In digital signal processing, the general problem of image compression involves encoding using fewer bits than the original representation. Compression can be either lossy or lossless. Image encryption is hiding image from unauthorized access with the help of secret key. Even though Compression-then-Encryption (CTE) paradigm meets the requirements in many secure transmission scenarios, the order of applying the compression and encryption needs to be reversed in situations without compromising the compression performance. In this paper we analyze various techniques emerged for Encryption then Compression process for image data security.

India is facing acute shortage of electricity especially in rural sector due to shrinking of conventional grid supply. The expansion of grid has become almost standstill due to depletion of raw material i.e., fuel, coal etc., day by day. As a result, the sustainability of power supply to rural houses has become poor. In this paper a Micro Smart Grid Model for Indian rural society has been proposed and developed to overcome such constraints. In the prototype model integration of power grid with micro grid consisting of renewable solar energy sources using 1kW intelligent bidirectional converter has been done to provide a good quality 24 x7 power supply to rural houses with grid power saving up to 50% or more. Sensitivity analysis on load profile on a prototype module has been done. Impact study on generation of self employment through vocational literacy classes among potential youth in rural society has been carried out with encouraging result.
