Information processing method and device based on characteristics of information, equipment and medium

Abstract

The embodiment of the invention discloses an information processing method and device based on information features, equipment and a medium, and mainly relates to a block chain technology and a hospital management technology, and the method comprises the steps: obtaining a target function for describing information and feature information of target information; dividing the target information according to the feature information of the target information to obtain at least two pieces of sub-information; obtaining a random number corresponding to each piece of sub-information, and adjusting each piece of sub-information according to the random number to obtain each piece of adjusted sub-information; according to the target function and each piece of adjusted sub-information, obtaining coordinate information corresponding to each piece of sub-information in the at least two pieces of sub-information; encrypting the coordinate information corresponding to each piece of sub-information inthe at least two pieces of sub-information to obtain a cipher text of the coordinate information corresponding to each piece of sub-information; and determining the cipher text as the cipher text of the target information, and storing the cipher text of the target information in the block chain network. By adopting the embodiment of the invention, the information security can be improved.

Description

technical field [0001] This application relates to the technical field of blockchain, and in particular to methods, devices, equipment and media for information processing based on information characteristics. Background technique [0002] With the development of the network, the way of information interaction through the network is favored by a large number of users. The increase in the number of users using the network leads to an increase in the amount of information generated, and a large amount of information needs to be stored, for example, prescriptions for patients in hospital management Transfer, patient management and other information are stored to facilitate subsequent traceability. The traditional information storage method is generally terminal local storage. This kind of information storage method has great risks. Illegal terminals can easily obtain locally stored information, resulting in information leakage, and illegal users can tamper with locally stored i...

The traditional information storage method is generally terminal local storage. This kind of information storage method has great risks. Illegal terminals can easily obtain locally stored information, resulting in information leakage, and illegal users can tamper with locally stored information. Lead to low information security, and, when the local storage fails, the information cannot be retrieved, resulting in loss
