Tokenless biometric transaction authorization system

A method for tokenless authorization of commercial transactions at retail points of sale between a buyer and a seller who are co-located, using a computer system and at least one biometric input apparatus, wherein the buyer may select from one of many registered financial accounts, said method comprising the steps of:

• a. a buyer registration step, wherein the buyer registers with the computer system a PIN, at least one registration biometric sample, and at least one buyer financial account, where each buyer financial account is assigned an abbreviated account index code;
• b. a seller registration step, wherein the seller registers with the computer system at least one seller registration financial account, and at least one biometric input apparatus that uniquely identifies the seller to the computer system using a seller identification code;
• c. a proposal step, wherein the seller proposes a commercial transaction to the buyer;
• d. an acceptance step, wherein the buyer signals acceptance of the seller's proposed commercial transaction by directly entering into the biometric input apparatus the buyer's personal authentication information comprising a PIN, an abbreviated account index code, and at least one bid biometric sample to the proposed commercial transaction, forming a transaction agreement;
• e. a transmission step, wherein the transaction agreement is forwarded to the computer system;
• f. a seller identification step, wherein the computer system compares the seller identification code with previously registered seller identification codes for producing either a successful or failed identification of the seller;
• g. a buyer identification step, wherein the computer system compares the personal authentication information in the transaction agreement with previously registered biometric samples for producing either a successful or failed identification of the buyer;
• h. an account selection step, wherein the computer system obtains a buyer financial account using the abbreviated account index code from the transaction agreement;
• i. a payment step, wherein upon determination of sufficient resources, the buyer financial account is debited and a financial account of the seller is credited;
• and
• j. a presentation step, wherein any combination of the results of steps a) through j) are presented to the buyer or seller, wherein a commercial transaction is conducted without the buyer using any portable man-made memory devices such as smartcards or magnetic stripe cards for identifying the buyer.

A method for tokenless authorization of commercial transactions at retail points of sale between a buyer and a seller who are collocated and who are using a computer system and at least one biometric input apparatus, wherein the buyer may select from one of many registered financial accounts, one of said accounts being an emergency account used to send a silent alarm during coerced transactions, with the computer system being authenticated to the buyer by the presentation to the buyer of a secret private code upon successful buyer identification, said method comprising the steps of:

• a. a buyer registration step, wherein the buyer registers with the computer system a PIN, at least one registration biometric sample, a secret private code which is distinct from the PIN and is not used to gain access to the computer system, at least one buyer financial account, where each buyer financial account is assigned an abbreviated account index code, and at least one emergency account index code;
• b. a seller registration step, wherein the seller registers with the computer system at least one seller registration financial account, and at least one biometric input apparatus that uniquely identifies the seller to the computer system using a seller identification code;
• c. a proposal step, wherein the seller proposes a commercial transaction to the buyer;
• d. an acceptance step, wherein the buyer signals acceptance of the seller's proposed commercial transaction by entering into the biometric input apparatus the buyer's personal authentication information comprising a PIN, an abbreviated account index code, and at least one bid biometric sample forming a transaction agreement;
• e. a transmission step, wherein the transaction agreement is forwarded to the computer system along with the seller identification code that uniquely identifies the seller, the seller identification code being provided by the biometric input apparatus;
• f. a seller identification step, wherein the computer system compares the seller identification code with previously registered seller identification codes for producing either a successful or failed identification of the seller;
• g. a buyer identification step, wherein the computer system compares the personal authentication information in the transaction agreement with previously registered biometric samples for producing either a successful or failed identification of the buyer;
• h. an account selection step, wherein the computer system selects a buyer financial account using the account index code from the transaction agreement, and if the account index code is the same as the emergency account index code, a silent alarm is sent;
• i. a payment step, wherein upon determination of sufficient resources, the buyer financial account is debited and a financial account of the seller is credited;
• and
• j. a presentation step, wherein any combination of the results of steps a) through i) are presented to the buyer or seller, and upon successful identification of the buyer, the buyer's secret private code is presented to only the buyer.

• e. a transmission step, wherein the transaction agreement is forwarded to the computer system;
• f. a seller identification step, wherein the computer system compares the biometric input apparatus code with previously registered biometric input apparatus codes for producing either a successful or failed identification of the seller;

• i. a presentation step, wherein any combination of the results of steps a) through h) are presented to the buyer or seller,
• wherein a commercial transaction is conducted without the buyer using any portable man-made memory devices such as smartcards or magnetic stripe cards for identifying the buyer.
