Living body detection method, system and non-transitory computer-readable recording medium

A system for living body detection, comprising:

• a processor;
• and
• a storage;
• wherein a computer program instruction is stored in the storage, and the computer program instruction is used to perform a living body detection method when being ran by the processor, wherein the living body detection method comprises:
• acquiring device information of a terminal, wherein the terminal is used to acquire an image of an object to be detected,
• determining a device risk level of the terminal by utilizing the device information of the terminal, and
• determining a living body detection strategy based on the device risk level of the terminal,
• wherein the device information comprises information on an abnormal accessing number of the terminal, and the determining a device risk level of the terminal by utilizing the device information of the terminal when the computer program instruction being ran by the processor comprises:
• determining that the device risk level of the terminal is a high risk level if the abnormal accessing number of the terminal is greater than a first threshold;
• determining that the device risk level of the terminal is a risk level if the abnormal accessing number of the terminal is not greater than the first threshold but greater than a second threshold,
• wherein the determining a living body detection strategy based on the device risk level of the terminal when the computer program instruction being ran by the processor comprises:
• determining that the living body detecting strategy is to randomly combine increasing the number of actions required to be performed by the object to be detected and raising the difficulty of actions required to be performed by the object to be detected if the device risk level of the terminal is a risk level;
• determining that the living body detecting strategy is to randomly combine decreasing the number of actions required to be performed by the object to be detected and decreasing the difficulty of actions required to be performed by the object to be detected if the device risk level of the terminal is neither a high risk level nor a risk level.
