Statistical zero-knowledge [13] means that the distributions are not necessarily exactly the same, but they are statistically close, meaning that their statistical difference is a negligible function. We speak of computational zero-knowledge if no efficient algorithm can distinguish the two distributions.
A common use of a zero-knowledge password proof is in authentication systems where one party wants to prove its identity to a second party using a password but doesn't want the second party or anybody else to learn anything about the password. For example, apps can validate a password without processing it and a payment app can check the ...
In addition, zero-knowledge services often strive to hold as little metadata as possible, holding only that data that is functionally needed by the service. The term "zero-knowledge" was popularized by backup service SpiderOak , which later switched to using the term "no knowledge" to avoid confusion with the computer science concept of zero ...
Non-interactive zero-knowledge proof (NIZKs) are zero-knowledge proofs that require no interaction between the prover and verifier. Differential privacy : An algorithm is constrained so that the results or outputs of a data analysis can't tell if a certain individuals' information is being used to analyze and form the results.
Zero knowledge may mean: Zero-knowledge proof , a concept from cryptography, an interactive method for one party to prove to another that a (usually mathematical) statement is true, without revealing anything other than the veracity of the statement
In colloquial use, the term "code" is often used to mean any method of encryption or concealment of meaning. However, in cryptography, code has a more specific meaning: the replacement of a unit of plaintext (i.e., a meaningful word or phrase) with a code word (for example, "wallaby" replaces "attack at dawn"). A cypher, in contrast, is a ...
Some retailers say their tools use zero-knowledge encryption (meaning that the service provider can't access the data). Others explicitly say that they use patient data to train their AIs, or rent or resell it to third parties; the nature of privacy protections used in such situations is unclear, and they are likely not to be fully effective.
"Emergency Erase" (АВАРИЙНОЕ СТИРАНИЕ) switch, zeroize in NSA parlance, on a cryptographic device of the Soviet Strategic Rocket Forces. In cryptography, zeroisation (also spelled zeroization) is the practice of erasing sensitive parameters (electronically stored data, cryptographic keys, and critical security parameters) from a cryptographic module to prevent their disclosure ...
