Data storage device and method for real-time data locking in surveillance storage
A data storage device and method for real-time data locking in surveillance storage are provided. In one embodiment, a data storage device is provided comprising a memory and a controller. The controller is configured to receive an image of an object of interest from a host; receive a video stream from the host; and as the video stream is being received from the host, determine whether the object of interest is present in the video stream. Other embodiments are provided.
1. A data storage device comprising:
a memory; and
a controller configured to:
receive an image of an object of interest from a host;
receive a video stream from the host;
as the video stream is being received from the host and prior to the video stream being stored in the memory, determine whether the object of interest is present in the video stream; and
in response to determining that the object of interest is present in the video stream:
inform the host that the object of interest is present in the video stream; and
receive, from the host, additional portions of the video stream captured with a higher resolution after the object of interest was determined to be present in the video stream.
2. The data storage device of claim 1 , wherein the controller is further configured to determine whether the object of interest is present in the video stream in real time as the video stream is being received from the host.
3. The data storage device of claim 1 , wherein the controller is further configured to determine whether the object of interest is present in the video stream by:
decoding the video stream as it is received from the host;
extracting intra-coded picture frames (I-frames) from the decoded video stream; and
determining a match percentage of the extracted I-frames and the image of the object of interest.
4. The data storage device of claim 3 , wherein the controller is further configured to determine that the object of interest is present in the video stream in response to the match percentage exceeding a threshold.
5. The data storage device of claim 3 , wherein the controller is further configured to determine the match percentage at a frequency associated with a quality of service requirement.
6. The data storage device of claim 3 , wherein the controller is further configured to store the match percentage in a data structure.
7. The data storage device of claim 1 , wherein the controller is further configured to:
in response to determining that the object of interest is present in the video stream, provide the host with an identifier of a video frame in the video stream that contains the object of interest.
8. The data storage device of claim 7 , wherein the identifier of the video frame comprises a logical block address of a location in the memory that stores the video frame.
9. The data storage device of claim 7 , wherein the identifier of the video frame comprises a time tag.
10. The data storage device of claim 7 , wherein the controller is further configured to provide the host with a match percentage of the video frame and the image of the object of interest.
11. The data storage device of claim 1 , wherein the controller is farther configured to use machine learning to determine whether the object of interest is present in the video stream.
12. The data storage device of claim 1 , wherein the memory comprises a three-dimensional memory.
13. A method comprising:
performing the following in a host in communication with a data storage device comprising a memory:
sending an image of an object of interest to the data storage device;
sending a video stream to the data storage device;
instructing the data storage device to find the object of interest in the video stream;
receiving, from the data storage device, an indication that the object of interest was found in the video stream; and
sending additional portions of the video stream captured with a hi her resolution after the indication was received.
14. The method of claim 13 , further comprising:
in response to receiving the indication, instructing a video capture device to improve resolution.
15. The method of claim 13 , further comprising:
in response to receiving the indication, sending a request to the data storage device for a video frame in the video stream that contains the object of interest.
16. The method of claim 13 , wherein the indication comprises one or more of the following: a logical block address of a location in the memory that stores the video frame, a time tag, and a match percentage of the video frame and the image of the object of interest.
17. The method of claim 13 , further comprising sending a plurality of images of objects of interest to the data storage device.
18. The method of claim 17 , further comprising prioritizing the plurality of images sent to the data storage device.
19. A data storage device comprising:
a memory;
means for receiving an image of an object of interest from a host;
means for receiving a video stream from the host;
means for determining, as the video stream is being received from the host and prior to the video stream being stored in the memory, whether the object of interest is present in the video stream;
means for informing the host that the object of interest is present in the video stream in response to determining that the object of interest is present in the video stream; and
means for receiving, from the host, additional portions of the video stream captured with a higher resolution after the object of interest was determined to be present in the video stream.
20. The method of claim 13 , wherein the indication comprises an identifier of a video frame of the video stream that contains the object of interest.
