Abstract

A processing device receives input representing a selection of a first area of a source image. The processing device sends a request to a server machine for a result image that corresponds to the source image. The processing device, responsive to determining that the server machine does not have the result image, creates a blurred area for the first area, the blurred area corresponding to a portion of the image that contains the first area. The portion of the image having a size that is greater than an aggregate size of the first area and less than the size of the image. The processing device also sends the blurred area to the server machine for storage of the blurred area as the result image. The processing device replaces the first area with the corresponding portion of the blurred area without blurring a remaining area of the image.

receiving a selection of the data to be blurred in the dashboard image.

9. The method of claim 1, wherein creating the blurred area comprises:

transforming the first selected area in the source image into transparent areas in a foreground layer; and

superimposing the source image with the transparent areas on top of the result image, wherein the result image is in a background layer.

10. The method of claim 1, wherein creating the blurred area comprises:

transforming the result image to include a transparent area, the transparent area excluding one or more portions of the result image that correspond to the first selected area in the source image; and

superimposing the transformed result image on top of the source image.

11. The method of claim 1, further comprising:

creating an edited image, the edited image comprising the first selected area replaced with the corresponding portion in the result image; and

sharing the edited image, wherein the edited image conceals data to be protected.

12. The method of claim 1, further comprising:

receiving a request to blur a different selected area of the source image, wherein the different selected area comprises a sub-area that is not included in the first selected area; and

replacing the different selected area of the image with a second corresponding portion of the result image.

13. The method of claim 1, further comprising, responsive to determining that the server machine does have the result image, receiving the result image from the server machine to utilize in replacing the first area.

14. A system comprising:

a memory to store a source image; and

a processor coupled with the memory to;

receive input representing a selection of a first area of the source image;

send a request to a server machine for a result image that corresponds to the source image;

responsive to determining that the server machine does not have the result image;

create a blurred area for the first area, the blurred area corresponding to a portion of the image that contains the first area, the portion of the image having a size that is greater than an aggregate size of the first area and less than the size of the image; and

send the blurred area to the server machine for storage of the blurred area as the result image; and

replace the first area with the corresponding portion of the blurred area without blurring a remaining area of the image.

15. The system of claim 14, wherein the blurred area is created by:

determining that the first selected area comprise a plurality of separate sub-areas; and

performing a single blur operation to create the result image corresponding to the plurality of separate sub-areas, wherein performing the single blur operation to create the result image minimizes a number of blur operations being performed relative to applying a same blur filter to the plurality of separate sub-areas.

16. The system of claim 14, wherein the first selected area of the source image comprises data to be protected, the data being derived from a data store.

17. The system of claim 14, wherein the blurred area is accessible by one or more other processors for subsequent requests to blur at least a portion of the source image that corresponds to the blurred area.
