Close contact person tracking method, device, storage medium and electronic equipment

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.

Description

technical field [0001] The present application relates to the field of information processing technology, and in particular to a method, device, storage medium and electronic equipment for tracing close contacts. Background technique [0002] Close contact tracking can help users self-judge their contact history with risk personnel (infectious virus carriers, potential hazards to public safety, etc.), and it has strong technical support for personnel management and control in emergencies, reducing risk personnel Unnecessary harm to ordinary people (isolation of personnel, financial loss from business closures). Therefore, close contact tracing is becoming more and more important in modern social management, bringing convenience to daily life. [0003] In order to use information technology to solve the problem of close contact tracking, at present, for the tracking of close contacts in the new coronary pneumonia, a variety of "dynamic and active" epidemic prevention schemes...

Problems solved by technology

[0004] Although thanks to the popularization of Bluetooth low energy technology, almost all smart terminal devices equipped with low energy Bluetooth can realize the tracking of close contacts, but in the process of tracking close contacts, at least the user's movement trajectory data needs to be When users' personal information is uploaded to a third-party system, a certain amount of user privacy needs to be sacrificed, so that the user's personal privacy cannot be guaranteed
