Abstract: In certain embodiments, a presentation of a user interface may be dynamically modified for a user based on data related to the user's email address or other user identifier. As an example, the user interface may be caused to reflect the look and feel of an interface of an entity trusted by the user, incorporate data items related to the user's identifier, or effectuate other modifications. In some embodiments, a user identifier of a user may be received via a user interface associated with the third party, and a query for data related to one or more user accounts associated with the user identifier may be generated. Based on the query, multiple datasets associated with different user accounts may be received, and a first dataset associated with a first account of the user may be selected over other datasets associated with the user's other accounts effectuate the presentation modification.

Abstract: Various embodiments are directed to techniques for ensuring that a negotiable instrument has not been altered between the time the instrument leaves the hands of the payor and when the check is presented for redemption by the payee by recording an image of the check in a data block in a blockchain and retrieving the image when the check is presented for redemption for comparison with the check. A match between the stored image and the check indicates that no alteration of the check has occurred.

Abstract: An authenticated data sharing system may include a contactless card comprising a processor and a memory including one or more applets and an application comprising instructions for execution on a device. The application is configured to determine a capability associated with the contactless card after a first entry into a communication field. The application is configured to request additional information based on the determination. The one or more applets are configured to transmit, to the application, a generated tokenized link after a second entry into the communication field based on the requested additional information. The application is configured to transmit the link to obtain the requested additional information.

Abstract: A password-less authentication system and method include registering a contactless card of a client with an application service and binding the contactless card to one or more client devices. The contactless card advantageously stores a username and a dynamic password. Accesses by the client to the application service may be made using any client device, and authentication of the accesses may be performed by any client device that includes a contactless card interface and can retrieve the username and dynamic password pair from the contactless card. By storing the username on the card, rather than requiring user input, application security improved because access to and knowledge of login credentials is limited. In addition, the use of a dynamic password reduces the potential of malicious access.

Abstract: Account registration using a contactless card. A payment application executing on a device may receive a request to generate a payment account using a contactless card. The payment application may receive encrypted data from the contactless card and transmit the encrypted data to a server associated with the contactless card. The device may receive a push notification from the server and open an account application associated with the contactless card responsive to selection of the push notification. The account application may receive confirmation to generate the payment account using the contactless card and transmit the confirmation to the server. The device may open the payment application responsive to receiving verification of the encrypted data from the server. The payment application may fill form fields with account data received from the server and generate the payment account using the account data received from the server filled into the form fields.

Abstract: Example embodiments of systems and methods for data transmission system between transmitting and receiving devices are provided. In an embodiment, each of the transmitting and receiving devices can contain a master key. The transmitting device can generate a diversified key using the master key, protect a counter value and encrypt data prior to transmitting to the receiving device, which can generate the diversified key based on the master key and can decrypt the data and validate the protected counter value using the diversified key.

Abstract: A system and method are disclosed that leverage multi-factor authentication features of a service provider and intelligent call routing to increase security and efficiency at a customer call center. Pre-authentication of customer support requests reduces the potential for misappropriation of sensitive customer data during call handling. A contactless card uniquely associated with a client may provide a second factor of authentication via a backchannel to reduce the potential for malicious third-party impersonation of the client prior to transfer of the call to the customer call center. Pre-authorized customer support calls may be intelligently and efficiently routed directly to call center agents, without incurring further delay. During call handling, call center agents may initiate further client authentication processes, including contactless card authentication requests, over one or more different communication channels for authorizing access to sensitive information or to allay suspicion.

Abstract: A device receives a transaction request concerning a transaction and a transaction card from a transaction terminal, and determines, based on the transaction request, information concerning the transaction card. The device sends, based on the transaction request and to a user device, a query concerning possession of the transaction card by a user of the user device, where the query includes an instruction for the user to confirm possession of the transaction card via a component of the user device. The device receives, from the user device and after sending the query to the user device, a response concerning possession of the transaction card by the user, and determines, based on the response and the information concerning the transaction card, whether the user has possession of the transaction card. The device performs, based on determining whether the user has possession of the transaction card, at least one action.
