1. An output control apparatus comprising:
- an output section that outputs data to outside;
a condition storage section that stores an abnormal condition showing a characteristic of an operational pattern of the output section that results when malicious software outputs data and a normal condition showing a characteristic of an operational pattern of the output section that results when software other than the malicious software outputs data; and
an output control section that controls output of data by the output section based on the likelihood that malicious software is responsible for the output by prohibiting output of data when a characteristic of an operational pattern of the output section satisfies the abnormal condition, permitting output of the data when the characteristic of the operational pattern of the output section satisfies the normal condition, and inquiring a user whether to output the data when the characteristic of the operational pattern of the output section does not satisfy either the abnormal condition or the normal condition, whereinthe output control section confirms the validity of the user'"'"'s instruction of whether to output the data, receives the user'"'"'s instruction when the validity of the user'"'"'s instruction is confirmed, and permits output of the data when the received user'"'"'s instruction is to output the data.

Abstract
Provided is an output section that outputs data to outside; a condition storage section that stores an abnormal condition showing at least one of a characteristic of data to be outputted from the output section by means of malicious software and a characteristic of an operational pattern of the output section that results when the malicious software outputs data; and an output control section that prohibits output of data when at least one of a characteristic of data to be outputted from the output section and a characteristic of an operational pattern of the output section satisfies the abnormal condition.

2. A non-transitory computer-readable medium storing therein a program that causes a computer to function as an output control apparatus comprising:
-
an output section that outputs data to outside; a condition storage section that stores an abnormal condition showing a characteristic of an operational pattern of the output section that results when malicious software outputs data and a normal condition showing a characteristic of an operational pattern of the output section that results when software other than the malicious software outputs data; and an output control section that controls output of data by the output section based on the likelihood that malicious software is responsible for the output by prohibiting output of data when a characteristic of an operational pattern of the output section satisfies the abnormal condition, permitting output of the data when the characteristic of the operational pattern of the output section satisfies the normal condition, and inquiring a user whether to output the data when the characteristic of the operational pattern of the output section does not satisfy either the abnormal condition or the normal condition, wherein the output control section confirms the validity of the user'"'"'s instruction of whether to output the data, receives the user'"'"'s instruction when the validity of the user'"'"'s instruction is confirmed, and permits output of the data when the received user'"'"'s instruction is to output the data. - View Dependent Claims (13, 14, 15, 16)

3. An output control method comprising:
-
storing, in a condition storage section, an abnormal condition showing a characteristic of an operational pattern of an output section that results when malicious software outputs data and a normal condition showing a characteristic of an operational pattern of the output section that results when software other than the malicious software outputs data; and controlling output of data based on the likelihood that malicious software is responsible for the output by; comparing, with the abnormal condition, a characteristic of an operational pattern of the output section, and when the characteristic of the operational pattern of the output section satisfies the abnormal condition, prohibiting output of the data; comparing, with the normal condition, the characteristic of the operational pattern of the output section, and when the characteristic of the operational pattern of the output section satisfies the normal condition, permitting output of the data; inquiring a user whether to output the data when the characteristic of the operational pattern of the output section does not satisfy either the abnormal condition or the normal condition; and confirming the validity of the user'"'"'s instruction, made in response to said inquiring, of whether to output the data, receiving the user'"'"'s instruction when the validity of the user'"'"'s instruction is confirmed, and permitting output of the data when the received user'"'"'s instruction is to output the data. - View Dependent Claims (6, 9, 17, 18)

4. An output control system comprising:
-
a server; and a terminal that exchanges information with the server via a communication line, wherein the terminal includes; an output section that outputs data to outside; and a characteristic information collecting section that collects characteristic information showing a characteristic of an operation of the output section, and transmits the characteristic information to the server, and the server includes; a condition storage section that stores an abnormal condition showing a characteristic of an operation of the output section that results when malicious software outputs data and a normal condition showing a characteristic of an operational pattern of the output section that results when software other than the malicious software outputs data; and a deciding section that receives the characteristic information and controls output of the data based on the likelihood that malicious software is responsible for the output by deciding to prohibit output of the data when the characteristic information satisfies the abnormal condition, deciding to permit output of the data when the characteristic information satisfies the normal condition, deciding whether to prohibit or permit output of the data on the basis of inquiring a user whether to output the data when the characteristic information does not satisfy either the abnormal condition or the normal condition, and notifying the output section of the decision, wherein the output section does not output the data to outside when having received the decision to prohibit the output of the data, and the deciding section confirms the validity of the user'"'"'s instruction of whether to output the data, receives the user'"'"'s instruction when the validity of the user'"'"'s instruction is confirmed, and permits output of the data when the received user'"'"'s instruction is to output the data. - View Dependent Claims (7, 10, 19, 20)
