  • Patent number: 11928875
    Abstract: Described herein is a mechanism for visual recognition of items or visual search using Optical Character Recognition (OCR) of text in images. Recognized OCR blocks in an image comprise position information and recognized text. The embodiments utilize a location-aware feature vector created using the position and recognized information in each recognized block. The location-aware features of the feature vector utilize position information associated with the block to calculate a weight for the block. The recognized text is used to construct a tri-character gram frequency, inverse document frequency (TGF-IDP) metric using tri-character grams extracted from the recognized text. Features in location-aware feature vector for the block are computed by multiplying the weight and the corresponding TGF-IDF metric. The location-aware feature vector for the image is the sum of the location-aware feature vectors for the individual blocks.

  • Patent number: 11588726
    Abstract: Disclosed herein are systems and methods for creating an ultra-lightweight multi-tenant network virtualization model by augmenting an OSI layer 4 tuple (protocol, source IP address, destination IP address, source port, destination port) with additional private gateway-specific source and destination augmented addresses. A unique OpenVPN Augmented Address (OAA) may be created and assigned to each device on a network such as a mesh-linked system. This OAA may form part of a packet shim created with routing path information for both the source and the destination resources. Once created, the shim may be inserted into a packet header for transmission. Once the initial packet is transmitted, each hop creates its own resources for managing transmission of subsequent packets in this session. The packet shim operates to establish a communications session on layer 4 (Transport) between the requestor and the target resource which is intermediate-device agnostic.

  • Patent number: 11354400
    Abstract: Data from a SaaS application may be stored and accessed locally, enabling SaaS data to be interacted with, regardless of connectivity, while providing secure authentication when offline. When online, a user may perform an authentication procedure and provide credentials to an application server, which may provide an authentication token for access to secure data or applications. The authentication token and user credentials may be cached locally. When offline or experiencing intermittent connectivity, if user provided credentials match the cached credentials, then the client application may retrieve the cached authentication token and allow the embedded browser to resume utilizing the network application and/or data; while if the new credentials do not match the previously provided and cached credentials, access may be denied. Thus, the embedded browser may perform authentication agnostic to whether the device is online or offline at that time, requiring no changes to the browser or network application.

  • Patent number: 11108569
    Abstract: A system, method, and computer program product to renewably prevent traitors in a broadcast encryption system from re-using compromised keys. A license agency assigns individual receivers a set of Sequence Keys preferably at manufacture, and assigns Sequence Key Blocks (SKBs) to protected content files to be distributed. The files may be distributed on prerecorded media and typically include several file modifications. The particular modifications in a pirated version of a file can help identify which traitors contributed to its theft. SKBs assigned to new files distributed after traitors have been identified cannot be usefully processed using the compromised keys employed in previous content piracy. Innocent receivers that happen to have compromised key(s) in common with traitors can use a replacement uncompromised Sequence Key from the set to usefully decrypt content. Traitors will however step through all their Sequence Keys without reaching one that will work.

  • Patent number: 11042669
    Abstract: A cryptographic ASIC and method for autonomously storing a unique internal identifier into a one-time programmable memory in isolation by a foundry. The identifier may be determined by calculating a transformed hash of a predetermined input, and may serve as a cryptographically defined and verifiable CpuID for a particular ASIC instance. The CpuID may be derived from an input based on a manufacture date, a wafer lot number, a wafer number, row and column coordinates for a die on a wafer, or other foundry-defined data. The CpuID enables a given ASIC instance to be securely and remotely identified across an untrusted network, and to serve as a specified processor that originates an information stream or a message. The ASIC need not always perform high-speed calculations and so may be relatively simple and inexpensive, and in one embodiment serves as a secure data administrator that manages subscriptions and software updates.
