Abstract

Digital images that are private and confidential are very vulnerable to eavesdropping by irresponsible parties. Especially when distributed over the internet, such as chat-based applications such as Facebook, WhatsApp and e-mail media. Image sent via the internet. Because digital images are still recognizable images and can be used by eavesdroppers for personal gain, to the detriment of those who have access to image data. The act of tapping the image data can be minimized by the application of cryptographic encryption techniques. This research will secure digital images with 128 bit AES method for encryption and decryption of digital images in client-server based applications. The results of the AES algorithm encryption produce a cipherimage with pixel values that are much different from the plainimage pixel values.

Abstract

Creating satisfaction with the library is certainly not easy, librarians must be able to provide quality services, both directly and indirectly to students, good service can certainly be of more value than librarians to students. less friendly in serving users who need information. For this reason, a Decision Support System that applies Fuzzy Associate Memory was developed to determine the level of satisfaction of library services at STMIK Triguna Dharma. In general, Decision Support Systems are computer-based information systems, including knowledge-based systems that can be used in making decisions in organizations or companies. The level of user satisfaction makes it easy for STMIK Triguna Dharma in evaluating the extent to which the quality they provide in the library is related to data on library facilities, services, and convenience. is quite satisfying.
