Abstract
The invention discloses a data safety storage method based on privacy protection. The method comprises the steps that a mapping mechanism of user privacy information and a data file is adopted to achieve the isolated storage of the data file and the user information, an authentication module and a data preprocessing module are designed at a storage end, an erasure code technology based on an RS is adopted to process the data file, data are decomposed into a plurality of data blocks which are stored in different storage nodes respectively in a multiple-copy mode, and the safe and reliable storage of the data is guaranteed. According to the data safety storage method, the reliability and the privacy of the data in the storage process are improved.
Description
Technical field
The invention belongs to data security technical field of memory, particularly in cloud storage system to privacy of user data memory protection method.
Background technology
Along with infotech develop rapidly, the generation information technology such as cloud computing, Internet of Things, mobile Internet have changed working method and the life style of people, wherein, cloud computing and internet, mobile Internet etc. bring the explosive growth of data and the continuous various application occurred, accelerate the arriving of large data age, also changing the custom of storage of subscriber data, increasing user starts data to store beyond the clouds.Stored by cloud, user can obtain cloud computing resources anywhere or anytime and not be subject to the restriction of region, time and resource, and cloud stores the progress greatly facilitating digital Age.
The fast development of cloud storage market brings more facility to the work of user and life, but the storage security of user to oneself private data also exists doubt simultaneously, and secret file and divulging a secret of data can bring immeasurable impact to user.Therefore, propose a kind of secure storage method of data based on data-privacy protection to have great importance.
At present, the security method menu that data for user are stored in high in the clouds is many, but be mostly the principle stored based on data encryption, loss or the password of whole file data are cracked, directly results in the leakage of whole information, the safe storage how strengthening user privacy information and data file is necessary.
In sum, this method have employed carries out isolated storage method to user privacy information and data file, and adopts mapping mechanism to ensure the degree of association of user and data, improves the security that user carries out data storage.
Summary of the invention
A kind of secure storage method of data based on data-privacy protection that the embodiment of the present invention provides, in order to solve security and user privacy information that user privacy information and data file store and the risk problem that data file is revealed.
By the isolated storage by user privacy information and data file, realize user and data file carries out mapping mechanism one by one, authentication module and data preprocessing module is devised at storage end, adopt, based on RS correcting and eleting codes technology, piecemeal process is carried out to data file, adopt the mode of many copies to leave in different memory nodes respectively, ensure the safe and reliable storage of data.
A kind of secure storage method of data based on data-privacy protection that the embodiment of the present invention provides; by the isolated storage of user privacy information and general data file; set up the relevance between mapping mechanism guarantee user and file; the risk that user privacy information and data file are leaked simultaneously can be effectively reduced, improve the security in data storage procedure.
Accompanying drawing explanation
The method flow diagram that Fig. 1 provides for the embodiment of the present invention;
What Fig. 2 provided for the embodiment of the present invention carries out file block processing flow chart based on RS correcting and eleting codes technology;
Embodiment
For safety issue in existing user privacy information and data file storing process, the embodiment of the present invention utilizes distributed principle in cloud storage environment, for the different memory requirements of different pieces of information, realize effective isolation and the mapping of user privacy information and data file, adopt RS correcting and eleting codes technology carry out coded treatment and be stored in different memory nodes in the mode of many copies.
As shown in Figure 1, the secure storage method of data based on data-privacy protection that the embodiment of the present invention provides comprises the following steps:
Step 101, initiate data file storage resource request by user;
Step 102, storage end authentication module authentication of users relevant information, if certification is passed through, be for further processing, otherwise re-start checking;
First step 103, storage end data pretreatment module process the data submitted to user, the information such as time stamp T that concrete extraction user ID, file ID, file hash value and file store, preserves user, map record one by one between file ID and data file three;
Step 104, the private datas such as user profile will be related to be stored into privacy of user database;
Step 105, employing RS correcting and eleting codes technology carry out piecemeal process to data file;
Step 106, the data processed are stored in File Pool in the mode of many copies;
As shown in Figure 2, the RS correcting and eleting codes technology that the embodiment of the present invention provides is carried out coding to file and is comprised the following steps:
The segmentation of step 201, data file and filling.Be divided into m+1 equal and opposite in direction to subscriber data file and be the data segment of n multiple, insufficient section is supplementary with 0;
Step 202, data packet coding.RS erasure code is carried out to each grouping, obtains data block D
iwith check block C
j;
Step 203, integrated data are synthesized.Integrated data after coding is synthesized, is stored in different file fragmentation M
k(k=1,2 ..., i+j) in, wherein file fragmentation is all made up of the data block of file different piece and check block;
Step 204, file fragmentation copy storage.Slicing files in step 203 is stored in different memory nodes in the mode of many copies.
As can be seen from above-described embodiment: the embodiment of the present invention is for the basic condition in privacy of user data and general data file storing process; propose the secure storage method of data based on private data guard; the method can effectively reduce the risk that user privacy information and data file are leaked simultaneously, improves the safety and reliability in data storage procedure.
Obviously, those skilled in the art can carry out various change and modification to the present invention and not depart from the spirit and scope of the present invention.Like this, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
