Encryption is widely used to ensure security in public networks like the internet. Any type of data has its own attribute; therefore, various algorithms should be used to protect confidential data from unauthorized access. Mostly the available encryption algorithms are used for text data. However, due to large data size and real time constrains, algorithms that are good for textual data. In this research, a block-based encryption model is proposed for information security using a combination of logical and mathematical operation. This model will be used as a pre-encryption technique to confuse the relationship between the original data and the generated ones.
