receiving, by the cloud server, event occurrence information from a second smart device;

determining, by the cloud server, a type of an event, an event occurrence time, and an event occurrence point as the event occurrence information;

determining, by the cloud server, a group member associated with the event occurrence time and the event occurrence point among the group members of the registered access group as an event group member;

determining, by the cloud server, required information depending on the type of event and requesting the required information corresponding to the event occurrence time to the event group member; and

acquiring and storing, by the cloud server, the required information from the event group member.

2. The method of claim 1 , wherein:

the wireless access device is an access point of a local area communication network or a base station of a mobile communication network.

3. The method of claim 1 , wherein:

in the determining of the event group member,

a group member of a group to which the first smart device providing the event occurrence information at the event occurrence time belongs is determined as the event group member.

4. The method of claim 1 , wherein:

in the determining of the event group member,

a smart device positioned within a set radius based on the event occurrence point at the event occurrence time is determined as the event group member.

5. The method of claim 1 , wherein:

in the determining of the event group member,

group members of respective access groups corresponding to all wireless access devices having a part of a set radius based on the event occurrence point at the event occurrence time as an access area are determined as the event group members.

6. The method of claim 3 , wherein:

when information on an escape direction of an assailant is included in the event occurrence information,

determining the event group member and acquiring the required information from the event group member, and thereafter,

determining the group member of the access group positioned in the escape direction as the event group member and requesting and acquiring the required information.
