Abstract

A system and method for enabling access of content in a home network are provided. The method includes receiving a content on a source device. Further, the method includes setting content sharing preferences by the source device. The content sharing preferences indicate whether a device is authorized to access the content. The method includes encrypting the content on the source device. Further, the method includes storing the encrypted content in a shared storage device. The method includes receiving a request from a device for decryption of the encrypted content. Further, the method includes decrypting the content by the source device based on the content sharing preferences. Furthermore, the method includes providing the decrypted content to the device, thereby enabling access of the content to the device.

receiving decrypted content from the device by the target device.

7. The method of claim 6, wherein the device comprises at least one of a source device, and the shared storage device.

8. The method of claim 6,

wherein the content stored in the shared storage device is stored based on content sharing preferences, and

wherein the content sharing preferences comprises allowing access to the device connected to the home network, or restricting access to the device connected to the home network.

9. The method of claim 6, wherein the content list comprises at least one of metadata of the content including content name and date of creation, source device name, network information of the source device, name of user that stored the content in the shared storage device, and a playable status of the stored content.

10. The method of claim 9, wherein the playable status indicates one of

power status of the source device, connection status of the source device, and sharing preference of the source device,

wherein the sharing preference indicates whether the target device is allowed to view the content.

11. A method of operating a shared storage device, the method comprising:

storing an encrypted content provided by a source device;

providing content list which is generated based on the encrypted content to a target device;

receiving a request from the target device to decrypt the encrypted content;

sending the request to the source device;

receiving decrypted content from the source device; and

rendering the decrypted content to the target device.

12. The method of claim 11, wherein sending the request to the source device is performed based on content sharing preferences.

13. The method of claim 12, wherein the content sharing preferences comprises at least one of allowing access to the device connected to the home network, and restricting access to the device connected to the home network.

14. The method of claim 13, further comprising:

modifying the content sharing preferences in real time.

15. The method of claim 12, wherein the content sharing preferences is provided by the source device and is stored in one of the source device and the shared storage device.

16. The method of claim 11, wherein the content list comprises at least one of metadata of the content including but not limited to content name, time and date of creation, file format, file size, source device name, network information of the source device, name of user that stored the content in the shared storage device, and a playable status of the stored content.

17. The method of claim 16, wherein a playable status indicates one of power status of the source device;

connection status of the source device, and a sharing preference of the source device, and

wherein the sharing preference indicates whether the target device is allowed to view the content.

18. The method of claim 16, wherein the playable status is based on information retrieved from the source device, the information being one of user interest to allow decryption for a particular target device, device on/off stage, resource availability for decryption, and network connectivity details.

19. The method of claim 18, further comprising:

monitoring the playable status; and

updating the playable status in real time based on the result of the monitoring.

20. An apparatus of a source device, the apparatus comprising:

a communication interface; and

a processor operatively coupled to the communication interface,

wherein the processor is configured to;

encrypt a content received on the source device,

set content sharing preferences based on the encrypted content,

store the encrypted content in a shared storage device base on the content sharing preferences,
