All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1 is a method for processing information provided in an embodiment of the application, which may include the following steps:
s101, receiving an information viewing request for a first user to view user information of a second user.
The information viewing request carries the identity of the first user and the identity of the second user, and the identity of the user can be the unique user number of the user.
The user information of any user is encrypted in advance and stored in a first block, the first block stores the user information of all users belonging to the same authority level in advance, the first block is a block in a preset blockchain, the authority level of the user is allocated to the user in advance, and the authority levels of different users can be different, so in this embodiment, the blockchain can comprise a plurality of different first blocks. The user information of any user is encrypted by adopting a public key randomly extracted from a preset public key pool.
S102, sending query requests whether to agree the first user to view the user information of the second user to all preset advanced authority users.
The advanced authority user is a pre-designated user, and the inquiry request also carries the identity of the first user and the identity of the second user.
The implementation manner of the step can comprise the steps of A1 to A3:
and A1, respectively acquiring key information of the first user and the second user from a preset second block according to the unique user numbers of the first user and the second user.
The second block is a block in a preset block chain, the second block comprises key information of all users, and any one key information comprises a unique user number of the user, a public key identifier of a public key corresponding to the user information of the user, a private key corresponding to the public key and a permission level of the user.
Because the key information of each user includes the unique user number of the user, the key information of the second block user can be acquired according to the unique user number of the user.
And A2, determining the authority level of the first user from the key information of the first user, and determining the authority level of the second user from the key information of the second user.
And A3, under the condition that the authority level of the first user is determined to be greater than that of the second user, sending an inquiry request about whether the first user agrees to view the user information of the second user or not to all preset advanced authority users.
In this embodiment, optionally, the permission level of the first user is greater than that of the second user, which is a precondition that the first user can view the user information of the second user.
S103, receiving a feedback result of each advanced authority user for the inquiry request.
And the feedback result aiming at the inquiry request is that the first user is agreed to view the user information of the second user, or the first user is not agreed to view the user information of the second user.
And S104, acquiring the user information of the second user under the condition that the feedback result is that the number of the advanced authority users agreeing to the first user to view the user information of the second user is larger than a first threshold value.
In this embodiment, the first blocks store user information of all users belonging to the same authority level in advance, so user information of users of different authority levels is stored in different first blocks. The different first blocks can be distinguished according to the authority levels of the users corresponding to the user information in the first blocks, that is, the first blocks have a one-to-one correspondence with the authority levels of the users. Further, the user information for each user included in the first block has a unique user code for that user.

Since any one of the key information includes a unique user number of the user, a public key identification of a public key corresponding to the user information of the user, a private key corresponding to the public key, and a authority level of the user, the public key identification of the public key can be determined from the key information of the second user.
And step B2, obtaining a public key corresponding to the public key identification from a preset public key pool.
In this embodiment, the public key pool stores a plurality of public keys in advance, and each public key has a corresponding public key identifier. All data information included in the public key pool is stored in a third block, wherein the third block is a block in the preset block chain.
And B3, decrypting the user information of the second user by combining the public key and the private key corresponding to the public key.

S202, sending permission level modification requests to all preset advanced permission users.
S203, receiving a feedback result of each advanced authority user aiming at the authority level modification request.
The feedback result of the permission level modification request is that the first user is granted to modify the permission level, or the first user is not granted to modify the permission level.
S204, under the condition that the feedback result is that the number of the advanced authority users agreeing to the first user to modify the authority level is larger than a second threshold, key information of the first user is obtained from the second block.
As described in the foregoing embodiment, the second block includes key information of all users, and any one key information includes a unique user number of the user, a public key identifier of a public key corresponding to the user information of the user, a private key corresponding to the public key, and a permission level of the user. Therefore, the key information of the first user in the second block can be acquired based on the unique user number of the first user.
S205, determining a first block where the user information of the first user is located according to the authority level of the user included in the key information of the first user, and extracting the user information of the first user from the first block.
As described in the foregoing embodiments, the first blocks are in one-to-one correspondence with the authority levels of the users, so that the first blocks where the first user information is located can be determined according to the authority levels of the users.
S206, modifying the authority level in the key information of the first user into a target authority level.
S207, transferring the user information of the first user to a first block corresponding to the target authority level.

Furthermore, even if the first user does not send the permission level modification request, but directly modifies the permission level from the key information of the first user in the second block, because the key information of the user is stored in the third block in the preset blockchain, the first user is difficult to tamper with the key information.
The above embodiment, optionally, further includes: the execution log of the information processing method of the above embodiment is stored in the fourth block, that is, the execution log of each step in fig. 2 is recorded and stored, so that the stored data can be analyzed at a later stage.
