To improve the security of data access,this article introduces blockchain technology and conducts research on cloud storage data security access control methods.This method uses modulation technology to set control variables,calculate the expected benefit of the data access channel,balance the design of the cloud storage data access channel,and uses the E elliptic curve encryption algorithm in blockchain technology to generate a pair of public and private keys,and generate access permission ciphertext.The main content included in designing smart contracts is to provide secure access control for cloud storage data.The comparative experimental results demonstrate that the article design method can achieve accurate identification of abnormal data.
