In addition, Mobilebased E-Hospital Applications are made. On the server made database that contains information about the patient registration data, life history, schedule doctors And the diagnosis of the patient. . In terms of data security application is applied encryption and data decryption using Blowfish algorithm so that data delivery process that happened can be more secure.
