Referring to fig. 1, the flowchart of a specific embodiment of a mobile phone terminal data backup method based on the hong Monte system in the present application mainly includes the following steps:
in step S101, the mobile terminal user selects all the data to be backed up for the first time to perform full backup and generate a data set, where the data set includes a data privacy tag of the mobile terminal user, and in specific implementation, the data set may be generated by the following manner:
firstly, determining data which need to be backed up and are selected by a mobile phone terminal user, including but not limited to photos, videos, music, documents and the like;
secondly, carrying out full backup on the data to be backed up selected by the mobile phone terminal, namely, completely copying one copy of the data, and uploading the data to a hong Mongolian server for backup, wherein each backup data can be marked with a data privacy label, and the privacy grade degree of the data is marked;
and storing the backup data and the data privacy label into a data set, and establishing an index, so that backup and retrieval are facilitated.
It should be noted that, the types of data to be backed up selected by the user mainly include contacts, information, recorders, applications and data, memos, wi-Fi, cell phone households, scene intelligence, clocks, weather, desktops, harassment interception, etc., while the data privacy label represents the importance of the user to the data, the higher the data privacy grade of the data privacy label is set than the data privacy grade of the data privacy label which is not set, the more important the data privacy label is, the less tolerant to be lost, and the privacy grade is set by the data privacy label, so that the data with the highest priority privacy grade can be backed up, the flexibility of incremental backup of the user data is increased, and details are omitted.
In step S102, the operation event of the mobile terminal user is monitored, and when the operation event of the mobile terminal user on the data set is monitored, the operation event of the data set is recorded in an operation log, and the following manner is adopted when the operation log is specifically implemented:
monitoring an operation event of a mobile phone terminal user on a data set and modifying operation on a data privacy label;
when the operation event of the mobile phone terminal user on the data set is monitored, index information and a data privacy label of the operated data are searched in the data set, and the index information, the data privacy label, the data content abstract, the timestamp of the current moment and the user ID of the data are recorded in an operation log.
It should be noted that, in the present application, the operation of the mobile phone terminal user on the data set may include operations of creating, modifying, and deleting the data set, which is not limited herein specifically.
In step S103, each time a backup time period passes, a data privacy label of the mobile phone terminal user is obtained, and the current backup recommendation degree is determined according to the data privacy label of the mobile phone terminal user and the operation log, and the following implementation method is adopted, namely:

wherein ,for the number of data pieces to be recommended for backup, +.>For the number of all data in the dataset, +.>Is the data in the dataset with the highest data privacy label rating.
In the prior art, in order to backup mobile phone data, a preset backup period is generally set, that is, the time interval of the backup period is fixed. However, this approach may result in different data sizes for each backup. If the granularity of the backup time is set to be too small, a large amount of data fragments can be generated, a large amount of bandwidth and transmission time are occupied, and the normal use of the mobile phone can be influenced; if the granularity of the backup time is set too large, the computing capacity of the mobile phone terminal is limited, and when a large amount of data is processed at one time, the backup delay is serious, and meanwhile, the backup files are larger, so that the storage and transmission are not facilitated. Therefore, a balance needs to be achieved between the backup period and the data size to achieve the optimal backup effect, and the operation log is used in the present applicationAverage data privacy label rating of item +.>Said->Item data to dataset havingDistance of data of highest data privacy label level +.>And the distance of the data with the highest data privacy label level to the first piece of data +.>The method has the advantages that the current backup recommendation degree is determined, the data backup set can be generated by combining the past historical backup data information and the current equipment incremental backup data information, the data size when past data transmission is successfully referenced by the historical backup data experience is fully considered in the determination of the current backup recommendation degree, the backup period can be calculated in a self-adaptive mode, the problems of data fragments and overlong transmission time caused by too small or too large time granularity are avoided, and therefore the backup efficiency and the data transmission success rate are improved.
In addition, the determination of the current backup recommendation degree fully considers the private data grade and the distance between the private data in the current backup data, and can control the length of the data sheet uploaded each time to be uniform while ensuring the priority uploading of important data.
In step S104, the determined current backup recommendation is input to a content backup calculator, which generates a data backup set according to the current backup recommendation, and in specific implementation, the content backup calculator may generate the data backup set according to the current backup recommendation in a plurality of ways, for example, by constructing a decision tree model, using the backup recommendation as an input variable, selecting backup data according to the value of the variable, thereby generating the data backup set, or by clustering backup data, classifying similar data into a group, and then determining which groups of data need to be backed up according to the backup recommendation, thereby generating the data backup set.
In some embodiments, the following description is providedIf the current backup recommendation degree reaches the historical backup recommendation degree measurement value, the operation log information contained in the registration data of the highest data privacy label in the current operation log from the first data behind the preamble backup node can be intercepted; then forming a pre-backup data set according to data corresponding to the record of the creation, modification and deletion operation of the data set in the operation log; finally, searching the data content abstract in the preliminary data set, deleting the repeated data content, obtaining a data backup set, and updating the historical backup recommendation degree measurement value; wherein historical backup recommendation metricsCan be determined according to the following formula:
wherein ,is->And the secondary historical backup recommendation degree measurement value, wherein n is the historical backup times.
In the above embodiment, in order to avoid the interference of the data backup recommendation caused by the extreme situation, such as long-time no data privacy label or all high data privacy label information, the historical backup recommendation measurement is adopted, and because the backup recommendation in the initialization is credible, the method can avoid the influence of the extreme situation, and generate the corresponding data backup set by calculating the reasonable backup recommendation.
In step S105, the backup data is collected according to the data backup set, encrypted and uploaded to the trusted data center, and in specific implementation, the method may be implemented as follows:
firstly, data information is collected according to data indexes in a data backup set to generate a data plaintext, a file access interface of a mobile phone terminal can be accessed according to the index information in the data backup set, backup data are connected end to end according to the sequence in the data backup set, and then the data are fragmented again according to the requirement of an encryption algorithm; collecting data information according to the data indexes in the data backup set processed by the steps to obtain a data plaintext;
secondly, determining a general secret key, and calculating a time secret key by taking a time stamp as a parameter for the highest data privacy label grade data in the current operation log, wherein the time stamp can be used as a private key because the time for writing the operation of a user to the data set into the log is arbitrary and unknown;
and encrypting the data plaintext through the universal key and the time key to obtain a ciphertext, namely combining the universal key and the time key to obtain a subkey, replacing the subkey to obtain a replacement key, and encrypting the data plaintext through the replacement key to obtain the ciphertext.
In the encryption process, the mobile phone terminal can upload the encrypted data sheet to the trusted data center, namely, encrypt the data sheet and upload the encrypted data sheet.
It should be noted that, considering that the computing power of the mobile phone is limited, in some embodiments, a symmetric encryption algorithm is adopted, and according to the algorithm characteristics, the data slice may be set to 64 bits, which is not limited herein.
In step S106, the trusted data center re-encrypts the collected backup data and then uploads the encrypted backup data to the hong Meng Yun backup server for backup, which may be specifically implemented by the following ways:
the trusted data center firstly receives all ciphertext uploaded by equipment in a private network through the private network, then re-encrypts the ciphertext, and particularly generates a re-encrypted public key and a private key during re-encryption, wherein the re-encrypted public key is used for encrypting data, the re-encrypted private key is used for decrypting the data, the ciphertext uploaded by a mobile phone terminal is decrypted to obtain plaintext backup data, and the plaintext backup data is re-encrypted, which is not repeated here.
It should be noted that, as a preferred embodiment, the trusted data center in the present application may further include, after re-encrypting the collected backup data: and the trusted data center performs data fusion on the re-encrypted data to obtain a fusion data set, namely, performs feature reconstruction on the re-encrypted data, and finally fuses the data through features and uploads the data to the hong Meng Yun server for backup.
In some embodiments, data fusion may be achieved in the following manner:
sequentially storing the re-encrypted data in a re-encryption array which is definedA plurality of bit arrays, the bits in each array being initialized to 0;
calculating the data in the re-encrypted data one by one through modulo arithmetic (MOD) to obtain a function value, and recording the function value in a defined bit array;
taking the result expressed by the bit array as a new feature vector, and inputting the new feature vector into a feature reconstruction mechanism;
the feature reconstruction mechanism compresses the new data feature vector and fuses the data according to the result to obtain a fused data set.
It should be noted that in the prior art, the backup data is simply and symmetrically encrypted only at the mobile phone terminal, such as encryption by an advanced encryption standard (Advanced Encryption Standard, AES) algorithm, etc., the encryption mode is relatively simple, if the backup data is intercepted in the process of uploading a key, encryption invalidation will be caused, and unexpected serious consequences are caused.
In addition, the method and the device for processing the data in the private network have the advantages that the trusted data center is introduced to fuse, re-encrypt and block transmission of the backup data in the private network, so that the data processing pressure of the mobile phone terminal is released, when the re-encrypted data are fused, the data are subjected to characteristic reconstruction, the data are fused, system resources can be fully utilized, the occupation of the data on the storage resources of the cloud is reduced, and due to the fact that the data characteristics are extracted, the associated data are stored in the same area more easily, and the data collection efficiency of the system can be improved when the data are restored.
When the mobile phone terminal user sends a data backup and restore request, the hong Meng Yun backup server restores the mobile phone backup data of the mobile phone terminal user according to the data backup and restore request, specifically, the hong Meng Yun backup server can establish a link with the trusted data center, receive and store the fusion data set uploaded by the trusted data center through the data transmission channel, and when the mobile phone terminal user sends a data backup and restore request, restore the mobile phone backup data of the mobile phone terminal user according to the data backup and restore request.
