  • Patent number: 11362824
    Abstract: This disclosure relates to systems and methods for managing protected electronic content using proxy reencryption techniques. Rights management architectures are described that may, among other things, provide end-to-end protection of content keys from their point of origination at a content creator and/or content service to end user devices. Proxy reencryption techniques consistent with aspects of the disclosed embodiments may enable transformation of a ciphertext under one public key to a ciphertext containing the same plaintext under another public key. Consistent with embodiments disclosed herein, proxy reencryption processes may be implemented using indistinguishability obfuscation and puncturable public-key encryption schemes, functional encryption, and/or white box obfuscation techniques.

  • Patent number: 11334547
    Abstract: Some embodiments are directed to a data retrieval device 210 for data-obliviously copying a subarray of a first array to a second array. The length of the second array is more than one and less than the length of the first array. The length of the subarray is at most the length of the second array. For each first element at a first index in the first array, the data retrieval device selects a second index in the second array for the first index in the first array; data-obliviously computes a choice bit indicative of whether to copy the first element to the second index in the second array; and replaces a second element at the second index in the second array by a replacement element, the replacement element being data-obliviously set to the first element or the second element based on the choice bit.

  • Patent number: 11288397
    Abstract: Textual masking for multiparty computation is provided. The method comprises receiving masked input data from a number of contributors, wherein the input data from each contributor has a unique contributor mask value. A unique analyst mask factor is received for each contributor, computed by an analyst as a difference between a uniform analyst mask value and the contributor mask value. An API call is received from the analyst to aggregate the input data from the contributors. The respective analyst mask factors are added to the input data from the contributors, and the data is aggregated and shuffled. Computational results received from the analyst based on the aggregated input data are published. In response to API calls from the contributors, the analyst mask factors are removed from the computational results, wherein computational results received by each contributor are masked only by the respective contributor mask value.

  • Patent number: 11283793
    Abstract: Techniques for securing user sessions using a time-based one-time password (TOTP) generated from a shared secret. The shared secret can be a cryptographic hash of one or more user credentials. In response to a successful authentication based on the user credential(s), a session is created. The authentication is performed in connection with an initial access request from a client application. A subsequent access request for a protected resource during the session is processed by extracting a session cookie and a TOTP and generating a corresponding TOTP using the shared secret. The TOTP can be generated by combining the shared secret with one or more additional parameters such as a Uniform Resource Locator associated with the resource, or the session cookie. Access to the protected resource is conditioned upon the session, which is identified by the session cookie, being valid and upon the TOTPs matching.

  • Patent number: 11276051
    Abstract: Systems and methods for conducting convenient and secure mobile transactions between a payment terminal and a mobile device, e.g., in a fueling environment, are disclosed herein. In some embodiments, the payment terminal and the mobile device conduct a mutual authentication process that, if successful, produces a session key which can be used to encrypt sensitive data to be exchanged between the payment terminal and the mobile device. Payment and loyalty information can be securely communicated from the mobile device to the payment terminal using the session key. This can be done automatically, without waiting for the user to initiate a transaction, to shorten the overall transaction time. The transaction can also be completed without any user interaction with the mobile device, increasing the user's convenience since the mobile device can be left in the user's pocket, purse, vehicle, etc.

    Abstract: An apparatus and method for determining a source of an unauthorized copy of speech signals in a conference call session. A conference bridge receives a speech signal during a conference call session with a plurality of end user devices attending. The conference bridge provides one or more dynamic, end user specific watermarks corresponding to the one or more end user devices. Each watermark is adjusted based on characteristics of the speech signal to make the watermark imperceptible to a human being. The speech signal is then embedded with the adjusted watermark in real time to generate a modified speech signal.

  • Patent number: 11245536
    Abstract: Secure multi-party computations may be used to get attribution results without compromising user privacy. A content provider and an advertiser may each sign a calculation indicating that they wish to share data using a secure multi-party computation. A measurement company may sign the calculation indicating that the measurement company has evaluated the computation and that the computation will protect user privacy. A user device may confirm with the verification service that all parties have signed the calculation. The user device may transmit one-time identifiers to the measurement company, which allows impression data and conversion data stored by the content provider and the advertiser to be linked. The content provider, the advertiser, and the measurement company may perform the secure multi-party computation, which allows the advertiser to evaluate attribution results without accessing the user data stored by the content provider.
