An Efficient Method for Digital Image Encryption Based on Improved Chaotic Map

With the development of information technologies and the increasing possibility of unauthorized access to data published on the Internet, the need to take care of data has become an important issue. One method that can be useful in data security is encryption. By using data encryption, data can be easily distributed in different environments safely. This paper presents and investigates an encryption method based on chaos theory for digital images. The tests and analyses performed on encrypted images show that the presented method has the necessary efficiency.
