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.

A data management and storage (DMS) cluster of peer DMS nodes manages data of a tenant of a multi-tenant compute infrastructure. The compute infrastructure includes an envoy connecting the DMS cluster to virtual machines of the tenant executing on the compute infrastructure. The envoy provides the DMS cluster with access to the virtual tenant network and the virtual machines of the tenant connected via the virtual tenant network for DMS services such as data fetch jobs to generate snapshots of the virtual machines. The envoy sends the snapshot from the virtual machine to a peer DMS node via the connection for storage within the DMS cluster. The envoy provides the DMS cluster with secure access to authorized tenants of the compute infrastructure while maintaining data isolation of tenants within the compute infrastructure.

A system includes a purchase portal configured to receive a purchase order from a customer, wherein the purchase order includes a service from each of a plurality of service providers. When receipt of the purchase order is detected, a processor determines first and second ones of the service providers associated with the purchase order; and establishes a trust relationship between the first service provider and the second service provider in a context of the customer. The processor also sends a first request for a first trust artifact to the first service provider and a second request for a second trust artifact to the second service provider; receives the first trust artifact from the first service provider, receives the second trust artifact from the second service provider, sends the first trust artifact to the second service provider, and sends the second trust artifact to the first service provider.

Methods and systems are disclosed for a digital signature system using scalable and reliable servers. The system includes multiple frontend servers that are each in communication with multiple backend servers. A remote application server sends a signature request to one of the front end servers. The signature request includes at least two public keys that each have a different server identifier embedded in them. The backend server extracts one of the server identifiers and tries the signature generating process with the corresponding back end server. If that that backend server does not respond, then the frontend server extracts the server identifier from another public key and initiates the signature generation process with that backend server. In some systems, the remote application server has a predefined relationship with multiple frontend servers so that if one frontend server is down, the application server can communicate with a backup frontend server.

Systems and methods are disclosed herein for real-time digital authentication. According to some embodiments, a certification authentication method includes receiving a list of third party root certificates from a remote server, the list of third party root certificates including at least one association between a program configured to run on the computing apparatus and a public key for authenticating communication between the program and an associated server of the program. The method may also include authenticating the list of third party root certificates. The method may also include initiating a communication between the computing apparatus and the associated server and authenticating the communication with the associated server using the public key. Furthermore, the method may also include loading the program onto the one or more memories during a bootstrapping process in response to determining that the communication with the associated server is authentic.

Prompt and secure data communication paring concepts are described. In one example, a method for data communications includes a client device receiving an advertising packet from a peripheral device, comparing a signal strength indicator for the advertising packet to a threshold, generating a session key based on the comparing, and transmitting the session key to the peripheral device. The method also includes communicating and acknowledging one or more data chunks between the devices through a secure communications channel. The concepts are different that traditional pairing techniques for short-range, low-power wireless data communications in that secure communications channels can be achieved automatically, relatively more quickly, and repeatedly without the need for user intervention. The secure communications channels can be established and reestablished without the need for traditional pairing techniques.

Techniques are provided herein for secure display device communications. In one example, a video communications device provides, to a display device over a first connection, communication information that enables the display device to contact a server over a second connection. The video communications device further provides, to the display device over the first connection, a command configured to initiate an interaction with the server. The server obtains, from the display device over the second connection, a message initiating the interaction in response to the command based on the communication information.

The present disclosure relates to generating a passphrase for an encrypted volume by at least cryptographically combing the first cryptographic key and the shared secret. Where the shared secret is split into a plurality of shares and a first number of the plurality of shares is greater than a second number of the plurality of shares and the second number of the plurality of shares is required to reconstruct the shared secret.

A computer implemented method to detect a data breach in a network-connected computing system including generating, at a trusted secure computing device, a copy of data distributed across a network; the computing device accessing sensitive information for the network-connected computer system and searching for at least part of the sensitive information in the copy of the data; in response to an identification of sensitive information in the copy of the data identifying the sensitive information as compromised sensitive information.

A tamper resistant device can be used for an integrated circuit card. The device includes memory storing a first security domain that includes a telecommunication profile and a second security domain that includes an application profile. A first physical interface is configured to be coupled to a baseband processor configured to operate with a mobile telecommunications network. A second physical interface configured to be coupled to an application processor. The first physical interface configured to allow the baseband processor to access the telecommunication profile and the second physical interface is configured to allow the application processor to access the application profile. The tamper resistant device is configured to enable accessibility to the application profile if corresponding commands are received at the first interface and to enable accessibility to the telecommunication profile if corresponding commands are received at the second interface.
