Abstract
A device may capture an image in a portable device, embed a watermark into the image in the portable device, and transmit the watermarked image through a wireless interface of the portable device.
Claims20
A method comprising:
- accessing an image in a portable device;
- receiving a first copy protection parameter for the image;
- receiving a second copy protection parameter for the image;
- in response to determining the second copy protection parameter conflicts with the first copy protection parameter, rejecting the second copy protection parameter;
- determining that the image is about to be transmitted from the portable device to another device;
- in response to determining that the image is about to be transmitted:
- determining whether a watermarked version of the image is stored in the portable device;
- in response to determining a watermarked version of the image is not stored in the portable device, automatically selecting a type of watermark to be embedded in the image based on the first copy protection parameter;
- embedding the selected type of watermark into the image in the portable device;
- and
- transmitting the watermarked image through an interface of the portable device.

A method comprising:
- accessing an unwatermarked version of an image in a portable device;
- determining that the unwatermarked version of the image is about to be distributed;
- in response to determining that the unwatermarked version of the image is about to be distributed:
- determining whether a watermarked version of the image is stored in the portable device;
- in response to determining a watermarked version of the image is stored in the portable device, replacing the unwatermarked version of the image with the watermarked version of the image, the quality of the watermarked version of the image being automatically modified based on a desired level of copy protection for the image, where an amount of image modification is based on the desired level of copy protection for the image;
- and
- distributing the watermarked version of the image through an interface of the portable device.

A device comprising:
- an interface;
- and
- a processor to:
- access an image in the device;
- receive a first copy protection parameter for the image;
- receive a second copy protection parameter for the image;
- in response to determining the second copy protection parameter conflicts with the first copy protection parameter, reject the second copy protection parameter;
- determine that the image is about to be transmitted;
- in response to determining that the image is about to be transmitted:
- determine whether a watermarked version of the image is stored in the portable device;
- in response to determining a watermarked version of the image is not stored in the portable device, automatically select a type of watermark to be embedded in the image based on the first copy protection parameter;
- and
- automatically embed the selected type of watermark into the image;
- and
- initiate transmission of the image with the watermark through the interface to another device.

A portable device comprising:
- an interface;
- and
- a processor to:
- access a first unwatermarked version of an image in the portable device;
- determine that the first unwatermarked version of the image is about to be sent;
- in response to determining that the first unwatermarked version of the image is about to be sent:
- replace the first unwatermarked version of the image with a second unwatermarked version of the image
- automatically reduce a quality of the second unwatermarked version of the image based on a desired level of copy protection for the image, where an amount of image quality reduction is based on the desired level of copy protection for the image;
- and
- initiate sending of the image with the reduced quality to another device by using the interface.

A wireless device comprising:
- means for accessing an image in the wireless device;
- means for receiving a first copy protection parameter for the image;
- means for receiving a second copy protection parameter for the image;
- in response to determining the second copy protection parameter conflicts with the first copy protection parameter, means for rejecting the second copy protection parameter;
- means for determining that the image is about to be transferred;
- in response to determining that the image is about to be transferred:
- means for determining whether a watermarked version of the image is stored in the portable device;
- in response to determining a watermarked version of the image is not stored in the portable device, means for automatically selecting a type of watermark to be embedded in the image based on the first copy protection parameter;
- means for embedding the selected watermark into the image;
- and
- means for transferring the image with the watermark to another wireless device.
