Abstract: There is provided apparatus, systems and methods that secure payment systems and other financial transaction systems by integrating the location of the transaction into transaction (e.g. payment) authentication processing. One or more methods, apparatus and systems are provided for authenticating a financial transaction made by a payer using a financial transaction processing system such as a payment system. The location of the payer and at least a portion of the financial transaction processing system (e.g. a location of the point of transaction) are verified by an authentication system and confirmed by the payer using a payer communication device.

Abstract: A method of verifying public parameters from a trusted center in an identity-based encryption system prior to encrypting a plaintext message by a sender having a sender identity string may include: identifying the trusted center by a TC identity string, the trusted center having an identity-based public encryption key of the trusted center based on the TC identity string; determining if the sender has a sender private key and the public parameters for the trusted center including the public encryption key of the trusted center and a bilinear map; and verifying the public parameters using the TC identity string prior to encrypting the plaintext message into a ciphertext by comparing values of the bilinear map calculated with variables from the trusted center. The ciphertext may include a component to authenticate the sender once the ciphertext is received and decrypted by the recipient using the private key of the recipient.

Abstract: A system and method of generating a graphical password is provided. User input into from input device is acquired based upon a grid point of a two dimensional grid mapped to the input device. A haptic input state of a haptic input device is acquired when the grid point when selected by the user. A tuple is generated based upon positional coordinates of the input device at the grid point and a value associated with the haptic input state of the haptic input device. A password can then be generated comprising multiple tuples.
