Nowadays, the security of confidential data is the vital issue in the digital world. Information security becomes even more essential in storing and transmitting data while online. For protecting digital data and achieving security and confidentiality over an insecure internet, the iterative Bat-Genetic Encryption Technique (B-GET) is proposed. The main stages of B-GET are preprocessing, encryption process, bat algorithm steps, and genetic processes. B-GET also comprises an arithmetic and logical operators that increase encryption quality. Empirical results show that the reconstructed data is a copy of the original. It also demonstrates that B-GET technique has a large space key and several defensive stages that resist many attacks and it has strong security based on multiple steps, multiple variables, and the main stages of the B-GET technique. Encrypted data is nearly random and does not contain any indication to secret data.
