1. A distributed type traffic line tracing system comprising:
a traffic line tracing apparatus;
a traffic line tracing management application installed in a mobile phone of a tracing target person, configured to control the mobile phone to:
store a mobile phone location information of the tracing target person provided from a plurality of location information providers in a resident memory of the mobile phone; and
wirelessly transmit the mobile phone location information to the traffic line tracing apparatus;

wherein the traffic line tracing apparatus comprises:
a digital communication module installed in a residence of the tracing target person;
a communication connection verifier, configured to verify whether the digital communication module and the mobile phone are connected through short-range communication;
a tracing target person traffic line information memory configured to store traffic line history information of the mobile phone;
a memory scheduler configured to transfer the mobile phone location information stored in the resident memory to the tracing target person traffic line information memory through wireless connection between the digital communication module and the mobile phone;
a confirmed person traffic line information memory configured to store traffic line information of infected persons provided from the disease management authority terminal through the digital communication module;
a traffic line coincidence determiner configured to determine whether there is an overlapping path between the tracing target person and the infected persons;
a processor configured to:
select the tracing target person as a self-quarantining target person when there is an overlapping path between the tracing target person and the infected persons; and
drive the digital communication module to transmit information related to the selected self-quarantining target person to a disease management authority terminal;

a control right transferer configured to transfer a control right of the processor to the disease management authority terminal; and
a residence departure detector configured to report suspected residence departure to the disease management authority terminal when the self-quarantining target person left the residence for a predetermined time or more,
wherein the residence departure detector includes
a virtual phone bell generator configured to generate a virtual phone bell sound when it is suspected that the self-quarantining target person left the residence, and
wherein, when the self-quarantining target person does not answer the virtual phone bell sound even though the virtual phone bell sound is output a predetermined number of times or more, the residence departure detector is further configured to determine that the self-quarantining target person has left the residence, and report self-quarantining target person departure to the disease management authority terminal.
