Description:
BACKGROUND OF THE INVENTION 
   1. Technical Field 
   The present invention relates to organization and security of data, and more particularly, but not by way of limitation, to organization and security of data of a mobile device based on geographic zones and/or personnel secure zones. 
   2. History of the Related Art 
   Mobile devices are currently growing into devices that may handle many types of media. For example, most mobile devices (e.g., mobile telephones, PDAs, laptops, etc.) today are capable of capturing and storing still images or video clips, storing contact information for numerous people, recording voice memos or written memos, etc. With vast quantities of information available for storage by a mobile device, it may become difficult to quickly navigate through menus and listings to find information requested by a user. Currently, mobile devices may store information, such as contacts, according to the individual. For example, a mobile device may have a listing of names and, associated with each name, a home telephone number, a mobile telephone number, email address, etc. 
   As users of mobile devices are now storing large amounts of information, some of which may be work sensitive or personal in nature, mobile device manufacturers are also looking to ways of securing the stored information to prevent information from being accessed or transmitted to others without the user&#39;s permission. Today&#39;s technology allows mobile device users to lock the mobile device to prevent others from viewing information stored therein. However, when the mobile device is locked, according to the current state of the art, none of the information may be accessed on the mobile device and no outgoing calls may be made. 
   In addition, mobile devices may also include Global Positioning System (GPS) for locating the position of the mobile device. Currently, GPS positioning may be utilized by emergency personnel to locate a mobile device when, for example, a 911 call is made from the mobile device. GPS positioning may also be utilized to track the location of the mobile device and/or generate directional instructions to a user of the mobile device.

   DETAILED DESCRIPTION OF THE INVENTION 
   Embodiments of the present invention relate to information sorting and data security based on geographic location and/or personnel. For example, information may be sorted according to geographic location so that when a mobile device is in a specific location, specific data is available for viewing, transmission, etc. Embodiments of the present invention also relate to security features based on secure zones that may be organized by geographic location and/or personnel groups. The geographic secure zones allow specific data to be accessed when the mobile device is in a specific location and the personnel secure zones allow specific data to be accessed when a specific set or subset of personnel are gathered together. The personnel secure zones may be defined by a set of mobile devices of the personnel being within a geographic secure zone as sensed by the mobile device. In another option, the personnel secure zones may be defined by sensing the other mobile devices in an area by e.g., infrared or BLUETOOTH. The personnel secure zones may also be linked to a specific geographic location and/or time period. 
   Referring now to  FIG. 1 , a geographic secure zone in accordance with an embodiment of the present invention is illustrated. A variety of zones may be present in one or more geographic locations. For example, a home zone (zone  1 ), a relative zone (zone  2 ), and a work zone (zone  3 ) may be, for example, within one city or in a geographically dispersed arrangement (e.g., one or more zones located in different cities and/or countries). In addition, zones may be created that overlap other zones and/or may incorporate one or more geographic features, such as a user&#39;s home and work. For example, zone  4  includes both zone  1  and zone  3 . In some embodiments, zones  1  and  3  may be eliminated and only zone  4  may exist. It will be understood by one skilled in the art that more or fewer zones in a wide variety of orientations is possible in accordance with principles of the present invention. 
   Referring now to  FIG. 2 , a mobile device  200  in accordance with an embodiment of the present invention is illustrated. The mobile device  200  includes a microprocessor (MPU)  202  for controlling operation of the mobile device  200 , a display  204  for displaying information to a user, and an optional battery  206 . For geographic secure zones, as noted above with  FIG. 1 , the mobile device  200  includes a geographic sensor  208 , such as, for example, a GPS sensor. For other embodiments, such as those for personnel secure zones, the geographic sensor  208  may not be necessary. The mobile device  200  also includes a memory  210  for storing a plurality of data items. For example, the memory  210  may hold data items related to contacts  212   a ,  212   b , video/still images  214   a ,  214   b , memo data items  216 , and other data items  218   a ,  218   b . The data items may be divided into a home category  220   a  and a work category  220   b ; however, other arrangements are possible. For example, the data items may be separate without the need for home and work categories  220   a ,  220   b . In another option, the contacts  212   a ,  212   b  may be joined into one contacts item without a delineation as to work contacts and home contacts. 
   Referring now to  FIGS. 1 and 2  in combination, the data items may each be associated with a particular zone or zones, or each category (e.g., home or work categories  220   a ,  220   b ) may be associated with a particular zone or zones. For example, data items in the home category  220   a  may only be accessible within zone  1 , zone  4 , zones  1  and  2 , within zones  2  and  4 , etc. Similarly, data items of the work category  220   b  may be accessible within zone  3 , zone  4 , etc. In another option, specific data items may be accessed within specific zones regardless of in which category  220   a  or  220   b  the data item resides. For example, the work contacts  212   b  may be accessible in all zones or zone  4  due to the fact that many users may desire to work from home. However, work sensitive memos, or all data within the memo data items  216 , that require a higher security may be accessible only in zone  3  or only zone  4  in order to prevent viewing or transmission of sensitive work materials to persons other than the user of the mobile device  200 . 
   Referring now to  FIG. 3 , a method  300  of operating a mobile device in accordance with an embodiment of the present invention is illustrated. The method  300  begins at  302  and senses a geographic location at step  304 . At step  306 , data items are associated with at least one zone. Steps  304  and  306  may be performed sequentially, or simultaneously and are interchangeable in order. As noted above, the data items may be associated with a particular zone directly, or each data item may be stored in a category that is associated with a particular zone or zones. At step  308 , it is determined whether the mobile device is within a zone associated with a data item to which the user requests access. If the mobile device is within the associated zone, then access is granted at step  310  and the method ends at step  312 . If the mobile device is not within the associated zone, then access is denied at step  314 . The mobile device then determines either to continue or desist in sensing the location of the mobile device at step  316 . If the sensing is to be discontinued, then the method ends at step  312 . If the mobile device determines that sensing of the location should be continued, then the method continues at step  308 . 
   Referring now to  FIG. 4 , a personnel secure zone is illustrated. In the personnel secure zone, mobile devices identify any other mobile devices located within a predefined area defined by a radius r. As shown in  FIG. 4 , a mobile device D registers that mobile devices B, C, E, F, and G are within the predefined area. A mobile device A and a mobile device H are outside the predefined area. A personnel secure zone may be utilized between a specific group of personnel so that a secure item shared, modified, etc. between the personnel group may not be accessed, modified, shared, etc. without a predetermined number or percentage of the personnel group being present or assenting to the access, sharing or modification. For example, a personnel group of the mobile devices A, B, C, and D may create a secure item, such as a contract, memo, document, etc. The mobile device D may wish to share or modify the secure item. For example, in order for the mobile device D to modify the secure item, a predetermined percentage, such as 75%, of the personnel group must be present. Because the mobile device D senses that 75% of the personnel group (i.e., the mobile devices B, C, and D) is present, the mobile device D may access and/or modify the secure item. In a similar manner, the mobile device D may wish to share the secure item with another mobile device outside of the personnel group, such as the mobile device F. Because 75% of the personnel group is present, the secure item may be shared with the mobile device F. Although the above example is illustrated utilizing the predetermined percentage of 75%, it will be understood by one skilled in the art that other percentages or forms of approval may be utilized for allowing access, etc. to the secure item. For example, a mobile device wishing to modify the secure item may get an approval signal from various ones of the mobile devices of the personnel group. In another option, the personnel group may assign their own parameters for allowing access to the secure item. 
   Referring now to  FIG. 5 , a mobile device  400  in accordance with another embodiment of the present invention is illustrated. The mobile device  400  includes a microprocessor (MPU)  202 , a display  204 , and optional battery  206  in a manner similar to the mobile device  200  of  FIG. 2 . In the embodiment illustrated in  FIG. 5 , the mobile device  400  also includes a device sensor  402  for detecting other mobile devices  400  within a predefined area and a memory  410 . The device sensor  402  may be implemented as, for example, an infrared sensor, BLUETOOTH sensor, or other sensor capable of determining if other mobile devices are present in a predefined area. 
   The geographic sensor  208 , as described above with reference to  FIG. 2 , is optional in the mobile device  400 . If the geographic sensor  208  is not present in the mobile device  400 , the data items may be accessed according to the personnel secure zones. If the geographic sensor  208  is present in the mobile device  400 , then the data items may be accessed according to the personnel secure zones, the geographic secure zones, or a combination of both geographic and personnel secure zones. For example, the, work contacts  212   b  may be accessed based on geographic secure zones and memos or other data items may be accessed according to the personnel secure zones. In addition, secure items that are work related may only be accessed in a geographic work zone (e.g., the zone  3 ) while a predetermined number of the personnel group is present in the personnel secure zone, although other arrangements of geographic secure zones and personnel secure zones may be utilized in accordance with embodiments of the present invention. 
   The memory  410  may be organized into categories  220  similar to that of  FIG. 2 , according to data item (as shown in  FIG. 5 ), or according to other properties as desired. When utilizing personnel secure zones, the memory  410  may include a personnel group data category  406 . The personnel group data category  406  may include identities  408  of mobile devices within the personnel group and rules  412  for allowing access to secure items  414 . Secure items  414  are data items that are accessible according to the personnel secure zones. 
   As illustrated above, data items or secure items may be accessed only when specific conditions are met (e.g., the mobile device  200 ,  400  is within a specific geographic zone or a number of mobile devices  200 ,  400  of the personnel group are present). The inability to access information when these conditions are not met may be provided by various techniques. For example, the secure items or data items may be “locked” to prevent access to a memory location storing the item. In another option, the items may be encrypted and decryption enabled only when the conditions are met to allow access to the items. Other techniques may also be utilized to prevent access to data in accordance with principles of the present invention. 
   Embodiments of the present invention may be utilized to organize data items. For example, the geographic secure zones may be utilized to present data items in a specific order related to location. In one aspect, when the mobile device  200 ,  400  determines that the mobile device  200 ,  400  is in a work zone, then information, e.g., in the contacts data item, may be arranged so that work contacts appear at the upper portion of a contacts listing. When the mobile device  200 ,  400  enters a home zone, the information in the contacts data item may be rearranged to present personal contacts at the upper portion of the contacts listing. Similarly, personnel secure zones may be utilized to organize data items according to personnel. For example, when the mobile device  200 ,  400  senses another mobile device  200 ,  400  that is associate with a specific zone, e.g., a work zone, then information related to the sensed mobile device  200 ,  400  or work information is organized to be viewed first by the mobile device  200 ,  400 . 
   Referring now to  FIG. 6 , a method  600  of operating a mobile device in accordance with another embodiment of the present invention is illustrated. The method  600  begins at step  602  and proceeds to sense for additional mobile devices within a predefined area at step  604 . At step  606 , it is determined whether predefined conditions regarding the particular data item to which a user requests access have been met. If the predefined conditions are met, then, at step  608  access is granted and the method ends at step  610 . If the predefined conditions are not met, then, at step  612  access is denied. At step  614 , the mobile device determines whether searching for other mobile devices should be continued. If searching is not continued, then the methods ends at step  610 . If the searching for other mobile devices is continued, then the method returns to step  604 . 
   It is thus believed that the operation and construction of various embodiments of the present invention will be apparent from the foregoing Detailed Description. While various devices have been described, it will be obvious to a person of ordinary skill in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention, as defined in the following claims. Therefore, the spirit and the scope of the appended claims should not be limited to the description of the embodiments contained herein.
