Communication System Using Cryptography Patents (Class 380/255)
  • Patent number: 10050719
    Abstract: A first photon in single-photon state is created when one of two photons created by parametric down conversion of a pump light is detected at a first detector. The first photon is divided into two components by a polarization beam splitter, and the first component is sent to a sender while the second component is sent to a receiver, with information that one of the two photons is detected. The sender selects whether he measures the first component or not according to the signal that he wants to transmit to the receiver. The second component of the first photon and a probe light enter into the second nonlinear optical medium. The receiver detects the phase modulation of the probe light caused by the interaction with the second component using homodyne detection during a first span after he receives the information from the first detector.

  • Patent number: 10050925
    Abstract: Messages sent on behalf of a user through an intermediary service message are assigned a unique sender address including unique message identification data unique to each message being sent. The unique sender address further includes message delivery system domain data identifying the actual domain of the intermediary service. The unique message identification data is also mapped to a user routing address. The unique sender address is then used to populate the “From” field of the message. Consequently, any message response sent to the “From” field of the message can be automatically analyzed to identify the user identification data in the unique sender address and automatically mapped to the user notification routing address. A notification of the response message can then be automatically relayed to the user using the user notification routing address.

  • Patent number: 10038676
    Abstract: Techniques described herein may be used to encrypt a telephone call between users. User devices (e.g., smart phones) may be connected to encryption relay devices that operate as relays between headsets worn by the user and the user devices. As information passes from the headset toward a corresponding user device, an encryption relay device may encrypt the information before the information reaches the user device so that the user device transmits encrypted call information to the other user participating in the call. When encrypted information is received, and travels from the user device to the headset, the encryption relay device may decrypt the information before it reaches the headset. Thus, the techniques described herein provide an end-to-end encryption solution to telephone calls.

  • Patent number: 10027631
    Abstract: Described herein are various technologies pertaining to constructions of a password-based authentication protocol that are configured to allow a user to register with and authenticate to an online service without the online service receiving a password or a deterministic function of the password of the user. When registering with an online service, a client computing device establishes a cryptographically strong random secret and stores an encryption of such secret with a data storage device. The storage device also never receives the password or a deterministic function of the password. When the user wishes to authenticate to the online service, the user employs her password to retrieve the encrypted secret from the storage device, decrypts such secret, and utilizes the decrypted secret to answer a cryptographically strong challenge provided to the user by the online service upon the online service receiving a username pertaining to such user.

    Abstract: Biometric information from an initial sample is used to generate a biometric template for a user. The biometric template is split into multiple template shares using a polynomial secret sharing scheme, such that at least some threshold number of the resulting template shares must be combined to reconstruct the biometric template. After the biometric template is split, the resulting template shares are distributed to multiple components in the system, such as a server, and/or one more user devices, and the original copy of the biometric template is destroyed. To subsequently verify the identity of the user, the threshold number of template shares are obtained and combined to reconstruct the user's biometric template, and the reconstructed template is compared with biometric information extracted from one or more subsequently collected biometric samples. If there is a match between the reconstructed biometric template and the extracted biometric information, the user's identity is verified.

  • Patent number: 9930543
    Abstract: A gateway turns encrypted PS data traffic on the Iub interface into clear IP packets so that WAN stream de-duplication and other optimization can be performed to eliminate the transfer of repetitive data across the Iub interface, thereby increasing the throughput between the NodeB and the RNC of the WCDMA network. The gateway pulls PS data traffic out from Iub without disturbing the signaling and CS traffic. The bifurcated PS data traffic is redirected to the GTP I/O port of the gateway where the stream de-duplication is applied. Deployment of the gateway is transparent to the WCDMA network. No network reconfiguration is required to deploy the gateway on the Iub interface.

  • Patent number: 9917978
    Abstract: A watermark generator for providing a watermark signal as a sequence of subsequent watermark coefficients based on a stream of subsequent stream values representing discrete valued data includes a differential encoder. The differential encoder is configured to apply a phase rotation to a current stream value of the stream values representing the discrete valued data or to a current watermark symbol, the current watermark symbol corresponding to a current stream value of the stream values representing the discrete valued data, to obtain a current watermark coefficient of the watermark signal. The differential encoder is configured to derive a phase of a previous spectral coefficient of a watermarked signal which is a combination of the host signal and the watermark signal, and to provide the watermark signal such that a phase angle of the phase rotation applied to the current stream value or the current watermark symbol is dependent on the phase of the previous spectral coefficient of the watermarked signal.

  • Patent number: 9916601
    Abstract: An ad-marketplace system manages an exchange for advertisement opportunities from a plurality of content brokers. Each advertising opportunity can include one or more attributes that describe advertisement slots during a broadcast of a data stream. The ad-marketplace system can receive one or more bids for an advertising opportunity associated with a media stream, and can select a matching bid from an advertiser for the advertising opportunity. Each bid can specify one or more advertising requirements that are to be satisfied by the advertising opportunity. When the ad-marketplace system selects the matching bid, the ad-marketplace system establishes a contract between the media broker, and places an initial payment from the advertiser in escrow. The ad-marketplace system can provide a payment to the media broker after confirming that a set of consumers have consumed the advertisement.

  • Patent number: 9906952
    Abstract: Methods, systems, and devices are described for the prevention of network peripheral takeover activity. In some embodiments, peripheral devices may implement an anti-takeover mechanism encrypting messages and transmitting unencrypted decryption keys for a limited period of time. Anti-takeover peripheral devices may transition from a plain operational mode, to a decryption key transmission mode, to a secure mode based on pre-defined triggering events, commands, or timers. Random decryption key values may be generated by peripheral devices and transmitted to listening devices for later storage and retrieval by the listening device. Decryption keys may be stored in remote data stores for later retrieval by anti-takeover aware controller devices.

  • Patent number: 9906239
    Abstract: Systems, apparatuses, and methods for implementing a parallel Huffman decoding scheme are disclosed herein. A system with a plurality of execution units receives a Huffman encoded bitstream. The system partitions the encoded bitstream into a plurality of chunks. Each execution unit is assigned to decode a separate chunk of the encoded bitstream as well as an extra portion of an adjacent chunk. With this approach, the decoding of the bitstream overlaps for a programmable amount of data at each chunk boundary since each execution unit, excluding the first execution unit decoding the first chunk of the bitstream, will likely decode a certain number of symbols incorrectly at the beginning of the chunk since the chunk boundaries will not be aligned with symbol boundaries. The system determines, from the decoded extra portion at each chunk boundary, where incorrectly decoded ends and where correctly decoded data begins for each decoded chunk.

  • Patent number: 9904934
    Abstract: This disclosure is directed to techniques and systems to enable customers to make secure electronic payments to entities (e.g., merchants, vending machines, etc.). The entities may be at brick-and-mortar locations or other locations where the entities are “offline” and may not readily receive payments from customers that have payment accounts stored and managed by a host. In various embodiments, a customer may direct the host to transfer a payment to a merchant after the customer and merchant exchange a code that includes a payment instruction. The code may be used in place of usernames, passwords, or other personal information and may be difficult for others (e.g., bystanders, etc.) to intercept. After the exchange of the code, the customer may authorize the host to a transfer payment to the merchant based on the payment instruction.

  • Patent number: 9898497
    Abstract: A user interface may be designed to receive conflicting data from multiple data sources during a merger of legacy computer systems. The interface automatically validates the conflicting data against each other to generate a final data set for review. Summary information for each data set can be displayed in a single interface such that the summary data sets are individually selectable and provide an overview of the data merger process for each data set. By drilling down through the summary data, the user interface can display individual data sets where data conflicts can be resolved, missing data can be provided, and duplicate data can be eliminated. When the merger process is complete, the interface can translate the data set into a standardized format that can be exported to form generation modules to generate, for example, a welcome letter based on the translated data set.
