A first identifier associated with a first routine is received as input. A determination of whether a first list includes the first identifier is made. In response to the determination, a first action is performed in the event the first list includes the first identifier. A second action that is different from the first action is performed in the event the first list does not include the first identifier.

Managing and classifying states

Enrolling a device identity is disclosed. A determination is made as to whether one or more areas of a storage device has a sufficient number of faults. If an insufficient number of faults is present, additional faults are generated. Verifying a device identity is also disclosed. A fingerprint based on the presence of one or more permanent faults in a storage device is received. The received fingerprint is compared with one or more stored fingerprints to determine an identity of the device.

Managing device identity

The auditing of a device that includes a physical memory is disclosed. One or more hardware parameters that correspond to a hardware configuration is received. Initialization information is also received. The physical memory is selectively read and at least one result is determined. The result is provided to a verifier.

Auditing a device

The auditing of a device that includes a physical memory is disclosed. One or more hardware parameters that correspond to a hardware configuration is received. Initialization information is also received. The physical memory is selectively written in accordance with a function. The physical memory is selectively read and at least one result is determined. The result is provided to a verifier.

An image representation format for representing a digital image comprises: image information stored as a bitstream representing sequential image blocks, each block comprising one or more components, each component comprising one or more data units and each data unit being represented as a Huffman-coded stream of coefficients of basis functions, wherein a zeroth order coefficient is represented as a difference to the previous zeroth order coefficient of the corresponding component, and a block information table, which comprises: indicators to the first coefficient of a specified order of each image block in said bitstream, information indicating the number of bits in the bitstream between adjacent coefficients of said specified order of the image block, and the zeroth order coefficient of at least the first data unit of each component, said zeroth order coefficient being represented in a non-differential form.

Method for processing a digital image

Auditing a device is disclosed. One or more hardware parameters that correspond to a hardware configuration is received. A sequence of modifications to the physical memory is performed. Results are provided to a verifier. Optionally, once it is determined that no evasive software is active in the physical memory, a scan is performed.

The invention relates to a method for enhancing color resolution and particularly for obtaining bit resolution in a display using a bits per pixel system frame buffer. The invention uses logic to create intermediate pixel values between bpp color values. The invention proposes to store the image in the system frame buffer always with a fixed number of bits and using Error Diffusion Dither. Then a postprocessing filter is provided to provide the enhanced color resolution using a greater number of bits per pixel as accepted by the display means. The invention also relates to a device exploiting the method.

Method for processing a digital image and image representation format

An image representation format for representing a digital image including image information stored as a bitstream representing sequential image blocks, each block comprising one or more components, each component comprising one or more data units and each data unit being represented as a Huffman-coded stream of coefficients of basis functions, wherein a zeroth order coefficient is represented as a difference to the previous zeroth order coefficient of the corresponding component, and a block information table, which comprises: indicators to the first coefficient of a specified order of each image block in the bitstream, information indicating the number of bits in the bitstream between adjacent coefficients of the specified order of the image block, and the zeroth order coefficient of at least the first data unit of each component, the zeroth order coefficient being represented in a non-differential form.

The invention relates to a method for determining where a next data unit of a bit stream of an image starts. The method comprises analyzing a first part of a bit stream entry, the bit stream entry being included in a data unit, determining from said analysis of the first part of the bit stream entry the number of bits used by the bit stream entry, skipping the number of bits determined to be used by the bit stream entry, and determining if an end of block symbol has been reached, if an end of block symbol has not been reached then a new bit stream entry starting at the end of the previous is analyzed.
