Abstract
Distributed steganography is an approach to concealing the secret in several files, leaving fewer traces than the classical approach. Recent work proposed by Moyou and Ndoumdan have improved this approach by preserving the integrity of these files in a multi-cloud storage environment. However, the approach requires a large size of the stego-key and the management of several cloud storage environments. Our contribution consists is to improve this approach by using a single cloud storage environment and reducing the size of the stego-key. In this work, a single cloud storage environment is used to solve the problems of managing several credentials, monetary costs and data controls associated with multi-cloud storage environments. The comparisons showed interesting results with simpler operations to be performed by the participants during the process.
Highlights
The protection of information has know a growing expansion over time, with the multiplicity of intrusions and thefts of information by the entities and institutions [1, 2]
The credentials of the cloud accounts used for each example are given in the Table 2
In this paper, we proposed three steganographic schemes distributed in a single cloud environment, which improves the work proposed by Moyou and Ndoundam[13] on the management of the problems of multi-cloud environments and the large size of the key used in the approach
Summary
The protection of information has know a growing expansion over time, with the multiplicity of intrusions and thefts of information by the entities and institutions [1, 2]. Since the receiver shares the same secret key with the sender, it logs to the cloud storage environment and searches the correspondence between the files in the stego-folder and the files in the different cover folders.
