The present invention relates to biometrics and more particularly to the use of biometrics in application command and control.
Biometrics is the measurement and statistical analysis of the physical and behavioral characteristics of an individual. Biometrics are primarily used for surveillance, identification and access control. The basic premise of biometric authentication is that each person is unique and that an individual can be identified by his or her intrinsic physical or behavioral traits. Fingerprint recognition, as an example of biometrics, refers to the automated identification or confirmation of the identity of an individual based upon the comparison of two fingerprints—one acquired in real time and one previously acquired.
Fingerprint recognition is one of the most well known forms of biometrics, and fingerprint recognition is by far the most used biometric solution for authentication on computerized systems. The reason for the popularity of fingerprint recognition is the ease of acquisition, established use and acceptance when compared to other biometrics, and that each individual likely has ten inherent sources of fingerprint data—one for each finger. Generally, a fingerprint verification system includes several logical components including a fingerprint sensing component, in which the fingerprint of an individual is acquired by a fingerprint scanner to produce a raw digital representation, a fingerprint preprocessing component, in which the input fingerprint is enhanced and adapted to simplify the task of feature extraction, a fingerprint feature extraction component, in which the fingerprint is further processed to generate discriminative properties, also called feature vectors, and a fingerprint matching component, in which the feature vector of the input fingerprint is compared against one or more existing templates.
Fingerprint verifications systems have been successfully deployed in personal and mobile computing. Specifically, small fingerprint scanners have been embedded in the casement of a computing device and firmware executing at bootstrap of the device reads a fingerprint from an individual in order to authenticate the use of the device by the individual. As such, a high degree of data security can be provided on a mobile device by preventing the complete bootstrap of a device when encountering an individual with an invalid fingerprint scan. Optionally, as an additional layer of security, data resident on fixed storage in a device is encrypted and decryption of that data is only performed subsequent to the authentication of an authorized end user based upon fingerprint recognition.
Embodiments of the present invention address deficiencies of the art in respect to biometrics and provide a novel and non-obvious method, system and computer program product for biometric state switching. In an embodiment of the invention, a biometric state switching method includes storing in a database a multiplicity of different fingerprints, each in connection with a different state of a corresponding application. Thereafter, an end user is authenticated into use of a computing device by receiving in a fingerprint scanner affixed to the computing device a scanned fingerprint, matching the scanned fingerprint to one of the different fingerprints in the database, and if the scanned finger print matches one of the different fingerprints in the database, authenticating the end user into user of the computing device. Finally, subsequent to authentication, an application is executed in memory of the computing device, a state is identified for the application stored in connection with the one of the different fingerprints matched to the scanned fingerprint, and a state of execution of the application is set to the identified state.
In one aspect of the embodiment, a scan of a different fingerprint is received and matched to a different state of execution of the application. As such, the state of execution of the application is set to the different state. In another aspect of the embodiment, the multiplicity of different fingerprints is acquired by the fingerprint scanner and in yet another aspect of the embodiment, the database is disposed within the computing device. Finally, in even yet another aspect of the embodiment, the different fingerprint is of a different finger of the end user.
In another embodiment of the invention, a data processing system is configured for biometric state switching. The system includes a computing device with memory and at least one processor and a fingerprint scanner disposed upon an encasement of the computing device and coupled to the memory and at least one processor. The system also includes a database coupled to the computing device and storing a multiplicity of different fingerprints, each in connection with a different state of a corresponding application. Finally, the system includes a biometric state switching module. The module includes program code which when executing in the memory by the at least one processor, is enabled to authenticate an end user into use of the computing device by receiving in the fingerprint scanner a scanned fingerprint, match the scanned fingerprint to one of the different fingerprints in the database, and if the scanned finger print matches one of the different fingerprints in the database, authenticate the end user into user of the computing device, and subsequent to authentication, to execute an application in the memory of the computing device, identify a state for the application stored in connection with the one of the different fingerprints matched to the scanned fingerprint, and set a state of execution of the application to the identified state.
Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:
Embodiments of the invention provide for biometric state switching. In accordance with an embodiment of the invention, a multiplicity of different fingerprints from different fingers are stored in a database, each in association with a different application state. Thereafter, during bootstrap of a computing device, a fingerprint is acquired by a fingerprint scanner of the computing device and matched to one of the different fingerprints in the database. Upon matching the acquired fingerprint to one of the different fingerprints, a corresponding application state is identified and an application in the computing device is configured to a state consistent with the identified application state.
In further illustration,
Upon locating a matching fingerprint in the table 170, the biometric state switching logic 190 sets the corresponding state 180 for the corresponding one of the applications 130. In this way, different states for different ones of the applications 130 can be defined in the table 170 to correspond to different fingers of an end user. Consequently, the end user can rapidly apply different states to different ones of the applications 130 merely by swiping an appropriate one of the fingers of the end user across the fingerprint scanner 140.
The process described in connection with
Of note, a biometric state switching module 300 executes in the memory 220 by the processor 210. The biometric state switching module 300 includes program code enabled during execution by the processor to receive a fingerprint by way of the fingerprint scanner 280, to authenticate an end user according to the fingerprint using authentication processor 290, to execute one or more of the applications 260A, 260N, to locate in the fingerprint-to-state 270 a corresponding entry based upon the fingerprint and to identify a state for one of the applications 260A, 260N with respect to the entry. The program code yet further is enabled during execution to set the state of the one of the applications 260A, 260N to the identified state of the entry to the extent that the one of the applications 260A, 260N is executing in the memory 220.
In even yet further illustration of the operation of the biometric state switching module 300,
In block 340, at least one application is executed in the computing device, for instance an operating system or a computer program that operates by way of the operating system. In block 350, a state of one or more of the applications is located in a fingerprint-to-state table for the scanned fingerprint. In decision block 360, if no entry in the fingerprint-to-state table can be found for the scanned fingerprint, the process ends in block 390. But, in decision block 360, if an entry for the scanned fingerprint is found in the fingerprint-to-state table, in block 370 a state specified by the entry is applied to a corresponding one of the applications.
Finally, in block 380, it is determined if a new fingerprint is scanned to produce a new fingerprint. If so, the process returns to block 350 in which a new state of one or more of the applications is located in a fingerprint-to-state table for the scanned fingerprint. As such, once again in decision block 360, if no entry in the fingerprint-to-state table can be found for the scanned fingerprint, the process ends in block 390; but, in decision block 360, if an entry for the newly scanned fingerprint is found in the fingerprint-to-state table, in block 370 a state specified by the entry is applied to a corresponding one of the applications.
