A Dual-Image Based Secured Reversible Data Hiding Scheme Exploiting Weighted Matrix and Cellular Automata

In the era of advanced communication technology, security of confidential data during transmission through public media is an important issue. To curtail the risk of attacks, a secured, reversible, robust data concealing scheme with good visual quality and embedding capacity is essential while improving execution efficacy. In this context, a Cellular Automata based reversible and secured data hiding scheme using weighted matrix has been applied on dual-image which provides a trade-off between embedding capacity and visual quality. Since, the proposed scheme is robust enough against various venomous attacks, this approach is useful for private and public sectors practitioners to protect important multimedia secret information from adversarial cyber attacks.
