    Abstract: According to an example, trusted function based data access security control may include determining a restriction set by a first entity and related to access to and/or analysis related to data under the control of the first entity. A trusted function including meta-data that describes a transformation of the data may be ascertained. A determination may be made as to whether the meta-data of the trusted function matches the restriction related to the access to and/or analysis related to the data. In response to a determination that the meta-data of the trusted function matches the restriction, the trusted function may be executed to allow controlled access to the data by a second entity. In response to a determination that the meta-data of the trusted function does not match the restriction, execution of the trusted function may be prevented to prevent access to the data by the second entity.

    Abstract: In one implementation, a data sharing system can comprise a trust engine to identify an environment that satisfies a level of trust, an access engine to request access to a set of data, a procedure engine to receive a procedure, a restriction engine to receive a semantic restriction associated with a semantic term of the environment, a tracker engine to track the procedure during execution, and a control engine to maintain execution of the procedure based on the restriction and trace information. In another implementation, a method for sharing a set of data can comprise validating an environment satisfies a level of trust, receiving a procedure to access the set of data, receiving a semantic restriction associated with a semantic term of the environment, tracing the procedure during execution, and providing a view of the set of data based on the restriction and a semantic mapping of trace information.

    Abstract: In one implementation, a data sharing system can comprise a trust engine to identify an environment that satisfies a level of trust, an access engine to request access to a set of data, a procedure engine to receive a procedure, a restriction engine to receive a restriction associated with a resource of the environment, a monitor engine to maintain resource utilization information, and a control engine to limit execution of the procedure based on the restriction and the resource utilization information. In another implementation, a method for sharing a set of data can comprise validating an environment satisfies a level of trust, receiving a restriction associated with a resource of the environment, receiving a procedure to access the set of data, ascertaining resource utilization information, and providing a view of the set of data based on the restriction and the resource utilization information.

    Abstract: Storing and retrieving ciphertext in data storage can include determining a first ciphertext value for a first data chunk to be saved to a client-server data storage system using an encrypted chunk hash value associated with the first data chunk as an initial value, and storing the first data chunk on a server in the client-server data storage system in response to determining that the first ciphertext value is a unique ciphertext value. Also, storing and retrieving ciphertext in data storage can include decrypting a ciphertext value for a second data chunk received from a client in the client-server data storage system and based on an encrypted chunk hash value associated with the second data chunk, and sending the second data chunk to the client in response to determining that the decrypted ciphertext value corresponds to an original data chunk saved to the server by the client.
