Abstract
Security issues and data confidentiality are very important in the digital and internet era today. Important files circulating on the internet, both in the form of documents, images, and videos need to be supported with good security. This article aims to secure files by utilizing steganography technology, both in encryption and decryption of the file. The method used is the Advanced Encryption Standard (AES) which is applied to Stego-Object. Experiments are done on document files with extensions .doc, .xlsx, .pdf, and .txt, also on image files with extensions .jpeg, .png, and .bitmap. The experimental results show that AES can encrypt and decrypt quite effectively without changing the quality of files both images and documents. This research can develop for video files.
