Abstract

The invention provides a close contact person tracking method, a device, a storage medium and electronic equipment. The method comprises the steps: storing a close contact record data table comprisingan encryption identification code of a first user and an encryption identification code corresponding to a close contact person in a blockchain node in advance, and carrying out the intelligent contract technology when the state of a user changes; and executing decryption of the encryption identification code, obtaining the encryption identification code of the close contact person on the block chain, extracting the public key and the private key of the close contact person according to the key number of the close contact person, decrypting the encryption identification code corresponding tothe close contact person to obtain personal information of the close contact person, and sending notification information to the corresponding close contact person. The tracking of a close contact person is realized. In the tracking process of the close contact person, encryption protection is provided for personal information of the user, and the tracking function of the close contact person is achieved on the premise that personal privacy information (behavior data or position data and the like) of the user does not need to be provided.
