Abstract

Claims (15)

1. A mobile terminal, comprising:

a first storage to store watermark data including source information;

a camera module to obtain an image and to convert the image into analog electric image data;

an image data encoder to encode the analog electric image data into digital image data and to insert the watermark data stored in the first storage into the digital image data to generate encoded image data;

a second storage to store the encoded image data having the watermark data,

wherein the source information comprises an electronic serial number (ESN) or a phone number of the mobile terminal obtaining the image.

2. The mobile terminal as recited in claim 1 , further comprising:

an image data compressor to compress the encoded image data having the watermark data to generate compressed image data and to allow the compressed image data to be stored in the second storage.

3. A method for inserting watermark data into image data, the method comprising the steps of:

a) obtaining an image and converting the image into analog electric image data;

b) encoding the analog electric image data into digital image data and inserting watermark data into the digital image data to generate encoded image data; and

c) storing the encoded image data having the watermark data,

wherein the watermark data includes source information, the source information comprising an electronic serial number (ESN) or a phone number of a mobile terminal obtaining the image.

4. The method as recited in claim 3 , the method further comprising the step of:

d) compressing the encoded image data having the watermark data to generate compressed image data and storing the compressed image data.
