Abstract

An image security method and display method of a portable terminal are provided. The image security method includes photographing an image through a camera, storing the image, and storing Subscriber Identity Module (SIM) information of the portable terminal in EXchangeable Image File (EXIF) information of the image. The image display play method includes executing an image view, comparing Subscriber Identity Module (SIM) information of the portable terminal with SIM information within EXchangeable Image File (EXIF) information of an image stored in the portable terminal, and displaying an image depending on the comparison result.

Claims

1. An image security method of a portable terminal, the method comprising:

photographing an image through a camera;

storing the image; and

storing Subscriber Identity Module (SIM) information of the portable terminal in EXchangeable Image File (EXIF) information of the image.

2. The method of claim 1, wherein the SIM information comprises inherent information for distinguishing from a different SIM, and comprises at least one of an International Mobile Subscriber Identification (IMSI), an Integrated Circuit Card IDentification (ICCID), and SIM Serial Number (SSN) Digits.

3. The method of claim 2, wherein the portable terminal comprises a dual mode portable terminal, and the SIM information comprises information on a master SIM enabled in the portable terminal.

4. The method of claim 1, wherein the storing of the image comprises storing a time when the photographing and storing of the image occurs, in a Joint Photographic Experts Group (JPEG) form.

5. The method of claim 1, wherein the storing of the image comprises compressing the image and storing the compressed image.

6. An image display method of a portable terminal, the method comprising:

executing an image view;

comparing Subscriber Identity Module (SIM) information of the portable terminal with SIM information within EXchangeable Image File (EXIF) information of an image stored in the portable terminal; and

displaying an image depending on the comparison result.

7. The method of claim 6, wherein the SIM information comprises inherent information for distinguishing from a different SIM, and comprises at least one of an International Mobile Subscriber Identification (IMSI), an Integrated Circuit Card IDentification (ICCID), and SIM Serial Number (SSN) Digits.

8. The method of claim 7, wherein the portable terminal comprises a dual mode portable terminal, and the SIM information of the portable terminal comprises information on a master SIM enabled in the dual mode portable terminal.

9. The method of claim 8, wherein the displaying of the image comprises at least one of, if the comparison result is that the SIM information of the portable terminal is substantially the same as the SIM information of the EXIF information of the image stored in the portable terminal, displaying the image as it is and, if the comparison result is that they are not substantially the same, displaying a secured image.

10. The method of claim 6, further comprising:

securing the image stored in the portable terminal.

11. The method of claim 9, wherein the securing of the image comprises making the image at least one of mosaic and indistinct to make the image unclear.

12. The method of claim 9, further comprising:

if SIM information within an EXIF of a secured and displayed image is substantially the same as information on a slave SIM of the portable terminal, switching the slave SIM and a master SIM after activation of the slave SIM.

13. The method of claim 6, wherein the displaying of the image depending on the comparison result comprises, if the SIM information of the portable terminal is different from SIM information within EXchangeable Image File (EXIF) information of an image, not displaying any image.

14. A computer-readable recording medium having recorded thereon a program for a portable terminal, the computer-readable recording medium comprising:

a first code segment, for executing an image view;

a second code segment, for comparing Subscriber Identity Module (SIM) information of a portable terminal with SIM information within EXchangeable Image File (EXIF) information of an image stored in the portable terminal; and

a third code segment, for at least one of, if the comparison result is that the SIM information of the portable terminal is substantially the same as the SIM information of the EXIF information of the image stored in the portable terminal, displaying the image as it is and, if the comparison result is that they are not substantially the same, displaying a secured image.
