Task Based Information Flow Control

Technology allows society to be very connected and available. Methods for communication include telephone, voicemail, email, instant messaging, cell phone, pager, 2-way radio, intercom, etc. There may even be several of these devices in use at a single time by a single user.

There are two problems that all these different forms of communication present. The first problem is that humans can only carry on a limited number of "conversations" at a time. For instance, it is very hard to talk on a phone and a cell phone at the same time. The second problem is that sometimes people are busy and do not want to be contacted, or at least only want certain people to be able to contact them.

The core idea of this paper is to have an application for a personal computer, or similar device, recognize the situation a person is in and adjust all the communication devices that person has accordingly. Situations would be recognized by input from the communication devices, and by monitoring usage of applications running on the computer. Situations could also be set manually by the user. The adjustment to the communication devices would be based on a set of predefined rules that could be customized.

The lowest level is device control. For the purposes of this paper device control is only for incoming communication. For phones incoming calls may be turned on or off. If caller id is available incoming phone calls may be enabled or disabled for individuals or categories/groups of individuals. For instance a person could have a device setting that disables all phone calls except his/her spouse, secretary, and project lead. If there are multiple device settings active for a device the most exclusive combination is the one that will be used.

Portable devices may be controlled through industry standard connections such as bluetooth, infra-red, 802.11b, cable connections like USB or firewire, email, web, or other interfaces. Device control protocols will use industry practice protocols including device specific device drivers or standards based protocols such as xml. Device discovery will use industry practice discovery methods such as zeroconf, plug and p...
