A system for permitting a secure electronic transaction on a network is disclosed. The network has a user device having a fingerprint, a provider's server and a means for providing verification of user's identity. In response to a request by the provider's server the means for providing verification positively identifies the fingerprint of the user device. It thereupon requests a confirmation from the user device of the transaction and upon receiving the confirmation completes the transaction.

An electronic transaction system, which facilitates secure electronic transactions among multiple parties including cardholders, merchants, and service providers (SP). The system involves electronic cards, commonly known as smart cards, and their equivalent computer software package. The card mimics a real wallet and contains commonly seen financial or non-financial instruments such as a credit card, checkbook, or driver license. A transaction is protected by a hybrid key cryptographic system and is normally carried out on a public network such as the Internet. Digital signatures and challenges-responses are used to ensure integrity and authenticity. The card utilizes secret keys such as session keys assigned by service providers (SPs) to ensure privacy for each transaction. The SP is solely responsible for validating each participant's sensitive information and assigning session keys. The system does not seek to establish a trust relationship between two participants of a transaction. The only trust relationship needed in a transaction is the one that exists between individual participants and the SP. The trust relationship with a participant is established when the SP has received and validated certain established account information from that particular participant. To start a transaction with a selected SP, a participant must have the public key of the intended SP. Since the public key is openly available, its availability can be easily established by the cardholder. The SP also acts as a gateway for the participants when a transaction involves interaction with external systems.

There is disclosed a method for performing secure electronic transactions on a computer network, the network comprising a buyer's computer, a vendor server, a creditor server and a security server. The buyer's computer has a fingerprint file stored in the memory thereof. The method includes the steps of: i) the buyer computer requesting to purchase merchandise to the vendor server, the purchase request including said buyer computer's IP address; ii) the buyer computer selecting a predetermined form of secured payment method; iii) the payment method selection causing the vendor server to transmit to the security server a request for confirmation of the buyer computer's identity at the buyer computer's IP address; iv) the confirmation request causing the security server to send a retrieval request to the IP address, the retrieval request including a retrieval program for detecting and retrieving the buyer's computer's fingerprint file, and the retrieval request further comprising a response request asking for confirmation of the purchase request; whereby a positive response from the buyer's computer to the security server accompanied by the fingerprint file causes the security server to confirm the buyer computer's identity to the vendor server and to approve the purchase.

Methods, computer program products and systems for authenticating an electronic transaction conducted over an electronic communications link with a user device of a transaction authorizer. A method includes establishing the electronic communications link with the user device of the authorizer, receiving an authentication code from an authorizer RFID over the electronic communication link, and determining if the received authentication code matches a stored authentication code assigned to the authorizer. The electronic transaction may proceed if the stored authentication code matches the received authentication code. Also included may be the step of determining if one or more required personal attributes match stored personal attributes associated with the stored authentication code assigned to the authorizer. If so, then the method may include proceeding with the electronic transaction if the one or more required personal attributes match the stored personal attributes associated with the stored authentication code assigned to the authorizer.

Aspects of the invention provide a solution for detecting man-in-the-middle attacks in electronic transactions using prompts. One embodiment includes a method for authenticating an electronic transaction. The method includes: receiving an electronic transaction request from a user, determining an IP address associated with a client system from which the electronic transaction request originates, providing the user with a password associated with the electronic transaction request, receiving a telephonic communication from a telephonic device associated with the user, prompting the user, via a voice response unit, to input the password using the telephonic device, authenticating the user by comparing the inputted password and the provided password, determining a probable location of the user based on the determined IP address of the client system, communicating to the user the probable location of the user based on the determined IP address, and prompting the user to confirm the probable location of the user.

The systems and methods described herein allow an electronic transaction to be performed upon determining, via biometric data, that an authorized individual is conducting the transaction. This may involve receiving, by a computer system, a request to authorize an electronic transaction for an account. The computer system is configured to access a phone number, which is stored in computer memory and associated with the enrolled user of the account. An automated and outward call to the phone number is performed by the computer system. The computer system is configured to capture a voiceprint in association with voice data received from the automated call. The captured voiceprint is compared to a registered voiceprint, which is stored in the computer memory in association with the enrolled user. The computer system responds to the request to authorize the secure electronic transaction based on said comparison.

A secure non-volatile solid state memory data key appears similar to a conventional USB flash drive modified to have a physical shape resembling a door key with an eyelet for attaching the data key to a key ring or lanyard. The data key includes a USB port, a microprocessor (effectively serving as the “chip” in the chip-and-pin configuration), and a secure memory for holding secure transaction information, such as credit and debit card numbers, verified personal identification (federated ID), and other secure data. A biometric sensor (e.g., touch sensor or “capcha”) verifies that a person is in physical possession of the data key before permitting access to the secure memory. The touch sensor may be limited to use by a unique individual person through a biometric reader, such as a finger print reader, where the verification finger print is stored on the key rather than the connected host device.

A corresponding system for secure electronic transactions is also provided.

Methods and systems for authenticating a security device for providing a secure access and transaction authorization to a remote network location are provided. The security device is authenticated by installing private security software on the security device. In order to authorize a transaction, a transaction authorization is performed using the security device by display a QR (Quick Response) code from an authorization server on a user terminal and scanning the QR code into the security device. After scanning the QR code, an OTA (One-Time-Authorization) code is sent from the security device to the authorization server for verifying the transaction. Embodiments of the present invention provide increased security and privacy. A corresponding system for authenticating a security device and preforming secure and private transactions is also provided.

The transaction is made between an object and a terminal. According to the invention, an authentication value is inserted in the object which is a digital signature appearing on an identifier of the object. Each object also has a diversified key created from a base key diversified by the identifier. The terminal can thus authenticate the identifier and check that the debit has actually been made.
