An image forming apparatus is disclosed, the image forming apparatus including a storing unit that stores a program in accordance with which the image forming apparatus operates, an acquiring unit that acquires an update program from an external source, and an updating unit. Before updating the program stored in the storing unit, the updating unit determines whether the update program acquired by the acquiring unit is authentic by checking the electronic signature of the update unit. If the updating unit determines that the update program acquired by the acquiring unit is authentic, the updating unit updates the program stored in the storing unit. Accordingly, the image forming apparatus can improve the reliability of the update program.

Image forming apparauts that checks authenticity of an update program

An information processing apparatus starts a program from a recording medium while maintaining security of a program recorded on the recording medium. A detector detects a recording medium. A recording-medium starting section activates the recording medium detected by the detector to be in an accessible state. A program starting section performs an authentication check on the recording medium, reads a program from the recording medium when a result of the authentication check is normal, and starts an execution of the program.

Information processing apparatus started from a program recorded on a recording medium with well-maintained security, and a recording medium storing such a program and a producing method of such a recording medium
