In a method and a device for partial encryption and progressive transmission of images, a first section of the image file is compressed at reduced quality without decryption, and a second section of the image file is encrypted. Users having access to appropriate decryption keywords can decrypt this second section. The first section together with the decrypted second section can then be viewed as a full quality image. The storage space required for storing the first and section together is essentially the same as the storage space required for storing the unencrypted full quality image. By using the method and device as described herein storage and bandwidth requirements for partially encrypted images is reduced. Furthermore, object based composition and processing of encrypted objects are facilitated, and ROIs can be encrypted. Also, the shape of a ROI can be encrypted and the original object can be decrypted and restored in the compressed domain.

A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. The graphics processor includes an embedded frame buffer for storing frame data prior to sending the frame data to an external location, such as main memory. A copy pipeline is provided which converts the data from one format to another format prior to writing the data to the external location. The conversion may be from one RGB color format to another RGB color format, from one YUV format to another YUV format, from an RGB color format to a YUV color format, or from a YUV color format to an RGB color format. The formatted data is either transferred to a display buffer, for use by the video interface, or to a texture buffer, for use as a texture by the graphics pipeline in a subsequent rendering process.

A training model for malware detection is developed using common substrings extracted from known malware samples. The probability of each substring occurring within a malware family is determined and a decision tree is constructed using the substrings. An enterprise server receives indications from client machines that a particular file is suspected of being malware. The suspect file is retrieved and the decision tree is walked using the suspect file. A leaf node is reached that identifies a particular common substring, a byte offset within the suspect file at which it is likely that the common substring begins, and a probability distribution that the common substring appears in a number of malware families. A hash value of the common substring is compared (exact or approximate) against the corresponding substring in the suspect file. If positive, a result is returned to the enterprise server indicating the probability that the suspect file is a member of a particular malware family.

A memory system and methods of operating the same that drastically increase the efficiency in memory use and allocation in graphics systems. In a graphics system using a tiled architecture, instead of pre-allocating a fixed amount of memory for each tile, the invention dynamically allocates varying amounts of memory per tile depending on the demand. In one embodiment all or a portion of the available memory is divided into smaller pages that are preferably equal in size. Memory allocation is done by page based on the amount of memory required for a given tile.

A document imaging system detects skew and/or size of a document. In one embodiment, a document imaging system generates scanning signals representing the documents, analyxes the scanning signals to detect one more edges of the document before the entire lenght of the document is scanned, establishes a skew angle between the detected edges and a reference orientation, and modifies the scanning signals to compensate for skew while the document is being scanned. In another embodiment, a document imaging system detects one or more edges of a document, defines a polygon having sides substantially congruent with the detected edges, and establishes the size of the document in response to the polygon.

The present invention determines the adopting ratio (weight coefficient) between the high image quality processing using the tensor projection method and the high image quality processing using another method according to the degree of deviation of the input condition of the input image, and combines these processes as appropriate. This allows a satisfactory reconstruction image to be acquired even in a case of deviation from the input condition, and avoids deterioration of the high quality image due to deterioration of the reconstruction image by the projective operation.

The present invention is related to systems and methods that parse and/or translate inbound messages into outbound messages such that disparate computer systems can communicate intelligibly. In one embodiment, a system recursively parses the inbound message such that relatively fewer outbound message structure definitions are required and advantageously decreases the usage of resources by the system. Further, one system in accordance with the present invention allows an operator to configure the identity of a delimiter in the inbound message. The delimiter can span multiple characters and includes the logical inverse of a set of delimiters. The outbound message can be accessed at nodes within a hierarchy, as well as at leaves. Thus, a user need not know the precise location of data within the outbound message. A set of updating rules further permits the updating of an outbound message without having to re-parse an entire inbound message.

Menus are created that facilitate access to data in a menu database. Preferably, the menus include a plurality of menus items laid out so as to duplicate the spatial organization of keys on a numeric keypad, such that a one-to-one relationship exists between the keys on the keypad and the menu items. The amount of memory required to store database records relating to individual menus is reduced, because a menu template provides general formatting information. Thus, database records need not include formatting details. When a menu is required, a menu template modifier uses the menu template and the corresponding database record to generate the desired menu. The menus are employed for accessing data in the menu database. An edit function is provided in the menu template modifier to enable custom menus to be developed and modified.

A scalable encoding apparatus, a scalable decoding apparatus and the like are disclosed which can achieve a band scalable LSP encoding that exhibits both a high quantization efficiency and a high performance. In these apparatuses, a narrow band-to-wide band converting part (200) receives and converts a quantized narrow band LSP to a wide band, and then outputs the quantized narrow band LSP as converted (i.e., a converted wide band LSP parameter) to an LSP-to-LPC converting part (800). The LSP-to-LPC converting part (800) converts the quantized narrow band LSP as converted to a linear prediction coefficient and then outputs it to a pre-emphasizing part (801). The pre-emphasizing part (801) calculates and outputs the pre-emphasized linear prediction coefficient to an LPC-to-LSP converting part (802). The LPC-to-LSP converting part (802) converts the pre-emphasized linear prediction coefficient to a pre-emphasized quantized narrow band LSP as wide band converted, and then outputs it to a prediction quantizing part (803).

It is possible to express a tree-type data structure so as to effectively trace the relationship between data in the tree-type data structure (for example, parent-child, ancestor, descendant, brothers, generations). In the tree-type data structure, for each of non root nodes which are the nodes excluding the root node, their parent nodes are correlated so that the parent-child relationship between the nodes is expressed by using “child->parent” relationship. Accordingly, by specifying a child node, it is possible to promptly specify the only one parent node corresponding to the child node.
