System and method for operating a computing device in a secure mode

摘要

A computing device operates in a secure operating mode in response to user selection. Computer hardware is initialized to verify a bootloader of an operating system, and the bootloader verifies the operating system kernel. The kernel then verifies operating-system level executable files. After verification, a limited set of the verified files is loaded into a portion of the memory that is subsequently marked by the kernel as read-only. These files are executed to provide a basic Internet browser session; all other files are identified as non-executable. When the user accesses an authorized website and conducts a transaction that requires a user to provide information, the information is encrypted during transmission of the network. In addition, such information cannot be accessed by other parties since the information provided is not persisted at the computing device.

主权项

1. A method of providing a secure operating mode of a computing device, the method comprising:
receiving, by one or more processors, information indicating a selection of the secure operating mode; after receiving the information, verifying, by the one or more processors, an operating-system level executable file; executing, by the one or more processors, the verified operating-system level executable file in read-only memory order to conduct a transaction in the secure operating mode; during the conducting of the transaction, receiving, by the one or more processors, information input to the computing device; marking, by the one or more processors, the received information input into the computing device as non-executable; and temporarily storing, by the one or more processors, the marked information in volatile memory of the computing device.
