“…According to the format of the image data to be protected, a number of important of component, including pixels (samples), bit-planes, line, blocks, macro-blocks, slices, transform coefficients and tree nodes, can be permuted. In last two decades, a number of permutation techniques were proposed to address the image security in digital data communication [4,5].The secrecy of keys and the familiarity of the keys are only given to the authorized users of the systems enhance the entire security of the cryptographic system. The security of image implemented through the key generation from an image will be stored in the database is more advanced cryptography method.…”

 Abstract: The advancements in internet and 5G communication technologies enormously use images as a crucial element for effective digital communication. Most of the digital devices support image communication as a prominent way of communication in digital Era. Most of the unauthorized access of digital Era communications leads to serious issues in digital data or digital image communications. Hence, Image Security in digital communication becomes an egress area of research in Digital Era. This paper is to design and implement an algorithm with a 96 bits cryptographic system. The result analysis carries out in this paper on input images and presents the comparative analysis of our proposed algorithm with the standard algorithmsthrough standard performance evaluation metrics. then following two keys, each of 16-bits, are generated. Key 1 (16-bit) -0 0 1 1 1 0 0 1 0 1 0 0 0 0 1 1 Key 2 (16 -bit) -0 0 1 0 0 1 0 0 0 0 0 1 0 0 1 1 And when encryption is done by using 64-bit symmetric SF key then following four keys, each of 16-bits, are generated. Key 1 (16-bit) -0 0 0 0 0 0 0 0 0 0 1 1 0 0 0 0 Key 2 (16 -bit) -0 0 0 0 0 0 1 1 1 0 0 0 0 1 1 1 Key 3 (16-bit) -0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Key 4 (16 -bit) -1 1 1 0 0 1 0 1 0 0 1 0 1 0 0 1 Finally when encryption is done by using 96-bit symmetric SF key then following six keys, each of 16-bits, are generated. Key 1 (16-bit) -0 0 0 0 0 0 0 0 0 0 1 1 0 0 0 0 Key 2 (16 -bit) -0 0 0 0 0 0 1 1 1 0 0 0 0 1 1 1 Key 3 (16-bit) -0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Key 4 (16 -bit) -1 1 1 0 0 1 0 1 0 0 1 0 1 0 0 1 Key 5 (16 -bit)-0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Key 6 (16 -bit) -1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 The performance analysis for different parameter to be performs on various images like Lena, Baboon and Under Water image. Table II indicates that 32-bits, 64-bits and 96-bits encryption. It is finding that the 96-bits encryption algorithm based on secure force is better than other encryption algorithm. Figure 3 shows the histogram analysis of original image and encrypted image using 32-bit key, 64-bit key and 96-bit key based on secure force algorithm. Figure 4 shows horizontal, vertical and diagonal correlation between original image and encrypted Lena image using 32-bit key, 64-bit key and 96-bit key based on secure force algorithm. A. AnalysisThe results obtained from experiments confirmed that the proposed 96-bit secure force algorithm performs better than other algorithms [20][21][22][23][24][25][26][27][28] in terms of NPCR and UACI. From the comparison charts shown in Table III based on NPCR and UACI, we conclude that our proposed algorithm is almost better than existing algorithms.

This study utilized a wireless transceiver module (NRF24L01) and ATmega328 to implement a cost-effective household door intercom. The intercom consist of two units; the outdoor and indoor. The outdoor unit was used by the guest to communicate with the household owner to notify them of their presence at the door while the indoor unit was used to respond to the call. The transceiver module transmits and receives audio signals between the two units, while ATmega328 handles the conversion of the signal from analog to digital during transmission and vice-versa at reception. The outcome of the test and analysis carried out on the developed prototype shows that it is user-friendly, consumes less power, and also proves that it is a cost-effective solution that can be affordable and made to be readily available to the consumer.
