Abstract: A first mobile phone is used to scan a barcode to launch a first mobile payment application on the first mobile device. A payment request is transmitted from the first mobile device to a second mobile device. The second mobile device is operated by a payment account holder. A second mobile payment application is launched in the second mobile device in response to receipt of the payment request. The payment request includes data obtained by the first mobile device scanning the barcode. A response is received from the payment account holder to the second mobile payment application. Payment account credentials are supplied via the second mobile device to conduct a transaction in accordance with the payment request. The payment account credentials identify a payment account belonging to the payment account holder.

Abstract: A mobile computing device has at least one processor and at least one memory together providing a first execution environment and a second execution environment logically isolated from the first execution environment. The following approach is taken to manage data items for an application executing the first execution environment. A trust relationship is established between a trust client in the second execution environment and a remote trusted party and the trust client receives one or more data items from the remote trusted party. On executing the application in the first execution environment, the trust client provides the data items or further data items derived therefrom to the application 213. Provision of these data items may be conditional upon a user authentication process. A suitable mobile computing device is also described.

Abstract: A mobile computing device has a processor and a memory. The processor is programmed with a mobile transaction application 101. The memory comprises a local database 102 to hold data items for use by the mobile transaction application 101. The mobile transaction application 101 is adapted to encrypt data items for storage in the local database 102 and to decrypt data items stored in the local database 102 using white-box cryptographic techniques.

Abstract: Instead of requiring key exchange between a trusted biometric application in a TEE and an external application outside of the TEE that provides access to a secured function, the trusted application is preconfigured with security data such as (in a first implementation) authentication credentials (e.g. a PIN) or (in a second implementation) a cryptographic key. This security data is then used to authenticate a biometric validation obtained by the trusted application to the external application.

Abstract: A system and method for generating an authentication token which is used by an issuer associated with a integrated circuit card to authenticate a transaction. A personal card reader receives data, including an authentication cryptogram, from the integrated circuit card. The personal card reader uses the data received from the integrated circuit card to select one of at least two default bitmaps stored in a memory portion of the personal card reader. The personal card reader uses the selected default bitmap and the authentication cryptogram to build the authentication token.

Abstract: The present invention relates to a method and system for synchronising a personal identification number (PIN) value stored in a mobile computing device, with a PIN value stored on a remote server. The remote server receives a request from the mobile computing device to record a PIN value, the request comprising the PIN value. The PIN value is recovered from the received request and stored at the remote server. An instruction set arranged to record the PIN value in a secure hardware element comprised within the mobile computing device is generated and transmitted to the mobile computing device. The instruction set executes on the mobile computing device in order to record the PIN value on the secure hardware element.
