An intermediary isolation server receives e-mails and isolates any viral behavior from harming its intended destination. After the intermediary receives an e-mail, it determines that the e-mail has associated executable code, and then identifies the environment in which the e-mail code would be executed if delivered. The intermediary then executes the code by emulating how it would be executed in its ultimate environment. If a viral-like behavior is detected, appropriate action is taken to prevent the execution of the code at its intended destination. The attachment is executed in a contained environment that allows for the contained environment to be easily restarted in a clean state.

In a networked computing environment, a server is equipped to assure the integrity of the service components of a service, including the direct service providing component and one or more supporting components as requested, and a client is equipped to request on behalf of an application in need of the service the integrity assurance. The client is further equipped to either request or accept the service, only upon receiving the integrity assurance. In one embodiment, the request for integrity assurance, and the subsequent conditional request or acceptance of the service is performed in real time.

A method of revealing the device identity of a recipient Bluetooth device. When the recipient device is turned on, it displays the device identity. A user enters the device identity of the recipient device into a sending Bluetooth device in order to establish the initial communication link between the sending and recipient devices. Once the initial communication link is established, the devices are paired. It is no longer necessary to enter the device identity of the recipient device into the sending device in order to establish further communication link. Furthermore, if the recipient device has already been turned on when the user wants to establish the initial communication link, the device identity is displayed when the user sends a message or signal from the sending device to the recipient device.

The installation of a computer program, such as a malware scanner, may be checked to determine whether or not it has not been tampered with using an installation checking computer program to gather characteristics of the installation of the target computer program after the installation checking computer program has first been validated by a separate further computer. The installation characteristics may include operating system registry entries, installed files list, file sizes and file checksums.

One embodiment of the present invention provides a system that uses digital certificates to facilitate enforcing licensing terms for applications that manipulate documents. During operation, the system obtains a credential, wherein the credential includes a private key and a digital certificate containing a corresponding public key. This digital certificate also contains a profile specifying allowed operations which can be performed on documents signed with the credential. Next, the system digitally signs a document using the credential, so that the resulting signed document is signed with the private key and includes a copy of the digital certificate with the profile specifying the allowed operations. The certificate issuer can subsequently revoke the digital certificate (which effectively revokes the license) if terms of a license agreement associated with the digital certificate are violated.

A method and apparatus for automatic user authentication are described. The method includes receiving information at a device, the device including a credential container; storing the information at the credential container and performing cryptographic calculations on the received information and providing the encrypted information upon request.

An anti malware scanner for files is provided with means for processing script and macro files and flagging them as suspect or not based upon an automated analysis of source code in the file. This analysis involves separating the program source into groups of parts such as comment, variable names and routine names, eliminating duplicates and performing a character frequency distribution analysis of the resulting strings. The system may include an exception list to omit flagging a file as suspect if it is on the exception list.

A system and a method are disclosed for a content delivery system that enable system-independent, remote storing of digital content on any number of a user's devices. The system and method enable a user to designate a digital content item appearing in a web page for storage, as well as a specific, separate device on which to store the content item. The digital content item is not restricted to being viewed or accessed within the content delivery system, but rather the content delivery system enables remote storing of digital content across multiple different systems, from multiple different content sources, for viewing on multiple different devices for any given user.

The present invention utilizes single composite bus and several active joint-boxes to detect lots of signals of composite sensor containing several physical quantities sensing devices and internal-mounted modulator. It can obtain rich information, and can make voltage and current conversion in the active joint-boxes so as to can raise transmission distance, improve frequency response, resist interference and make treatment for resisting pollution in the joint-box. It has excellent effect in the tests of vehicle fault diagnosis system.
