Classification: CPC G | IPC G

Claim 0:
1. A touch-based method for user authentication, comprising:
a training stage, comprising:
generating a plurality of training touch parameters by a touch interface; and
generating a training heat map and training a neural network model according to the plurality of training touch parameters by a processor; and

an authentication stage, comprising:
generating a plurality of testing touch parameters by the touch interface;
generating a testing heat map according to the plurality of testing touch parameters by the processor;
comparing, by the processor, the testing heat map and the training heat map to generate an error map;
calculating a first error value according to the error map by the processor;
inputting, by the processor, the plurality of testing touch parameters to the neural network model to generate a predicted value; and
generating one of a pass signal and a fail signal according to the first error value and a second error value by the processor, wherein the second error value is associated with the predicted value and an actual value.
