Problems solved by technology
The existing information storage method is generally terminal local storage. For example, the medical platform will use the terminal to store each patient's medical record information, patient information and other information. This kind of information storage method has a large risk, and illegal terminals are easy to obtain to the information stored locally, leading to information leakage, and illegal users can tamper with the information stored locally, resulting in low information security, and, when the local storage fails, the information cannot be retrieved, resulting in losses

Embodiment Construction
[0039] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0040] The blockchain involved in this application is a new application mode of computer technologies such as distributed data storage, point-to-point transmission (P2P transmission), consensus mechanism, encryption algorithm, etc. Data blocks associated with cryptographic methods, each of which contains a batch of network transaction information, is used to verify the validity of the information (anti-counterfeiting) and generate the next block. The blockchain can include the underlying platform...

The embodiment of the present application discloses an information processing method, device, and equipment for generating a key based on the attribute of information, mainly related to blockchain technology and medical platform technology, wherein the method includes: obtaining an objective function for describing information and a to-be-processed The attribute information of each sub-information in the target information; the key of each sub-information is generated according to the attribute information of each sub-information; the first random number corresponding to each sub-information is obtained, and each sub-information is adjusted according to the first random number to obtain the adjustment each piece of sub-information after adjustment; obtain the coordinate information corresponding to each piece of sub-information according to the objective function and each piece of sub-information after adjustment; use the key of each sub-information to encrypt the coordinate information of each piece of sub-information to obtain the ciphertext of the coordinate information ; Determine the ciphertext of the coordinate information corresponding to each sub-information as the ciphertext of the target information, and store the ciphertext of the target information in the block chain network. By adopting the embodiment of the present application, the security of information can be improved.
Description
technical field [0001] The present application relates to the technical field of blockchain, and in particular to an information processing method, device and equipment for generating keys based on information attributes. Background technique [0002] In this era of rapid network development, more and more information is interacted and stored through the network. The existing information storage method is generally terminal local storage. For example, the medical platform will use the terminal to store each patient's medical record information, patient information and other information. This kind of information storage method has a large risk, and illegal terminals are easy to obtain Locally stored information leads to information leakage, and illegal users can tamper with locally stored information, resulting in low information security, and when the local storage fails, the information cannot be retrieved, resulting in losses. Therefore, how to ensure the security of info...
