A computing device comprises: a memory; a processor; an interpreter; and a Memory Management Unit. The interpreter is for controlling the processor to execute a program comprising at least one first instruction in a format that is not native to the processor and at least one second instruction in machine code that is native to the processor. The Memory Management Unit is adapted to control access by the processor to the memory and possibly also to peripherals when the at least one second instruction is executed.

Secure execution of native code

There is disclosed a method of providing a software update to a secure element comprised in a host device, comprising converting the software update into a sequence of ciphertext blocks using a chained encryption scheme, and transmitting said sequence of ciphertext blocks to the host device. Furthermore, there is disclosed a method of installing a software update on a secure element comprised in a host device, comprising receiving, by the host device, a sequence of ciphertext blocks generated by a method of providing a software update of the kind set forth, converting said sequence of ciphertext blocks into the software update, and installing the software update on the secure element. Furthermore, corresponding computer program products and a corresponding host device are disclosed.

An embedded device () having a memory () that is organized to store both data objects (DO-DOx) and meta data (MD) which describes the locations at which the data objects are stored in the memory (), the embedded device () which is connectable to a remote defragmentation device () is disclosed. The embedded device () is adapted to transmit, at the request of the defragmentation device (), the meta data (MD) and optionally the data objects (DO-DOx) stored in the memory () to the defragmentation device () and, in accordance with instructions and data received from the defragmentation device (), to update in its memory () the meta data (MD) and to store the data objects (DO-DOx) at locations as defined in the updated meta data (MD).

A method for analyzing fingerprint images includes picking up a sequence of images at very short time intervals, while a finger is being placed onto an electronic fingerprint sensor. A criterion for recognizing a live finger is extracted from variations in the images. The images are defined as a pixel raster having different gray values, with the aid of which the pixels are assigned binary values of zero or one. Significant changes in the values are detected and compared, with the aid of distinctive numbers or the like, to known typical changes that occur regularly in a particular image class.

Method for analyzing fingerprint images

The method enables automatic triggering of pattern recognition tasks. A histogram of the frequency distribution of the gray-scale values of the image is determined periodically and repeatedly from the available image information. The characteristics of the histogram are determined, and the characteristics are used as the basis for establishing whether a relevant pattern is present. If the relevant pattern is found to be present, the pattern recognition process is initiated.
