Abstract:
1. A non-transitory computer-readable storage medium having stored therein a program for causing a computer to execute a process comprising: recognizing a first individual address of each of one or more other devices located in a first environment in which the computer is located at a first point in time; mapping each first individual address to a first individual point in a coordinate space; recognizing a first distribution using coordinates of each first individual point; recognizing a second individual address of each of one or more other devices located in a second environment in which the computer is located at a second point in time; mapping each second individual address to a second individual point in the coordinate space; recognizing a second distribution using coordinates of each second individual point; judging whether the first distribution and the second distribution match in accordance with a distribution matching criterion as to whether two distributions match; outputting a first result that the first environment and the second environment are identical, when the first distribution and the second distribution are judged to match; and outputting a second result that the first environment and the second environment are different, when the first distribution and the second distribution are not judged to match, wherein the process further comprising: receiving an input of first biometric information from a user; reading second biometric information which is associated with the user and stored in advance in a first storage unit, from the first storage unit; when the first result is output, judging using a first threshold whether a degree of matching between the first biometric information and the second biometric information satisfies a biometric information matching criterion.
