A number of people in a population send regular pre-formatted status messages through any available communication tools. These messages state that nothing is wrong; they are "Happy Life Signal" (HLS). If the population is under attack, they will just stop sending their status. A receiving centralized system server will detect the massive break, and conclude an attack is on-going. The attackers will lead to the same result if they try to cut the communication system. And they may have a hard time to massively force the population to send HLS during a raid.
The system may also be used by wealthy countries, so that it may become the basis for a buzz and an entertaining app; this may benefit the needing communities.
Definitions of the terms
Supported Communication Tools are made of combinations of any available devices, available communication technologies, dedicated client applications, and/or dedicated servers, as described here below.
Any (or as many as possible)
available type of devices should be supported: computer, mobile, fixed phone, radio.The devices may be personal devices, community devices (e.g. a village's phone or shop's computer), or devices that have been distributed to the population for this purpose in identified sensitive situations and areas (meaning to an endangered population, having a poor communication system, or an unevenly distributed access to the communication tools).
In correlation with the supported devices,
any available type of technology should be supported: internet, mobile, landline, satellite.
dedicated client applications are deployed on supporting devices, like smartphones or computers. The role of the app is to provide with the pre-formatted status message, an identifier of the user and of the device location. Since the device may be used by several people, the app lets the user enter an identifier; on such login, it sends the positive status message, with its location.
dedicated servers are made so to correspond to the various device/technology/client applications. In the case of a smartphone for instance, the server is an usual app server. In case of the landline, an automatized call-center may gather the status messages.
The dedicated server applications forward the received status (or a summary thereof) to a centralized system server. This
HLS system server is in charge of detecting the situation where it does no more receive a predefined threshold number of regular status for an area. An area may be defined by the system maintenance, in order for instance to reflect the cutting into sensitive regions. Or it can be just an emerging pattern.
The set up
If there are individuals with supported devices, it should be tried by all means to get them involved. They may send HLS on a personal basis, to tell they are OK; or they can act for small communities, like families, small villages, public places.
If not personal, the shared devices can be at specific (but many) places where people inevitably spend some time during a normal day, that is the "happy life places": public places, baths, marketplaces, wells, food stores, offices, etc. As many as possible pre-registeered users can use the device with an identifier.
Instead of trying to send alert messages in case of danger and attacks, people send happy messages. As an incentive, the pre-formatted status messages can be selected among a pre-defined list of options. Pre-formatted messages can also include some degree of happiness, for the people to express for instance that they start feeling endangered. This may be used by the system server to re-enforce an alarm.
This also participates to a "positive point of view on life", by letting people tell they are happy rather than the opposite.
Registering new users must be easy since there is no specific threat in signaling happiness.
