In this work we aimed to Least Significant Bit (LSB) based information hiding over video files using Koblitz's Method over Elliptic Curve Cryptography. After which the message to be sent to the recipient converted into ASCII characters, single index characters are encrypted by Koblitz's Method, (x,y) pairs obtained, and it is assumed that these pairs (x,y) express as a coordinate points. The pixel value on the relevant frame of single index points replaced with next double index ASCII character's binary value using LSB method. After repeating the same process for all characters in the message, the message is hidden into the video frames.
