A method for verifying signatures includes the following steps. Generate corresponding input signals in response to user's operation for inputting a signature on an electronic device. Then detect coordinates of the handwriting of the user's signature. Extract the feature of the user's signature according to the detected coordinates. Generate a user identifier according to the extracted feature of the user's signature, and transmit the extracted feature of the user's signature and the generated user identifier to a server. Retrieve the feature of signature corresponding to the user identifier recording in the storage unit. And finally, compare the retrieved feature of signature with the received feature of the user's signature transmitted from the electronic device, to verify whether they are the same; and transmit the verified result to the electronic device. An electronic device and a signature verifying system are also provided.

A computer mouse includes a housing and two wheels that are capable of rolling on a supporting surface. A first pair of light sources and a second pair of light sources are arranged at one side of the two wheels, respectively. A light sensor changes from a first state to a second state after receiving light, and changes from the second state to the first state after the light is blocked. A driving module is used for successively turning on the first pair of light sources and the second pair of light sources in a first frequency. A scanning module is used for scanning the light sensor in a second frequency, to obtain states of the light sensor. A controlling module is used for generating data representative of movement of the housing according to the states of the light sensor.
