Abstract: Provided is a device for preventing information leakage including: a storage unit that stores message time, request source information, and request destination information in relation to each information requesting message; a unit that suspends a response message containing personal information in response messages in response to the information requesting messages, for a predetermined suspended time from a message time of the corresponding information requesting message; a unit that counts the number of information requesting messages transmitted from the same request source to the same destination and corresponding to the suspended response message on the basis of information stored in the storage unit; and a unit that, in the case where the counted number of the information requesting messages exceeds a predetermined threshold value, applies a protection process to the suspended response message so that the personal information contained in the suspended response message is not received by the request sour

Abstract: For an apparatus determining whether or not an HDD is started by barometric pressure information or the like, there are provided a navigation apparatus, an operation control device, an operation control method, and an operation control program, that enable shortening of a time from a power-on to starting-up of the HDD. The present application is the operation control device which controls the operation of the HDD by giving an instruction to the HDD to control the operation of the HDD, the operation control device including: a recording means for recording a previous closing information indicative of whether or not the operation of the operation control device normally ends by a previous power-off and an operation control means for giving an instruction of starting the operation to the HDD in a case where the operation has been normally ended at a time of starting the operation control device by the power-on.
