Problems solved by technology

[0003] In the prior art, encryption methods such as the Advanced Encryption Standard (AES) are usually used to encrypt user information. The Advanced Encryption Standard needs to undergo operations such as round key encryption, byte replacement, row displacement, and column mixing. The volume is large, the operation is complicated, and the encryption algorithm is very common. Encrypting user information according to this encryption algorithm has the risk of being cracked, and financial user information has security risks

Embodiment

[0057] The embodiment of the present invention provides a method for encrypting medical insurance financial user information based on big data, such as figure 1 As shown, the method includes:

[0058] S101: Obtain user information, store the user information in a queue, and obtain a user information queue.

[0059] S102: Obtain a first user information block from the user information queue, where the length of the first user information block is one third of the length of the user information queue, and the first user information block includes a plurality of user information.

[0060] S103: Obtain the first key in the key queue.

[0061] S104: Encrypt the first user information block based on the first key to obtain a first ciphertext.

[0062] S105: Obtain a second user information block from the user information queue, the length of the second user information block is two-thirds of the length of the user information queue, and the second user information block is identic...

Abstract

The embodiment of the invention provides a medical insurance financial user information encryption method and system based on big data. According to the method, the first number of characters in the first character string are sequentially stored in the queue, and then the second number of characters in the second character string are stored in the queue, so that the user name and the user passwordcan be restored from the user information queue more easily. According to the method, the characters in the first character string are randomly stored in the queue, so that the encryption of the userinformation is improved, the target ciphertext is not easy to crack, and the security of the user information is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and system for encrypting medical insurance financial user information based on big data. Background technique [0002] With the progress of the human age, people pay more and more attention to human health, but medical expenses are also very expensive, so medical insurance is becoming more and more popular and promoted for this reason. In the past, people went through the relevant procedures of medical insurance by purchasing from the staff of the insurance institution, signing the contract, and going through the reimbursement procedures. This method required a lot of manpower. At the same time, the services of the insurance institution could not reach remote areas. area. With the development of science and technology, online medical insurance related procedures have been popularized. For example, people can purchase medical insurance and go through medical i...
