At present mobile phone is an essential thing in our day to day life. People use mobile phones to send messages, to take photos and share them, etc. Now smart phones are highly used for several purposes such as taking photo, sending photo as message, sending voice message, etc. there are several mobile applications which are providing facilities for image sharing/transferring. Most of these applications provide end to end encryption/decryption. Some images contain very sensitive information. Therefore, security is very important in image transferring. This paper presents a method to maintain user-level security in image transferring. In mobile applications, different kinds of encryption methods are used to implement user-level security. But in this application, text-based image encryption is proposed. RGBA values and ASCII values of the text are used. Also, the Random seed matrix is used to improve encryption and the seed number will be depending on the text we used to encrypt. We used bitwise operators in this work. By using this application users can transfer images safely and decide encryption method and key themselves. [1]
