Secure Mobile Text Messenger App Development
The customer is a European provider of integrated solutions and interactive systems for scalable networks, travel, trading and healthcare organizations.
Our customer needed a highly secure Android application to provide smartphone users with a tool for private text conversations.
ScienceSoft’s healthcare app developers created an Android app with a clean, intuitive interface to let users focus on their messages and contacts only. To ensure privacy, the solution uses 4096-bit RSA and 256-bit AES encryption.
When kicking off a protected texting session, the user primarily sets up a 6-digit PIN-code. From this point on, the messages inside the application are secured with a password. The user also decides which conversations are to be secured by adding particular contacts to the contact book.
The solution encrypts messages on the terminal device (end-to-end) and uses SMS protocol for message delivery. Therefore, nobody can intercept and read users’ texts. The app even encrypts its internal phone book and the message history.
ScienceSoft’s team developed a user-friendly Android app to secure text conversations thanks to advanced encryption. The delivered solution helps various types of users: businesspersons, developers, health professionals and individuals concerned about their data security.
