  • Patent number: 11621846
    Abstract: A system includes a binary tree having leaf hashes. The leaf hashes include a device privacy protected index and a set of zero-knowledge commitments relating to a computer device. The system calculates the device privacy protected index using a verifiable random function such that a device entity path in the binary tree cannot reveal any information about any other device in the binary tree, and associates the set of zero-knowledge commitments with the device privacy protected index. The system then generates a privacy-protected attestation for the computer device using the device privacy protected index and the set of zero-knowledge commitments.

  • Patent number: 11616782
    Abstract: As a default, a global permissions model is established. The global permissions model serves for applying a first set of resource access permissions to shared content objects. Additionally, a set of context-aware access policies that govern user interactions over the shared content object is established. When a particular user requests an interaction over a shared content object, then interaction attributes associated with the request are gathered. The context-aware access policies are applied to the request by determining a set of extensible access permissions that are derived from the interaction attributes. The context-aware access policies are enforced by overriding the first set of resource access permissions with dynamically-determined access permissions. When a particular access request is denied, a response is generated in accordance with the set of extensible access permissions and the user is notified. In some cases, the access request is permitted, but only after the user provides a justification.

  • Patent number: 11431512
    Abstract: Described herein is a system and method for validating media integrity using asymmetric key cryptography utilizing a public/private cryptographic key pair. The private key is kept secret and is known to an originator and/or publisher of a media file. The public key is added to the media file and is used to validate integrity of the media file, that is, that content of the media file (e.g., portion(s), frame(s)) has not been altered since publication of the media file. By validating integrity of the media file, strong proof that the media file came from an owner of the keypair (e.g., had possession of the private key) can be obtained, for example, resolving issues of trust and/or authenticity common in altered content. In some embodiments, information regarding an origin of the content can further be determined.

  • Patent number: 11431514
    Abstract: During provisioning of a biometric device, a hardware root of trust is established between the biometric device and a server. The biometric device includes a cryptographic processor with a first encryption key stored in secure storage. The first encryption key is used to establish a mutually authenticated communication channel with the server. A set of additional encryption keys between the device and the server are established via the communication channel. Biometric data generated by the biometric device is encrypted using the additional keys and digitally signed. The server receives the encrypted and signed data via the communication channel and verifies the signature. Once the signature is verified, the biometric data is then decrypted. The server then processes the decrypted biometric data. Data that does not arrive via the communication channel, that fails the verification, or that fails decryption is deleted or disregarded.
