One-key dialing method and device

The invention discloses a one-key dialing method and device so as to try the best to dial more numbers by one key and guarantee safety. The method comprises the following steps: identifying the finger print of a finger which is in contact with a number key, wherein the number on the number key is any one of numbers from one to nine; querying a mapping table of number key-finger print-called number, and determining the called number corresponding to the identified finger print according to a unique corresponding relation of the number key, the finger print and the called number in the mapping table of number key-finger print-called number; dialing the determined called number. Through the adoption of the technical scheme provided by the invention, on one hand, the number of phone numbers dialed by one key is greatly increased; on the other hand, as finger prints of an illegal user cannot be successfully identified, calling the fixed number set by the legal user cannot be realized by one-key dialing, so that the safety of a mobile terminal using the method and device disclosed by the invention is improved.
