It is assumed that the reader possesses some background in the design and analysis of algorithms. The work comprises seven chapters plus an appendix and a comprehensive bibliography. Ch. 1 is an introduction to
4.2.2 Categories of hashing methods The methods to compute hashing functions can be roughly divided into two categories, i.e., data-independent and data-dependent. Data-independent methods usually design generalized hashing functions that can compact any given data set into binary codes. Locality-Se...
simpler structures, and thus lower computational overhead. This makes them ideal for digital implementations while retaining the core properties of chaos. A variety of 1D discrete chaotic maps have been employed in the design of hash functions39,40,41,42,43,44,45,46,...
smart analysis of how humans visually interpret agricultural images can aid in the surveillance and management of environmental challenges such as droughts, soil degradation, and flooding. In practice, the way humans direct their gaze when viewing agricultural landscapes can be represented as a pathway,...

Hash function.The central part of the hashing process is the hash function. This function takes the input data and applies a series of mathematical operations to it, resulting in a fixed-length string of characters. The hash function ensures that even a small change in the input data produces...
In spite of the fact that many of these schemes inherit the BHHO algebraic structure, there does not seem to be a general prin- ciple that explains the design or analysis of these schemes: the BHHO analysis uses an intermediate notion of an "expanded system", whereas that of Brakerski ...
of the research in the area is to design an algorithm for this problem that achieves sublinear (or even logarithmic) query time.The nearest-neighbor problem has been extensively investigated in the field of computational geometry. Unfortunately, as the dimension grows, the algorithms become less ...
While this is a highly desirable security property of cryptographic hash algorithms, digital forensic investigators are interested in a hash algorithm that can be used to compare two distinctly different items and determine their fundamental level of sim- ilarity. Context-triggered piecewise hashing, ...
Sort through all the files in Dir A: a. If the hash value of a file matches a hash value in Pool X, do nothing and go to the next file. b. If the hash value of a file doesn’t match a hash value in Pool X, copy the file to Dir B before moving to the next file. Validat...
