Web17 sep. 2024 · Background: Data that are in the form of text, audio, image, and video are used everywhere in our modern scientific world. These data are stored in physical storage, cloud storage and other storage devices. Some of these data are very sensitive and require efficient security while storing as well as in transmitting from the sender to the receiver. … Web5 aug. 2024 · Huffman coding is lossless data compression algorithm. In this algorithm a variable-length code is assigned to input different characters. The code length is related with how frequently characters are used. Most frequent characters have smallest codes, and longer codes for least frequent characters. There are mainly two parts.
