## Abstract

A method executed by a mobile apparatus for verifying event information to be shared is disclosed. The method includes communicating with a nearby mobile or immobile apparatus to generate a verification in response to encountering the nearby mobile or immobile apparatus. The method also includes verifying existence of an incident event in response to arriving at a place of the incident event. The method further includes publishing a verified incident event in order to add into an incident event distributed ledger used for managing event information related to the incident event.

## Claims

### Claim 1

A mobile apparatus for sharing event information, the mobile apparatus comprising:
a memory tangibly storing program instructions; and
a processor in communications with the memory, wherein, by executing the program instructions, the processor is configured to:
select a remote incident event of interest, the remote incident event being associated with a first event management distributed ledger and a first account;
pay a reward for provision of event information about the remote incident event to the first account;
send a first reference request about the remote incident event to a first other mobile apparatus, the first other mobile apparatus being recorded in an existing verified event block of the first event management distributed ledger; and
receive event content relating to the remote incident event from the first other mobile apparatus.

### Claim 2 (depends on 1)

The mobile apparatus of claim 1, wherein the verified event block includes one or more event notifications relating to the remote incident event, each event notification including a place of an event, time of the event and a signature of a respective issuer, the first other mobile apparatus being one of the issuers included in the one or more event notifications in the verified event block.

### Claim 3 (depends on 1)

The mobile apparatus of claim 1, wherein the mobile apparatus is further configured to:
receive an event notification issued by a second other mobile apparatus;
verify the event notification relating to an incident event; and
create a verified event block constituting an event management distributed ledger associated with an account, the account being used for collecting a reward from one or more information subscribers of the mobile apparatus and the first other mobile apparatus;
wherein at least part of the reward collected into the account is distributed to an information verifier in response to clearance of the incident event.

### Claim 4 (depends on 3)

The mobile apparatus of claim 3, wherein verifying the event notification comprises:
inquiring an event content of the event notification from the second other mobile apparatus; and
gathering a group of event notifications having event contents similar to the event content of the event notification.

### Claim 5 (depends on 4)

The mobile apparatus of claim 4, wherein the mobile apparatus is further configured to:
in response to successfully creating the verified event block, publish the verified event block including the event notification and the group of the event notifications; and
in response to unsuccessfully creating the verified event block, receiving the verified event block published by a third other mobile apparatus and validating the verified event block.

### Claim 6 (depends on 4)

The mobile apparatus of claim 4, wherein verifying the event notification further comprises:
analyzing the event contents of the group of event notifications to detect a change of state in the incident event; and
wherein gathering the group of event notifications further comprises:
gathering only ones of the group of event notifications that reflect a most recent state of the incident event.

### Claim 7 (depends on 3)

The mobile apparatus of claim 3, wherein the mobile apparatus is further configured to:
determine whether the incident event has been cleared;
in response to determining that the incident event has been cleared, declare clearance of the incident event in the event management distributed ledger; and
issue a distribution remittance for distributing the reward collected in the account, wherein a remittance block for the distribution remittance is added to a balance management distributed ledger after confirming that the event management distributed ledger includes a declaration of the clearance of the incident event issued by the information verifier.
