Problems solved by technology
The traditional information storage method is generally stored locally on the terminal. For example, the medical platform will use the terminal to store each patient's medical record information, patient information and other information locally on the terminal. This information storage method has a large risk, and illegal terminals are easy Obtaining 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

Embodiment Construction
[0040] 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.
[0041] 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 invention discloses an information processing method, device and equipment for generating random numbers based on attributes of information, and mainly relates to a blockchain technology and a medical platform technology, and the method comprises the steps: obtaining a target function for describing the information, and the attribute information of each piece of sub-information in the target information; generating a root key according to user information contained in the target information, and generating a key corresponding to each piece of sub-information according tothe root key; generating a first random number corresponding to each piece of sub-information according to the attribute information of each piece of sub-information, and adjusting each piece of sub-information according to the first random number to obtain each piece of adjusted sub-information; obtaining coordinate information of each piece of sub-information according to the target function andeach piece of adjusted sub-information; and encrypting the coordinate information of each piece of sub-information by adopting the key corresponding to each piece of sub-information to obtain a ciphertext of the target information, and storing the ciphertext of the target information into the blockchain network. By adopting the embodiment of the invention, the security of the 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 random numbers 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 traditional information storage method is generally stored locally on the terminal. For example, the medical platform will use the terminal to store each patient's medical record information, patient information and other information locally on the terminal. This information storage method has a large risk, and illegal terminals are easy Obtaining 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 .
