Dynamic web content personalization may be used to alter a web page such that two different people who view that web page do not see the exact same content on that page. The present disclosure includes techniques that allow a web page to be structured, via underlying source code, so that content can be dynamically generated based on a user transaction history. Further, dynamic content customization can effectively change the layout and functionality of a web page in ways not previously contemplated. For example, different control elements may become accessible based on a particular contextual user profile assigned to a user based on a transaction history. Modular content modules may also have a different appearance for different users.

A system and method for transacting cryptographic currency is described. An exchange database associated with a number of buyers and sellers is maintained at a host computer system. Cryptographic currency is received from one or more of the sellers at an exchange wallet associated with the exchange database. A match is created within the exchange database, including a buy offer for the cryptographic currency from a buyer and a sell offer for the cryptographic currency from a seller. A cryptographic currency withdrawal request is received from the buyer, and in response, the host computer system determines that a total amount of cryptographic currency represented in the exchange database matches a total amount of the cryptographic currency within the exchange wallet, transfers the cryptographic currency to the buyer's wallet, and updates the exchange database by deducting a first value of the cryptographic currency that is transferred to the buyer's wallet.

A system enables entities to access a single platform in order to utilize electronic data storage for storing different types of information. One or more computers may operate an electronic data storage processing network that entities can access when updating information in electronic data storage. The electronic data storage processing network may operate a plurality of electronic data storage processing modules, which can include an aggregator module, a formatter module, an operator signer module, and a validator module. Based on the specific use case for which electronic data storage is utilized, recordable data that is to be added to the electronic data storage can be processed by the appropriate aggregating, formatting, signing, and validating functions provided by the electronic data storage processing modules.

Systems and methods are provided for authenticating users to accounts in connection with network transactions. An exemplary method includes receiving an authentication request associated with a transaction where the authentication request includes a credential associated with the account, and transmitting an authentication assertion request to an entity associated with the account other than an access control server (ACS) associated with an issuer of the account. The method also includes providing an authentication confirmation, in response to the authentication request, when the entity provides an authentication assertion for the transaction based on a prior authentication of the user, whereby the transaction proceeds based on the authentication confirmation and without authentication specific to the transaction. The method further includes seeking authentication of the user, based on the authentication request, from the ACS, when the entity provides instruction to seek authentication of the user or fails to respond to the authentication assertion request.

A system and techniques are described herein for providing authentication. The technique includes registering user authentication data such as biometrics data with a communication device. The authentication data is linked to an account or service provider, and is used to verify the identity of the user when accessing the account. The communication device may obtain a public/private key pair, for which the pubic key may be stored on a secure remote server. When the user attempts to access the account or service provider, the user may provide the authentication data to authenticate the user to the communication device. Thereafter, the communication device may sign an authentication indicator using the private key and send the authentication indicator to the secure remote server. Upon verification of the signature using the public key, the secure remote server may grant access to the user, for example, by releasing a token.

A device and associated methods for entering a PIN via tapping are disclosed. The device can be configured to determine a number of taps provided by a PIN holder on a touch sensor in representation of a PIN digit and to store the number of taps as a digit in a sequence that represents the PIN. Indications for interaction with the device can be provided to PIN holders in the form of auditory cues. A visually impaired PIN holder may be able to complete a PIN entry process by following the indications for interaction, tapping on a touch sensor a number of times equal to the value of the digit of the PIN to be entered, and performing gestures mapped to commands for the device.

Embodiments of the present invention are directed to a “one-click payment” scheme for streamlining customers' online checkout experiences. According to one particular embodiment, a customer can use a computing device to be authenticated and receive a unique, one-time token to make a one-click payment during an online checkout process. The one-time token may be encrypted and directly associated with a payment account which the customer is authorized to access. The online merchant may forward a transaction request including the one-time token and purchase amount to an authorization server which would verify the token and charge the corresponding payment account.

A method for sending a transactional message assigns a universal transactional account (UTA) identifier to a customer, associates the assigned UTA identifier with a customer account corresponding to the customer, assigns an account network address corresponding to a service provider, stores, in a routing database, the UTA identifier in association with the account network address, creates, using a second terminal including a processor, the transactional message comprising the UTA identifier and a value, and sends the transactional message to the service provider, the sending the transactional message to the service provider including using the routing database to look up the account network address corresponding to the UTA identifier and transmitting the transactional message to the account network address.

Described are a system, method, and computer program product for customizing functions of a point-of-sale (POS) terminal. The method includes receiving payment device data from an electronic payment device of a user during a payment transaction between the user and a merchant. The method also includes receiving at least one script for execution on the POS terminal from the electronic payment device. The at least one script is associated with a digital signature. The method further includes verifying the at least one script based on the digital signature of the at least one script and executing the at least one script on the POS terminal to cause an action associated with a user interaction with the POS terminal to be performed.

A banking system of a financial institution maintains a plurality of customer accounts in math-based currency (“MBC”). The system includes a network interface configured to facilitate data transmission over a network. The system includes a ledger including information relating to the plurality of customer accounts associated with a plurality of customers. The system includes a processor configured to update information contained in the ledger relating to the plurality of customer accounts based on the occurrences of MBC transactions involving the plurality of customers.
