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

AI infrastructure firm Nebius Group on Monday said it was raising $700 million in a private placement from investors including Nvidia, Accel and some accounts managed by Orbis Investments. Nebius ...
Adi Shamir (Hebrew: עדי שמיר; born July 6, 1952) is an Israeli cryptographer and inventor. He is a co-inventor of the Rivest–Shamir–Adleman (RSA) algorithm (along with Ron Rivest and Len Adleman), a co-inventor of the Feige–Fiat–Shamir identification scheme (along with Uriel Feige and Amos Fiat), one of the inventors of differential cryptanalysis and has made numerous ...
And better still, its shares seem attractively valued, with a recent forward-looking price-to-earnings (P/E) ratio of 8.7, well below the five-year average of 10.7. 2. Medtronic.

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.
