Claim:
1. A security system including an information processing apparatus provided with a locking mechanism, a security control apparatus arranged in a vicinity of the information processing apparatus, and a mobile terminal, and being configured to output an unlock instruction by using the mobile terminal, the security system comprising: an authentication processing unit which performs an authentication on whether the mobile terminal is permitted to output the unlock instruction; a distance determining unit which determines whether the mobile terminal comes within a predetermined distance from the information processing apparatus; and an unlocking unit which outputs an unlock instruction signal to the information processing apparatus, wherein the authentication processing unit and the unlocking unit are provided in the security control apparatus, and the distance determining unit is provided in the mobile terminal, wherein at least one of the security control apparatus and the information processing apparatus includes a wireless communication unit which performs a short-range wireless communication with a wireless communication unit of the mobile terminal, wherein the distance determining unit determines whether an electric field strength of a signal communicated between the wireless communication unit of either of the security control apparatus and the information processing apparatus and the wireless communication unit of the mobile terminal is greater than a predetermined value to determine that the mobile terminal comes within the predetermined distance from the information processing apparatus when the electric field strength is greater than the predetermined value, wherein the mobile terminal includes a notification unit which notifies that the mobile terminal comes within the predetermined distance from the information processing apparatus when the distance determining unit determines that the mobile terminal comes within the predetermined distance from the information processing apparatus, an operation unit that receives a predetermined operation in accordance with a notification by the notification unit, and an identification information transmission unit which transmits identification information, wherein the authentication processing unit compares the identification information transmitted from the mobile terminal with identification information that is previously stored in the security control apparatus, to perform the authentication, and wherein the unlocking unit outputs the unlock instruction signal to the information processing apparatus only when the predetermined operation is received by the mobile terminal and also the authentication processing unit succeeds in the authentication.
