The present application relates to the technical field of block chain, and particularly relates to a kind of identity authentication encryption method based on block chain node user, comprising the following steps: step 1: build user identity information database, obtain user identity information data in database storage;Step 2: traversing reading the user identity information data stored in database, extract character data in the user identity information data stored in database, and apply character data to build the encryption database used when user is authenticated on block chain node;The method in the present application further constructs the key database with the identity information of the user on the basis of the encryption algorithm used when the existing block chain node user is authenticated in the process of executing its steps, so that the further encryption of the key database constructed is applied when the block chain node user is authenticated, so that the block chain node user is more secure when being authenticated.

The application discloses a data encryption method and device. The method comprises the following steps: obtaining a first target time, a target place and to-be-encrypted data in input parameter data; selecting an arbitrary time before the first target time as an offset time from a historical time period; generating first offset information based on the offset time and the target place; obtaining an environmental information array of the target place in the offset time, and combining a plurality of target environmental variables selected from the environmental information array to generate a key; and encrypting the to-be-encrypted data based on the first offset information and the key. The application solves the technical problem of data leakage caused by the fact that the prior art cannot provide more reliable encryption for data.

The invention discloses a big data artificial intelligence data encryption method, and relates to the technical field of big data artificial intelligence data encryption, and the method comprises the steps: collecting to-be-encrypted data through a database, and carrying out the preprocessing of the to-be-encrypted data; performing security level classification on the to-be-encrypted data through artificial intelligence; performing encryption strength calculation according to the data security level division to generate an encryption key; performing encryption operation by using artificial intelligence; storing the encrypted data; and recording an audit log. According to the method, security level classification is performed on the data through the sensitivity of the data, the encryption key with the corresponding strength is generated according to the security level division of the data, and the data is encrypted by adopting an artificial intelligence encryption technology, so that the aims of higher-level and safer encryption of the high-sensitivity data are fulfilled, and the method has the advantages of improving the efficiency of encryption operation, reducing the cost and the like. And the encryption strategy can be flexibly adjusted according to the characteristics of the data and the environment change, so that the data security is greatly improved.
