    Abstract: A device implementing a system for authenticating an identity document includes at least one processor configured to receive, from a service provider, a request associated with verifying an integrity of an identity document, and capture, responsive to receiving the request, image data of the identity document. The at least one processor is further configured to generate a representation based on the image data, the representation comprising form factor data of the identity document, and compare the representation with a prior representation of the identity document, the prior representation comprising prior form factor data of the identity document. The at least one processor is further configured to provide, to the service provider, a response to the request based on comparing the representation with the prior representation.

    Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable media for enforcing application usage policies. As part of an application purchase transaction, the application distributor creates a unique proof of purchase receipt. This receipt can be bundled with the application and delivered to the purchaser. Each machine can maintain an authorization file that lists the users authorized to use applications on that machine. A system configured to practice the method verifies that a user is authorized to use an application on a machine based on an application proof of purchase receipt and the authorization file. If the application proof of purchase receipt and the authorization file are both valid, the system checks if the user account identifier in the receipt is contained in the authorization file. If so, the user can be considered authorized to use the application on the machine.

    Abstract: This application relates to embodiments for providing a content stream to a device from a content server based on a protocol that is established between the device and an account server. The account server can initiate a session with the device and provide the device with a list of channels available for a user account associated with the device. When a channel is selected at the device, conditional access information can be provided from the account server to the device, which can thereafter relay the conditional access information to the content server. The content server can use the conditional access information to verify that the device has the appropriate permission to receive streaming content. In this way, because the conditional access information originates at the account server, permission to access streaming content can be managed by correspondence between the account server and the device, rather than the content server.

    Abstract: The embodiments set forth systems and techniques to activate and provide other device services for user devices. An activation manager is configured to activate a user device by receiving an activation request for the device, accepting previously stored and encrypted trusted data for the device, getting current data for the device, determining whether the current data compares with the trusted data, and sending an authorization to activate the device when the current data compares favorably with the trusted data. Data can include a seed component divided into seed segments that are each combined with a unique device identifier using varying cryptographic primitives. Each encrypted seed segment and unique device identifier combination can be dedicated to a different device use or service, and can be used separately for device identification for that use or service.

    Abstract: Some embodiments provide for an improved method for performing AES cryptographic operations. The method applies a look up table operation that includes several operations embedded within look up tables. The embedded operations include a permutation operation to permute several bytes of AES state, a multiplication operation to apply a next round's protection to the AES state, an affine function and an inverse affine function to conceal the multiplication operation, and an inverse permutation operation to remove a previous round's protection. Some embodiments provide for an optimized method for efficiently performing such protected AES operations. The method alternates rounds of AES processing between software processing (e.g. processing by a CPU, performed according to software instructions) and hardware processing (e.g. processing by cryptographic ASIC).

    Abstract: Some embodiments provide a method for performing a block cryptographic operation that includes a plurality of rounds. The method receives a message that includes several blocks. The method selects a set of the blocks. The set has a particular number of blocks. The method applies a cryptographic operation to the selected set of blocks. A particular round of the cryptographic operation for a first block in the set is performed after a later round than the particular round for a second block in the set, while a different particular round for the first block is performed before an earlier round than the different particular round for the second block. In some embodiments, at least two rounds for the first block are performed one after the other without any intervening rounds for any other blocks in the set.
