During a sudden crisis scenario, earthquake, flood or something similar, one of the major problems facing a lot of people is the lack of information about the people in the area. People don't know where where their friends and members of the family are. Event if they are ok, sharing this information with everyone interested is difficult since the phone lines and networks may be broken or at least in heavy use. Also the rescue workers trying to help people want to know who is in the area and how they are doing. This information can help them coordinate their work better.

For this problem we propose a shared information system for collecting the information about the people in the crisis area which can be updated ad new information arrives. The information can be updeted by the people themselves, by rescue workers and by th community users who have information about a person in the area.

The goals of our solution:

• Gathering the information about the people in crisis area in one location
• Providing easy way of accessing this information to everyone interested - Officials, people working in the area, people with friends or relatives at the area
• Providing easy way of updating the information about missing people
• Identifying the people found but not identified - children, injured or deceased people

Mainly our system offers a common way of communicating and sharing information between all the people involved in crisis scenario.

• Officials input list of residets of the area
• Hotels etc input list of their customers
• Community users input the names of the people they know to be in the area, but who are not yet listed
• People start adding information about people who are found
• Rescue workers add pictures of unidentified people
• Community users identify people in pictures
• All the time the statistics of crisis scenario are updated

• The service - A database with data and (WCF) web service interface
• Web client - Client for viewing statistics, searching people and adding updates
• Mobile client - Field client for adding pictures of unidentified people and other updates
• (Excel client - A client for adding list of people?)

All the basic functionalities of the system will be implemented in the server and they are accessible through WCF web service interfaces. The main user interface will be the web user interface implemented with Silverlight. The user interface relies on Bing map to show the locations of the crisis and the people in the area. This user interface can be used by all users, by the officials in charge, by the people working in field of the crisis area and by community users - people outside the crisis location who are interested in the crisis or who have some information about people in the area.

Mobile client is meant for people working in crisis area helping people. Using the mobile client they can update information about people tehy encounter or they can take pictures of unidentified people and upload them to the server so the community users may identify them.

The excel client is a simple client meant just for adding information about a list of people. It can be used by officials who have the information about the residents of the area or for example hotel staff who can add the information about their clients.
