Summary:The invention discloses a data protection method and system based on a block chain, and belongs to the technical field of data processing. The method comprises the following steps: creating a plurality of channels by using a multi-channel mechanism; in each channel, data information and encryption information of to-be-encrypted data are obtained, the to-be-encrypted data are encrypted by using a random key and a symmetric encryption algorithm to obtain encrypted data, and the encryption information is generated by the authority center end through a multi-authority attribute-based encryption algorithm; uploading the encrypted data to obtain an accessible address of the encrypted data; based on the data information, the encryption information, the random key and the accessible address, performing encryption by using a multi-authority attribute-based encryption algorithm to obtain a ciphertext; the method comprises the following steps of: uploading ciphertext and data information through an intelligent contract
