DETAILED DESCRIPTION
Following are a series of flowcharts depicting implementations of processes. For ease of understanding, the flowcharts are organized such that the initial flowcharts present implementations via an overall “big picture” viewpoint and thereafter the following flowcharts present alternate implementations and/or expansions of the “big picture” flowcharts as either sub-steps or additional steps building on one or more earlier-presented flowcharts. Those having skill in the art will appreciate that the style of presentation utilized herein (e.g., beginning with a presentation of a flowchart(s) presenting an overall view and thereafter providing additions to and/or further details in subsequent flowcharts) generally allows for a rapid and easy understanding of the various process implementations.
With reference now to FIG. 1, depicted is a method of privacy preservation that includes creating a limited-use electronic mail account (step 100); detecting that a limited-use electronic mail account user has accessed the limited-use electronic mail account (step 102); and disabling further use of the limited-use electronic mail account (step 104). The disabling of step 104 may include, e.g., overwriting the limited-use electronic mail account, and/or encrypting the limited-use electronic mail account, and/or preventing the limited-use electronic mail account from accepting further items of electronic mail. The disabling of step 104 may further include, e.g., sending a receipt to a sender of an item of electronic mail to the limited-use electronic mail account signifying that the limited-use electronic mail account is no longer operational. Step 100 may include, e.g., interaction between a smart card and a computer for the creating the limited-use electronic mail account. Those skilled in the art will recognize that, in addition the smart card, in another implementation other email creation methodologies may be used, and such related art methodologies are not expressly recited here for sake of clarity.
Step 100 may be performed, for example, by the account user 130 when the account user 130 requests creation of a limited-use electronic mail account via the device 136 and performed using the device 134, and/or the device, 136, and/or the device 138 in various combinations and permutations thereof within the ambit of one skilled in the art. In another implementation, step 100 may be performed via device 138 automatically creating the limited-use electronic mail account according to some defined pre-set criteria (e.g., creating a defined number of limited-use electronic mail accounts to be later utilized by assigned users). Step 102 may be performed, for example, using the device 134, and/or the device, 136, and/or the device 138 in various combinations and permutations thereof within the ambit of one skilled in the art, when the account user 130 accesses the limited-use e-mail account via the device 136. Step 104 may be performed using the device 134, and/or the device, 136, and/or the device 138 in various combinations and permutations thereof within the ambit of one skilled in the art, after the account user 130 accesses the limited-use e-mail account via the device 136.
FIG. 2 illustrates another aspect, a method of privacy preservation that includes steps 100 and 104, and, in addition, detecting that the limited-use electronic mail account user has accessed the limited-use electronic mail account, including detecting that the limited-use electronic mail account allows a pre-specified number of accesses before the disabling the further use of the limited-use electronic mail account, e.g., a pre-specified number of one (step 106). Step 106 may be performed, for example, using the device 134, and/or the device, 136, and/or the device 138 in various combinations and permutations thereof within the ambit of one skilled in the art when the account user 130 accesses the limited-use e-mail account via the device 136.
FIG. 3 shows another aspect, a method of privacy preservation that includes step 100, and, in addition, detecting that a limited-use electronic mail account user has accessed the limited-use electronic mail account, including detecting that the limited-use electronic mail account allows a pre-specified number of accesses (e.g., one) before the disabling the further use of the limited-use electronic mail account, and including updating an item of data to reflect a total number of accesses by the limited-use electronic mail account user to the limited-use electronic mail account (step 108); and disabling further use of the limited-use electronic mail account, wherein the disabling includes disabling the further use after a value of the item of data updated to reflect the total number of accesses by the limited-use electronic mail account user to the limited-use electronic mail account equals the pre-specified number of accesses (step 110).
Step 108 may be performed, for example, by using the device 134, and/or the device, 136, and/or the device 138 in various combinations and permutations thereof within the ambit of one skilled in the art, when the account user 130 accesses the limited-use e-mail account via the device 136. Step 110 may be performed, for example, by using the device 134, and/or the device, 136, and/or the device 138 in various combinations and permutations thereof within the ambit of skilled in the art, after the account user 130 accesses the limited-use e-mail account via the device 136.
FIG. 4 depicts another aspect, a method of privacy preservation that includes detecting that a limited-use electronic mail account user has accessed the limited-use electronic mail account, including sending a receipt to a sender of an item of electronic mail to the limited-use electronic mail account signifying that the limited-use electronic mail account user has accessed the sender's item of electronic mail in the limited-use electronic mail account (step 112); and steps 100 and 104. Step 112 may be performed, for example, using the device 134, and/or the device, 136, and/or the device 138 in various combinations and permutations thereof within the ambit of one skilled in the art, when the sender 128, using the device 134, sends an item of electronic mail via the device 138 to the limited-use electronic mail account of the account user 130, and when the account user 130, using the device 136, accesses the limited-use e-mail account and the item of electronic mail, the receipt being sent to the sender 128.
FIG. 5 shows a system 114 that includes a processor 116; a memory 118 operably coupled to the processor 116; circuitry 120 operably coupled to the processor 116 and to the memory 118 for creating a limited-use electronic mail account; circuitry 122 operably coupled to the processor 116 and to the memory 118 for detecting that a limited-use electronic mail account user has accessed the limited-use electronic mail account; and circuitry 124 operably coupled to the processor 116 and to the memory 118 for disabling further use of the limited-use electronic mail account. The circuitry 122 may include circuitry 126 operably coupled to the processor 116 and to the memory 118 for detecting that the limited-use electronic mail account has a pre-specified number of accesses (e.g., one) before the limited-use electronic mail account is to be disabled. The detecting performed by the circuitry 126 may include updating an item of data reflecting the total number of accesses by the limited-use electronic mail account user to the limited-use electronic mail account. The disabling performed by the circuitry 124 may include disabling the further use after a value of the item of data updated to reflect the total number of accesses by the limited-use electronic mail account user to the limited-use electronic mail account equals the pre-specified number of accesses.
FIG. 6 depicts an exemplary environment in which the methods and systems described herein may be represented. The sender 128 is the sender of an item of electronic mail to the limited-use electronic mail account user 130. The sender uses device 134, which may be a wireless handheld device, a laptop computer, a personal computer, a desk computer, a computer system terminal, or any other device capable of providing an interface between the sender 128 and an electronic mail account from which an item of electronic mail may be sent. The mail account user 130 uses a device 136, which may be a wireless handheld device, a laptop computer, a personal computer, a desk computer, a computer system terminal, or any other device capable of providing an interface between the mail account user 130 and an electronic mail account that may receive the item of electronic mail sent by the sender 128. Device 138 is exemplary of any and all intermediate devices that may provide paths and/or computational resources, e.g., one or more electronic mail server and/or transmission media, to carry the item of electronic mail from the sender 128 to the limited-use electronic mail account user 130.
Each of steps 100, 102, 104, 106, 108, 110 and 112 as described above may be performed, e.g., with system 114 as described above. Additionally, each of steps 100, 102, 104, 106, 108, 110, and 112 as described above may be performed using the devices 134, 136, and/or 138 of FIG. 6. For example, step 100 may be performed using the device 134, and/or the device 136, and/or the device 138 in various combinations and permutations thereof within the ambit of one skilled in the art.
One skilled in the art will recognize that the foregoing components (e.g., steps), devices, and objects in FIGS. 1-6 and the discussion accompanying them are used as examples for the sake of conceptual clarity and that various configuration modifications are common. Consequently, as used herein, the specific exemplars set forth in FIGS. 1-6 and the accompanying discussion are intended to be representative of their more general classes. In general, use of any specific exemplar herein is also intended to be representative of its class, and the non-inclusion of such specific components (e.g., steps), devices, and objects herein should not be taken as indicating that limitation is desired.
Those skilled in the art will appreciate that the foregoing specific exemplary processes and/or devices and/or technologies are representative of more general processes and/or devices and/or technologies taught elsewhere herein, such as in the claims filed herewith and/or elsewhere in the present application.
Those having skill in the art will recognize that the state of the art has progressed to the point where there is little distinction left between hardware and software implementations of aspects of systems; the use of hardware or software is generally (but not always, in that in certain contexts the choice between hardware and software can become significant) a design choice representing cost vs. efficiency tradeoffs. Those having skill in the art will appreciate that there are various vehicles by which processes and/or systems and/or other technologies described herein can be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; alternatively, if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware. Hence, there are several possible vehicles by which the processes and/or devices and/or other technologies described herein may be effected, none of which is inherently superior to the other in that any vehicle to be utilized is a choice dependent upon the context in which the vehicle will be deployed and the specific concerns (e.g., speed, flexibility, or predictability) of the implementer, any of which may vary. Those skilled in the art will recognize that optical aspects of implementations will require optically-oriented hardware, software, and or firmware.
The foregoing detailed description has set forth various embodiments of the devices and/or processes via the use of block diagrams, flowcharts, and/or examples. Insofar as such block diagrams, flowcharts, and/or examples contain one or more functions and/or operations, it will be understood by those within the art that each function and/or operation within such block diagrams, flowcharts, or examples can be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or virtually any combination thereof. In one embodiment, several portions of the subject matter described herein may be implemented via Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), digital signal processors (DSPs), or other integrated formats. However, those skilled in the art will recognize that some aspects of the embodiments disclosed herein, in whole or in part, can be equivalently implemented in standard integrated circuits, as one or more computer programs running on one or more computers (e.g., as one or more programs running on one or more computer systems), as one or more programs running on one or more processors (e.g., as one or more programs running on one or more microprocessors), as firmware, or as virtually any combination thereof, and that designing the circuitry and/or writing the code for the software and or firmware would be well within the skill of one of skill in the art in light of this disclosure. In addition, those skilled in the art will appreciate that the mechanisms of the subject matter described herein are capable of being distributed as a program product in a variety of forms, and that an illustrative embodiment of the subject matter described herein applies equally regardless of the particular type of signal bearing media used to actually carry out the distribution. Examples of a signal bearing media include, but are not limited to, the following: recordable type media such as floppy disks, hard disk drives, CD ROMs, digital tape, and computer memory; and transmission type media such as digital and analog communication links using TDM or IP based communication links (e.g., packet links).
In a general sense, those skilled in the art will recognize that the various embodiments described herein can be implemented, individually and/or collectively, by various types of electro-mechanical systems having a wide range of electrical components such as hardware, software, firmware, or virtually any combination thereof; and a wide range of components that may impart mechanical force or motion such as rigid bodies, spring or torsional bodies, hydraulics, and electro-magnetically actuated devices, or virtually any combination thereof.

All of the above U.S. patents, U.S. patent application publications, U.S. patent applications, foreign patents, foreign patent applications and non-patent publications referred to in this specification and/or listed in any Application Data Sheet, are incorporated herein by reference, in their entireties.
The herein described aspects depict different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable”, to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components.
While particular aspects of the present subject matter described herein have been shown and described, it will be apparent to those skilled in the art that, based upon the teachings herein, changes and modifications may be made without departing from this subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of this subject matter described herein. Furthermore, it is to be understood that the invention is solely defined by the appended claims. It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.).
Other embodiments are within the following claims.
