Abstract
Techniques from the proposed invention relate to providing enhanced security. For example, techniques described herein allow a computer system, such as a mobile device, to support a wide variety of security functions and security sensitive applications on a mobile device by providing enhanced security via secure input and output data transmission and verification through a secure module. The secure module may cause user interfaces to be provided to users by providing obfuscated user interface data to the operating system that do not reveal elements that are part of the user interfaces. The secure module may receive obfuscated user input values representing user input values, and de-obfuscate these user input values, whereby the actual input values are not exposed to the underlying operating system. The secure module may track the flow of user input/output data through the computing device to ensure the integrity and authenticity of this data.
