Abstract

An information processing device (10) includes a first acquisition unit (110) that acquires first biological data which is biological feature data of a collated object and attribute information relating to the first biological data, a collation unit (120) that refers to a collation data storage unit (210) that stores a plurality of pieces of second biological data which are biological feature data for use in collating the first biological data, and collates the first biological data with each piece of the second biological data, a second acquisition unit (130) that acquires attribute information for each piece of the second biological data from an attribute information storage unit (220) that stores attribute information associated with each piece of the second biological data, and a specification unit (140) that compares the attribute information acquired together with the first biological data with the attribute information associated with each piece of the second biological data, and specifies at least one of the pieces of second biological data corresponding to the first biological data, on the basis of a result of the comparison and a result of the collation.

Claims

1. An information processing device comprising:

a first acquisition unit that acquires first biological data which is biological feature data of a collated object and attribute information relating to the first biological data;

a collation unit that refers to a collation data storage unit that stores a plurality of pieces of second biological data which are biological feature data for use in collating the first biological data, and collates the first biological data with each piece of the second biological data;

a second acquisition unit that acquires attribute information for each piece of the second biological data from an attribute information storage unit that stores attribute information associated with each piece of the second biological data; and

a specification unit that compares the attribute information acquired together with the first biological data with the attribute information associated with each piece of the second biological data, and specifies at least one of the pieces of second biological data corresponding to the first biological data, on the basis of a result of the comparison and a result of the collation.

2. The information processing device according to claim 1, wherein the specification unit specifies at least one of the pieces of second biological data corresponding to the first biological data by weighting the result of the collation using the result of the comparison.

3. The information processing device according to claim 1, wherein when the plurality of pieces of second biological data corresponding to the first biological data are specified, the specification unit further determines priorities of the specified pieces of second biological data, on the basis of the result of the comparison and the result of the collation.

4. The information processing device according to claim 1, further comprising an accumulation unit that accumulates the attribute information to be acquired together with the first biological data, as attribute information associated with the specified pieces of second biological data, in the attribute information storage unit.

5. The information processing device according to claim 1, wherein a priority is set for each type of the attribute information, and

the specification unit specifies at least one of the pieces of second biological data corresponding to the first biological data, on the basis of a comparison result for each type of the attribute information of the first biological data and the second biological data, a priority for each type of the attribute information, and the result of the collation.

6. The information processing device according to claim 1, wherein a plurality of the collation data storage units are present in accordance with a section of the attribute information, and

the device further comprises a selection unit that selects the collation data storage unit to be referred to during the collation from the plurality of collation data storage units, on the basis of the attribute information acquired together with the first biological data.

7. The information processing device according to claim 6, further comprising an arrangement unit that moves or copies the second biological data stored in one of the collation data storage units, to another collation data storage unit corresponding to attribute information associated with the second biological data.

8. An authentication system comprising:

an information processing device; and

a server,

wherein the information processing device includes

a first acquisition unit that acquires first biological data which is biological feature data of a collated object and attribute information relating to the first biological data, and

a transmission unit that transmits the first feature data and the attribute information, and

the server includes

a receiving unit that receives the first feature data and the attribute information,

a collation unit that refers to a collation data storage unit that stores a plurality of pieces of second biological data which are biological feature data for use in collating the first biological data, and collates the first biological data with each piece of the second biological data,

a second acquisition unit that acquires attribute information for each piece of the second biological data from an attribute information storage unit that stores attribute information associated with each piece of the second biological data, and

a specification unit that compares the attribute information acquired together with the first biological data with the attribute information associated with each piece of the second biological data, and specifies at least one of the pieces of second biological data corresponding to the first biological data, on the basis of a result of the comparison and a result of the collation.

9. An authentication method comprising causing a computer to:

acquire first biological data which is biological feature data of a collated object and attribute information relating to the first biological data;

refer to a collation data storage unit that stores a plurality of pieces of second biological data which are biological feature data for use in collating the first biological data, and collate the first biological data with each piece of the second biological data;

acquire attribute information for each piece of the second biological data from an attribute information storage unit that stores attribute information associated with each piece of the second biological data; and

compare the attribute information acquired together with the first biological data with the attribute information associated with each piece of the second biological data, and specify at least one of the pieces of second biological data corresponding to the first biological data, on the basis of a result of the comparison and a result of the collation.

10. The authentication method according to claim 9, further comprising causing the computer to specify at least one of the pieces of second biological data corresponding to the first biological data by weighting the result of the collation using the result of the comparison.

11. The authentication method according to claim 9, further comprising causing the computer to, when a plurality of pieces of the second biological data corresponding to the first biological data are specified, determine priorities of the specified pieces of second biological data on the basis of the result of the comparison and the result of the collation.

12. The authentication method according to claim 9, further comprising causing the computer to accumulate the attribute information to be acquired together with the first biological data, as attribute information associated with the specified pieces of second biological data, in the attribute information storage unit.

13. The authentication method according to claim 9, wherein a priority is set for each type of the attribute information, and

the method further comprises causing the computer to specify at least one of the pieces of second biological data corresponding to the first biological data, on the basis of a comparison result for each type of the attribute information of the first biological data and the second biological data, a priority for each type of the attribute information, and the result of the collation.
