Abstract

Claims (32)

1. A method comprising:

receiving a video stream of image frames in a video format, wherein the video stream is received from an endpoint device and comprises keystroke and/or mouse data indicative of user interactions with content displayed on a user interface of the endpoint device;

decoding image frames of the video stream from the video format;

for each respective frame of the image frames, upon completion of decoding of the respective frame, asynchronously encoding the respective frame into a lossless compression format, wherein the asynchronously encoding includes encoding a plurality of the respective frames simultaneously into the lossless compression format; and

asynchronously streaming all of the respective frames as encoded into the lossless compression format as a resulting video stream for display to a video display device.

2. The method of claim 1 , wherein the video format comprises full-frame contents of a first image frame of the video stream in its entirety, and for all subsequent frames of the video stream, only those areas of the subsequent image frames that have changed from a previous image frame of the video stream.

3. The method of claim 1 , wherein the lossless compression format comprises Portable Network Graphics (PNG) format.

4. The method of claim 1 , further comprising:

detecting suspicious user behavior in the user interactions; and

notifying a security analyst of the suspicious behavior.

5. A system comprising:

a processor; and

a non-transitory, computer-readable storage medium comprising instructions executable by the processor for:

receiving a video stream of image frames in a video format, wherein the video stream is received from an endpoint device and comprises keystroke and/or mouse data indicative of user interactions with content displayed on a user interface of the endpoint device;

decoding image frames of the video stream from the video format;

for each respective frame of the image frames, upon completion of decoding of the respective frame, asynchronously encoding the respective frame into a lossless compression format, wherein the asynchronously encoding includes encoding a plurality of the respective frames simultaneously into the lossless compression format; and

asynchronously streaming all of the respective frames as encoded into the lossless compression format as a resulting video stream for display to a video display device.

6. The system of claim 5 , wherein the video format comprises full-frame contents of a first image frame of the video stream in its entirety, and for all subsequent frames of the video stream, only those areas of the subsequent image frames that have changed from a previous image frame of the video stream.

7. The system of claim 5 , wherein the lossless compression format comprises Portable Network Graphics (PNG) format.

8. The system of claim 5 , wherein the instructions are further executable for:

detecting suspicious user behavior in the user interactions; and

notifying a security analyst of the suspicious behavior.

9. A non-transitory, computer-readable storage medium embodying computer executable instructions configured for:

receiving a video stream of image frames in a video format, wherein the video stream is received from an endpoint device and comprises keystroke and/or mouse data indicative of user interactions with content displayed on a user interface of the endpoint device;

decoding image frames of the video stream from the video format;

for each respective frame of the image frames, upon completion of decoding of the respective frame, asynchronously encoding the respective frame into a lossless compression format, wherein the asynchronously encoding includes encoding a plurality of the respective frames simultaneously into the lossless compression format; and

asynchronously streaming all of the respective frames as encoded into the lossless compression format as a resulting video stream for display to a video display device.

10. The storage medium of claim 9 , wherein the video format comprises full-frame contents of a first image frame of the video stream in its entirety, and for all subsequent frames of the video stream, only those areas of the subsequent image frames that have changed from a previous image frame of the video stream.

11. The storage medium of claim 9 , wherein the lossless compression format comprises Portable Network Graphics (PNG) format.

12. The storage medium of claim 9 , wherein the computer-executable instructions are further configured for:

detecting suspicious user behavior in the user interactions; and

notifying a security analyst of the suspicious behavior.
