For Secure Data Transmission Over Internet, It Is Important To Transfer Data In High Security And High Confidentiality, Information Security Is The Most Important Issue Of Data Communication In Networks And Internet. Either Image Or Video To Secure Transferred Information From Intruders, It Is Important To Convert The Information Into Cryptic Format The Image And Video Work On The Same Process. Different Methods Used To Ensure Data Security And Confidentiality During Transmission Like Steganography And Cryptography. This Paper We Convert Plaintext To Cipher Text For Doing So We Have Used RC6 Encryption Algorithm The Proposed Algorithm Ensure The Encryption And Decryption Using RC6 Stream Cipher And RGB Pixel Shuffling With Steganography By Using Hash-least Significant Bit (HLSB) That Make Use Of Hash Function To Developed Significant Way To Insert Data Bits In LSB Bits Of RGB Pixels Of Cover Image. The Security Evaluations For The Steganography Part We Will Be Using Modified LSB Algorithm Where We Overwrite The LSB Bits Of The Selected Frame (given By The User) From The Cover Video, With The Bit Of Text Message Character With Help Of Secret Key And Using KSA And PRGA.
