This invention discloses a method and apparatus for improving the security of data cards, relating to the field of information security, and is invented to enhance the security of information stored in data cards. The method includes: binding a data card inserted into a first terminal to the first terminal; generating a decryption password; when a read / write operation is required on the data card, determining whether a second terminal requiring the read / write operation is the first terminal, and if so, decrypting the data card using the decryption password. This invention is mainly applicable to various data cards.

This invention provides an improved method, system, and computer program for performing matrix multiplication computer instructions. [Solution] The method is a processor having a control register and a vector register whose length is indicated in the control register, in which a matrix operation A × B = C is performed, where A is an M × K matrix with elements of a first bit width, B is a K × N matrix with elements of a second bit width, and C is an M × N matrix with elements of a third bit width. The instruction has three parameters that encode the type of multiplication to be performed and indicate which vector register to sequentially store the elements of each matrix in. The method also obtains the length from the control register, decodes the instruction to obtain the multiplication type, determines the first and second bit widths according to the multiplication type, determines the values ​​of M, N, and K according to the length and the first and second bit widths, and performs matrix multiplication considering the three parameters, the first and second bit widths, and the values ​​of M, N, and K.

The invention relates to a method for the automated inspection of a surface (AS) of a solid object such as, for example, an aircraft surface (AS) (100); the method employing a step of detecting a defect (D) of said surface (AS) represented as a depth map image (S), successive depth profile analyses (DPi) aimed at determining a depth (Pi) for each of said depth profiles (DPi), and then a determination of a "final" depth (P) of a defect from all the depths (Pi) of said profiles. The invention further relates to a system (1) configured to perform the method. Advantageously, it is thus possible to automatically determine the depth of flatness defects in an aircraft surface (AS) (100) with a level of accuracy not yet achieved. Fig. 5

The invention relates to a method for the automated inspection of a surface (AS) of a solid object such as, for example, an aircraft surface (AS) (100); the method employing a step of blurring said surface, represented as a depth-map image, followed by three successive derivation operations applied to said image. The invention further relates to a system configured to perform the method. Advantageously, it is thus possible to automatically detect flatness defects in an aircraft surface (AS) (100) with a level of accuracy not yet achieved. Fig. 1

The invention relates to a method for automatically inspecting a surface (AS) of a solid object, in particular a surface (AS) of an aircraft (100), for example; the method employs a step of detecting a defect (D) in said surface (AS) represented in the form of an image (S), also in the form of a depth map (S), analyses consecutive depth profiles (DPi) intended to determine the depth (Pi) of each of said depth profiles (DPi), which then determines the "final" depth (P) of the defect on the basis of all the depths (Pi) of said profile. The invention also relates to a system (1) configured to perform the method. Advantageously, the non-planar depth of the surface (AS) of the aircraft (100) can thus be automatically determined at a previously unreached level of precision.
