Performance analysis of compression algorithms for information security: A Review [PDF]

open access: yesEAI Endorsed Transactions on Scalable Information Systems, 2020
Data compression is a vital part of information security, since compressed data is much more secure and convenient tohandle. Effective data compression technique creates an effective, secure, easy communicable & redundant data.
