Abstract: Secure registration of a new application with a server system is provided. An old application has been registered with the system. A first link between the new application and the system establishes a first key and first check data is communicated from the system to the new application and passed to the old application. A second link between the old application and the system establishes a second key based on input of a credential to the old application; the first check data is communicated from the old application to the system. Enciphered second check data is communicated from the system to the old application over the second link and further encrypted by the old application using a third key. This generates doubly-enciphered check data which is passed to the new application and decrypted using the first key and a fourth key, generated at the new application based on the first check data and input of the credential to the new application.

Abstract: A method and device are described for maintaining software components in a portable electronic device. The device includes memory storing software components executable from the device, with associated pairs of logical storage partitions for storing different versions of the software components, a data interface for coupling the device to a host computer, a contactless interface for receiving payment token data from a contactless payment token, and a cellular network interface for communication of data over a cellular network. An upgrade process is initiated when the device is coupled to the host computer. Data including a different version of at least one of said software components is received, installed and executed to initiate a payment transaction with a remote system. Payment token data is received via the contactless interface means and transmitted to the remote system.

Abstract: A computer-implemented biometric identity verification method including the steps of storing a database of registered users, including data identifying profile attributes of each registered user and a respective plurality of stored biometric signatures, each stored biometric signature associated with a corresponding one or more of the profile attributes. A predicted biometric signature is derived for a requesting user when it is determined that a period of time has elapsed since the requesting user's stored biometric signature was last updated, by adapting the stored biometric signature based on biometric variances derived from a biometric peer group of registered users with at least one profile attribute in common with the requesting user. The predicted biometric signature is used to verify the identity of the requesting user.

Abstract: In a credential recovery process, a user is authenticated using an application running on a mobile communications device, and requests recovery of a credential. The application generates a session key encrypted with the public key of a gateway, and sends the encrypted key to the gateway. The gateway recovers the credential from a depository, encrypted using a symmetric key shared with the depository. The gateway decrypts the credential and re-encrypts the credential using the session key. Preferably, the decryption and re-encryption is performed within a hardware secure module within the gateway. The re-encrypted credential is sent to the application, which decrypts the credential and outputs it to the user. In this way, the credential is provided securely to the user and may be made available for use immediately, or nearly so.

Abstract: A method of user authentication by an application (1a) on a mobile telephony device (1) comprises authenticating the user by interaction with the application (1a), communicating with a remote authentication service (4) to receive a call identifier; and sending the call identifier within a telephone call to the remote telephony service (9), by means of which the user is authenticated to the remote telephony service (9). The mobile telephony device may receive a service code linked to the remote telephony service, and the call identifier may be based on this code. The service code may be captured or entered manually into the mobile device, or obtained from an application on the mobile device (1), such as a mobile banking application. The call identifier may be hidden within the call using audio steganography. The authentication service (4) may link the user to a remote service account ID, which is sent to the remote server.

Abstract: A user inputs a pattern consisting of a plurality of lines. The lines are classified by relative length, overall direction and degree of curvature. Where a line is started from a new position, the direction from the previous starting point is taken into account. The series of lines is then serialized into a key value, which may then be used to decrypt data stored on a device. This enables data to be securely stored since the key is supplied by the user at runtime and is not itself stored on the device.
