  • Patent number: 11301834
    Abstract: Systems and methods are provided for use in extending dialogue between a mobile device and a point-of-interaction. One exemplary computer-implemented method includes receiving, at a point-of-interaction (POI) computing device, an identifier for an interaction with a user where the identifier is specific to a card associated with an account of the user or to the user in general, and submitting, by the POI computing device, a request for the identifier to a registration database to determine whether the account is registered for one or more services. The method then includes, in response to the request, receiving an encrypted action (associated with a service), encoding, by the POI computing device, a receipt for the interaction, and transmitting, by the POI computing device, the encoded receipt and the encrypted action to a host server for initiating the encrypted action between the POI computing device and a mobile device associated with the user.

  • Publication number: 20200273038
    Abstract: A transaction takes place between a first device and a second device. There is an authorisation system associated with the first device and a transaction support system associated with the second device. The transaction support system and the authorisation system are connected by a transaction infrastructure. A communication path is provided between the second device and the transaction support system. The second device is adapted to take the following actions. It performs a transaction with the first device and receives and generates transaction data. It splits the transaction data into basic transaction data and enhanced transaction data. It provides the basic transaction data to the transaction support system over the communication path. It also provides the enhanced transaction data by a separate route to the authorisation system for reconciliation with the processed transaction provided by the transaction support system for use by the authorisation system in authorising the transaction.

  • Patent number: 8056132
    Abstract: Software robots (“bots”) may be detected in a client computer using a client-side bot detector. The client-side bot detector may be configured to receive bot event profiles indicating IP (Internet Protocol) addresses involved in malicious online activities perpetrated by bots and time frames when the malicious online activities occurred. The client-side bot detector may determine dynamic IP addresses that have been dynamically assigned to the client computer by consulting a dynamic IP assignment profile of the client computer. The client-side bot detector may compare the bot event profiles against the dynamic IP assignment profile of the client computer to determine if the client computer is infected by a bot.
