Steganografi pada Video Digital Menggunakan Metode 2LSB
Abstract – This research represents a steganography technique using 2LSB method to insert a secret message into a video. Every 2 bits of the secret message are embedded into the RGB pixel values of the cover frames respectively. A linear congruential generator algorithm works as a steganography key to determine the order of the cover frame to be inserted secret message. The proposed method is tested based on general steganography criteria including imperceptibility, fidelity and recovery. Imperceptibility test result show 86.67% of the 30 respondents answered no change in video after inserted text message and 46.67% for image message. Testing fidelity for each video inserted message using PSNR calculation produces a value above 87dB. Testing recovery for each message after extraction using PSNR calculation produces an infinity value. Computational time is also measured and the results show the size of the secret message and the video cover affect the computational time required.
