Abstract
Description
- 1. Field of the Invention
- The present invention relates generally to electronic systems. More particularly, the present invention relates to configuring electronic systems.
- 2. Background Art
- A shared device which can be used by any one of a number of authorized users, such as a Voice over Internet Protocol (VoIP) telephone, typically provides access to a user by requiring the user to manually input some form of identification data, such as a user ID and a password. The identification data is typically associated with a profile of the user, which may include a particular configuration of settings for the shared device. For example, a profile may include the personalized settings of the user and settings which grant the user access to a particular set of features in the shared device. Therefore, once a user provides the identification data, the profile of the user can be set in the shared device by adjusting the settings in the shared device in accordance with the configuration of settings included in the profile. However, requiring the user of the shared device to recall and manually enter the abovementioned identification data each time the shared device is to be used can greatly inconvenience the user.
- The known methods used to overcome the abovementioned difficulties associated with requiring the user to manually enter a user ID and password involve allowing the user to physically plug in a device representing a token into the shared device. In particular, one such known method involves the use of a USB device which can be plugged directly into a USB port that is provided on the shared device. The USB device can be associated with a particular user and can include the user's identification data as well as the profile of the user. However, the USB device can introduce significant drawbacks. For example, each user will typically be required to carry an assigned USB device with them at all times in order to gain access to the shared device, which can inconvenience the user since such USB devices can be bulky. Moreover, the USB port provided on the shared device typically includes an exposed metal pad, which can make the shared device more vulnerable to damage caused by electrostatic discharge (ESD) as well as increase the difficulty of passing an ESD test.
- Thus, there is a strong need in the art for a system, which allows convenient and secure profile setting in a shared device.
- There are provided systems and methods for secure profile setting in a shared device, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.
- The features and advantages of the present invention will become more readily apparent to those ordinarily skilled in the art after reviewing the following detailed description and accompanying drawings, wherein:
-
FIG. 1 is a block diagram illustrating a system for secure profile setting in a shared device, according to one embodiment of the present invention; -
FIG. 2 is a flow diagram illustrating a method for secure profile setting of at least one shared device, according to one embodiment of the present invention. -
FIG. 3 is a block diagram illustrating a system for secure profile setting in a shared device, according to one embodiment of the present invention; -
FIG. 4 is a flow diagram illustrating a method for secure profile setting of at least one shared device, according to one embodiment of the present invention. - Although the invention is described with respect to specific embodiments, the principles of the invention, as defined by the claims appended herein, can obviously be applied beyond the specifically described embodiments of the invention described herein. Moreover, in the description of the present invention, certain details have been left out in order to not obscure the inventive aspects of the invention. The details left out are within the knowledge of a person of ordinary skill in the art.
- The drawings in the present application and their accompanying detailed description are directed to merely example embodiments of the invention. To maintain brevity, other embodiments of the invention which use the principles of the present invention are not specifically described in the present application and are not specifically illustrated by the present drawings. It should be borne in mind that, unless noted otherwise, like or corresponding elements among the figures may be indicated by like or corresponding reference numerals.
-
FIG. 1 shows a block diagram of an exemplary system for secure profile setting in a shared device in accordance with one embodiment of the invention.System 100 inFIG. 1 includesshared device 102,RFID transponder module 104, anddatabase 106. Shareddevice 102 can be, for example, any device that be used and configured by multiple users, such as a VoIP telephone, a laptop computer, or a cellular telephone. - As shown in
FIG. 1 , shareddevice 102 includes central processing unit (CPU) 108 and radio frequency identification (RFID)reader module 110. As also shown inFIG. 1 ,CPU 108 can communicate withRFID reader module 110 viabus 112.RFID reader module 110 can be, for example, an RFID reader that is embedded in shareddevice 102. As also shown inFIG. 1 ,system 100 includesRFID transponder module 104, which can communicate with shareddevice 102 viaRFID reader module 110 in a manner known in the art. For example,RFID transponder module 104 andRFID reader module 110 can establish a communication link between one another, such ascommunication link 116, using radio frequency signals. - As further shown in
FIG. 1 ,system 100 includesdatabase 106, which is in communication with shareddevice 102 viacommunication path 114.Communication path 114, for example, can be a physical connection, such as a bus, or a wired or wireless data link that enables communication over a network.Database 106, for example, can be a database that is accessible over a network. In one embodiment, shareddevice 102 can be configured to cache a copy ofdatabase 106 and to access the cached copy ofdatabase 106 locally.Database 106, for example, can include a number of profiles, where each profile includes a configuration of settings for shareddevice 102. The configuration of settings can include, for example, the personalized settings of the user and settings which grant the user access to a particular set of features in shareddevice 102. Accordingly, each profile indatabase 106 can correspond to a particular user of shareddevice 102. -
RFID transponder module 104 inFIG. 1 can include, for example, a chip-based RFID tag capable of storing data and transmitting data to an RFID reader using radio frequency signals. For example,RFID transponder module 104 can store authentication data that can be used by shareddevice 102 to establish the identity of a user, such as a number associated with a particular user (e.g., an employee number) or biometric authentication data associated with a particular user, such as a fingerprint template or a voice template. It should be noted that althoughFIG. 1 depicts a single RFID transponder module (i.e., RFID transponder module 104),system 100 can include additional RFID transponder modules. Moreover,system 100 can include additional shared devices. Thus, inexemplary system 100, each user of shareddevice 102 can be associated with a particular RFID transponder module, such asRFID transponder module 104. -
FIG. 2 illustratesflowchart 200 for performing an exemplary method for secure profile setting in a shared device in accordance with one embodiment of the present invention. As shown inFIG. 2 , atstep 202 offlowchart 200, the method for secure profile setting can be initiated by a signal transmitted fromRFID transponder module 104 inFIG. 1 , which can be associated with a user of shareddevice 102. For example, the user may placeRFID transponder module 104 within a suitable range of shareddevice 102 to allowcommunication link 116 to be established betweenRFID transponder module 104 andRFID reader module 110 embedded in shareddevice 102.Communication link 116 can be established, for example, whenRFID transponder module 104 receives adequate incoming radio frequency signals fromRFID reader module 110 which then enablesRFID transponder module 104 to transmit a signal back toRFID reader module 110. Thus, in one exemplary embodiment of the invention, shareddevice 102 inFIG. 1 can be a VoIP telephone having an embedded RFID reader module. In such an embodiment, a user can place the associated RFID transponder module within a suitable range of the VoIP telephone to allow a communication link to be established between the RFID transponder module and the embedded RFID reader module using radio frequency signals. - As shown in
FIG. 2 , atstep 204 offlowchart 200, the signal transmitted byRFID transponder module 104 toRFID reader module 110 is used by shareddevice 102 to identify the user. As previously discussed,RFID transponder module 104 can include a chip-based RFID tag that is capable of storing data and transmitting the stored data. Thus, the signal transmitted byRFID transponder module 110 can include various types of authentication data that can be associated with the user, such as biometric authentication data. For example,RFID transponder module 104 can include biometric authentication data associated with a particular user, such as a fingerprint template or a voice template. Therefore, onceRFID reader module 110 acquires the authentication data fromRFID transponder module 104,RFID reader module 110 can provide the authentication data toCPU 108 viabus 112 to properly identify the user. For example, the user may be prompted by shareddevice 102 to provide a voice sample, which can be achieved by having the user speak into a microphone coupled to shared device 102 (not shown inFIG. 1 ). The voice sample can then be compared to the voice template acquired fromRFID transponder module 104, and if the voice sample matches the voice template, the user can be positively identified by shareddevice 102. - As shown in
FIG. 2 , atstep 206 offlowchart 200, shareddevice 102 retrieves a profile stored indatabase 106 that corresponds to the user identified instep 204. As previously mentioned,database 106 can include a number of profiles, such that each profile corresponds to a particular user. Therefore, once the identity of a user is established instep 204, shareddevice 102 can proceed to querydatabase 106, for example, for the profile corresponding to the identified user and can retrieve the profile viacommunication path 114. - As shown in
FIG. 2 , atstep 208 offlowchart 200, the profile retrieved instep 206 is set in shareddevice 102 by determining from the profile, for example, a configuration of settings for shareddevice 102. The configuration of settings can include, for example, the personalized settings of the user and other settings which can grant the user access to a particular set of features in shareddevice 102. For example, in the embodiment of the invention where shareddevice 102 is a VoIP telephone, a user's profile may require that the volume on the VoIP telephone be set to a particular level and to bill calls placed by the user to a particular account. Thus, once the configuration of settings are determined from the profile, the profile can be set in shareddevice 102 by adjusting the settings in shareddevice 102 in accordance with the configuration of settings included in the user's profile. -
FIG. 3 shows a block diagram of an exemplary system for secure profile setting in a shared device in accordance with one embodiment of the invention.System 300 inFIG. 3 includes shareddevice 302, which includesCPU 308,RFID reader module 310, andbus 312.System 300 further includesdatabase 306 andcommunication path 314.Shared device 302,CPU 308,RFID reader module 310,bus 312,database 306, andcommunication path 314 inFIG. 3 correspond to shareddevice 102,CPU 108,RFID reader module 110,bus 112,database 106, andcommunication path 114 inFIG. 1 , respectively.System 300 further includesRFID transponder module 304. - As shown in
FIG. 3 ,RFID transponder module 304 includesRFID tag 318 andfingerprint scanner module 322.Fingerprint scanner module 322 can communicate withRFID tag 318 viabus 320.Fingerprint scanner module 322 can include a fingerprint scanner which can be used to acquire fingerprint data directly from the user.Fingerprint scanner module 322 can further include a microchip which can compare the acquired fingerprint data to a fingerprint template stored inRFID tag 318 to determine if there is a match, in which case the user can be positively identified as the person associated withRFID transponder module 304. For example,RFID transponder module 304 can be configured to transmit a signal toRFID reader module 310 only if the acquired fingerprint data matches the fingerprint template stored inRFID tag 318. Thus, the signal can include identification data, such as a name or an employee number of the user, which can allow shareddevice 302 to establish the identity of the user and to eventually grant the user access to shareddevice 302. - In another embodiment, the abovementioned microchip can be included in
RFID reader module 310. In such an embodiment,RFID transponder module 304 can be configured to transmit a signal toRFID reader module 310 that includes both the acquired fingerprint data and the fingerprint template stored inRFID tag 318. As such, the acquired fingerprint data and the fingerprint template can be compared using the microchip included inRFID module 304 to determine if there is a match, in which case the user can be positively identified. Thus, a non-authorized user whose fingerprint data does not match the fingerprint template stored in the RFID tag of a particular RFID transponder module cannot gain access to the shared device. -
FIG. 4 illustratesflowchart 400 for performing an exemplary method for secure profile setting in a shared device in accordance with one embodiment of the present invention. As shown inFIG. 4 , atstep 402 offlowchart 400, the method for secure profile setting can be initiated by acquiring the user's fingerprint data usingfingerprint scanner module 322 included inRFID transponder module 304. Thereafter, atdecision step 404, the fingerprint data is compared to the fingerprint template stored inRFID tag 318 to determine if there is a match. If the there is no match, step 402 can be repeated. If there is a match, then atstep 406, a signal is transmitted fromRFID transponder module 304 to shareddevice 302. For example, the user may placeRFID transponder module 304 within a suitable range of shareddevice 302 to allowcommunication link 316 to be established betweenRFID transponder module 304 andRFID reader module 310 embedded in shareddevice 302.Communication link 316 can be established, for example, whenRFID transponder module 304 receives adequate incoming radio frequency signals fromRFID reader module 310 which then enablesRFID transponder module 304 to transmit a signal back toRFID reader module 310. - As shown in
FIG. 4 , atstep 408 offlowchart 400, the signal transmitted byRFID transponder module 304 toRFID reader module 310 is used by shareddevice 302 to identify the user. SinceRFID tag 318 can be a chip-based RFID tag that is capable of storing data and transmitting the stored data, the signal transmitted byRFID transponder module 304 can include various types of authentication data that can be associated with the user, such as a name of the user, an employee number, or biometric authentication data. Therefore, onceRFID reader module 310 acquires the authentication data fromRFID transponder module 304,RFID reader module 310 can provide the authentication data toCPU 308 viabus 312 to properly identify the user. - As shown in
FIG. 4 , atstep 410 offlowchart 400, shareddevice 302 retrieves a profile stored indatabase 306 that corresponds to the user identified instep 408. As previously mentioned,database 306 can include a number of profiles, such that each profile corresponds to a particular user. Therefore, once the identity of a user is established instep 408, shareddevice 302 can proceed to querydatabase 306, for example, for the profile corresponding to the identified user and can retrieve the profile viacommunication path 314. - As shown in
FIG. 4 , atstep 412 offlowchart 400, the profile retrieved instep 410 is set in shareddevice 302 by determining from the profile, for example, a configuration of settings for shareddevice 302. The configuration of settings can include, for example, the personalized settings of the user and other settings which can grant the user access to a particular set of features in shareddevice 302. For example, in the embodiment of the invention where shareddevice 302 is a VoIP telephone, a user's profile may require that the volume on the VoIP telephone be set to a particular level and to bill calls placed by the user to a particular account. Thus, once the configuration of settings are determined from the profile, the profile can be set in shareddevice 302 by adjusting the settings in shareddevice 302 in accordance with the configuration of settings included in the user's profile. - Therefore, the present invention can be implemented in various shared devices where a user's profile can be set in the shared device. For example, the invention can be implemented in a corporate cellular telephone which can be shared among a number of associates in a corporation or a telecommunication terminal, such as a VoIP telephone terminal, that is coupled to a network. The invention can also be implemented in a computer terminal that is coupled to a network as well as a laptop computer or other portable electronic device. Furthermore, the invention can be implemented in a motor vehicle, for example, by allowing a user to set a profile in the motor vehicle which includes the user's seating and mirror positions or other types of settings preferred by a user.
- Thus, the invention enables a user to set a profile in a shared device by placing an RFID transponder module (e.g., RFID transponder module 104) associated with the user within a suitable range of the shared device to establish a communication link (e.g., communication link is 116) between the RFID transponder module and the RFID reader module embedded in the shared device. Moreover, the abovementioned exemplary security features of the invention, such as the fingerprint scanner that may be included in the RFID transponder module, can provide secure profile setting in the shared device by ensuring that the user of the shared device is authorized to use the shared device.
- In contrast to the conventional system including the USB device discussed above, the present invention can be implemented without inconveniencing the user of the shared device. For example, since the RFID transponder module of the present invention can include a small RFID tag, the RFID transponder module can be conveniently placed in an identification badge or other small object which a user, for example, is already required to carry. Consequently, the present invention advantageously avoids requiring the user to carry additional bulky devices, such as a USB device.
- In further contrast to the conventional system including the USB device, the present invention's ability to set a profile in a shared device by the transmission of data between an RFID transponder module and an RFID reader module embedded in the shared device can advantageously maintain the electrical isolation of the shared device. More specifically, since the present invention does not require additional ports to be included on the shared device, such as a USB port, the present invention does not introduce any exposed metal pads which can increase the shared device's vulnerability to damage caused by ESD and which can increase the difficulty of passing an ESD test.
- From the above description of the invention it is manifest that various techniques can be used for implementing the concepts of the present invention without departing from its scope. Moreover, while the invention has been described with specific reference to certain embodiments, a person of ordinary skill in the art would recognize that changes can be made in form and detail without departing from the spirit and the scope of the invention. For example, it is contemplated that the circuitry disclosed herein can be implemented in software, or vice versa. The described embodiments are to be considered in all respects as illustrative and not restrictive. It should also be understood that the invention is not limited to the particular embodiments described herein, but is capable of many rearrangements, modifications, and substitutions without departing from the scope of the invention.
