201results about How to "Avoid storage problems" patented technology

A system for electronic file collaboration among multiple users is implemented using command messages transmitted on dedicated network channels established between conference participants in a peer-to-peer architecture with total autonomy from a central server. The system employs owner-in-control methodology to allow direct transmission of copies of documents among participants by permission, and to prevent storage of copies of documents used in a conference by participants. Mark-ups, additions, and other actions occurring on a conference document can only be saved by the document owner. An advanced viewer engine is provided for reading, displaying and manipulating electronic data in texts, tables, vectors and 3D model formats, as well as common raster images. A proxy module allows data transmitted through IPFW routers or firewall devices with sufficient authentications and security measures.

One of the various aspects of the invention is related to suggesting various techniques for improving the tamper-resistibility of hardware. The tamper-resistant hardware may be advantageously used in a transaction system that provides the off-line transaction protocol. Amongst these techniques for improving the tamper-resistibility are trusted bootstrapping by means of secure software entity modules, a new use of hardware providing a Physical Unclonable Function, and the use of a configuration fingerprint of a FPGA used within the tamper-resistant hardware.

The present invention provides a data processing apparatus and method for managing access to a memory within the data processing apparatus. The data processing apparatus comprises a processor operable in a plurality of modes and a plurality of domains, said plurality of domains comprising a secure domain and a non-secure domain, said plurality of modes including at least one non-secure mode being a mode in the non-secure domain and at least one secure mode being a mode in the secure domain, said processor being operable such that when executing a program in a secure mode said program has access to secure data which is not accessible when said processor is operating in a non-secure mode. Further, a memory is provided for storing data required by the processor, and consists of secure memory for storing secure data and non-secure memory for storing non-secure data. The memory further contains a non-secure table and a secure table, the non-secure table being within the non-secure memory and arranged to contain for each of a number of first memory regions an associated descriptor, and the secure table being within the secure memory and arranged to contain for each of a number of second memory regions an associated descriptor. When access to an item of data in the memory is required by the processor, the processor issues a memory access request, and a memory management unit is provided to perform one or more predetermined access control functions to control issuance of the memory access request to the memory. The memory management unit comprises an internal storage unit operable to store descriptors retrieved by the memory management unit from either the non-secure table or the secure table, and in accordance with the present invention the internal storage unit comprises a flag associated with each descriptor stored within the internal storage unit to identify whether that descriptor is from the non-secure table or the secure table. By this approach, when the processor is operating in a non-secure mode, the memory management unit is operable to perform the predetermined access control functions for the memory access request with reference to access control information derived from the descriptors in the internal storage unit retrieved from the non-secure table. In contrast, when the processor is operating in a secure mode, the memory management unit is operable to perform the predetermined access control functions for the memory access request with reference to access control information derived from the descriptors in the internal storage unit retrieved from the secure table. This approach enables different descriptors to be used for the control of accesses to memory in either the secure domain or the non-secure domain, whilst enabling such different descriptors to co-exist within the memory management unit's internal storage unit, thereby avoiding the requirement to flush the contents of such an internal storage unit when the operation of the processor changes from the secure domain to the non-secure domain, or vice versa.

A receiver for receiving a stream of symbols clocked at a first rate, and providing the symbols at a second clock rate uses two buffers. Incoming symbols are written to a first dual clock buffer at the first rate, and read from the first and second buffer, at the second rate. Underflow of the first buffer is signaled to the second buffer, thereby avoiding the need to insert defined clock compensation symbols at the second rate. Symbols received at the second buffer while underflow is signaled may be ignored. Conveniently, the second buffer may also be used to align symbol data across multiple symbol streams using periodic alignment symbols. An exemplary embodiment conforms to the PCI Express standard.

Described herein are formulations of active pharmaceutical ingredients, where the active pharmaceutical ingredients or drugs are included in a solid suspension with one or more solid additives. The formulations described herein are useful for formulating any drug or active pharmaceutical ingredient, including those that have limited solubility in organic and/or aqueous solvent systems.

According to a conventional technique, in the case where a program is stored into a non-volatile memory once and then activated, authentication of the program is performed immediately before such activation. However, calculations such as decryption of encrypted values are required before the activation of the program starts, which causes the problem that responsiveness is decreased in proportion to the time required for calculations. In order to solve this problem, authentication of a program is performed immediately before such program is stored, so that no authentication is performed or only a part of the authentication is performed to verify the validity of certificates at program activation time.

A checkpointing method for creating a file representing a restorable state of a virtual machine in a computing system, comprising identifying processes executing within the virtual machine that may store confidential data, and marking memory pages and files that potentially contain data stored by the identified processes; or providing an application programming interface for marking memory regions and files within the virtual machine that contain confidential data stored by processes; and creating a checkpoint file, by capturing memory pages and files representing a current state of the computing system, which excludes information from all of the marked memory pages and files.

When executing a licensing management application, data indicative of licensing privileges of a software application for simultaneous execution on a subset of a plurality of computers are received from a licensor of the software application. The data indicative of licensing privileges comprise data indicative of a licensing key. For each of a plurality of users a peripheral licensing device is provided and the data indicative of a licensing key are then stored in memory thereof. Data indicative of a total number of users—equal to a number of the subset—are determined and provided to the licensor, or storage of the licensing key is prevented, when the total number is greater than a predetermined number of the subset. After execution of the licensing management application and provision of each of the users with a respective peripheral licensing device, each of the users is enabled to execute the software application by interfacing the peripheral licensing device with one of the computers, after which the data indicative of a licensing key are retrieved and the software application is executed.
