The present invention relates to a method and apparatus for providing picture privacy in video. The method includes separating, by the processor, pixels of a first type from pixels of a second type in a current gray-scale frame based on a decision threshold, where each of the pixels of the first and second types includes an image pixel value, and applying, by the processor, a privacy filter to the pixels of the first type. The privacy filter is configured to randomly swap the image pixel values within a pixel area to occur at different locations in the pixel area. The method further includes combining, by the processor, the filter pixels of the first type with the pixels of the second type.
