The invention discloses a
population flow monitoring method. The method comprises the following steps: receiving a binding request; generating a
user identifier according to the binding request, wherein the
user identifier comprises an eID, a type tag and a state tag; establishing and updating an associated network
pool according to the
user identifier; receiving an association request, querying two user identifiers in an association network
pool according to the association request, and establishing an association chain between the two user identifiers; and acquiring update data and updating the state
label marked by the user in the association network
pool according to the update data. According to the ivnention, contact between people is converted into
data point-to-point network chain connection through code scanning, card swiping or face recognition. The method has the beneficial effects that firstly, one point is tracked through a network chain, so that the monitoring response speed is increased; secondly, identity information and place and place records are not included, so that the
data security is improved; 3, the data volume only comprises an association chain and time, so that data volume is small, the monitoring response speed is further improved, and cyclic updating is facilitated.
