    摘要: An execution device including a memory area, a stack and a hardware unit comprising two hardware registers. An ordered sequence of elements comprising bytecodes and operands is stored outside the execution device. The first register has a content set to a targeted element read from the ordered sequence, the memory area includes a series of software components comprising a translation in native language of a predefined set of bytecodes and ending with a specific native instruction requesting to execute the content of the first register. The hardware unit comprises a register manager adapted to automatically do:
    (i) each time said first register is read, updating the the first register content with the next element following the targeted element in the ordered sequence and increasing a program counter referencing the next element in the ordered sequence,
    (ii) each time said second register is read, updating the second register content with a value located on top of the stack and decreasing a stack pointer referencing the top of the stack,
    (iii) each time said second register is written, pushing the content of the second register onto the top of the stack and increasing the stack pointer.

    摘要: The present invention bypasses the static minutiae limitation bay allowing to enrich minutiae with recent acquired minutiae after a successful authentication and thus allowing to manage the evolution of the minutiae. It thus concerns a device (D) having a biometric sensor (BS) to acquire biometric minutiae (BM) from a user of the device (D), said device (D) having a stored minutiae reference (MR) for this user and a comparator (COMP) to compare the acquired biometric minutiae (BM) with the minutiae reference (MR) and to authenticate the user as soon as the comparison is above a matching threshold, the device (D) being characterized in that it comprises an enrichment module (ENRM) to detect a successful authentication, and upon successful authentication, to inspect the corresponding acquired biometric minutiae (BM) for relevant minutiae (RM) not known in the minutiae reference (MR) and to add or modify such relevant minutiae (RM) to the stored minutiae reference (MR) to enrich it.
