Abstract

The present invention relates to a computer program product, a computing device and a method of detecting a file encrypted by ransomware by identifying a file write operation for a file on the computing device and determining if a predetermined number of bytes of the file is stored in a memory buffer on the computing device. An entropy value of the predetermined number of bytes in the memory buffer is determined and compared to a first predetermined threshold, wherein if the determined entropy value exceeds the first predetermined threshold the file associated with the file write operation is flagged as being potentially encrypted by ransomware.

Abstract

Methods and systems employing augmented reality techniques via real-world objects for various purposes. Computer implemented methods are provided for animated augmentation of real-time video of static real-world objects. A computing device receives first data defining features and movements of a human subject, captures a video image of an object having features corresponding to human features, maps features defined by first data to corresponding features of the object, and uses the first data to animate the corresponding features of the object to correspond with the movements of the human subject defined by the first data. The object may be a physical 3D object. Embodiments may include positioning and orienting a 3D mesh representation of the object in registration with the object video image, prior to mapping the features defined by the first data to corresponding features on the 3D mesh. Recorded audio messages may be played in synchronism with the object.

Abstract

A network comprises a root node device and a plurality of non-root node devices, including at least one intermediate node and at least one leaf node that defines a network branch. The root node stores routing information that includes the address of each non-root node and a corresponding nexthop address, and that enables the root node to identify, for each intermediate node, a branch address, being the address of a leaf node that is reachable via that intermediate node. Each intermediate node stores a routing table that includes an entry for each leaf node reachable via that intermediate node, each entry comprising the branch address of the respective leaf node and a nexthop address in the direction of that branch address. The root node is configured to add, to a packet having one of the non-root nodes as its destination, the branch address of a leaf node that is reachable via the destination. Each intermediate node is configured to receive packets from its parent node and, if the intermediate node receiving the packet is not the destination of the packet, to read the branch address added to the packet by the root node, and to forward the packet to the nexthop address associated with the branch address in its routing table.

Abstract

Method and apparatus for the determination of moisture content in a hygroscopic material. Measurements of parameters such as the modulus of elasticity and the time of flight, are recorded on the material using two methods of measurement. The two methods are each affected differently by moisture content. The moisture content is derivable by taking a ratio of the measurements with a factor to account for the species or type of hygroscopic material. A non-destructive method for determining the absolute moisture content in wood,which provides measurements above the fibre saturation point, is described.
