“…In this procedure by inserting a secret message into a file, one can then prove ownership and/or guarantee the reliability of the item. Vu et al [41] propose the multi-bit marking layer (MBML) method, which consists of reusing results from the previous embedding time (layer) as input data to continue embedding them in audio signals, the method demonstrates adequate performance in the error and signal to noise ratio (SNR) embedding rate surpassing methods such as LSB, large sample embedding (ELS), bit marking (BM) and BM/SW method (sliding window) which consist of a single layer.…”

This article presents a steganography proposal based on embedding data expressed in base 10 by directly replacing the pixel values from images red, green blue (RGB) with a novel compression technique based on watermarks. The method considers a manipulation of the object to be embedded through a data compression triple process via LZ77 and base 64, watermark from low-quality images, embedded via discrete wavelet transformation-singular value decomposition (DWT-SVD), message embedded by watermark is recovered with data loss calculated, the watermark image and lost data is compressed again using LZ77 and base 64 to generate the final message. The final message is embedded in portable network graphic (PNG) images taken from the Microsoft common objects in context (COCO), ImageNet and uncompressed color image database (UCID) datasets, through a filtering process pixel of the images, where the selected pixels expressed in base 10, and the final message data is embedded by replacing units’ position of each pixel. In experimentation results an average of 40 dB in peak signal noise to ratio (PSNR) and 0.98 in the similarity structural index metric (SSIM) evaluation were obtained, and evasion steganalysis rates of up to 93% for stego-images, the data embedded average is 3.2 bpp.

“…6 As a result, a number of enhanced CPA schemes have been developed further. Although this traditional auditing schemes [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] eliminate "certificate management and key escrow problem but users commonly permit a third-party auditor (TPA)" to verify the integrity of the outsourced data. The trustworthy TPA can also give users reliable auditing findings by reducing communication and computation costs.…”

.With the widespread of digital information and advanced internet technologies, cyber-physical systems (CPS) generate numerous data. Due to the limited storage and computing capacity, CPS devices outsource data to cloud servers. When the data is outsourced to cloud servers, users lose control of their data. Several traditional and blockchain auditing schemes were proposed to verify the integrity of the data. Unfortunately, these existing schemes suffer from key escrow problem, and they are unsuitable for CPS devices as they involve substantial computation costs. This paper proposes an efficient blockchain-based certificateless short signature public auditing scheme for cloud-based CPSs, which uses blockchain technology to verify the integrity of the data. Further, our scheme requires only one pairing operation and two hash functions in the verification process. The performance analysis demonstrates that the proposed scheme outperforms and satisfies low-bandwidth device requirements.
