Pets healthcare data would be stored in scattered manner due to the changes in the pet owner, service agency or other reasons, which result in a large number of repeated examinations in healthcare service process and even medical negligence. Therefore, we proposed a blockchain-based pet healthcare data sharing approach so that the pet's healthcare history information can be presented in a complete manner when needed and prevent data from being attacked intensively, moreover, data integrity and accountability in healthcare service processes can be fulfilled. The ciphertext-policy attribute-based encryption(CP-ABE) is used to safeguard the privacy of the pet owner and the confidentiality of the healthcare data of the pets stored in different healthcare service parties. The smart contract is applied to ensure the data interaction between users and the normal acquisition of data after the change of the pet owner. In addition, we provide security analysis and performance evaluation.
