“…In recent years, selfdestructing or disappearing texts have gained traction and become more accessible to many users. The size and sensitivity of data transferred across the Internet continue to grow, emphasizing the increasing importance of network security [8]. The Data Encryption Standard (DES) encryption technique has its origins in the LUCIFER Feistel block cipher, developed in 1971 by IBM cryptography expert Horst Feistel [9].…”

It is possible to encode a message using one of the encryption algorithms and embed the text within a selected frame from the video, as this is considered a more secure method for handling confidential information. The concealment is deemed unbreakable because the message is encrypted in a manner that prevents decryption, making it challenging to retrieve the hidden text. In this study, Data Encryption Standard (DES) technology was employed to embed the last bits of the chosen video frame using a software-based approach. The frames, decoders, PSNR, and encrypted messages are illustrated in various videos. The results demonstrated minimal impact on the video's accuracy, as concealment occurs in the least significant bits (LSB), preserving the overall precision of the video.
