Hello mate
Explanation:
1. Kaleidoscope effect
The kaleidoscope was invented by Sir David Brewster about 1816 and patented in 1817. The kaleidoscope illustrates the image-forming properties of combined, inclined mirrors. If an object is placed between two mirrors inclined at right angles, an image is formed in each mirror.
2. Mosaic effect
Mosaic effect means a situation in which information in an individual dataset, in isolation, may not pose a risk of identifying an individual, but when combined with other avail- able information could pose such a risk.
