Privacy-preserving computational geometry

Privacy-preserving computational geometry is the research area on the intersection of the domains of secure multi-party computation (SMC) and computational geometry. Classical problems of computational geometry reconsidered from the point of view of SMC include shape intersection, private point inclusion problem, range searching, convex hull, and more. A pioneering work in this area was a 2001 paper by Atallah and Du, in which the secure point in polygon inclusion and polygonal intersection problems were considered. Other problems are computation of the distance between two private points and secure two-party point-circle inclusion problem. (Wikipedia).

Steganography Tutorial - Hide Messages In Images

Steganography is the hiding of a secret message within an ordinary message and the extraction of it at its destination. Steganography takes cryptography a step further by hiding an encrypted message so that no one suspects it exists. Ideally, anyone scanning your data will fail to know it
