## Title
Controlling enterprise data on mobile device via the use of a tag index

## Abstract

A method, system and computer program product for controlling enterprise data on mobile devices. Data on a mobile device is tagged as being associated with either enterprise data or with personal data. Upon identifying the storage location of the tagged data and the identifier of the application that generated the tagged data, the tag, the storage location of the tagged data and the identifier of the application are stored in an index. A mobile agent residing on the mobile device may be directed by a mobile device management server of the enterprise to perform various actions (e.g., deleting, encrypting, backing-up) on the enterprise data using the index. In this manner, the enterprise has the ability to control their applications and data that resides on employees' mobile devices to ensure that such data is not lost or used in a manner that is contrary to the wishes of the employer.

## Background
TECHNICAL FIELD
The present invention relates generally to mobile devices, and more particularly to controlling enterprise data on mobile devices via the use of a tag index.
BACKGROUND
A mobile device (also known as a handheld device, handheld computer or simply handheld) is a small, hand-held computing device, typically having a display screen with touch input and/or a miniature keyboard and weighting less than 2 pounds (0.91 kg). Examples of mobile devices include a mobile phone, a cellular phone, a smartphone, a person digital assistant (PDA), an index personal computer and the like.
Such devices are being used more and more by employees of enterprises (referring to businesses, companies, government entities, etc.) enabling the employees to work from remote locations. These mobile devices are often owned by the employees as opposed to the employers.
Employees that are performing work on their mobile devices may be storing enterprise data on the mobile devices. Enterprise data on the mobile device may come from various sources, such as from enterprise applications, attachments in personal e-mails and so forth. However, the enterprise does not have any control over their applications or data that resides on these mobile devices which may have ramifications. For example, if the user lost his/her mobile device, then the enterprise data, which may be confidential, on the mobile device may be accessible by third parties, especially if the data is not encrypted or secured in some manner. In another example, if the user leaves the enterprise, then the former employee may have the freedom to dispense with the enterprise data in a manner that may be contrary to the wishes of the former employer.
As a result, the enterprise needs the ability to control their applications and data that resides on employees' mobile devices to ensure that such data is not lost or used in a manner that is contrary to the wishes of the employer.
BRIEF SUMMARY
In one embodiment of the present invention, a method for controlling enterprise data on mobile devices comprises tagging data on a mobile device as being associated with either enterprise data or personal data with a tag. The method further comprises identifying a storage location of the tagged data. Additionally, the method comprises obtaining an identifier of an application that generated the tagged data. In addition, the method comprises storing, by a processor, the tag, the storage location of the tagged data and the identifier of the application in an index.
Other forms of the embodiment of the method described above are in a system and in a computer program product.
The foregoing has outlined rather generally the features and technical advantages of one or more embodiments of the present invention in order that the detailed description of the present invention that follows may be better understood. Additional features and advantages of the present invention will be described hereinafter which may form the subject of the claims of the present invention.

DETAILED DESCRIPTION
The present invention comprises a method, system and computer program product for controlling enterprise data on mobile devices. In one embodiment of the present invention, data on a mobile device is tagged as being associated with either enterprise data or with personal data. Upon identifying the storage location of the tagged data and obtaining the identifier of the application that generated the tagged data, the tag, the storage location of the tagged data and the identifier of the application are stored in an index (referred to herein as the “tag index”). A mobile agent residing on the mobile device may be directed by a mobile device management server of the enterprise to perform various actions on the enterprise data, such as deleting, backing-up, encrypting, applying access control, etc. using the tag index. In this manner, the enterprise has the ability to control their applications and data that resides on employees' mobile devices to ensure that such data is not lost or used in a manner that is contrary to the wishes of the employer.
In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without such specific details. In other instances, well-known circuits have been shown in block diagram form in order not to obscure the present invention in unnecessary detail. For the most part, details considering timing considerations and the like have been omitted inasmuch as such details are not necessary to obtain a complete understanding of the present invention and are within the skills of persons of ordinary skill in the relevant art.
Referring now to the Figures in detail, FIG. 1 illustrates a network system 100 configured in accordance with an embodiment of the present invention. Network system 100 includes a mobile device 101 in wireless communication with a server (mobile device management server) 102 via a network 103. Mobile device 101 may be any mobile computing device, including, but not limited to, a mobile phone, a cellular phone, a smartphone, a personal digital assistance (PDA), a gaming unit, a portable computing unit, a tablet personal computer, and the like. System 100 may include any number of mobile devices 101 and the depiction of a single mobile device 101 is for illustrative purposes. A description of one embodiment of the hardware configuration of mobile device 101 is provided below in connection with FIG. 2.
As discussed above, mobile device 101 is in wireless communication with a management server 102 via a network 103, which may be, for example, a wireless wide area network, a circuit-switched telephone network, a Global System for Mobile Communications (GSM) network, Wireless Application Protocol (WAP) network, a WiFi network, an IEEE 802.11 standards network, various combinations thereof, etc. Other networks, whose descriptions are omitted here for brevity, may also be used in conjunction with system 100 of FIG. 1 without departing from the scope of the present invention.
Management server 102 is configured to manage the enterprise data being stored on mobile device 101 as discussed further below. In particular, management server 102 may reside at an enterprise (e.g., company, business, government entity) and attempt to control their applications and data residing on mobile device 101 by issuing commands to a software agent 104, such as a mobile agent, residing on mobile device 101 directed to performing various actions on the enterprise data, such as deleting, backing-up, encrypting, applying access control, etc. Mobile agent 104 is configured to implement the commands received from management server 102.
Additionally, mobile device 101 includes a software component referred to herein as the “tagging mechanism” 105 configured to tag the data on mobile 101 as being either enterprise data or personal data. In one embodiment, mobile device 101 includes different tagging mechanisms, such as the “auto tagging” mechanism, the “application assisted tagging” mechanism and the “user defined tagging” mechanism as discussed further below in connection with FIGS. 5-8. Tagging mechanism 105 represents any or all of these different tagging mechanisms.
Referring now to FIG. 2, FIG. 2 illustrates a hardware configuration of mobile device 101 which is representative of a hardware environment for practicing the present invention. Referring to FIG. 2, mobile device 101 has a processor 201 coupled to various other components by system bus 202. An operating system 203 runs on processor 201 and provides control and coordinates the functions of the various components of FIG. 2. An application 204 in accordance with the principles of the present invention runs in conjunction with operating system 203 and provides calls to operating system 203 where the calls implement the various functions or services to be performed by application 204. Application 204 may include, for example, a mobile agent 104 (FIG. 1) and tagging mechanism 105 (FIG. 1) configured to control enterprise data on mobile device 101, as discussed further below in association with FIGS. 3-11.
Referring again to FIG. 2, read-only memory (“ROM”) 205 is coupled to system bus 202 and includes a basic input/output system (“BIOS”) that controls certain basic functions of mobile device 101. Random access memory (“RAM”) 206 and disk adapter 207 are also coupled to system bus 202. It should be noted that software components including operating system 203 and application 204 may be loaded into RAM 206, which may be mobile device's 101 main memory for execution. Disk adapter 207 may be an integrated drive electronics (“IDE”) adapter that communicates with a disk unit 208, e.g., disk drive.
Mobile device 101 may further include a communications adapter 209 coupled to bus 202. Communications adapter 209 interconnects bus 202 with an outside network (network 103 of FIG. 1) thereby enabling mobile device 101 to communicate with management server 102 (FIG. 1).
I/O devices may also be connected to mobile device 101 via a user interface adapter 210 and a display adapter 211. Keyboard 212, mouse 213 and speaker 214 may all be interconnected to bus 202 through user interface adapter 210. Data may be inputted to mobile device 101 through any of these devices. A display monitor 215 may be connected to system bus 202 by display adapter 211. In this manner, a user is capable of inputting to mobile device 101 through keyboard 212 or mouse 213 and receiving output from mobile device 101 via display 215 or speaker 214. Other input mechanisms may be used to input data to mobile device 101 that is not shown in FIG. 2, such as display 215 having touch-screen capability.

As stated in the Background section, employees that are performing work on their mobile devices may be storing enterprise data on the mobile devices. Enterprise data on the mobile device may come from various sources, such as from enterprise applications, attachments in personal e-mails and so forth. However, the enterprise does not have any control over their applications or data that resides on these mobile devices which may have ramifications. For example, if the user lost his/her mobile device, then the enterprise data, which may be confidential, on the mobile device may be accessible by third parties, especially if the data is not encrypted or secured in some manner. In another example, if the user leaves the enterprise, then the former employee may have the freedom to dispense with the enterprise data in a manner that may be contrary to the wishes of the former employer. As a result, the enterprise needs the ability to control their applications and data that resides on employees' mobile devices to ensure that such data is not lost or used in a manner that is contrary to the wishes of the employer.
The principles of the present invention provide a means for the enterprise to control their applications and data that resides on employees' mobile devices to ensure that such data is not lost or used in a manner that is contrary to the wishes of the employer as discussed further below in connection with FIGS. 3-11. FIG. 3 is a flowchart of a method for controlling enterprise data on a mobile device via the use of a tag index. FIG. 4 illustrates a tag index for storing a tag, a storage location of the tagged data and an identifier of the application that generated the tagged data. FIG. 5 is a flowchart of a method for performing what is referred to herein as “auto tagging” through a kernel intercept. FIG. 6 illustrates the software components used in connection with performing auto tagging. FIG. 7 is a flowchart of a method for performing what is referred to herein as “application assisted tagging.” FIG. 8 is a flowchart of a method for performing what is referred to herein as “user defined tagging.” FIG. 9 is a flowchart of a method for implementing an arbitration policy to handle the situation of multiple tagging mechanisms tagging the same data. FIG. 10 is a flowchart of a method for implementing an arbitration policy to handle the situation of having different tags being associated with the same tagged data. FIG. 11 is a flowchart of a method for controlling the enterprise data on the mobile device in response to commands issued by the mobile device management server.
As stated above, FIG. 3 is a flowchart of a method 300 for controlling enterprise data on mobile device 101 via the use of a tag index in accordance with an embodiment of the present invention.
Referring to FIG. 3, in conjunction with FIGS. 1-2, in step 301, tagging mechanism 105 tags data on mobile device 101 as being associated with either enterprise or personal data. In one embodiment, there are various mechanisms for tagging data on mobile device 101 as being associated with either enterprise or personal data. When the data is tagged as being enterprise data, the “tag” corresponds to “enterprise.” When the data is tagged as being personal data, the “tag” corresponds to “personal.” In one embodiment, different tagging mechanisms may be used to tag the data on mobile device 101, such as the “auto tagging” mechanism, the “application assisted tagging” mechanism and the “user defined tagging” mechanism as discussed further below in connection with FIGS. 5-8. In each of these tagging mechanisms, in addition to tagging the data on mobile device 101 as being associated with either enterprise or personal data, a storage location of the tagged data and an identifier of the application that generated the tagged data are obtained as discussed further below in connection with FIG. 3.
In step 302, tagging mechanism 105 identifies a storage location of the tagged data. In step 303, tagging mechanism 105 obtains an identifier of the application that generated the tagged data.
In step 304, tagging mechanism 105 stores the tag, the storage location of the tagged data and the identifier of the application that generated the tagged data in an index as illustrated in FIG. 4.
FIG. 4 illustrates a tag index 400 for storing a tag 401, a storage location 402 of the tagged data and an identifier 403 of the application that generated the tagged data in accordance with an embodiment of the present invention. Referring to FIG. 4, index 400 includes tags, such as “enterprise” and “personal” well as the location of the tagged data. For example, the data tagged as being “enterprise” data resides at “/data/data/com.ibm.lotustraveller/files.” In another example, the data tagged as being “personal” data resides at “data/data/com.gmail.com/myMail.txt.” Index 400 further stores an identifier 403 of the application that generated the tagged data. For example, the data tagged as being “enterprise” data was generated by Notes® Traveler. The data tagged as being “personal” data was generated by Gmail®. In one embodiment, index 400 is stored in disk unit 208. In another embodiment, index 400 is stored in the user space of operating system 203 as discussed further below in connection with FIG. 6.
By having index 400 store a tag 401, a storage location 402 of the tagged data and an identifier 403 of the application that generated the tagged data, enterprises will be able to control their enterprise data (e.g., deleting, encrypting, backing-up, applying access control) on mobile device 101 as discussed further below.
In some implementations, method 300 may include other and/or additional steps that, for clarity, are not depicted. Further, in some implementations, method 300 may be executed in a different order presented and that the order presented in the discussion of FIG. 3 is illustrative. Additionally, in some implementations, certain steps in method 300 may be executed in a substantially simultaneous manner or may be omitted.
As discussed above, in one embodiment, the principles of the present invention may implement multiple tagging mechanisms. FIG. 5 is a flowchart of a method 500 for performing what is referred to herein as “auto tagging” through a kernel intercept in accordance with an embodiment of the present invention. FIG. 5 will be discussed in conjunction with FIG. 6, which illustrates the software components used in connection with performing auto tagging in accordance with an embodiment of the present invention.
Referring to FIG. 6, a conventional operating system 203 (FIG. 2) usually segregates the virtual memory into user space 601 and kernel space 602. User space 601 is the memory area where all user mode applications work; whereas, kernel space 602 is strictly reserved for running the kernel, kernel extensions, and most device drivers. Kernel space 602 includes a software component referred to as a “system call interceptor” 603 and user space 601 includes a software component referred to as a “package manager” 604 as well as index 400. A further description of these software components will be provided in connection with the discussion of FIG. 5.
Referring now to FIG. 5, in conjunction with FIGS. 1, 2 and 6, in step 501, system call interceptor 603 in kernel space 602 receives a system call from an application (e.g., Facebook®). A system call may refer to how an application requests a service (e.g., write data) from an operating system's kernel.
In step 502, system call interceptor 603 obtains the user identifier of the requesting application as well as the tag corresponding to the user identifier from package manager 604. In one embodiment, package manager 604 is a collection of software tools to automate the process of installing, upgrading, configuring and removing software packages for a computer's operating system 203 in a consistent manner. In one embodiment, package manager 604 maintains a database that includes the user identifications of applications as well as the tags (e.g., enterprise, personal) associated with such applications. For example, in one embodiment, all data generated by an application may be deemed to be enterprise data. As a result, the tag associated with the user identification of that application would correspond to “enterprise.”
In step 503, system call interceptor 603 stores the tag (obtained in step 502), the location of the tagged data (i.e., the location of the data to be written as requested by the application) and the identifier of the application (system call interceptor 603 obtains the identifier of the application when the application issues the system call to the system call interceptor 603) in index 400.
In some implementations, method 500 may include other and/or additional steps that, for clarity, are not depicted. Further, in some implementations, method 500 may be executed in a different order presented and that the order presented in the discussion of FIG. 5 is illustrative. Additionally, in some implementations, certain steps in method 500 may be executed in a substantially simultaneous manner or may be omitted.
Another mechanism for tagging is discussed in connection with FIG. 7. FIG. 7 is a flowchart of a method 700 for performing what is referred to herein as “application assisted tagging” in accordance with an embodiment of the present invention.
Referring to FIG. 7, in conjunction with FIGS. 1-2, in step 701, tagging mechanism 105 receives an identifier of the application (e.g., Gmail®) as well as the tag and location of the tagged data from the application.
In step 702, tagging mechanism 105 stores the tag, the location of the tagged data and the identifier of the application in an entry of index 400.
In some implementations, method 700 may include other and/or additional steps that, for clarity, are not depicted. Further, in some implementations, method 700 may be executed in a different order presented and that the order presented in the discussion of FIG. 7 is illustrative. Additionally, in some implementations, certain steps in method 700 may be executed in a substantially simultaneous manner or may be omitted.
Another mechanism for tagging is discussed in connection with FIG. 8. FIG. 8 is a flowchart of a method 800 of performing what is referred to herein as “user defined tagging” in accordance with an embodiment of the present invention.
Referring to FIG. 8, in conjunction with FIGS. 1-2, in step 801, tagging mechanism 105 prompts the user to select a tag (e.g., enterprise, personal) for application data.
In step 802, tagging mechanism 105 receives the selected tag from the user.
In step 803, tagging mechanism 105 stores the tag, the location of the tagged data and the identifier of the application in an entry of index 400.
In some implementations, method 800 may include other and/or additional steps that, for clarity, are not depicted. Further, in some implementations, method 800 may be executed in a different order presented and that the order presented in the discussion of FIG. 8 is illustrative. Additionally, in some implementations, certain steps in method 800 may be executed in a substantially simultaneous manner or may be omitted.
As a result of having multiple tagging mechanisms, there may be times when multiple tagging mechanisms tag the same data or having different tags being associated with the same tagged data. In such scenarios, arbitration policies are implemented to handle such situations as discussed below in connection with FIGS. 9-10.
FIG. 9 is a flowchart of a method 900 for implementing an arbitration policy to handle the situation of multiple tagging mechanisms tagging the same data in accordance with an embodiment of the present invention.
Referring to FIG. 9, in conjunction with FIGS. 1-2, in step 901, mobile agent 104 determines if the data has been previously tagged by a different mechanism. If the data has not been previously tagged by a different mechanism, then mobile agent 104 continues to determine if there is data that has been previously tagged by a different mechanism in step 901.
If, however, the data has been previously tagged by a different mechanism, then, in step 902, mobile agent 104 implements an arbitration policy to select the appropriate tagging mechanism. For example, the arbitration policy may be that “auto tagging” always takes priority over “application assisted tagging” which takes priority over “user defined tagging.”
In some implementations, method 900 may include other and/or additional steps that, for clarity, are not depicted. Further, in some implementations, method 900 may be executed in a different order presented and that the order presented in the discussion of FIG. 9 is illustrative. Additionally, in some implementations, certain steps in method 900 may be executed in a substantially simultaneous manner or may be omitted.
FIG. 10 is a flowchart of a method 1000 for implementing an arbitration policy to handle the situation of having different tags being associated with the same tagged data in accordance with an embodiment of the present invention.
Referring to FIG. 10, in conjunction with FIGS. 1-2, in step 1001, mobile agent 104 determines if the data has been previously assigned a different tag. For example, one mechanism may assign the tag of “enterprise” while another mechanism may assign the tag of “personal” to the same data. If the data has not been previously assigned a different tag, then mobile agent 104 continues to determine if the data has been previously assigned a different tag in step 1001.
If, however, the data has been previously assigned a different tag, then, in step 1002, mobile agent 104 implements an arbitration policy to select the appropriate tag. For example, the arbitration policy may be that the “enterprise” tag always takes priority over the “application” tag.
In some implementations, method 1000 may include other and/or additional steps that, for clarity, are not depicted. Further, in some implementations, method 1000 may be executed in a different order presented and that the order presented in the discussion of FIG. 10 is illustrative. Additionally, in some implementations, certain steps in method 1000 may be executed in a substantially simultaneous manner or may be omitted.
As discussed above, index 400 is used to enable the enterprise to control their enterprise data (e.g., deleting, encrypting, backing-up, applying access control) on mobile device 101. A manner of using index 400 to enact such control is discussed below in connection with FIG. 11.
FIG. 11 is a flowchart of a method 1100 for controlling the enterprise data on mobile device 101 (FIGS. 1 and 2) in response to commands issued by mobile device management server 102 (FIG. 1) in accordance with an embodiment of the present invention.
Referring to FIG. 11, in conjunction with FIGS. 1-2, in step 1101, a determination is made by mobile agent 104 as to whether it received a request from management server 102 to delete all or a selected portion of the data tagged as being enterprise data.
If mobile agent 104 received a request from management server 102 to delete all or a selected portion of the data tagged as enterprise data, then, in step 1102, mobile agent 104 identifies the storage location of the tagged data to be deleted using index 400. In step 1103, mobile agent 104 deletes the tagged data requested to be deleted.
If, however, mobile agent 104 did not receive a request from management server 102 to delete all or a selected portion of the data tagged as enterprise data, then, in step 1104 a determination is made by mobile agent 104 as to whether it received a request from management server 102 to back-up all or a selected portion of data tagged as being enterprise data.
If mobile agent 104 received a request from management server 102 to back-up all or a selected portion of the data tagged as enterprise data, then, in step 1105, mobile agent 104 identifies the storage location of the tagged data to be backed-up using index 400. In step 1106, mobile agent 104 backs-up the tagged data requested to be backed-up.
If, however, mobile agent 104 did not receive a request from management server 102 to back-up all or a selected portion of the data tagged as enterprise data, then, in step 1107 a determination is made by mobile agent 104 as to whether it received a request from management server 102 to encrypt all or a selected portion of data tagged as being enterprise data.
If mobile agent 104 received a request from management server 102 to encrypt all or a selected portion of the data tagged as enterprise data, then, in step 1108, mobile agent 104 identifies the storage location of the tagged data to be encrypted using index 400. In step 1109, mobile agent 104 encrypts the tagged data requested to be encrypted.
If, however, mobile agent 104 did not receive a request from management server 102 to encrypt all or a selected portion of the data tagged as enterprise data, then, in step 1110 a determination is made by mobile agent 104 as to whether it received a request from management server 102 to apply access control to all or a selected portion of data tagged as being enterprise data.
If mobile agent 104 received a request from management server 102 to apply access control to all or a selected portion of the data tagged as enterprise data, then, in step 1111, mobile agent 104 identifies the storage location of the tagged data to have applied access control using index 400. In step 1112, mobile agent 104 applies access control on the tagged data requested to have applied access control.
If, however, mobile agent 104 did not receive a request from management server 102 to apply access control to all or a selected portion of the data tagged as enterprise data, then a determination is made by mobile agent 104 in step 1101 as to whether it received a request from management server 102 to delete all or a selected portion of the data tagged as being enterprise data.
In some implementations, method 1100 may include other and/or additional steps that, for clarity, are not depicted.
