Abstract: In order to solve the problems of low data security, access control accuracy and long data query time existing in traditional data access control methods, this paper proposes a secure storage data access control of smart TV based on blockchain. Firstly, the naive Bayesian algorithm is used to calculate the posterior probability according to the data safety level. Secondly, the category corresponding to the maximum posterior probability is regarded as the category of the data, and the data classification is realised by iterative calculation. Finally, on the basis of data classification, different categories of smart TV secure storage data access control are realised through ciphertext encryption, data decryption, access policy update and other steps based on blockchain. Experimental results show that the method has high data security, the average accuracy of data access control is 96.3%, and the data query time is always less than 0.5 s.
