Infomorph, also known a mind uploading, is a term used to describe an entity that is comprised entirely of information; a completely morphed subject whose identity and physical self is no longer grounded in the physical space. The term originated from science fiction, but is not often used. Technically, those who participate on social networks and contribute information to the web are partial infomorphs. Those who are deceased but leave behind a historical set of writing or documents could be considered infomorphs as well. One's informorphic footprint can be larger or smaller based on the amount of material they've created during their lifetime, and the amount of that material that is distributed to the general public. The precise origin of the term infomorph is unknown, but it is suggested that it was first coined by Greg Bear in his book Eon where it was part of a simple three-part classification of posthuman forms.
