Engineering College, Tamil Nadu, India ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract - The project is a medical related data sharing between two parts: One part is the hospital management treated as the admin part and then patient side to be treated as the user part. The admin uploads the medical record (Data and patient ID) in a cloud platform which can then be searched using the particular patient ID. The medical document reference ID automatically converts to the QR code using QRDroid function, and then we can download the particular document. The user Registration module here includes the OTP system .The main advantages of this project is more secure transaction between two sides, more flexible, easy access , finally paper free report. In existing system, RFID technology was used, which is not suitable for more sensible data storing and it is not compatible in all sectors. Key Words: Android, Encryption, Internet, Decryption, QR Code. 1. INTRODUCTION Today is the world of android phones and their applications have now become an integral part of almost all sectors such as health, entertainment, office, college, banking etc. With the increase of android devices, many problems like privacy leakages have also increased. The user’s private i nformation can be accessed easily. In many applications, the user accepts the terms and conditions but they are unaware about that their private information can be leaked by certain applications without permission. There is an android permission system which controls the admittance of resources of the mobile device. Hence permissions can be misused deliberately so imposing permissions is not enough to prevent from permission violations. Android’s enforcement of the permissions is at the level of individual apps, allowing multiple malevolent apps to collude and combine their permissions or to trick vulnerable apps to execute actions on their behalf that are beyond their individual rights. 2. QR Code Format The structure of a QR code consists of a 2D matrix where each cell is of 1pixel area. In general, QR code consists of square black modules on a white background where the black square defines 0 in binary and the white square defines 1 in binary. In practice, the whole part of a QR code isn’t used for only storing information, rather it consists of different sections. In this section we will review the sections in a QR Code Fig -1: Schematic Diagram of QR Code 1. Finder Pattern: In QR Code finder pattern is a 3X3 matrix in 3 corners of the square except the bottom right corner. The QR finder pattern helps the decoder software to identify the correct orientation of the QR code. ʹ. Separators: Separators are used to separate the finder’s pattern from actual information. The width of separators is 1pixel and it is of complete white. 3. Format Information: The Format Information, a 15 bits section next to the separators, stores information about the error correction level of the QR Code and the chosen masking pattern. 4. Alignment Pattern: Alignment Patterns support the decoder software in compensating for moderate image distortions. 5. Timing Pattern: Timing pattern consists of the alternate black and white boxes, which allows the decoding software to recognize the width of each module. 6. Data: In data section, information, converted in bit stream is stored in 8-bit parts named code words. 7. Error Correction Section: In this section information is stored in similar manner as the data section. It, as the name suggests, is used for error corrections. 8. Remainder Section: This section consists of empty bits, if data and error correction bits cannot be divided properly into 8 bit code words. 3. PROPSED SYSTEM A QR code is created by encoding the mobile phone user’s emergency and medical information (such as the name and contact details of the user’s next of kin, their doctor or specialist, blood group, allergies, etc.). The created code
