The high increase in the transmission of digital data over secured and unsecured communications channels poses a lot of security and privacy concerns to both the transmitter and the receiver. Many operations engaged today in urban and warfare, be they for construction, monitory of plants, high voltage lines, military, police, fire service and intelligence etc. engages the use of surveillance systems that transmit sensitive data to and fro the command centre to the remote areas and this data in transmission needs to be secured. In this paper, the authors proposed a hybrid cryptographic and digital watermarking technique for securing digital images based on a generated symmetric key.
