1. A mobile device configurable for data protection readiness, comprising: a computing system that includes a power system having an on-board energy source, and a processor operatively coupled with a data storage arrangement and a network interface, the computing system further including: a preparation module configured to perform preprocessing to prepare the mobile device for data protection readiness, the preprocessing to be performed autonomously prior to an occurrence of a situation for which the items of data of personal importance are to be secured, and including: computationally determining, from among data stored in the data storage arrangement, certain items of data which are of personal importance to an owner of the mobile device based on a rule set that evaluates an extent of use on the mobile device, by the owner, of applications associated with those data items, wherein different ones of those certain items of data are associated with corresponding different levels of importance; indicating criteria that defines the situation for which the items of data of personal importance are to be secured; and indicating a set of actions to be autonomously carried out to secure the items of data of personal importance, wherein the set of actions includes different protective actions associated with corresponding different levels of importance of the data items; and a protection module configured to autonomously monitor for an occurrence of the situation for which the items of data of personal importance are to be secured based on the criteria indicated by the preparation module, and to execute the set of actions indicated by the preparation module in response to a detection of the occurrence of the situation.
