Abstract
Described systems and methods allow a client system to carry out secure transactions with a remote service-providing server, in applications such as online banking and e-commerce. The server may evaluate each transaction to determine whether the transaction requires security clearance, according to criteria including, among others, a transaction amount, a location of the client system, and/or a history of transactions carried out for the respective user. In some embodiments, when the transaction requires security clearance, the server instructs the client system to switch to executing a secure virtual machine. In some embodiments, most transaction details (e.g., a selection of merchandise, an amount of a bank transfer, a delivery address) are sent to the server from a regular browser application, while a transaction authorization is sent to the server from within the secure virtual machine.
