In this paper, a multiuser medical image encryption algorithm is proposed. The proposed utilizes polar decomposition, which enables features in the algorithm. A computer-generated hologram (CGH) improves security of gyrator domain. phase-only CGH-based offers advantages such as storing large amount information compact space, resistance to counterfeiting, and enhanced security. method validated with various statistical metrics, entropy, mean squared error, correlation coefficient, histogram,...
Abstract Fuzzy rough entropy established in the notion of fuzzy set theory, which has been effectively and efficiently applied for feature selection to handle uncertainty real-valued datasets. Further, mutual information presented by integrating with measure importance features. However, none methods till date can noise, vagueness simultaneously due both judgement identification, lead degrade overall performances learning algorithms increment number mixed valued conditional In current study,...
Abstract In this paper, a new multiuser optical image encryption and authentication technique is proposed. Sparse multiplexing polar decomposition are used in the Fresnel domain to obtain ciphertext of an input image. To enable platform, multiple private keys obtained through during process. It will allow authorized users access secure information simultaneously without having key distribution problem among them. The proposed method has large space robust against several attacks, such as...
This paper presents a new scheme for encryption of single-channel colour images. The uses amplitude- and phase-truncation approach to introduce non-linearity enhanced security. Further, the image is performed in fractional Hartley domain, which relatively less investigated. starts with an affine transform each channel input image. Thereafter, one channels considered as amplitude while other two are used phase masks, spatial frequency domain. A detailed analysis scheme's sensitivity various...
In this paper, a new asymmetric method is presented to encrypt and compress color images using discrete cosine transform in Fresnel domain. First, the input image decomposed into three channels: red, green blue. Each channel converted phase bonded with an amplitude mask followed by get complex intermediate image. Phase reservation (PR) truncation (PT) operation are performed on Thereafter, random part serves as of first private key for decryption. The propagated second PR PT operation. serve...
A new scheme for image encryption is proposed, using fractional Hartley transform followed by Arnold and singular value decomposition in the frequency domain. As plaintext an amplitude image, mask used spatial domain a random phase (RPM). The proposed has been validated grayscale images sensitive to parameters such as order of orders transform. We have also evaluated scheme's resistance well-known noise occlusions attacks.
A study has been done on axisymmetric magnetohydrodynamic (MHD) flow of a viscous incompressible outer velocity fluid along stretching cylinder. The momentum and heat partial differential equations are mold using similarity transformations into set nonlinear ordinary equations. These have solved with the help Runge-Kutta Fehlberg scheme numerically shooting technique. It is found that solution not unique for cylindrical surface. dual exists certain range parameters stability analysis shown...
