A payment card comprises an internal dynamic card verification value (CVV) generator and a user display for card-not-present transactions. Card-present transactions with merchant card readers are enabled by a dynamic magnetic array internally associated with the card's magnetic stripe. The user display and a timer are triggered by the user when the user needs to see the card verification value and / or begin a new transaction. A new card verification value is provided for each new transaction according to a cryptographic process, but the timer limits how soon a next new card verification value can be generated.

A method for securing financial transactions involving payment cards includes associating a sixteen-digit personal account number (PAN) with a particular payment card and user, wherein are included fields for a system number, a bank / product number, a user account number, and a check digit. A four-digit expiration date (MMYY) associated with the PAN. A magnetic stripe on the payment card is encoded with the PAN for periodic reading by a magnetic card reader during a financial transaction. A table of cryptographic values associated with the PAN and the MMYY is stored on each user's payment card during personalization by an issuing bank. A next financial transaction being commenced with the payment card is sensed. A cryptographic value from the table of cryptographic values is selected for inclusion as a dynamic portion of the user account number with the PAN when a next financial transaction is sensed. Any cryptographic value from the table of cryptographic values will not be used again in another financial transaction after being used once. The issuing bank authorizes the next financial transaction only if the PAN includes a correct cryptographic value in the user account number field.

A payment card financial transaction authenticates for providing overall financial network security computes a number of results from a cryptographic key that match values that were selectively used to personalize individual payment cards with their individual user identification and account access codes. An account access code is later presented daring a financial transaction involving at least one of those individual payment cards. A dynamic portion is included in a merchant's magnetic reading of the payment card. Then authenication can proceed by matching it with values computed from the cryptographic key.

A payment card fraud detection business model comprises an internal virtual account number generator and a user display for Card-Not-Present transactions. Card-Present transactions with merchant card readers are enabled by a magnetic array internally associated with the card's magnetic stripe. The internal virtual account number generator is able to reprogram some of the magnetic bits encoded in the magnetic stripe to reflect the latest virtual account number. The internal virtual account number generator produces a sequence of virtual numbers that can be predicted and approved by the issuing bank. Once a number is used, such is discarded and put on an exclusion list or reserved for a specific merchant until the expiration date. A server for the issuing bank logs the merchant locations associated with each use or attempted use, and provides real-time detection of fraudulent attempts to use a virtual account number on the exclusion list. Law enforcement efforts can then be directed in a timely and useful way not only where the fraud occurs but also at its origination.

A new PIN code is provided for each new transaction according to a cryptographic process, but the timer limits how soon a next new PIN code can be generated and displayed.

An storage area network (SAN) has a manager digital data processor that includes a first element that maintains a first representation of the SAN and a second element that maintains a second representation of the SAN. The first element generates notifications of events in the SAN, e.g., addition or removal of components or relationships between components, and includes with them data pertaining to the event. The second element responds to such notifications and data by updating the second representation. That data is preferably sufficient for the second element to update the second representation without further reference to information contained in the representation.

The present invention relates generally to the classification of items into categories, and more generally, to the automatic selection of different classifiers at different places within a hierarchy of categories. An exemplary hierarchical categorization method uses a hybrid of different classification technologies, with training-data based machine-learning classifiers preferably being used in those portions of the hierarchy above a dynamically defined boundary in which adequate training data is available, and with a-priori classification rules not requiring any such training-data being used below that boundary, thereby providing a novel hybrid categorization technology that is capable of leveraging the strengths of its components. In particular, it enables the use of human-authored rules in those finely divided portions towards the bottom of the hierarchy involving relatively close decisions for which it is not practical to create in advance sufficient training data to ensure accurate classification by known machine-learning algorithms, while still facilitating eventual change-over within the hierarchy to machine learning algorithms as sufficient training data becomes available to ensure acceptable performance in a particular sub-portion of the hierarchy.

Data in the second queue is grouped in accord with the task to which they correspond.

The present invention relates to systems, apparatus, and methods of determining whether to abort a prefetch operation. Embodiments include accumulator functionality for accumulating object data prior to making an abort determination. Certain embodiments compress the accumulated data to more accurately reflect the cost of pushing the data to the client as part of the prefetch operation. Accumulation and / or compression of the data may provide sufficient data relating to the size of the object to make a useful prefetch abort determination, even where the size of the object cannot be otherwise determined (e.g., from the object data header). Other embodiments store accumulated data (e.g., in compressed or uncompressed form) for use in further optimizing prefetch operations. For example, if an accumulated prefetch is aborted before the object is forwarded to the client, and the client later requests the object, the object may be pushed to the client from server-side storage, rather than retrieving (e.g., and compressing) the object from the content server redundantly.

It includes a process that generates for application to the output device a plurality of graphical object that represent “segments” of the SAN and / or components of the SAN, along with the interconnections between them. The process selectively responds to operator / administrator selection of any of the graphical objects that represent a segment by regenerating the display to depict the interconnected segments and / or components that make up that segment.
