Concepts inLimiting privacy breaches in privacy preserving data mining
Data mining
Data mining (the analysis step of the "Knowledge Discovery in Databases" process, or KDD), a relatively young and interdisciplinary field of computer science, is the process that results in the discovery of new patterns in large data sets. It utilizes methods at the intersection of artificial intelligence, machine learning, statistics, and database systems.

Privacy
Privacy (from Latin: privatus "separated from the rest, deprived of something, esp. office, participation in the government", from privo "to deprive") is the ability of an individual or group to seclude themselves or information about themselves and thereby reveal themselves selectively. The boundaries and content of what is considered private differ among cultures and individuals, but share basic common themes.

Randomization
Randomization is the process of making something random; this means: Generating a random permutation of a sequence (such as when shuffling cards). Selecting a random sample of a population. Generating random numbers: see Random number generation. Transforming a data stream (such as when using a scrambler in telecommunications).

Association rule learning
In data mining, association rule learning is a popular and well researched method for discovering interesting relations between variables in large databases. Piatetsky-Shapiro describes analyzing and presenting strong rules discovered in databases using different measures of interestingness. Based on the concept of strong rules, Agrawal et al.

Individual
An individual is a person or a specific object. Individuality is the state or quality of being an individual; a person separate from other persons and possessing his or her own needs or goals. Being self expressive, independent. From the 15th century and earlier, and also today within the fields of statistics and metaphysics, individual meant "indivisible", typically describing any numerically singular thing, but sometimes meaning "a person. " (q.v. "The problem of proper names").

Value (personal and cultural)
A personal or cultural value is an absolute or relative ethical value, the assumption of which can be the basis for ethical action. A value system is a set of consistent values and measures. A principle value is a foundation upon which other values and measures of integrity are based. Those values which are not physiologically determined and normally considered objective, such as a desire to avoid physical pain, seek pleasure, etc.

Pseudorandom generator
In theoretical computer science and cryptography, a pseudorandom generator (PRG) for a class of statistical tests is a deterministic procedure that maps a random seed to a longer pseudorandom string such that no statistical test in the class can distinguish between the output of the generator and the uniform distribution. The random seed is typically a short binary string drawn from the uniform distribution.
