Abstract: A system for facilitating acquisition of items on behalf of a requesting device is provided. The system comprises an application that when executed on a computer publishes a listing of items specified by a first device, the items available from online vendors designated in the specification. The system also receives an instruction from a second device to purchase a first item in the listing of items. The system also purchases, based on the instruction, the first item from a first online vendor of the online vendors, and directs the first online vendor to ship the first item to a specified address. The specified address is provided by the first device. The system further verifies availability and price of the first item with the first online vendor prior to purchasing.

Abstract: Techniques are disclosed for authenticating transactions conducted over computer networks, e.g., online banking transactions or other transactions performed by a financial institution at a customer's request. After receiving a transaction request (and associated transaction details), the transaction signing service signs the transaction data and sends the resulting blob to the user requesting the transaction. After being transmitted to the user, the signed transaction data itself is then signed using PKI credentials of the user, which then returns the twice-signed bundle to the financial institution. Rather than rely on the cryptographic signature of the client, the financial intuition (or other replying party) validates that the transaction data signed using its own highly trusted key has not been altered prior to being signed and returned by the client.

Abstract: Systems and methods for synchronizing verification data in a distributed database including client and server databases. The server database may exchange verification data regarding one-time passwords to multiple client databases. An update to the server database may be initiated based on information stored in the client database by pushing updated verification information from the client database to the server database via an SSL tunnel. An update to the client database may be initiated based on information stored in the server database by pulling updated verification data from the server database to the client database via an SSL tunnel. The client database and the server database may include a two-dimensional data field including the verification data and an associated key identifier, and a site ID. The site ID may include a unique identifier to identify the respective database in which it is included.
