IMG‐forensics: Multimedia‐enabled information hiding investigation using convolutional neural network

Abstract

Information hiding aims to embed a crucial amount of confidential data records into the multimedia, such as text, audio, static and dynamic image, and video. Image-based information hiding has been a significantly important topic for digital forensics. Here, active image deep steganographic approaches have come forward for hiding data. The least significant bit (LSB) steganography approach is proposed to conceal a secret message into the original image. First, the lightweight stream encryption cryptography encrypts secret information in the cover image to protect embedded information from source to destination. Whereas the encrypted embedded cover information into the carrier of stego-image with the help of the LSB and then transmit. In the proposed investigational scheme, a convolutional neural net is used. A model is trained to detect and extract patterns of image hidden features, encrypted stego-image optimization, and classify original and cover images of steganography. Through the experiment result on the forensic image database for mobile steganography of the Center for Statistics and Application in Forensic Evidence, the overall embedded and extracting that the proposed scheme can achieve information hiding as well as revealing with an accuracy rate of 95.1%. The experimental result shows the robustness of the model in terms of efficiency as compared to other state-of-the-art schemes.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Educational Blockchain: A Secure Degree Attestation and Verification Traceability Architecture for Higher Education Commission

“…The primary objective of using blockchain is to protect critical data organizations of data to gratify the particular kind of data that will be preserved on the digital ledger using the blockchain technology along with the process of storage, such as off-chain and on-chain data preservation storage [44]. In the higher education degree attestation, the overall data is more sensitive and confidential; therefore, the data must be preserved and checked against and investigate the hashes of on-chain.…”

“…The HEC regulatory authority plays an important role to manage the standards of degree attestation and verification including the secrecy of candidate certificate credentials and authenticity, checking system quality and maintainability, safety, data protectability, sensibility, resource effectiveness, transfer and exchange records between the universities and federal education authorities. These regulatory authorities look after the complete mechanism of retrieval, preserve, share, transfer, store, and exchange degree, attestation, and verification related data records, and more crucial to provide transparency, scalability, cross-chaining, and security [43,44]. In this way, the degree traceability limitations and issues can be solved with more efficiency, and they can be reorganized to deliver a better educational solution for HEC.…”

Blockchain Hyperledger with Non-Linear Machine Learning: A Novel and Secure Educational Accreditation Registration and Distributed Ledger Preservation Architecture

“…As the HED survey reported, over one-fourth of submitted applications admit that there is no pre-verified work done by the university before submitting them to HED for attestation and verification. Every year, more than 150,000 forged certificates are issued [10,11]. These misrepresented applications outperform their peers in the market for seeking jobs in highly competitive environments.…”

EPS-Ledger: Blockchain Hyperledger Sawtooth-Enabled Distributed Power Systems Chain of Operation and Control Node Privacy and Security

“…The trade of the energy and power grid system shifted from the centralized to the distributed smart power grid system; the development of the current distributed energy business model has encountered critical bottlenecks and implementation challenges [7]. The current multimedia-enabled decentralized cloud management of energy business models is highly relying on third-party services [8]. Thus, this will cause a single point of failure; moreover, it will lead to increased operating costs, potential risk and low node transaction transparency, and a high possibility of data forgery and tampering.…”
