In order to make the objects, technical solutions and advantages of the present application more clear and clear, the present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
As shown in fig. 1, the user data protection method according to the preferred embodiment of the present application includes the following steps:
and S10, collecting user data, identifying and evaluating the user data by adopting preset standards and rules, and classifying and managing the user data according to importance and confidentiality levels.
Specifically, the user data is collected and classified, including personal information, behavior records, equipment information, service associated data and the like, and the user data classification is a process of classifying and managing the user data according to different importance and confidentiality levels.
In hierarchical management of user data, certain criteria and rules are typically employed to identify, evaluate and classify user data, such as evaluating and ranking confidentiality, integrity, availability, etc. of data, to formulate different security policies and control measures to protect the data.
The application classifies the collected user data, including personal information, history record, preference setting and the like, and stores the user data in different data tables, wherein different types of data are stored in different data tables, and different levels of encryption modes are different. The classification mode can better protect the privacy of the user and prevent the abuse of the user data.
And step S20, identifying the private data and the sensitive data in the user data according to the data type, carrying out encryption storage and data backup on the private data and the sensitive data, and setting a deleted recovery function.
Specifically, by the definition of national standards on user data, identifying which are private data or sensitive data, judging according to data types, such as mobile phone numbers, identity card numbers and bank cards, wherein the private data or the sensitive data are all sensitive data; the user privacy data and the sensitive data are stored in an encrypted manner, for example, a database is built by a cloud server for storage, the sensitive data of the user can be stored in an encrypted manner, meanwhile, the user attribute and the secret key are stored in different databases, and the security is higher; for example, the user's data is ranked into three categories:
(1) Internal public data, not encrypted;
(2) Secret data, performing AES encryption;
(3) Confidential data is subjected to AES+RSA encryption.
Simultaneously carrying out data backup on the private data and the sensitive data to prevent important data from being lost; in addition, a deleted recovery function is set, recovery is the reverse operation of user logout, and is an active operation initiated by the user, if the user logout the account, the account will enter a cold static period, for example, the cold static period is 60 days, after the recovery, the original data is unchanged, if the user does not recover, after the cold static period is over, the data is deleted, and the previous data cannot be recovered.
The application adopts the distributed storage (the distributed storage refers to the storage mode of dispersing and storing data on a plurality of computers or servers so as to improve the storage capacity, the data reliability and the expandability, has the advantages of expanding, high reliability, high performance and the like), encryption storage and other technologies, and ensures the safety of user data. In addition, a data backup and recovery mechanism is realized, and the integrity and usability of the user data are ensured.
And step S30, setting user permission for accessing the private data and the sensitive data based on a role-based access control model, wherein the authorized user has the permission for accessing the private data and the sensitive data.
Specifically, access control is performed on the user data, and only authorized users can access the user data. User authorization and internal authorization: the system can acquire related data after the user authorization; after the security evaluation and the auditing are carried out inside, the data authorized by the user can be used after the authorization is carried out.
The present application employs a role-based access control model (RBAC, which uses roles as an allocation unit of permissions to control user access to system resources according to the roles and responsibilities of the users, each user is allocated to one or more roles, and each role has a specific set of permissions. The access control strategy can better protect user data and prevent illegal access.
And step S40, the logged-off user data and invalid user data are deleted periodically.
Specifically, the logged-off user data and invalid user data (for example, if the account numbers are combined, that is, one account number becomes invalid, for example, if a WeChat is first registered as a platform account number and a mobile phone number is then registered as a platform account number, two account numbers are formed, after the WeChat is logged in, the mobile phone number is unbound, and one of the account numbers is combined into an invalid account number) are deleted periodically, so that the storage space occupied by the useless data is avoided and the privacy safety of the user data is ensured.
The application periodically cleans invalid data, realizes a data backup and recovery mechanism, and ensures the integrity and availability of user data. The regular cleaning strategy can better protect user data and prevent useless data from occupying storage space.
And S50, recording a log of access, modification and deletion operations of the user data, and carrying out security monitoring on the user data according to the log.
Specifically, logs of access, modification, deletion and other operations of the user data are recorded, so that an administrator can audit and monitor the user data, the audit and the monitoring are mainly performed on the use of the user data, illegal use and excessive use of the user data are prevented, and the use of the user data is minimized.
The application records the logs of the operations such as accessing, modifying and deleting the user data, realizes the centralized management and audit of the logs, and can better ensure the traceability and the safety of the data.
