Abstract

An electronic device, method, and computer program product automatically support fingerprint authentication using a fingerprint scanner on an opposite side even when the electronic device is detected as being grasped upside down. The electronic device includes front and back fingerprint scanners respectively exposed on front and back sides of a device housing. In response to determining that a requirement exists for scanning a fingerprint of a user while the electronic device is upside down, a controller of the electronic device triggers at least one of the front and the back fingerprint scanners to initiate scanning. The controller receives a fingerprint image from a corresponding one of the front and back fingerprint scanner. The controller authenticates the user in response to identifying that an upside-down version of the received fingerprint image corresponds to a fingerprint of an authorized user, based on authentication data stored in memory of the electronic device.

Dependent claims

An electronic device comprising:

a device housing having a front side and a back side;
a front fingerprint scanner exposed at the front side of the device housing at a front fingerprint scanner location that is in a lower portion of the front side when the electronic device is an upright position;
a back fingerprint scanner exposed at the back side of the device housing at a back fingerprint scanner location that is in a lower portion of the back side when the electronic device is the upright position;
a front display presented on the front side of the device housing;
a back display presented on the back side of the device housing;
a memory that stores authentication data;
at least one sensor configured to identify an orientation of the electronic device;
and
a controller communicatively coupled to the front and the back fingerprint scanners, the front and the back displays, the memory, and the at least one sensor, and which:
determines, based on input from the at least one sensor, whether the electronic device is in an upside-down orientation;
and
in response to determining that a requirement exists for scanning a fingerprint of a user while the electronic device is in the upside-down orientation:
triggers at least one of the front and the back fingerprint scanners to initiate scanning;
receives a fingerprint image from a corresponding one of the front and the back fingerprint scanner;
and
authenticates the user in response to identifying that an upside-down version of the received fingerprint image corresponds to a fingerprint of an authorized user, based on the authentication data.

A method comprising:

monitoring at least one sensor configured to identify an orientation of an electronic device comprising:
(i) a device housing having a front side and a back side;
(ii) a front fingerprint scanner exposed at the front side of the device housing at a front fingerprint scanner location that is in a lower portion of the front side when the electronic device is an upright position;
(iii) a back fingerprint scanner exposed at the back side of the device housing at a back fingerprint scanner location that is in a lower portion of the back side when the electronic device is the upright position;
(iv) a front display presented on the front side of the device housing;
and (v) a back display presented on the back side of the device housing;
determining, based on input from at least one sensor, whether the electronic device is in an upside-down orientation;
and
in response to determining that a requirement exists for scanning a fingerprint of a user while the electronic device is in the upside-down orientation:
triggering at least one of the front and the back fingerprint scanners to initiate scanning;
receiving a fingerprint image from a corresponding one of the front and the back fingerprint scanner;
and
authenticating the user in response to identifying that an upside-down version of the received fingerprint image corresponds to a fingerprint of an authorized user, based on authentication data stored in memory of the electronic device.

10 more elements

A computer program product comprising:

a computer readable storage device;
and
program code on the computer readable storage device that when executed by a processor associated with an electronic device, the program code enables the electronic device to provide functionality of:
monitoring at least one sensor configured to identify an orientation of the electronic device comprising:
(i) a device housing having a front side and a back side;
(ii) a front fingerprint scanner exposed at the front side of the device housing at a front fingerprint scanner location that is in a lower portion of the front side when the electronic device is an upright position;
(iii) a back fingerprint scanner exposed at the back side of the device housing at a back fingerprint scanner location that is in a lower portion of the back side when the electronic device is the upright position;
(iv) a front display presented on the front side of the device housing;
and (v) a back display presented on the back side of the device housing;
determining, based on input from at least one sensor, whether the electronic device is in an upside-down orientation;
and
in response to determining that a requirement exists for scanning a fingerprint of a user while the electronic device is in the upside-down orientation:
triggering at least one of the front and the back fingerprint scanners to initiate scanning;
receiving a fingerprint image from a corresponding one of the front and the back fingerprint scanner;
and
authenticating the user in response to identifying that an upside-down version of the received fingerprint image corresponds to a fingerprint of an authorized user, based on authentication data stored in memory of the electronic device.
