ENTRY AND EXIT CONTROL APPARATUS
First Claim
1. An entry and exit control apparatus comprising:
- an entry and exit history storage unit in which entry and exit information is cumulatively stored, the entry and exit information comprising a user, a controlled area which the user enters and exits, a type of entry and exit, and entry and exit date and time being related to one another in the entry and exit information;
a staying time information storage unit in which staying time information is stored, a user staying time being statistically processed in each controlled area in the staying time information;
a traveling time information storage unit in which traveling time information is stored, a user traveling time between two controlled areas being statistically processed in the traveling time information;
a missing determination unit which determines whether or not the entry and exit information stored in the entry and exit history storage unit is missing for each user;
an estimation unit which estimates entry and exit date and time for the entry and exit information on the user that the missing determination unit determines is missing based on the staying time information on the corresponding controlled area and the traveling time information between the two corresponding controlled area, the staying time information on the corresponding controlled area being stored in the staying time information storage unit, the traveling time information between the two corresponding controlled areas being stored in the traveling time information storage unit;
a complementary entry and exit information extraction unit which extracts complementary entry and exit information from the pieces of entry and exit information stored in the entry and exit history storage unit based on the entry and exit date and time estimated by the estimation unit, the complementary entry and exit information complementing the entry and exit information on the user that the missing determination unit determines is missing; and
a complementary unit which complements the entry and exit information that the missing determination unit determines the missing item by the complementary entry and exit information extracted by the complementary entry and exit information extraction unit.

Abstract
An entry and exit control apparatus wherein missing entry and exit information on a user entering and exiting a controlled area by tailgating is complemented by entry and exit information on another user presumed to enter and exit the controlled area along with the user that is tailgating. Therefore, reliability of user entry and exit history is improved to sufficiently suppress a decrease in security in the controlled area. The entry and exit control apparatus estimates entry and exit date and time concerning the missing entry and exit information based on the statistically processed staying time information of the user and the traveling time information for the entry and exit date information of the user determined that a missing item is generated, extracts complementary entry and exit information from pieces of entry and exit information stored in an entry and exit history DB based on the estimated entry and exit date and time, and complements the missing entry and exit information on the user using the extracted complementary entry and exit information.
