  2. Visual cryptography - Wikipedia

    en.wikipedia.org/wiki/Visual_cryptography

    Visual cryptography is a cryptographic technique which allows visual information (pictures, text, etc.) to be encrypted in such a way that the decrypted information appears as a visual image. One of the best-known techniques has been credited to Moni Naor and Adi Shamir , who developed it in 1994. [ 1 ]

    Secret sharing was invented independently by Adi Shamir [1] and George Blakley [2] in 1979. A demonstration of visual cryptography: when two same-sized binary images of apparently random black-and-white pixels are superimposed, the Wikipedia logo appears

    visual cryptography development: Image title: Creation of masks to let overlaying n transparencies A, B,… printed with black rectangles reveal a secret image by CMG Lee. n = 4 requires 16 (2⁴) sets of codes each with 8 (2⁴⁻¹) subpixels, which can be laid out as 3×3 with the extra bit always black.

  7. Verifiable secret sharing - Wikipedia

    en.wikipedia.org/wiki/Verifiable_secret_sharing

    In cryptography, a secret sharing scheme is verifiable if auxiliary information is included that allows players to verify their shares as consistent. More formally, verifiable secret sharing ensures that even if the dealer is malicious there is a well-defined secret that the players can later reconstruct.

  8. Secret sharing using the Chinese remainder theorem - Wikipedia

    en.wikipedia.org/wiki/Secret_Sharing_using_the...

    There are several types of secret sharing schemes. The most basic types are the so-called threshold schemes, where only the cardinality of the set of shares matters. In other words, given a secret S, and n shares, any set of t shares is a set with the smallest cardinality from which the secret can be recovered, in the sense that any set of t − 1 shares is not enough to give S.
