Abstract

In the context of a distributed database, data is stored on various computers that are interconnected through communication media such as high-speed buses or telephone lines. A distributed database system consists of a set of sites, where each site has the ability to execute transactions that access data at one or more sites. A distributed database is a collection of logical data that is physically dispersed in a computer network, which is independent of current or future application programs. Fragmentation is a phenomenon in which storage space is inefficiently utilized, resulting in reduced storage capacity, while the term also refers to the condition of the deserted storage itself. Replication, on the other hand, is a technique for copying and distributing data and database objects from one database to another, as well as maintaining data consistency through synchronization between databases.

Abstract

The Internet, an interconnected network, has become one of the most widespread data communications medias in the world. With the development of various illegal information retrieval techniques, many people try to get information that does not belong to them. Various techniques to protect sensitive information from unauthorized persons are widely used to protect important information. Steganography is a technique for hiding message files from the public who know their existence. This technique is often used to avoid suspicion or people who want to know the contents of the message file. Steganography is the science and technique of writing hidden messages so that no one else knows about their existence. Therefore, the application of plain-text steganography is inserted into the Least Significant Bit (LSB) encrypted image carrier. This allows mobile users to send the author's message to the recipient securely..
