. Therefore, a large number of network servers are required to store them. The Bloom filter was proposed by Barton bloom in 1970. It is actually a very long binary vector and a series of random ing functions. The preceding example shows how the job works. Assuming that we store 0.1 billion email addresses, we first create a 1.6 billion binary (bit) vector, that is, a 0.2 billion-byte vector, and then set all the 1.6 billion binary bits to zero. For each email address X, we use eight differen

the same problem.The Bron filter was proposed by Barton Bron in 1970. It is actually a very long binary vector and a series of random mapping functions. We use the above example to illustrate how it works.Assuming we store 100 million e-mail addresses, we first set up a 1,600,000,002 binary (bit), or 200 million-byte vector, and then all of the 1.6 billion binary zeros. For each e-mail address X, we use eight different random number generator (F1,F2, ..., F8) to generate eight information finge
