Mobile devices, like personal computers, run on operating systems with their own vulnerabilities and security issues. The increase in mobile device use has directed security experts to improve their mobile application security processes. Since the secure configuration of mobile devices as hardware is not commercially preferred, data must be protected with certain software on mobile devices. In software measures, runtime memory preview or key can be estimated from the information in the application. Insufficient security measures can lead to data protection, privacy violations, credit card payment standards violations, identity theft, and fraud. Procenne product, EndCrypt, generates keys with new, tailored codes and combines them with random numbers to eliminate predictability. EndCrypt plays a central role in end-to-end strong encryption and the security of mobile devices with its own private library.
