Surveillance server, method of processing data of surveillance server, and surveillance system
First Claim
Patent Images
1. A method for protecting image within devices that share a content key, the method comprising:
- receiving, by a server, image data from a camera, the image data being encrypted with the content key;
determining whether the image data is valid;
when the image data is determined to be valid, transmitting, by a decryption controller, the image data to a protected device as encrypted without decrypting the image data, the protected device having the content key; and
when the image data is required to be transmitted to an unprotected device, decrypting, by the decryption controller, the image data with the content key and transmitting the decrypted image data to the unprotected device not having the content key.

Abstract
A surveillance server connected to a camera through a network is provided, the camera acquiring an image of a surveillance area. The surveillance server includes: a data acquisition unit configured to acquire from the camera image data of the image that is encrypted; a mode selection unit configured to select a processing mode of the image data; and a decryption control unit configured to decrypt the image data in response to selection of a first mode.

9. A server comprising:
-
a memory configured to store a content key; a communication unit configured to receive image data in a form of encrypted data from a camera, and selectively transmit the image data to a protected device having the content key, and an unprotected device not having the content key; and a processor configured to; determine whether the image data is valid; when the image data is determined to be valid, transmit, through the communication unit, the image data to the protected device as encrypted without decrypting the image data; and when the image data is required to be transmitted to the unprotected device, decrypt the image data with the content key and transmit the decrypted image data to the unprotected device. - View Dependent Claims (10, 11, 12)

13. A camera comprising:
-
an image sensor configured to capture an image; a storage configured to store a content key and an authentication key;
a communication unit configured to communicate with a server; anda processor configured to; control the image sensor to capture the image; generate image data by encrypting the image with the content key; generate authentication data based on the authentication key to ensure validity of the image data; and transmit the image data and the authentication data to the server, wherein, at the camera, the image data is transmitted as encrypted to a protected interface comprising the server and having the content key; and wherein, at the camera, the image data is decrypted and transmitted to an unprotected device not having the content key. - View Dependent Claims (14, 15)
