The invention provides an excitation updating method accessing to a virtual interactive platform. The method comprises the steps that triggering of a user behavior in the virtual interactive platform is intercepted so that behavior data and the state of a virtual object on which the user behavior is located are obtained; excitation numerical calculation is performed on the behavior data according to the trusted attribute and the user attribute of the virtual object, wherein the state of the virtual object on which the user behavior corresponding to the behavior data is located is the execution starting state; and numerical updating in user personal information is performed according to the excitation numerical value obtained by calculation. Besides, the invention also provides an excitation updating system accessing to the virtual interactive platform According to the excitation updating method accessing to the virtual interactive platform and the excitation updating system thereof, delay time of excitation updating can be shortened and the accuracy and the security of updating can be guaranteed.
