "case status table", their time points are July 1, July 2, and July 6, respectively.

S65: Receive the selection message fed back by the client, obtain the data identification of the target data from the selection message, and determine the target data from the data to be restored according to the data identification of the target data.

Specifically, when the selection message fed back by the client is received, the data identification of the target data is obtained from the selection message, and the target data is determined from the data to be restored according to the data identification of the target data.

In this embodiment, when the identity verification result is that the verification is passed, the target key corresponding to the user information is obtained, and the target key is used to decrypt the cloud data to obtain the cloud data corresponding to the user information, and then the cloud data corresponding to the user information is obtained in the cloud corresponding to the user information. In the data identification of the data, perform query processing on the initial data identification to obtain the second query result. If the second query result is that there is at least one initial data identification in the data identification of the cloud backup data corresponding to the user information, the initial data will exist The identified cloud data is used as the data to be restored, and the data identification of the data to be restored is sent to the client, so that the user of the client selects at least one data identification from the data identification of the data to be restored as the data identification of the target data, and finally receives The client feedbacks the selection message, and obtains the data identification of the target data from the selection message, and determines the target data from the data to be restored according to the data identification of the target data, and quickly finds the target data that needs to be restored from the numerous data stored in the cloud server , Improve the efficiency of query and determination of target data.

On the basis of the embodiment corresponding to FIG. 2, the specific implementation method of performing the identity verification of the cloud server on the user information mentioned in step S50 and obtaining the identity verification result will be described in detail below through a specific embodiment.

Please refer to FIG. 4, which shows a specific implementation process of step S50 provided in an embodiment of the present application, which is described in detail as follows:

S51: Perform voiceprint extraction on the audio information to obtain target voiceprint information.

Specifically, before selecting the identity verification of the cloud server, the cloud server obtains the unique identification information preset by the client as the user identification, and sends the information containing the random verification code to the client, and the user of the client reads the information and performs Recording, using the recording file as user information for identity verification. After receiving the user information, the server extracts the voiceprint information from the audio information, and determines whether the voiceprint information corresponds to the client pre-selected and stored by the cloud server User voiceprint information.

It should be noted that when the client performs cloud server storage for the first time, it needs to enter unique identification information and voiceprint information for subsequent identity authentication.

Among them, the unique identification information may specifically be the MAC address of the client, or the mobile phone number of the client user bound to the cloud server, etc., which is not specifically limited here.

Among them, the random verification code information can specifically be a short message that is automatically generated and sent using the SMS SDK interface. The random verification code generated using the SMS SDK excuse is real-time and random. For example, a random verification code is generated as "Your This time the verification code is h36ty0, and the verification code is valid for 2 minutes".

Among them, the audio information is extracted by voiceprint, and the detailed process of obtaining the target voiceprint information is as follows: The audio information is extracted by voiceprint, and the detailed process of obtaining the target voiceprint information is as follows:

Perform voiceprint analysis on audio information to obtain initial voiceprint samples;

Perform pre-emphasis processing on the initial voiceprint samples to generate emphasized voiceprint samples with a flat frequency spectrum;

Using framing and windowing methods, perform framing processing on the emphasized voiceprint samples to obtain the initial speech frame;

Perform silent sound separation on the initial speech frame to obtain the target speech frame;

Based on the target speech frame, the voiceprint feature is extracted, and the obtained voiceprint feature is used as the target voiceprint information.

It is easy to understand that the target voiceprint information is the voiceprint information included in the verification information, and the voiceprint information is subsequently verified to determine whether the voiceprint information is the voiceprint information corresponding to the client.

Among them, pre-emphasis is a signal processing method that compensates for the high-frequency components of the input signal at the transmitting end. As the signal rate increases, the signal is greatly damaged during transmission. In order to get a better signal waveform at the receiving terminal, it is necessary to compensate for the damaged signal. The idea of pre-emphasis technology is to enhance at the beginning of the transmission line. The high-frequency component of the signal is used to compensate for the excessive attenuation of the high-frequency component in the transmission process, and the pre-emphasis has no effect on the noise, so the output signal-to-noise ratio is effectively improved.

Among them, framing refers to dividing the entire speech signal into frames, that is, dividing it into many segments. A speech signal is not stable as a whole, but it can be regarded as stable locally, and it needs to be input in the later speech processing. It is a stationary signal, so the entire speech signal needs to be framed, that is, divided into many segments. The signal can be considered stable in the range of 10-30ms, and generally no less than 20ms is a frame.

Among them, windowing is to use a windowing function to process the framed speech signal to make the speech frame continuous. After the frame is processed, there will be discontinuities at the beginning and end of each frame. The more the error from the original signal, the greater the error. Through the windowing process, the framed signal becomes continuous, and each frame will show the characteristics of the periodic function.

It is easy to understand that the target voiceprint information is the voiceprint information contained in the verification information. The voiceprint information is subsequently verified to determine whether the voiceprint information is the preset user voiceprint information of the client pre-stored in the cloud server .

S52: Compare and verify the target voiceprint information with the user voiceprint information of each preset client to obtain a first verification result.

Specifically, in the cloud storage device on the server side, the voiceprint information corresponding to each client terminal that uses audio information verification is pre-stored as the preset permission voiceprint information, and the calculation steps are respectively calculated through the preset similarity calculation method. The similarity between the target voiceprint information obtained in S51 and each preset authority voiceprint information is obtained, and the similarity value between the target voiceprint information and each preset authority voiceprint information is obtained. If these similarity values exist If the similarity value is greater than or equal to the preset similarity threshold, it is determined that the target voiceprint information is one of the preset permission voiceprint information. At this time, the voiceprint verification result is confirmed to be verified. If these similarity values are all If the similarity value is less than the preset similarity threshold, it is determined that the target voiceprint information does not belong to any one of the preset permission voiceprint information. At this time, the voiceprint verification result is confirmed to be a verification failure.

The preset similarity calculation methods include but are not limited to: cosine similarity, k-Nearest Neighbor (kNN) classification algorithm, Manhattan Distance (Manhattan Distance), and Hamming distance based on SimHash algorithm.

S53: Convert the audio information by adopting a voice-to-text method to obtain the target text.

Specifically, the audio information is text-converted through a preset voice-to-text method to obtain the target text.

Among them, the preset voice-to-text method can be implemented through a voice-to-text algorithm, through a third-party tool, or through a third-party application programming interface (Application Programming Interface, API). The selection is based on actual needs and is not limited here.

S54: parse the target text to obtain the current verification code.

Specifically, a preset regular expression is used to perform regular matching on the target text to obtain the current verification code contained in the target text.

S55: Perform legality verification on the current verification code to obtain a second verification result.

Specifically, the legitimacy of the current verification code obtained in step S54 is verified to obtain a second verification result, where the second verification result includes verification passed and verification failed. When the legitimacy verification is passed, it is confirmed that the second verification result is The verification is passed, and when the legality verification fails, it is confirmed that the second verification result is a verification failure.

Among them, the legality verification is used to verify whether the current verification code is consistent with the initial verification code. If the current verification code and the initial verification code are consistent with the initial verification code, it is determined that the current verification code has passed the legality verification; otherwise, the current verification code is confirmed. The legality verification failed.

It should be noted that there is no inevitable sequence of execution between step S51 to step S52 and step S53 to step S55, and it may be executed in parallel, which is not limited here.

S56: If the first verification result and the second verification result are both verified, then confirm that the identity verification result is verified.

Specifically, when the first verification result and the second verification result are both verified, it is confirmed that the identity verification result is verified.

It is easy to understand that if the first verification result is verification failure, or the second verification result is verification failure, or both the first verification result and the second verification result are verification failures, then it is confirmed that the identity verification result is verification failure. The customer feedbacks the prompt message of the verification failure, and records and saves the audio information and verification information to the preset abnormal information file, so that subsequent analysis of the preset abnormal information file can obtain the cause of the abnormality, and Make corresponding exception handling.

In this embodiment, the target voiceprint information is obtained by extracting the voiceprint of the audio information, and then the target voiceprint information is compared and verified with the user voiceprint information of each preset client, and the first verification result is obtained. , Use the voice-to-text method to convert the audio information to obtain the target text, and then parse the target text to obtain the current verification code, and then verify the legality of the current verification code to obtain the second verification result. Finally, in the first When both the first verification result and the second verification result are verified, the identity verification result is confirmed to be verified. An audio file is used to confirm the user's identity in multiple dimensions to quickly and conveniently confirm the legality of the user's identity and improve data security.

In one embodiment, after step S30, if the first query result is that the storage path corresponding to the recorded initial data identifier is queried, the data restoration method further includes restoring data from the client through instructions, specifically as follows:

Specifically, in this embodiment, for a file that runs in real time, the update data file and the user information of the client are obtained from the client through a preset step.

Among them, the update data file refers to the content that has changed since the last update of the implemented file.

Among them, common synchronization methods include, but are not limited to: file copy, file movement, file real-time sharing, etc.

Preferably, in this embodiment, in order to facilitate the file operation, the data of the changed file is directly read from the memory of the client, and the data is updated to the cloud server for storage by hot update. The specific process can be Refer to the description of step S82, or step S821 to step S824, in order to avoid repetition, the details are not repeated here.

It should be noted that the update and acquisition of the client's data file can be done in a timed manner, or in real-time storage, or a combination of the two.

For example, in a specific embodiment, a combination of timed saving and real-time saving is adopted, the timed saving is set to automatically save for 5 minutes, and the real-time saving is real-time saving when a passively triggered save instruction is received.

S82: Synchronize the update data file to the original backup data corresponding to the update data file to obtain the backup data corresponding to the user information, and encrypt the backup data corresponding to the user information to obtain the target key corresponding to the user information and the corresponding user information Cloud data.

Specifically, the update data file is synchronized to the original backup data corresponding to the update data file to obtain the backup data corresponding to the user information, and the backup data corresponding to the user information is encrypted to obtain the target key and user information corresponding to the user information Corresponding cloud data.

The specific methods of encryption processing include, but are not limited to: Message-Digest Algorithm 5 (MD5), RSA (RSA algorithm) encryption algorithm, and key encryption block algorithm (Data Encryption Standard, DES), etc.

It encapsulates the update content into the bundle package, which can directly release and run the update data and resource files contained in the bundle package, but also ensure that the update data and resource files will not be used during use. Access to other users ensures the security of updated data and resource files.

It should be understood that the process of generating the resource file package in this step belongs to the background silent generation and does not affect file reading and writing. Therefore, the file update data can be obtained and backed up without closing the file.

S823: Perform a difference comparison between the updated resource package and the original backup file to obtain difference information.

Specifically, the method of data link list analysis is used to perform a difference comparison between the updated resource package and the original file, and the difference information between the two is obtained.

Among them, the method of data link list analysis refers to using the original backup file to establish a data link list, and the obtained update resource package is inserted in the form of difference comparison with the data in the data link list.

Among them, the data linked list is a non-contiguous, non-sequential storage structure on a physical storage unit, and the logical order of data elements is realized through the link order of the pointers in the linked list. The linked list is composed of a series of nodes (each element in the linked list is called a node), and the nodes can be dynamically generated at runtime. Each node includes two parts: one is the data field that stores the data element, and the other is the pointer field that stores the address of the next node.

S824: Use the difference information to update the original backup file to obtain the updated file, and synchronize the updated file to the cloud backup data as the backup data corresponding to the user information.

Specifically, after the difference information is obtained, the original backup file is updated using the difference information to obtain the updated file, and the updated file is synchronized to the cloud backup data as the backup data corresponding to the user information.

In this embodiment, the original backup file corresponding to the updated data file is obtained from the cloud server, and then the updated content corresponding to the updated data file is obtained, and the resource file package is generated according to the updated content, and then the difference between the updated resource package and the original backup file is performed The difference information is obtained by the difference information, and then the original backup file is updated with the difference information, and the updated file is obtained, and the updated file is synchronized to the cloud backup data as the backup data corresponding to the user information to realize the rapid synchronization of the updated data file To the cloud server, the efficiency of data synchronization is improved, data loss caused by sudden abnormalities is reduced or avoided, and data security is improved.

It should be understood that the size of the sequence number of each step in the foregoing embodiment does not mean the order of execution. The execution sequence of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.
