CARDLESS ATM “You are the Cash card” ABSTRACT: Over the past three decades‚ consumers have been largely depending on and trust the Automatic Teller Machine (ATM) to conveniently meet their banking needs. However‚ despite the numerous advantages of ATM system‚ ATM fraud has recently become more widespread. In this paper‚ we provide an overview of the possible fraudulent activities that may be perpetrated against ATMs and investigates recommended approaches to prevent these types of frauds

Combinatorics -studies the way in which discrete structures can be combined or arranged. Enumerative combinatorics concentrates on counting the number of certain combinatorial objects - e.g. the twelvefold way provides a unified framework for counting permutations‚ combinations and partitions. Analytic combinatorics concerns the enumeration (i.e.‚ determining the number) of combinatorial structures using tools from complex analysis and probability theory. In contrast with enumerative combinatorics which

the cipher text. How it works In a columnar transposition‚ the message is written out in rows of a fixed length‚ and then read out again column by column‚ and the columns are chosen in some scrambled order. Both the length of the rows and the permutation of the columns are usually defined by a keyword. * Uses a two dimensional array * Text is placed in rows * Columns are transposed * Columns are read out as ciphered text What advantages and disadvantages does it have Columnar

BUTTERFLY NETWORK Butterfly network is a network with 2q nodes and q + 1 columns as an unfolded q-cube in order to facilitate the discussion‚ visualization‚ and analysis of hypercube routing algorithms. However‚ a butterfly network can be viewed as a parallel processing architecture in its own right. A butterfly architecture (Fig. A‚ left) has p = 2 q(q + 1) processors of maximum degree d = 4‚ a diameter of 2q = ∪(log p)‚ and a bisection width of ( – 1)2 q+1 + 0(2 q) = ∪(p/log p). A wrapped
