US Patent 9898739 System and method for ensuring safety of online transactions

Online transaction security is improved by detecting a start of an online financial transaction between a user-controlled online transaction application and a remote payment service. A protected data input module, a protected environment module, and a safe data transfer module each provides a corresponding set of protection operations. A risk level of conducting the financial transaction is assessed based on a vulnerability assessment and on present condition of the local computing system. An initial degree of protection for each of the modules is set, and subsequently adjusted based on the risk level.
