Ethereum Virtual Machine (EVM) defines fixed-size data types for integers. This implies that the range of numbers that an integer variable can represent is finite.For instance, a “uint8” (unsigned ...

In Solidity, integers are represented using a fixed number of bits. For example, uint8 uses 8 bits and can store values from 0 to 255. When an integer is incremented beyond its maximum value or ...

Data types are something that programmers either take the time to specify or not, depending on the programming language they code in. Data types are important for key arithmetic operations, but have a ...

Abstract: A reversible data hiding technique with high capacity of data embedding is presented in this paper. Using both difference expansion and histogram shifting methods at the same time we have ...

Abstract: Recently, a modified data hiding scheme based on pixel value differencing and improving exploiting modification directions is proposed by Shen and Huang. There are two major contributions in ...
