In many computing scenarios, individual profiles are generated from facts specified by, observed about, and/or inferred about individuals, and may be used to personalize services to such individual. Such facts may include details provoking a sensitivity of an individual, and it may be undesirable to reveal the collection and use of such facts to the individual; however, such facts may also enable accurately personalized service. These considerations may be balanced by partitioning the individual profile into a foreground profile, comprising facts that are revealed to the individual, and a background profile, comprising facts that are collected about but not revealed to the individual. Services may be covertly personalized for the individual based on the sensitive information stored in the background profile (e.g., restaurant recommendations that are overtly recommended based on the current location of the individual, and also covertly selected based on an inferred income level of the individual).
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method of representing an identity of an individual on a device comprising a processor and an individual profile of the individual, the method comprising: executing, on the processor, instructions that cause the device to: upon receiving a fact about the individual at a detection time: determine a significance of the fact to the identity of the individual; upon determining that the significance of the fact to the identity of the individual exceeds a significance threshold, add the fact to the individual profile; and upon failing to add the fact to the individual profile within an evaluation duration of the detection time, discard the fact about the individual. 2. The method of claim 1, wherein determining the significance of the fact to the identity of the individual further comprises: detecting an expression by the individual of the significance of the fact to the identity of the individual. 3. The method of claim 2, wherein: the individual specifies a fact order of the respective facts of the individual profile, wherein a first fact having an earlier fact order in the individual profile is more significant than a second fact having a later fact order in the individual profile; and wherein determining the significance of the fact to the identity of the individual further comprises: determining the significance of the fact according to the fact order of the individual profile. 4. The method of claim 1, wherein determining the significance of the fact to the identity of the individual further comprises: among an expression set of expressions by the individual, detecting a frequency of references to the fact by the individual. 5. The method of claim 1, wherein determining the significance of the fact to the identity of the individual further comprises: for respective activities by the individual, determine an activity conformity of the activity of the individual with the fact; and determine an activity conformity frequency among the activities of the individual. 6. The method of claim 1, wherein determining the significance of the fact to the identity of the individual further comprises: predicting a sensitivity of the individual to acknowledging the fact; and upon predicting the sensitivity of the individual to acknowledging the fact that exceeds a sensitivity threshold, discarding the fact about the individual. 7. The method of claim 6, wherein predicting the sensitivity of the individual to acknowledging the fact further comprises: determining a demographic trait of the individual; and for an individual set comprising individuals exhibiting the demographic trait, determining a demographic sensitivity of the individuals of the individual set to acknowledging the fact; predicting the sensitivity of the individual according to the demographic sensitivity to acknowledging the fact of the individuals of the individual set that is associated with the demographic trait of the individual. 8. The method of claim 1, wherein: the fact comprises an inference about the individual; and determining the significance of the fact further comprises: determining an inference confidence that the fact describes the individual. 9. The method of claim 8, wherein determining the inference confidence of the inference further comprises: presenting a fact detail about the fact to the individual; and detecting an individual interest of the individual in the fact detail. 10. The method of claim 8, wherein determining the inference confidence about the inference further comprises: presenting an option set comprising the fact and at least one alternative fact; and detecting an individual interest of the individual in the fact that exceeds the individual interest of the individual in the at least one alternative fact. 11. A server that manages an individual profile of an individual, the server comprising: a processor; and a memory storing instructions that, when executed on the processor, provide: a significance evaluator that determines a significance of the fact to the identity of the individual; and an individual profile manager that: upon the significance evaluator determining that the significance of the fact to the identity of the individual exceeds a significance threshold, adds the fact to the individual profile; and upon failing to add the fact to the individual profile within an evaluation duration of the detection time, discards the fact about the individual. 12. The server of claim 11, wherein the individual profile manager adjusts the evaluation duration according to a confidence of the significance of the fact to the identity of the individual. 13. The server of claim 11, wherein the individual profile manager, upon receiving a request from the individual to exclude a selected fact from the individual profile, excludes the selected fact from the individual profile. 14. The server of claim 11, wherein the individual profile manager, upon receiving from the individual a disavowal of a fact, excludes the selected fact from the individual profile. 15. The server of claim 11, wherein: the individual profile further comprises a fact limit; and the individual profile manager, upon determining that the individual profile comprises a fact count that exceeds the fact limit, removes at least one fact from the individual profile. 16. The server of claim 15, wherein removing the at least one fact from the individual profile further comprises: identifying, within the individual profile, a low significance fact having a low significance to the identity of the individual among the facts of the individual profile; and removing the low significance fact from the individual profile. 17. A memory device storing instructions that, when executed by a processor of a device storing an individual profile of an individual, manage the individual profile by: upon receiving a fact about the individual at a detection time: determining a significance of the fact to the identity of the individual; upon determining that the significance of the fact to the identity of the individual exceeds a significance threshold, adding the fact to the individual profile; and upon failing to add the fact to the individual profile within an evaluation duration of the detection time, discarding the fact about the individual. 18. The memory device of claim 17, wherein the instructions further manage the individual profile by: after adding the fact to the individual profile, monitor the significance of the fact to the identity of the individual; and upon detecting that the significance of the fact to the identity of the individual has diminished below the significance threshold, remove the fact from the individual profile of the individual. 19. The memory device of claim 18, wherein monitoring the fact further comprises: upon detecting a conflicting fact about the individual that conflicts with the fact, initiate monitoring the significance of the fact to the identity of the individual. 20. The memory device of claim 17, wherein the instructions further manage the individual profile by, after adding a selected fact to the individual profile and upon detecting a conflicting fact about the individual that conflicts with the selected fact: present to the individual a request to confirm the conflicting fact; and upon receiving confirmation of the conflicting fact, exclude the selected fact from the individual profile of the individual.
