Abstract: Multi-blend fingerprinting may be detected. First, a video sample may be received. Next, frames of the received video sample may be step iteratively through until a probability value corresponding to a current frame indicates a match. Deciding that the probability value indicates the match may comprise creating an augmented frame, determining the probability value corresponding to the created augmented frame, and determining that the probability value indicates the match. Then a fingerprint from the created augmented frame may be extracted.

Abstract: Embodiments of the invention provide a method of authenticating an item by affixing an RFID chip to the item. In one embodiment, an authentication method comprises providing an RFID chip having a unique ID readable by a device; applying the chip to an item via an adhesive; associating the ID of the chip with the item at a first point in time; and at a second point in time later than the first point in time, authenticating the item by reading the ID of the chip applied to the item and comparing with the ID associated with the item at the first point in time. The RFID chip cannot be easily removed and preferably cannot be removed without visible evidence of tampering, more preferably without destroying the RFID chip so that the ID of the RFID chip cannot be read.

Abstract: A portable electronic data storage/processing device, e.g., smart card maintains an account including benefit packages. Each benefit package includes multiple items with associated quantity information. A smart card includes an account benefits interface and a retailer interface, each interface using different security measures. New benefit packages are added to the smart card through the account benefit interface by a benefit provider. Benefits debit request lists including multiple items and associated quantities are submitted to the smart card through the retailer interface. The smart card is the trusted member and checks if all requested items in quantities requested can be debited. If all requests can be fulfilled, the smart card executes the debiting from the currently valid benefit package and returns a transaction success indication to the retailer. If any of the requests of the list cannot be met, the entire request list is rejected and no debiting occurs.

Abstract: An electrolyte comprises a composite of a polymer and a molten salt electrolyte immobilized within the polymer. The electrolyte is stable and ionically conducting at a temperature substantially equal to the melting point of the molten salt electrolyte. In this form, the electrolyte is suitable for use in electrochemical cells, supercapacitors or electrochromic windows and displays.
