Effective information retrieval system in hospital is a web app which can be used in hospitals to upload patient details. Using this web app upload patient details for first time and generate a user ID for the particular patient for center use also. This user ID can be used by the patient for later use in any hospital which are linked by this web app. The proposed web app can reduce the time for the patients and the hospital workers for center use. Also, this web app can be used in any hospitals if the patient had a user ID. In this web app we provide security using Advanced Encrypted Standard algorithm. Our major goal is to link many hospitals in a single web app and to provide the details similarly. The proposed web app provides user ID for the patients and it is easier to break anywhere
