Abstract: A transaction authentication system authenticates a transaction by determining whether a mobile device and POS device involved in the transaction are at the same location. A POS registry stores location data for POS devices. A PAN registry stores mobile device IDs corresponding to account numbers. A mobile device ID can be provided from the PAN registry in response to receiving an account number from a POS device. The mobile device ID can then be used to retrieve location information from a home location register maintained by a mobile service provider. The retrieved location data for a POS device and the retrieved location data for a mobile device are compared.

Abstract: Provided is a method for operating an authentication server for authenticating a user who is communicating with an enterprise via a network. The method includes receiving, via the network, a first authenticator including first information from a low energy wireless device received via a user device wirelessly, and storing the first authenticator. When the authentication service later receives, from the enterprise, a request to authenticate the user, the authentication server transmits an authentication request to the user device via the network requesting that the user read information from the low energy wireless device using the user device. The information received from the low energy wireless device in response to the authentication request is then used to authenticate the user by comparing the information received from the low energy wireless device due to the authentication request with the stored first authenticator.

Abstract: A communications management system for implementing a freeze on electronic transactions. For example, a device management system provides a means of preventing the porting of at least one communication device account—such as a cellular phone number—from one carrier to another through a list of identifiers that include phone numbers, device identifiers, or personal identifiers that have been enrolled in the device management system through an interface by an authorized user. Advantageously, the device management system provides a revision to the existing phone porting architecture and enables fraud detection and prevention.

Abstract: Provided is a method for authenticating a user communicating with an enterprise via a network. The method includes receiving, via the network, authenticators for a user from a first user device associated with the user, and storing the received authenticators. A first authenticator from the stored authenticators is selected to be used for authenticating the user based on an authentication policy received from the enterprise. An authentication request is transmitted to a user device requesting the first authenticator and the user is authentication by comparing the received authenticator with the stored first authenticator.

Abstract: The disclosed embodiments relate to a system that authenticates and/or identifies a user of an electronic device based on passive factors, which do not require conscious user actions. During operation of the system, in response to detecting a trigger event, the system collects sensor data from one or more sensors in the electronic device. Next, the system extracts a feature vector from the sensor data. The system then analyzes the feature vector to authenticate and/or identify the user, wherein the feature vector is analyzed using a model trained with sensor data previously obtained from the electronic device while the user was operating the electronic device.

Abstract: A system and method allows users to make purchases utilizing a mobile subscriber account.

Abstract: To provide a user signature on a network transaction, a security server receives transaction information representing a transaction between a network user and a network site, such as a website, directly from the network site. The security server calculates a one-time-password based on the received transaction information and a secret shared by the security server and the network site, but not by the user. The security server transmits the calculated one-time-password for application as the user's signature on the transaction. The one-time-password is independently calculable by the network site based on the shared secret.

Abstract: Briefly, in accordance with one embodiment, a method and/or system for mobile identity authentication is disclosed. For example, mobile identity authentication may be employed in a variety of situations, including purchases, financial transactions, granted access to accounts, granting access to content, etc.

Abstract: A system and method allows users to make purchases by charging or funding a prepaid debit card with their cell phone accounts by simulating a user roaming with their mobile device.

Abstract: Briefly, in accordance with one embodiment, a home country associated with a current mobile telephone number for a mobile subscriber is identified. Other countries, such as the following are also identified: a country in which the mobile subscriber is using the internet; a country in which the mobile subscriber is roaming, is operating a current mobile telephone associated with the mobile subscriber's mobile provider account or is operating a current mobile telephone having a SIM card associated with the mobile subscriber's mobile account; a country in which a merchant for a transaction is located; and/or a country in which goods in the transaction, if any, are being shipped. The countries are compared and scoring is employed to facilitate identification of a suspicious transaction.

Abstract: Briefly, in accordance with one embodiment, a mobile subscriber is registered for authentication. Registering the mobile subscriber, in an embodiment, includes querying the mobile service provider of the mobile subscriber for an international mobile subscriber identifier (IMSI) of the mobile subscriber at the time of registration and creating an authentication database in which a database entry includes at least: a mobile telephone number for the mobile subscriber and the IMSI of the mobile subscriber.
