Abstract
A detection device includes processing circuitry configured to acquire position information and a file size of a falsification detection target file, and determine a change in the position information or the file size acquired, and detect falsification of the falsification detection target file in a case where there is a change in the position information or the file size.
Claims6
A detection device comprising:
- processing circuitry configured to:
- acquire position information and a file size of a falsification detection target file;
- and
- determine a change in the position information or the file size acquired, and detect falsification of the falsification detection target file in a case where there is a change in the position information or the file size.
A detection method executed by a detection device comprising:
- acquiring position information and a file size of a falsification detection target file;
- and
- determining a change in the position information or the file size acquired, and detecting falsification of the falsification detection target file in a case where there is a change in the position information or the file size.
A non-transitory computer-readable recording medium storing therein a detection program that causes a computer to execute a process comprising:
- acquiring position information and a file size of a falsification detection target file;
- and
- determining a change in the position information or the file size acquired, and detecting falsification of the falsification detection target file in a case where there is a change in the position information or the file size.
