In this paper an overview of different Light Emitting Diode (LED) display boards is presented. The enhanced LED plugs in all the loop holes in the existing product. Global Service for Message (GSM) based LED Display Board is a model for displaying notices or messages at places that require real-time noticing, by sending messages in the form of Short Message Service (SMS) through mobile. This paper proposes an idea to develop a sign board in which the messages are continuously running, where it empowers the user to change the messages using SMS instantaneously and also desk bound device such as PC or laptop. It has a dual system in terms of changing message display. It uses dual power supply such as solar power and Alternative Current (AC) power which creates the ability to work at any situation. The new design includes a motion detector which switches off the system automatically after working hours and will switch on automatically if any motion is sensed by the motion detector after the programmed working hours. This paper is a comprehensive overview of the literature and it does not contain implementation results.Keywords

This paper proposes a video steganography algorithm based on Haar Integer Wavelet Transforms (IWT) and Least Significant Bits (LSB) substitution for data hiding and extraction in Red Green Blue (RGB) components of the video files. In this approach, the cover-video is divided into RGB frames and the text in binary form is embedded into the LSBs of IWT coefficients. The embedded text is extracted from stego-video using the reverse process of data hiding. The proposed system was implemented using Audio Video Interleave (AVI) files. The experimental results prove that the proposed system has shown imperceptible modifications in AVI videos that lead to high security and an eavesdropper's inability to detect hidden data. The proposed system is simple and therefore can be used to transfer highly confidential data like military secrets, hospital reports and other data.Keywords
