According to the method, redundant information of data medical treatment is deleted, health data is classified by using data attributes and access forms, and an encryption task is completed by using a chaos cell neural network and a wavelet transform method, so that the safety of the health data is ensured, the time complexity of encryption operation is reduced, the encryption efficiency is improved, and the risk of network congestion is reduced.
