摘要： A system receives an audio-video recording that includes image frames. For each image frame, a portion of the image frame is identified that corresponds to a first face of a first subject. An image region is determined for the identified portion of the image frame. A first face portion of the audio-video recording is stored that corresponds to the determined image region for each of the image frames along with a private key for the audio-video recording and a first mask identifier for the first subject. A public key is generated for the private key. A remaining portion of the audio-video recording is associated with the generated public key and the first mask identifier for the first subject. The remaining portion, the public key, and the first mask identifier are provided to a media server that communicates with a media player.

摘要： Techniques for obfuscating and/or de-obfuscating data using bit-level shard masks are disclosed. Shard masks are generated. The shard masks are designed to shard a block of data into a number of shards for distribution and storage among a number of storage arrays. The shard masks shard the block of data at a bit-level granularity. The shard masks are applied to the block of data to generate the shards. The shards are then distributed among the storage arrays for storage on the storage arrays.

摘要： Biometric data such as iris, facial, or fingerprint data may be obtained from a user. A public code may be generated from the biometric data, but does not obtain any of the biometric data or information that can be used to identify the user. The public code includes information that can be used to extract from the biometric data a biometric code that is suitable for bitwise comparison. Neither the underlying biometric data nor information from which the biometric data may be determined is stored as only the public code and the actual biometric feature of the user is required to generate the biometric code.

摘要： Systems and methods that may be used to provide multitenant key derivation and management using a unique protocol in which key derivation may be executed between the server that holds the root key and a client that holds the derivation data and obtains an encryption key. In one or more embodiments, the derivation data may be hashed. The disclosed protocol ensures that the server does not get access to or learn anything about the client's derived key, while the client does not get access to or learn anything about the server's root key.

摘要： A distributed computer network utilizing cryptography that includes one or more processors, wherein the one or more processors are programmed to receive a secret input state and one or more tuples, mask the secret input state with the one or more tuple and utilize a reveal to compute a masked input, compute six multiplications on the masked input, compute multiplication of two secret values to output an intermediate output, mask a third secret value from the intermediate output and reveal the third secret value to compute an interaction, compute a multiparty-computation multiplication with the interaction, and output a final secret value in response to computing the multiparty-computation multiplication.

摘要： An apparatus includes a processor and a memory operatively coupled to the processor and associated with an instance of a distributed database at a first compute device. The processor is configured to select an anonymous communication path. Each blinded public key from a sequence of blinded public keys associated with the anonymous communication path is associated with a pseudonym of a compute device from a set of compute devices that implement the anonymous communication path. The processor is configured to generate an encrypted message encrypted with a first blinded public key. The processor is configured to generate an encrypted data packet including the encrypted message and a compute device identifier associated with a second compute device. The encrypted data packet is encrypted with a second blinded public key. The processor is configured to send the encrypted data packet to a third compute device.

摘要： In one embodiment, a method for providing access to big data is disclosed. The method includes receiving biometric data of a user to provide access to columns of a table storing the big data, wherein one or more columns of the table are masked based on one or more data parameters and authenticating the user by comparing the biometric data of the user with pre-stored biometric data, wherein the pre-stored biometric data is retrieved from a biometric database. Further, the method includes providing upon the authentication, selective access to each column of the table based on a pre-defined user privilege for each column.
