Abstract

A method and apparatus are provided for remotely controlling access to pornographic content of an image in a first device, the method including acquiring content of the image, determining whether the content of the image is pornographic by analyzing at least one image frame constituting the contents of the image, blocking access to the content of the image when the content is determined to be pornographic, extracting at least one representative problematic image frame from the content of the image; transmitting the at least one representative problematic image frame to a second device; receiving control commands from the second device and controlling access to the content of the image blocked in the first device, based on the control commands.

Claims

1. A method of remotely controlling access to pornographic content of an image in a first device, the method comprising:

acquiring content of at least one image;

determining whether the content of the at least one image is pornographic by analyzing at least one image frame constituting the content of the image;

blocking access to the content of the at least one image when the content is determined to be pornographic;

copying at least one representative problematic image frame from the content of the image;

transmitting the at least one representative problematic image frame to a second device;

receiving control commands from the second device; and

controlling access to the content of the image blocked in the first device, based on the control commands.

2. The method of claim 1, wherein blocking of the use of the content of the image comprises encrypting the content of the image, or inactivating the content of the image based on a file system of the first device.

3. The method of claim 2, wherein receiving of the control commands from the second device comprises receiving a decryption key or an activation key permitting access to the blocked content of the image.

4. The method of claim 3, wherein controlling access to the content of the image comprises performing at least one controlling operation from among playback, storing, copying, moving, deleting and editing, on the content of the image.

5. The method of claim 4, wherein controlling access to the content of the image further comprises controlling the content of the image according to a degree of controlling when the contents of the image are used, including entire allowance, partial allowance or entire disallowance.

6. The method of claim 5, wherein controlling access to the content of the image further comprises controlling the content of the image based on a point of time when the content of the image is capable of being used, a length and a duration of the content of the image, an amount of the content of the image, a quality of the content of the image, and a medium for transmitting the content of the image.

7. The method of claim 3, wherein the copied representative problematic image frame is an image having a relatively high degree of lewdness among the problematic images that exceeds a predetermined reference value, and

wherein the degree of lewdness is determined according to the ratio of skin estimation areas that is estimated to be human skin, based on color values of pixels of the at least one problematic image frame.

8. The method of claim 1, wherein transmitting of the at least one representative problematic image frame to the second device is performed using a multimedia message service (MMS) or a mobile e-mail via which a message with the representative problematic image frame is attached.

9. The method of claim 1, wherein receiving of the control commands from the second device comprises mutually authenticating whether the second device that transmits the control commands is an authenticated device registered with the first device.

10. The method of claim 1, further comprising:

storing the at least one extracted representative problematic image frame; and

allowing an authorized user to retrieve the stored representative problematic image frame.

11. An apparatus for remotely controlling access to pornographic content of an image in a first device, the apparatus comprising:

an image content acquiring unit by which the first device receives the content of the image from;

a pornography determining unit which determines whether the content of the image is pornographic by analyzing a plurality of image frames constituting the content of the image;

a pornography processing unit which blocks access to the content of the image when the content is determined to be pornographic;

a pornography sample acquiring unit which copies at least one representative problematic image frame from the content of the image; and

a network interface unit which transmits the at least one representative problematic image frame to a second device, and which receives control commands from the second device,

wherein the pornography processing unit controls access to the content of the image blocked in the first device, based on the control commands.

12. The apparatus of claim 11, wherein the pornography processing unit encrypts the content of the image, or, based on a file system of the first device, inactivates the content of the image.

13. The apparatus of claim 12, wherein the network interface unit comprises a control key receiving unit for receiving a decryption key or an activation key of the blocked content of the image.

14. The apparatus of claim 13, wherein the pornography processing unit performs at least one controlling operation from among playback, storing, copying, moving, deleting and editing on the content of the image.

15. The apparatus of claim 14, wherein the pornography processing unit controls access to the content of the image according to a degree of controlling when the contents of the image are used, including entire allowance, partial allowance or entire disallowance.

16. The apparatus of claim 15, wherein the pornography processing unit controls access to the content of the image, based on a point of time when the content of the image are capable of being used, a length and a duration of the content of the image, an amount of the content of the image, a quality of the content of the image, and a medium for transmitting the content of the image.

17. The apparatus of claim 11, wherein the extracted representative problematic image frame is an image having a relatively high degree of lewdness among problematic images that exceeds a predetermined reference value, and

wherein the degree of lewdness is determined according to the ratio of skin estimation areas that is estimated to be human skin, based on color values of pixels of the at least one image frame.

18. The apparatus of claim 11, wherein the network interface unit uses a multimedia message service (MMS) or a mobile e-mail to transmit a message with the representative problematic image frame attached.

19. The apparatus of claim 11, wherein the network interface unit comprises an authentication unit for mutually authenticating whether the second device that transmits the control commands is an authenticated device registered with the first device.

20. The apparatus of claim 11, further comprising:

an image storage unit in which the at least one extracted representative problematic image frame is stored; and

an image inquiry unit which allows an authorized user to retrieve the stored representative problematic image frame.

21. A computer program product for remotely controlling access to pornographic content of an image, the computer program product embodied on a computer readable recording medium and when executed by a computer, performs a method comprising:

acquiring content of at least one image;

determining whether the content of the at least one image is pornographic by analyzing at least one image frame constituting the content of the image;

blocking access to the content of the at least one image when the content is determined to be pornographic;

copying at least one representative problematic image frame from the content of the image;

transmitting the at least one representative problematic image frame to a second device;

receiving control commands from the second device; and

controlling access to the content of the image blocked in the first device, based on the control commands.

22. A method for remote blocking of content of an image, the method comprising:

identifying inappropriate content in an image on a first device;

transmitting a portion of the inappropriate content to a second device;

receiving commands from the second device indicating whether the inappropriate content may be displayed on the first device.
