Cloud and data dissemination scheme for Vehicular cloud (VC) is a part of cloud computing to vehicles that participate in vehicular ad hoc networks, with the goal of providing computing and storage services to vehicles at a minimal price, trying to improve traffic safety and efficiency, it guarantees real-time services.
Because of the highly dynamic nature of VC, it is difficult to efficiently form a securely VC network and to securely deliver messages to the VC without potentially invading cloud users’ privacy.
The proposed work provides a concrete secure and privacy-preserving communication scheme for VC formation and data dissemination.
The proposed scheme enables a group of vehicles in close proximity to form a vehicular cloud with security authentication and dynamically.

Proposed system is a secure and privacy-preserving communication scheme for VC establishment and data dissemination in VC.
Specifically, this scheme allows a group of vehicles located close to each other in the VANET to form a VC securely, anonymously and dynamically.
This allows the vehicles’ resources to be integrated and shared anonymously and securely, using pseudonyms and dynamic identity based authenticated asymmetric group key agreement
In the scheme, the public key of a vehicle is its (one-time use) pseudonym. Thus, no certificate is required to bind the public key with the vehicle, and this simplifies certificate management.
The private key corresponding to the pseudonym is generated by a trusted authority based on the pseudonym of the vehicle. Using the pseudonym and the corresponding private key, each vehicle in the group can anonymously run the security protocol to form a secure VC in one round
Cloud users to send encrypted messages to the VC, and an eavesdropper is not able to learn the exchanged messages and the identities of the participants.
Privacy and Security of proposed system is ensured.

A novel steganography algorithm is proposed based on local reference edge detection technique and exclusive disjunction (XOR) property is proposed. Human eyes are less sensitive towards intensity changes in the sharp edge region compared to the uniform region of the image. Because of this, the secret message bits have been embedded in the sharp regions by local reference pixels that are located in the edge blocks. The predefined sets of pixels are easily identified with less computational complexity in the stego image. The embedding algorithm improved in terms of security and capacity using bit plane dependent XOR coding technique that makes least possible alterations in LSB bits of edge pixels. The existing edge-based steganography techniques provide better imperceptibility but relatively limits the embedding capacity. The proposed method efficiently improves the embedding capacity with an acceptable range of imperceptibility and robustness.
