TL;DR: In this paper, a system and methods for defining, observing and detecting triggering user account events that initiate a user account alert message to be sent to one or more users are disclosed.
Abstract: Systems and methods for defining, observing and detecting triggering user account events that initiate a user account alert message to be sent to one or more users are disclosed. Location and merchant, transaction result, device and, usage history/trend types of user account alerts and trigger criteria can be defined or selected by users, issuers were notification alert engines. Alternatively, user account alerts and trigger criteria can be defined by analyzing previously observed user account events, such as credit card transactions, to determine user profiles and user account usage trends, i.e. credit card spending patterns, as baselines for comparing newly observed user account events. If information associated with the newly observed user account events match any of the trigger criteria or are inconsistent with the determined user profile or user account usage trends, then user account alerts can be sent to one or more users.

TL;DR: In this article, the authors proposed a speaker verification system that allows the use of a captured voice sample attempting to reproduce a word string having a random element to authenticate the user, based on a match score indicating how closely the captured voice samples match to previously stored voice samples of the user and a pass or fail response indicating whether the voice sample is an accurate reproduction of the word string.
Abstract: Embodiments of the invention provide for speaker verification on a communication device without requiring a user to go through a formal registration process with the issuer or network. Certain embodiments allow the use of a captured voice sample attempting to reproduce a word string having a random element to authenticate the user. Authentication of the user is based on both a match score indicating how closely the captured voice samples match to previously stored voice samples of the user and a pass or fail response indicating whether the voice sample is an accurate reproduction of the word string. The processing network maintains a history of the authenticated transactions and voice samples.

TL;DR: In this article, the authors proposed a streamlined payment system that allows consumers to send transaction details for authorization to a mobile device (e.g., a mobile phone) instead of sending the transaction details to the merchant for authorization.
Abstract: Embodiments of the streamlined payment system described herein are directed to a consumer mobile device (e.g., a mobile phone) that sends transaction details for authorization, instead of the merchant sending the transaction details for authorization. This eliminates the need to present the consumer's payment account information to the merchant. The transaction details may include an amount and merchant payment initiation information. In one embodiment, the consumer mobile device may directly contact an issuer without using a traditional payment processing network. The issuer may then approve or deny the transaction and communicate directly with the issuer, merchant, or merchant's acquirer. In one embodiment, transaction details may need to be communicated from a computing device (e.g., a PC) operated by the consumer that is not collocated with the merchant. In this embodiment, the transaction details may be encoded into a particular format that can be received and read by the consumer's mobile device. The format may be a transaction details identifier or a transaction details data payload. The transaction details identifier or transaction details data payload may be an SMS or MMS message, barcode, watermarked image, or manual identifier that represents the transaction details. The SMS/MMS message with transaction details payload or identifier may be received by the mobile device. The barcode, text image, or watermarked image may be read using the mobile device's camera or other input means.

TL;DR: In this article, a method for the use of electronic transactional tokens includes: generating transactional token including a first token, associating each of the tokens with one of a group of users, monitoring usage of the transactional transactions by the users; and responsive to the monitoring, updating the first token from a first state to a second state.
Abstract: A method for the use of electronic transactional tokens includes: generating transactional tokens including a first token; associating each of the transactional tokens with one of a group of users; monitoring usage of the transactional tokens in a multitude of transactions by the users; and responsive to the monitoring, updating the first token from a first state to a second state. The tokens may be generated and monitored using a token processing system, which uses transaction data received by a transaction handler that is handling transaction processing for the transactions.
