Social Networking tools for NGO Security – Part 1

I was experimenting with Twitter when it occurred to me that it was an ideal tool for NGO security officers. Rather than using the service to merely update friends on what I was having for breakfast I could be sending out security information alerts and updates. All my “followers” would then get current, low cost, security information.

This method has many advantages over the SMS security tree method commonly used by NGOs. Traditional security trees tend to fail when one or more members (the branches of the tree) do not receive or pass on the text messages they receive to those below them, typically because they are on leave or because the tree information is not up to date. Traditional trees can also be expensive. Each SMS sent by every member of the tree comes out of someone’s budget. This can add up quickly if you are sending out several messages a day to a two hundred-member security tree.

Social networking services like Twitter or Jaiku allow us to avoid these problems. Essentially Twitter and Jaiku allow the head of the security tree to send one SMS to the service’s server. The service then distributes the SMS to all the “followers” (subscribers) of the account more or less simultaneously. This means the tree still works even if members are missing. In addition you only pay for the SMS to the service’s server. SMS messages from the server to each of the followers are free*.


* Most mobile service providers only charge for text messages that are sent while those received are free.
