Method and system for unlocking device having touchscreen monitor

A method of receiving and checking a verification code for a device having a touch screen, the method comprising the steps of:

• a client of the device obtaining a pattern of the verification code from a network side;
• the client of the device monitoring an input of the touch screen;
• if the monitored input of the touch screen is matched with the pattern of the verification code, the client of the device allowing a user to log in;
• and
• the client of the device obtaining updates of the pattern of the verification code from the network side at each re-login.

A system for unlocking a device having a touch screen, comprising a communication module, a parsing module, a trace point management module, a touch screen input checking module, and an execution module,

• the communication module is configured to communicate with an external network through the device and receive updates of a pattern of a logo;
• the parsing module is configured to communicate with the communication module and the trace point management module, receive the pattern of the logo from the communication module, parse the pattern of the logo, and obtain a contour and a shape of the pattern;
• the trace point management module is configured to communicate with the parsing module, obtain a boundary and a shape, and create trace points based on the shape;
• the touch screen input checking module is configured to communicate with the trace point management module and hardware of the device, and compare a position of an input on the touch careen with positions of the trace points;
• and
• the execution module is configured to communicate with the touch screen input checking module and output corresponding operation instructions based on a result of the checking.
