The Exponential Growth Of Digital Communication Has Increased The Demand For Secure And Reliable Methods Of Information Concealment. Steganography, The Science Of Hiding Information Within Digital Media, Offers An Effective Solution For Covert Communication By Embedding Secret Data Into Images And Videos Without Arousing Suspicion. This Work Proposes A Hybrid Approach That Integrates Cryptography With Steganography To Enhance Both Confidentiality And Robustness. In The Proposed System, Sensitive Text Messages Are First Encrypted Using The RC6 Block Cipher, A Symmetric Key Encryption Algorithm Known For Its Efficiency And Strong Security Against Cryptanalytic Attacks. The Encrypted Data Is Then Embedded Into Video Frames Using The Least Significant Bit (LSB) Substitution Technique, Ensuring Minimal Distortion And Imperceptibility To The Human Eye. To Further Strengthen Access Control, A Password-based Authentication Mechanism Is Incorporated To Restrict Unauthorized Extraction. Experimental Evaluation Demonstrates That The Proposed Model Achieves High Payload Capacity, Strong Resistance Against Steganalysis, And Effective Protection Of Hidden Information, Making It A Viable Solution For Secure Multimedia Communication In Modern Digital Environments.
