An Image Encryption and Authentication Scheme
2011 Seventh International Conference on Computational Intelligence and Security, 2011In this paper, a fast image encryption and authentication scheme is presented. In the proposed scheme, a 512-bit message authentication code generated by a keyed hash function is embedded into the image by reversible data embedding technique. Then the embedded image is masked by the pseudo random sequence in feedback mode.

New approach to image encryption
Journal of Electronic Imaging, 1998A new cryptographic method for encrypting still images is proposed. This method is designed on the basis of the base- switching lossless image compression algorithm. The method there- fore simultaneously possesses both image encryption and lossless compression abilities. A given image is first partitioned into nonover- lapping fixed-size subimages, and

Efficient selective image encryption
Multimedia Tools and Applications, 2015Selective image encryption has a significant importance in many applications as it offers significant savings in computations, cost, and time. Many attempts are exerted for this purpose as the traditional full image encryption/decryption algorithms may be too massive. In this paper, a new technique for selective image encryption is developed.

Temporal Ordered Image Encryption
2011 Third International Conference on Communications and Mobile Computing, 2011The existing image encryption algorithms encrypt images independently, which means the probability of an eavesdropper working out one image stays the same under the same circumstances (same bits of keys and the same algorithm, for example). However, in real-life applications such as communication systems, on one hand, sequences of images may need to be

HYPERCHAOS BASED IMAGE ENCRYPTION
International Journal of Bifurcation and Chaos, 2009Chaos based encryption may offer new quality in secure data transmission. A recently proposed Chaotic-Key Based Algorithm (CKBA) has been shown to be unavoidably susceptible to chosen/known-plaintext attacks and ciphertext-only attacks. In this paper, Hyper Chaotic-Key Based Algorithm (HCKBA) using hyper chaos is proposed to enhance the security of ...

An encrypted image editing scheme based on homomorphic encryption
2015 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2015There are lots of online image applications which provide image editor services for users. As the plain image may disclose privacy, this paper proposed an encrypted image editing scheme based on homomorphic encryption to make the service be able to process the encrypted image.

An Encryption Algorithm for ROI Images
2017According to JPEG2000 image encryption algorithm based on confusion of the wavelet coefficients cannot support region-of-interest(ROI) image coding, an encryption method for ROI images is proposed. The proposed method Generates the confusion table using Chaotic sequences, confuses the Wavelet coefficients inside each code blocks, and encrypts the sign ...

Edge detection is one of the most important topics of image processing. In the scenario of cloud computing, performing edge detection may also consider privacy protection. In this paper, we propose an edge detection and image segmentation scheme on an encrypted image with Sobel edge detector.
