fig. 2 is a schematic hardware structure diagram of a user privacy data storage device in a social application according to a preferred embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is described in further detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for storing user privacy data in a social application according to a preferred embodiment of the present invention. As shown in fig. 1, it includes the steps of:
s100, when the fact that a user uses the social application is detected, social data generated when the user uses the social application are obtained;
s200, obtaining user privacy data in the social data, and storing the user privacy data after carrying out hash processing on the user privacy data to a user client and a client of a friend in the social application of the user;
step 300, obtaining a hash value corresponding to the user privacy data and non-privacy data in the social data, and uploading the hash value and the non-privacy data to a server for storage.
In specific implementation, the user privacy data in the embodiment of the present invention includes, but is not limited to, data of personal information such as a user's real name, a phone number, an email, a job, an address, and the like.
When the user uses the social application to chat, a large amount of data can be generated, when the later inquiry is facilitated and the user uses the social application, the user privacy data is obtained, the user privacy data is stored in terminal equipment associated with the user in a distributed storage mode through encryption, and if in the social application, the data is stored in clients of all friends of the user and other login equipment of the user.
The method comprises the steps of carrying out Hash (Hash) processing on private data of a user, such as data of personal information, such as real names, telephone numbers, electronic mailboxes, jobs and addresses, in a client, uploading generated Hash values to a server, and uploading non-private data generated when a social application is used to the server. Since the hash algorithm is irreversible, the hash value corresponding to the private data of the user cannot be restored to a plaintext in the server, which is equivalent to that the server does not store the private data of the user. By adopting distributed storage, the personal information of the user is stored in the associated terminal equipment, so that the method is safer and is not easy to lose compared with a centralized storage mode. The user information is encrypted through an encryption algorithm and then stored in the terminal, and even if data is leaked, the user does not need to worry about the information being stolen. The server does not store the user data, and privacy problems do not exist.
The client sends the hash of the necessary user data for supporting the service (such as searching, matching and the like) to the server for storage, and the client stores a copy for associating with the original information. Therefore, the server side can not reveal privacy data of the user, the service function is completed at the same time, and the service function of the application can be ensured to be normally operated while zero privacy of the server is realized.
In a further embodiment, when detecting that the user uses the social application, before obtaining the social data generated when using the social application, the method includes:
and a friend list of a social relation bound with the user in the social application is obtained in advance.
In specific implementation, when the user uses the social application, a friend list of the social relationship bound with the user in the social application is obtained in advance. If the friend list of the user has the opposite party but the friend list of the opposite party does not have the current user, the friend does not have the social relationship with the user.
Further, obtaining user privacy data in the social data, and storing the user privacy data after performing hash processing on the user privacy data to the user client and the client of the friend in the social application of the user, includes:
the method comprises the steps of obtaining user privacy data in social data, conducting hash processing on the user privacy data to generate a hash value, obtaining an encrypted private key, and sending the private key and the hash value to a user client and a client of a friend in social application of a user through HTTPS;
and the user client and the client of a friend in the social application of the user encrypt the user privacy data according to the private key to generate a ciphertext, and the ciphertext and the hash value are stored in a local database.
In specific implementation, the encryption mode of the client side is as follows: and distributing the private key to the terminal through the HTTPS, and then encrypting and storing the data to a local database through the private key by the terminal. Even if someone takes the data of the local database of the terminal, the data is secure since there is no corresponding public key to decrypt. The ciphertext is obtained by encrypting the user privacy data original text.
Further, obtaining user privacy data in the social data, and storing the user privacy data after performing hash processing on the user privacy data to the user client and the client of the friend in the social application of the user, includes:
obtaining user privacy data in the social data, and judging whether the user privacy data is text data or photo data;
if the user privacy data are character data, after the hash processing is carried out on the user privacy data, a ciphertext and a hash value corresponding to the user privacy data are stored to the user client and the client of all friends in the social application of the user;
and if the user privacy data is photo data, after the hash processing is carried out on the user privacy data, storing the ciphertext and the hash value corresponding to the user privacy data to the user client and the client of the friend meeting the preset conditions in the social application of the user.
In specific implementation, the predetermined condition is that the online time exceeds a predetermined time or the contact frequency with the user exceeds a predetermined frequency threshold. The preferred predetermined time period may be set to 5 hours and the predetermined frequency threshold may be set to 1 time/day. Or set as desired.
The private data of the user is defined as data of personal information class, such as name, telephone, work, address and the like, and data of identity document class and bank card class. The information of the text class occupies the storage space of the device, and can be ignored after being compressed, and the photo data of the certificate class is not stored in the client of all friends, but 50-100 friends who are often online or frequently contacted are selected, for example, if 1 user stores 20 photos of the certificate class (the number of the certificate itself is relatively limited) and is compressed to 1 million per photo (the compression is to a size that does not affect the viewing), then 50-100 friend users will occupy the device memory space between 1G and 2G, and the number is still acceptable for the mainstream mobile phone device (the body memory 64G) in the current market.
Further, after obtaining the hash value corresponding to the user privacy data and the non-privacy data in the social data and uploading the hash value and the non-privacy data to the server for storage, the method further includes:
when a user privacy data search instruction of a user client is detected, searching a hash value corresponding to the user privacy data in a server;
and if the hash value corresponding to the user privacy data is matched in the server, acquiring the client which is stored with the hash value and informs that the hash value is stored, and transmitting the requested user privacy data to the user client which initiates the search instruction.
In specific implementation, the client performs Hash (Hash) processing on private data of the user, such as personal information data of real names, telephone numbers, electronic mailboxes, jobs, addresses and the like, to generate a corresponding Hash value, and the client only uploads the Hash value to the server for storage.
Further, in some business functions requiring user privacy data, for example, in the context of human context search, when a user whose position is "XXX" is searched, the user inputs search content at the client, the server performs comparison search on the hash value of the search content in the database to obtain a search result (i.e., a matched hash value), and then notifies the clients storing search result ciphertext data, transmits the data to the client of the user initiating the search, and the user can obtain a plaintext search result after decryption by the client.
Further, obtaining user privacy data in the social data, performing hash processing on the user privacy data, and storing the hash processing result to the user client and the clients of the friends in the social application of the user, includes:
and when the update of the user privacy data is detected, performing data synchronization on the current online user client and the clients of friends in the social application of the user.
In specific implementation, the private data of the user is stored in the client device of the user and the clients of all friends, when the private data of the user is updated, the data of the user is synchronized with other current online devices and the clients of friends, and when the data of some devices is not the latest data, the data of some devices is also synchronized with other online devices containing the latest data.
The method for storing the user privacy data in the social application is implemented, and the storage point of the user personal information is in the device of the user and the devices of friends. The method is normally used at ordinary times, the data stored in the device can be directly accessed, and if the data is installed after being unloaded, the recovered data can be synchronized to the new device by other devices only by logging in other devices of the device or waiting for the devices with friends to be online. If all friends are not online, a user can wait for the friends to be online, and can also send a message notification to some friends through software application to enable the friends to log in the application; or contacting friends and friends of acquaintances in reality to be online; these aids to recover data are not difficult to implement in social applications.
