Abstract: Methods and apparatus are described for processing transactions from untrusted sources which reduce the risk of a maliciously instructed transaction being processed at a target environment and thus preventing undesirable behaviour resulting from processing the transaction occurring at the target environment. An execution manager is provided to process transactions/portions of transactions in an emulated environment and monitor the resultant effects. Following execution of the transaction at the emulated environment, it is determined whether undesirable behaviour occurred at the emulated environment and whether the transaction may be executed in the target environment. The method enables transactions from untrusted sources to be processed with minimal risks of malicious consequences occurring at the target environment.

Abstract: An apparatus and methods are provided to defending device against attacks. When it is determined that a device is under attack, a determination is made as to whether a layout of objects within said at least one resource at said device is protecting said device against said attack. The determination is then transferred to a remote server together with a layout of the resource at the device. When it is determined that the layout of objects within the at least one resource at the device is not protecting the device against the attack, then the layout of the at least one resource is changed. Either the remote server or the device may determine whether to change the layout in response to the attack.

Abstract: A computer-processor-implemented data processing method comprises: a computer processor executing instances of one or more processing functions, each instance of a processing function having an associated function-call identifier; and in response to initiation of execution by the computer processor of a given processing function instance configured to modify one or more pointers of a partitioned acyclic data structure: the computer processor storing the function-call identifier for that processing function instance in a memory at a storage location associated with the partitioned acyclic data structure; for a memory location which stores data representing a given pointer of the partitioned acyclic data structure, the computer processor defining a period of exclusive access to at least that memory location by applying and subsequently releasing an exclusive tag for at least that memory location; and the computer processor selectively processing the given pointer during the period of exclusive access in depende

Abstract: Provided is a technology including an apparatus and a machine-implemented method for updating software on a device, the method performed at the device comprising: receiving a software update manifest comprising an authenticated resource request identifier and an authenticated definition identifying one or more characteristics of the device; generating a software update request comprising a value for each of the one or more identified characteristics of the device; transmitting, to a location corresponding to the resource request identifier, the built software update request; receiving a resource enabling access to or including a software update appropriate for the one or more values of the one or more identified characteristics; and updating the software of the device in accordance with the software update.

Abstract: A method of authorizing an operation on a remote device with a cryptographic signature verification component, the remote device being operable in a communications network having human-readable messages with message signatures, comprising receiving at an arbitrator an authorization request to perform an operation requiring authorization on the remote device; retrieving from the request an operation identifier and plaintext data; sending a human-readable request with the identifier and the plaintext data to an authorizer; receiving a reply from an authorizer, the reply message comprising at least the plaintext data and a verifiable cryptographic signature identifying the authorizer derived from the request; and on receiving the reply, sending a request to perform the operation to the remote device with an authorization derived from at least the cryptographic signature, the cryptographic signature being suitable for verification by the cryptographic signature verification component on the remote device.

Abstract: A system allows the identification and protection of sensitive data in a multiple ways, which can be combined for different workflows, data situations or use cases. The system scans datasets to identify sensitive data or identifying datasets, and to enable the anonymisation of sensitive or identifying datasets by processing that data to produce a safe copy. Furthermore, the system prevents access to a raw dataset. The system enables privacy preserving aggregate queries and computations. The system uses differentially private algorithms to reduce or prevent the risk of identification or disclosure of sensitive information. The system scales to big data and is implemented in a way that supports parallel execution on a distributed compute cluster.
