Abstract: Mechanisms for protecting an application from an untrusted operating system (OS) are provided, the methods including: determining that a virtual address for a page of memory allocated by the untrusted OS for the application belongs to a valid mapping; determining that the page of memory is not already in use; and in response to determining that the virtual address for the page of memory belongs to a valid mapping and determining that the page of memory is not already in use, mapping the page of memory to an enclaved container for the application. Some mechanisms further include unmapping the page of memory from the untrusted OS. In some mechanism, determining that the virtual address for the page of memory belongs to a valid mapping is based on a list of valid mappings for the application.

Abstract: A method and system are provided for performing an inter-process communication (IPC) transaction among multiple personas in a mobile technology platform. The method includes receiving a request for an IPC transaction from an initiating persona to transfer data to at least one receiving persona, wherein the initiating and receiving personas are part of the multiple personas; analyzing the request to identify whether the initiating persona has permissions to transfer the data to the at least one receiving persona; upon identifying that the initiating persona has permissions to transfer the data, receiving the data from the initiating persona, when the initiating persona has the required permissions; analyzing the received data to determine compatibility with the at least one receiving persona; and upon determining that the data is compatible, enabling execution of the IPC transaction, thereby allowing the transfer of data.

Abstract: A method and system for sharing programs among first and second personas on a mobile technology platform equipped with a display. The method includes providing a first software application; in response to a user's launch of the first application in either the first persona or the second persona, starting the first application in a third persona; and in response to the user's launch of the first application in either the first persona or the second persona, switching the user from a persona of origin to the third persona, wherein the persona of origin is the persona in which the user launched the first application, wherein the first and second personas are defined as a set of user preferences associated with an operating system of the mobile technology platform.

Abstract: A method and system for switching between personas on a mobile technology platform equipped with a display. The method includes rendering a selectable feature on the display while a user is in a first persona; and in response to the user's selection of the selectable feature, undertaking an action in a second persona, wherein the first and second personas are defined as set of user preferences associated with an operating system of the mobile technology platform.

Abstract: A mobile technology platform equipped with a display and a processor is provided. The platform comprises an operating system executed by the processor; and a software program configured to run on the operating system, wherein the software program is further configured to establish a plurality of personas for a user of the mobile technology platform, wherein each of the plurality of personas has a unique set of user preferences associated with a persona, each of the unique set of user preferences corresponds to a unique execution environment, wherein the software program is further configured to establish a first display portion comprising a first persona environment and a second display portion comprising a second persona environment, wherein the first and second persona execution environments do not overlap.
