Camera-steady focus requirements for preventing inconspicuous use of cameras on handheld mobile communication devices
View Patent ↗Methods and devices for implementing a camera restriction on a wireless handheld communication device. As more handheld devices incorporate camera functionalities, organizations and individuals with privacy concerns are more vulnerable to unauthorized disclosure. The camera restriction prevents a user from taking a picture of a subject if the device has not been steadily focused on the subject in question for a predetermined period of time. In short, this process extends the normal camera-taking procedure and thus requires the camera user to take pictures in a conspicuous manner—the rationale being that a camera user would be less likely to take unauthorized pictures if such actions could be easily recognized. The camera restriction can be communicated to the device via a wireless communication network. Additionally, the restrictions and boundaries can be communicated to the device as part of an IT security policy.
1. A method for preventing unauthorized photography comprising:
providing a device comprising at least one camera-assembly, at least one focus-sensing apparatus, and at least one actuator; and
configuring the device to allow saving image data received via the at least one camera-assembly when the at least one actuator has been engaged and a predetermined amount of time, during which focused-image data is sensed by the at least one focus-sensing apparatus, has elapsed since engagement of the at least one actuator.
2. The method as recited in claim 1 , wherein the predetermined amount of time during which focused-image data is sensed is sufficiently long to expose the unauthorized taking of photographs during the course of visually policing a restricted area.
3. The method as recited in claim 2 , wherein the predetermined amount of time is approximately ten seconds.
4. The method as recited in claim 2 , wherein the predetermined amount of time is approximately five seconds.
5. The method as recited in claim 1 , further comprising:
saving allowed image data at the device.
6. A method of preventing unauthorized acquisition of images in a restricted area comprising:
providing a device comprising at least one camera-assembly, at least one focus-sensing apparatus, and at least one actuator;
storing data at the device that defines geographical boundaries of a restricted operating area of the device;
ascertaining a present geographical position of the device and determining whether the device is presently located in the restricted operating area based on a comparison to the stored geographical boundaries of the restricted operating area; and
when it is determined that the device is located in the restricted area, allowing the saving of image data received via the at least one camera-assembly when the at least one actuator has been engaged and a predetermined amount of time, during which focused-image data is sensed by the at least one focus-sensing apparatus, has elapsed since engagement of the actuator.
7. The method as recited in claim 6 , wherein the device is configurable for signal communication with a network.
8. The method as recited in claim 6 , wherein the device further comprises an input device located between a display and a keyboard in a text communicating orientation.
9. The method as recited in claim 8 , wherein the input device is a navigation tool.
10. The method as recited in claim 6 , wherein the electronic device further comprises at least a first input device and a second input device.
11. The method as recited in claim 10 , wherein the first input device is a keyboard having alphabetic characters arranged in one of a QWERTY layout or QWERTZ layout, or AZERTY layout.
12. The method as recited in claim 10 , wherein first input device is a keyboard comprising a plurality of keys with which alphabetic characters are associated and wherein at least a portion of the individual keys has multiple characters associated therewith.
13. The method as recited in claim 10 , wherein the second input device includes a touch pad for controlling a cursor on a display.
14. The method as recited in claim 6 , wherein the predetermined amount of time is about eight seconds.
15. The method as recited in claim 6 , further comprising configuring the device to allow transmission of image data when saving of image data is allowed.
16. A device, comprising:
a camera assembly configured for taking photographs;
a focus sensor;
a time-actuator; and
a timer,
wherein the camera-assembly is configured to take a photograph when the time-actuator has been engaged, and an accumulation at the timer of a predetermined length of focus-time, sensed by the focus sensor, has occurred.
17. The device of claim 16 , wherein the predetermined length of focus-time is sufficiently long to expose unauthorized use of the device in the course of policing a restricted area.
18. The device of claim 16 , wherein the predetermined length of focus-time is approximately ten seconds.
19. The device of claim 16 , wherein the predetermined length of focus-time is approximately five seconds.
20. The device of claim 16 , wherein the predetermined length of focus-time is sufficiently long to expose an unauthorized shooter taking unauthorized photographs.
