Abstract

Various systems and methods for authenticating a user are described herein. A system to includes a biometric scanner to scan an input sequence of biometric identifiers; a storage device to store a biometric identifier database; an input module to receive the input sequence of biometric identifiers; an access module to access the biometric identifier database and retrieve a secret sequence of biometric identifiers; a comparator module to compare the input sequence of biometric identifiers to the secret sequence of biometric identifiers to obtain a result; and an authorization module to, based on the result, allow access to a resource provided by the system.

Claims

1. A system for authenticating a user, the system comprising:

a biometric scanner to scan an input sequence of biometric identifiers, the input sequence including a first biometric identifier that is followed by at least one subsequent biometric identifier in a particular order;

a storage device to store a biometric identifier database;

an input circuit to receive the input sequence of biometric identifiers;

an access circuit to access the biometric identifier database and retrieve a predefined secret sequence of biometric identifiers, wherein the access circuit is to;

detect the first biometric identifier received via the biometric scanner and the input circuit; and

retrieve the secret sequence of biometric identifiers based on detection of only the first biometric identifier;

a comparator circuit to compare the input sequence of biometric identifiers to the secret sequence of biometric identifiers to obtain a result; and

an authorization circuit to, based on the result, allow access to a resource provided by the system.

2. The system of claim 1, wherein to access the biometric identifier database to retrieve the secret sequence of biometric identifiers, the access circuit is to:

calculate a hash key based on the first biometric identifier; and

use the hash key to retrieve the secret sequence of biometric identifiers in a hash table.

3. The system of claim 2, wherein the secret sequence of biometric identifiers is stored in the hash table, the hash table indexed by a checksum hash.

4. The system of claim 3, wherein the checksum hash is calculated from the first biometric identifier in the secret sequence of biometric identifiers.

5. The system of claim 4, wherein the checksum hash is calculated using an MD5 SUM technique.

6. The system of claim 3, wherein the secret sequence of biometric identifiers is stored as a sequence of biometric templates in the hash table.

7. The system of claim 2, wherein the hash table is encrypted.

8. The system of claim 1,

wherein the input circuit is to receive a request to create the secret sequence of biometric identifiers;

wherein the input circuit is to receive a plurality of biometric identifier scans obtained by the biometric scanner; and

wherein the access circuit is to;

for each biometric identifier scan in the plurality of biometric identifier scans;

initiate the creation of a biometric template of the biometric identifier scan; and

store the biometric template of the biometric identifier scan, preserving the order of the plurality of biometric identifier scans to form a sequence of biometric identifier scans.

9. The system of claim 1, wherein the resource provided by the system includes one of:

access to an online account, physical access to an area, a vehicle ignition process, elevator access, computer resource access, email access, banking account access, or credit card account access.

10. The system of claim 1, wherein the biometric identifier includes a fingerprint.

11. The system of claim 1, wherein the biometric identifier includes a retinal scan.

12. The system of claim 1, wherein the biometric identifier includes a fingerprint and a retinal scan.

13. A non-transitory machine-readable medium including instructions for authenticating a user, which when executed by a machine, cause the machine to perform operations comprising:

reading, at a biometric scanner coupled to a computing device, an input sequence of biometric identifiers, the input sequence including a first biometric identifier that is followed by at least one subsequent biometric identifier in a particular order;

accessing a biometric identifier database to retrieve a predefined secret sequence of biometric identifiers, including;

detecting the first biometric identifier received via the biometric scanner and the input circuit; and

retrieving the secret sequence of biometric identifiers based on detection of only the first biometric identifier;

comparing the input sequence of biometric identifiers to the secret sequence of biometric identifiers to obtain a result; and

based on the result, allowing access to a resource provided by the computing device.

14. The machine-readable medium of claim 13, wherein accessing the biometric identifier database to retrieve the secret sequence of biometric identifiers comprises:

calculating a hash key based on the first biometric identifier; and

using the hash key to retrieve the secret sequence of biometric identifiers in a hash table.

15. The machine-readable medium of claim 14, wherein the secret sequence of biometric identifiers is stored in the hash table, the hash table indexed by a checksum hash.

16. The machine-readable medium of claim 15, wherein the checksum hash is calculated from the first biometric identifier in the secret sequence of biometric identifiers.

17. A method for authenticating a user, the method comprising:

reading, at a biometric scanner coupled to a computing device, an input sequence of biometric identifiers, the input sequence including a first biometric identifier that is followed by at least one subsequent biometric identifier in a particular order;

accessing a biometric identifier database to retrieve a predefined secret sequence of biometric identifiers, including;

detecting the first biometric identifier received via the biometric scanner and the input circuit; and

retrieving the secret sequence of biometric identifiers based on detection of only the first biometric identifier;

comparing the input sequence of biometric identifiers to the secret sequence of biometric identifiers to obtain a result; and

based on the result, allowing access to a resource provided by the computing device.

18. The method of claim 17, wherein accessing the biometric identifier database to retrieve the secret sequence of biometric identifiers comprises:

calculating a hash key based on the first biometric identifier; and

using the hash key to retrieve the secret sequence of biometric identifiers in a hash table.

19. The method of claim 18, wherein the secret sequence of biometric identifiers is stored in the hash table, the hash table indexed by a checksum hash.
