“…Initially, a owner of content separated a real image into the ROI and the RONI, after that, it encodes the image by means of a key for encryption. Ramalingam [26] presented DWT and DCT coefficients to improve the safety of hidden data and reduces alterations to preserve enhanced quality of video. The results obtained from comparison reveals that the implemented process presents enhanced privacy and reduces interruptions for improved video quality.…”

Data anonymization is the main feature of privacy preservation, and it assists in eradicating the privacy hazard in data preparation in various applications including IoT. Pseudonymity and Anonymization are two significant security factors that were adopted when sensitive data are shared. In medical field, data is usually distributed horizontally with diverse regions carrying a similar set of characteristics for various anonymization techniques.

Steganography allows data secrecy of any form inside any cover type without getting identified by any third person. Not only hiding the data could secure the secret instead applying any security/encryption technique would ensure its full secrecy and security. This paper presents two audio data hiding scheme inside a cover video by using LSB replacement technique for steganography. The acoustic data is encrypted by using XOR method before embedding it inside LSBs of original video. The secret audio data bits are inculcated inside a random frame and also in all sequential frames of cover video. Comparison among the two embedding schemes is done in this paper. Comparative analysis among the approaches is done on the parametric grounds of steganography. The results show that the randomized embedding technique is better than the sequential embedding technique on the security grounds and require less time for embedding and extraction.

“…The question here is how to transfer secret or private data in a secure way, especially in higher education institutions. Steganography is one of the most important techniques used to secure information [4]. Steganography is the art and science of hiding secret data within seemingly innocent carriers, which can be employed to achieve covert communications [5,6].…”

“…This, in turn, results almost in no perceivable changes in the cover media [13]. The Least Significant Bit (LSB) method is the most widely used method for spatial-domain-based steganography [4,14]. This method is the simplest and bestknown way for embedding secret data [15].…”

With the advancement of technology and the methods of information storage and exchange, the security of information and data became a vital issue for many institutions, especially higher education institutions. This paper introduces a novel and efficient information security system based on steganography and compression techniques to address the issues related to the security and efficient transmission of secret data in higher education institutions. In this system, the Lempel Ziv Welch (LZW) compression technique is used to compress the data to be hidden, to reduce their size and thereby reduce the percentage of distortion that may occur to the cover image. In addition, a new data hiding algorithm has been developed depending on the second bit, where data are hidden based on LSB without making any changes to the values of the second bit. If any changes are made, these will be only within LSB, which reduces the distortion in the cover image and increases the similarity between the cover image before and after hiding. In the retrieval stage, hidden data are retrieved from the second bit only. The proposed system performance was evaluated in terms of MSE (mean square of error), PSNR (peak signal-to-noise ratio), PD (pixel distortion) and BER (bit error rate). The experimental results confirm the efficiency of the proposed system that achieves good results with higher PSNR and lower MSE.
