Abstract:
An integrated circuit substrate of an aspect includes a plurality of exposed electrical contacts. The integrated circuit substrate also includes an inaccessible set of Physically Unclonable Function (PUF) cells to generate an inaccessible set of PUF bits that are not accessible through the exposed electrical contacts. The integrated circuit substrate also includes an accessible set of PUF cells to generate an accessible set of PUF bits that are accessible through the exposed electrical contacts. Other apparatus, methods, and systems are also disclosed.
Abstract:
Generally, this disclosure describes a method and system for automated check-out and drop-off return of products using a mobile device. A method may include purchasing at least one product of a plurality of products wherein each product is located at a respective associated product location in a store that sells the plurality of products and a point of sale of each purchased product corresponds to the respective associated product location.
Abstract:
Ein Prozessor eines Aspekts enthält Stammschlüssel-Generierungslogik, um einen Stammschlüssel zu generieren. Die Stammschlüssel-Generierungslogik enthält eine Quelle für statische und entropische Bits. Der Prozessor enthält auch Schlüsselableitungslogik, die mit der Stammschlüssel-Generierungslogik verkoppelt ist. Die Schlüsselableitungslogik dient zum Ableiten eines oder mehrerer Schlüssel aus dem Stammschlüssel. Der Prozessor enthält auch kryptografische primitive Logik, die mit der Stammschlüssel-Generierungslogik verkoppelt ist. Die kryptografische primitive Logik dient zum Durchführen kryptografischer Operationen. Der Prozessor enthält auch eine Sicherheitsgrenze, die die Stammschlüssel-Generierungslogik, die Schlüsselableitungslogik und die kryptografische primitive Logik umfasst. Andere Prozessoren, Verfahren und Systeme werden ebenfalls offenbart.
Abstract:
An apparatus for sharing information between entities includes a processor and a trusted execution module executing on the processor. The trusted execution module is configured to receive first confidential information from a first client device associated with a first entity, seal the first confidential information within a trusted execution environment, receive second confidential information from a second client device associated with a second entity, seal the second confidential information within the trusted execution environment, and execute code within the trusted execution environment. The code is configured to compute a confidential result based upon the first confidential information and the second confidential information.
Abstract:
Systems, devices, and methods used to provide real-time product information for retail products and services are generally disclosed herein. One example embodiment includes a referral application operating on a smartphone, configured to correlate data from multiple sources and provide context-aware recommendations and information relevant to a product or service being evaluated by a consumer in the physical shopping environment (such as a retail store). For example, the data may be obtained from a retailer's product information database, a retailer's competitor information database, an advertiser information database, an Internet-hosted service, a social network, or similar internal or external information sources. The real-time product information may be correlated, aggregated, and displayed to the user to either facilitate the retail purchase in the store, or encourage another online or retail purchase. Techniques for providing location-based advertisements and tailored product offerings based on the user's shopping activity are also described herein.
