Security on the computer becomes an important issue in this era of
technology. Many of the cyber crimes we have heard from the mass media
threaten system security. The criminals use the existing security space to enter
and manipulate it. The purpose of this research is to make the application of
system security in Resort Traffic Police Unit of Banyumas using AES
cryptography. AES-based cryptographic document and image security is
developed using visual studio app with C# programming language and MySQL
database server. The data processing uses SQL syntax. From the analysis and
observations which have been done, it can be seen that the Appliction
Cryptography AES (Advance Encryption Standard) to Security Documents and
Images with is one of effective alternative for data security. So hopefully it will be
able to secure important data in secret so it will not be easy to be accessed by
Unauthorized parties, fast in coding and accurate by not reducing the value of the
information itself.
