The present paper proposed a novel approach called Wavelet based Least Significant Bit Watermarking (WLSBWM) for high authentication, security and copyright protection. Alphabet Pattern (AP) approach is used to generate shuffled image in the first stage and Pell's Cat Map (PCM) is used for providing more security and strong protection from attacks. PCM applied on each 5×5 sub images. A wavelet concept is used to reduce the dimensionality of the image until it equals to the size of the watermark image. Discrete Cosign Transform is applied in the first stage; later N level Discrete Wavelet Transform (DWT) is applied for reducing up to the size of the watermark image. The water mark image is inserted in LH n Sub band of the wavelet image using LSB concept. Simulation results show that the proposed technique produces better PSNR and similarity measure. The experimental results indicate that the present approach is more reliable and secure efficient. The robustness of the proposed scheme is evaluated against various image-processing attacks.

The “unprecedented growth” in the field of technology has gone past leaps and bounds to such an extent that it has given birth to a “life saving technique” to reveal the images of hidden objects that might prove to be an ecstatic news for the pilots to prevent flight crashes due to blurred weather and enabling the surgeons to perform a bloodless surgery. An effective way to accomplish this is to recover the image behind the obstacle by varying the electrical voltage across a crystal of Non-Linear material such as BBO, LBO. The image absorbs the energy from noise and showcases its structure to the observers as voltage is optimally varied. For weak signals, such as distant or dark images, incorporating noise into them can enhance their quality. It’s high time that we look into this technique in a futuristic perspective and implement it in a rampant manner to “prevent the exorbitant death toll and thereby save the invaluable lives of human beings existing in the universe.”

The pivotal role of lithium batteries in energy storage is a well known fact. But in today’s fast paced revolutionary world, problems like charge retaining difficulty, excess heat generation, leakage etc make them impossible devices for energy storage. Instead of going in for the conventional lithium batteries, a new battery can be brought into existence which uses the body fluid (blood) as its electrolyte. Inside the mystic human system, during the oxidation process of the carbohydrates we consume, electrons are liberated which may be used to power up a tiny battery inside, the rate of which is controlled by the nanobots. As multifunctionality is the need of the hour, numerous tiny sensors placed inside our body which operate on MEMS technique not only monitors the body tissues but also detects any block in arteries and veins, cancer causing cells and gives suitable command to the nanobots. The rate at which the nanobots clear the imperfection can be made faster by swarm intelligence. The multifunctionality aspect of nanobots is further enhanced as they act as an effective substitute for dialyser and pacemaker.

An automatic checkout system (ACOS) designed and developed for a surface-to-air ,missilẽ stem is d~scribed. The system has a built-in self-check and has been extensively used for checking faults in the subsystems of ground electronics. It has resulted in saving a lot of effort in quickly diagnosing and rectifying f~ults. ThJ salient features of the ACOS have been described and the scope
