A multimode system for receiving data in a retail environment includes: a secure input module for receiving high security input and low security input from a customer, the high security input to be communicated by the secure input module in cipher text, and the low security input to be communicated by the secure input module in plaintext. The multimode system is adapted to operate in a high security mode and a low security mode. The multimode system is adapted to enter the low security mode upon detection by the multimode system of a security breach condition. In the high security mode, the secure input module accepts low security input and high security input. In the low security mode, the secure input module accepts the low security input and does not accept the high security input.

Systems and methods for point-to-point encryption compliance are disclosed. In one embodiment, in a point of interaction device comprising at least one computer processor, a method for point-to-point encryption compliance may include: (1) receiving card data from a card reading device; (2) determining an error with the card data; (3) generating substitute data by replacing at least a portion of the card data with substitute data; and (4) communicating the substitute data to a payment server. The card data may be received from a magnetic stripe reader, from an EMV card reader, or from a contactless card reader. The error may include comprises the card data not being compliant with ISO-7813.

In a method for using and maintaining user data stored on a smart card, a smart card receives a user data request for the user data stored on the smart card. The smart card determines whether the user data request is a data maintenance request or a data use request. A data maintenance request is for modifying user data stored on the smart card. A data use request is for read only access to user data stored on the smart card. The smart card uses a first process to determine whether to allow the user data request when the user data request is determined to be a data maintenance request. The smart card uses a second process, different from the first method, to determine whether to allow the user data request when the user data request is determined to be a data use request.

Card including a substrate, at least one biometric data entry device on the substrate to receive biometric data about an individual holding the substrate, a memory component on the substrate and containing biometric data about an individual possessing the card and at least one private key, and a processor configured to compare biometric data received via the biometric data entry device to biometric data contained in the memory component to determine whether they match. When there is a biometric data match, a process requiring use of the private key(s) is initiated for authorized use of the card. A chassis intrusion detector system detects tampering with the card and upon such detection, causes deletion of the private key(s) to thereby prevent unauthorized use of the card.

An electronic device may include a printed circuit board having a physically unclonable function (PUF) source. The electronic device may also include an integrated circuit (IC) chip positioned on the printed circuit board, and the first PUF source may be embedded in or formed on the printed circuit board external to the IC chip. The IC chip has processing circuitry that is configured to determine PUF data based on the PUF source. The processing circuitry is further configured to determine a cryptographic key or authentication token based on the PUF data and to perform at least one secure operation using the cryptographic key or authentication token.

In accordance with a first aspect of the present disclosure, a user authentication system is provided, comprising: a user authentication token, said user authentication token comprising a fingerprint sensor and a secure element; an assistance device configured to be coupled to the user authentication token through an interface of said user authentication token; wherein the assistance device is configured to request the secure element to verify a personal unlock key to be captured by the secure element through the fingerprint sensor; wherein the secure element is configured to capture the personal unlock key through the fingerprint sensor, to verify the captured personal unlock key and to enroll, upon or after a positive verification of the personal unlock key, fingerprint reference data captured through the fingerprint sensor. In accordance with a second aspect of the present disclosure, a corresponding method for enrolling fingerprint reference data in a user authentication token is conceived. In accordance with a third aspect of the present disclosure, a corresponding computer program is provided.

In an approach, a locking device comprises a lock cylinder, a first solenoid valve and a second solenoid valve, a barcode scanner adjacent to the lock cylinder, a spring-loaded interface adjacent to the lock cylinder, and a logical circuit comprising a first disc and a second disc. In an approach for using a hybrid security key in a non-networked device, a locking device of the non-networked device authenticates logical and physical attributes of a hybrid security key, determines authorizations of the hybrid security key, and audits use of hybrid security key while in the locking device of the non-networked device.

Embodiments of the invention are directed to systems, methods and computer program products for generating unique marker codes for security implementation and deployment during authentication required resource disbursement. In this way, marker codes may be generated and associated with one or more resource disbursement mechanisms. The marker codes may be distributed and stored at third party devices. Upon identification of an input of a marker code, a specific response may be triggered. One or more marker codes may be associated with each disbursement mechanisms triggering various levels of responses from monitoring the resource disbursement to queuing communication with third party authorities for real-time dispatch. Thus, the system creates marker codes associated with non-obvious cues that control resource disbursement.

A credential reader update system includes a server operable to provide a credential reader update via a cellular telephone interface, and a plurality of credential readers. Each credential reader communicates with a presented credential at a credential reader frequency, wherein each credential reader has a credential reader interface having a range. A portable update device is movable into and out of the range, and is operable to receive the credential reader update via the cellular telephone interface. A credential reader update application is included in the portable update device, and is operable to uniquely identify the particular credential reader to be updated. The portable update device transfers the credential reader update to the credential reader via the credential reader interface, and the credential reader update includes firmware instructions that cause the credential reader to perform communications with the presented credential at a second frequency different than the credential reader frequency.
