Abstract: The widespread use of mobile devices, especially in Indonesia where 67% of the population owns a mobile device, underscores the rapid advancement of mobile technology. Google's Android, with its open-source nature and extensive application support, has become the leading choice. In the context of increasing reliance on public services, including those provided by notaries and land deed officials, data security is of paramount importance. The development of a mobile notary application addresses this need, offering ease of interaction and reliable data security. This research implements the AES 256 encryption and decryption method, ensuring secure data exchange through the app. The AES algorithm, recognized as a Federal Information Processing Standard, secures data stored in an encrypted MySQL database. This Android-based notary app successfully uses AES-256 in document encryption, making files unreadable to unauthorized parties. The app also aims to build trust between users and notaries while preventing potential misuse of documents. Further development is expected to increase interaction between users and notaries, improving efficiency and accessibility of public services.
