Abstract :
Self healing is a system that is implemented in a database that aims for
database security systems. This system runs on the Linux operating system and is
a service so it won't overload the server. The way this system works is that the
system will automatically create a local database and will compare the hash value
between the local database and the database server. If there is a data change, the
hash value will automatically change and the system will detect changes and the
system will automatically return the data that changes. originally in a fast and
accurate time. The test was carried out using three networks, namely peer to peer,
LAN, and internet with data changes from 10 data, 20 data, 30 data, 40 data, 50
data, 60 data, 70 data, 80 data, 90 data, and 100 data in total data of 725671
data. The trial results are seen from the size of the data and hash value before
there is a change and after the data return process there is no damage to the data,
while viewed from the speed of the process obtained the average speed using peer
to peer network 13.0976 seconds, LAN 13.5517 seconds, and internet 32.4127
seconds.
