Abstractions and automation for enhanced sharing and collaboration
The present invention provides methods for using abstractions of people, including dynamic and static groups of people, to enhance the efficiency of the specification and automation of policies for sharing information between users with a “need-to-know.” An instance of the present invention can also provide these users information based on a “time-to-know.” By providing access to information based on group affiliation and properties of the content of the information, the present invention maintains optimal information privacy while minimizing encumbrances to sharing data with appropriate users and even at appropriate times. The present invention can be integrated with other communication technologies to facilitate access to information in a time appropriate manner. Other instances of the present invention employ automated and semi-automated, mixed-initiative techniques, to make information-sharing decisions. Additional instances of the present invention include the employment of machine-learning techniques to facilitate construction of access policies from the actions or profile of a single user or a community of users, including the construction of automated sharing agents that work in an automated or mixed-initiative manner to respond to real-time requests for information.

Extensible framework for system security state reporting and remediation
A security health reporting system provides an application program interface (API) for use by independent software vendors (ISVs) to extend the security health reporting capabilities of the security health reporting system. An ISV security solution can register with the security health reporting system, create a schema that describes a new security class, and use the API to publish an instance of the schema for the new security class with the security health reporting system. When an instance of a schema for a new security class is published, the security health reporting system creates the new security class, and recognizes the definition for the security class within the security health reporting system. Registered ISV security solutions can then use the published schema to report their health statuses for the new security class.
Accomodating fragmentation with deterministic packet marking
The deterministic packet marking (DPM) method is based on marking packets with the partial address information of ingress interface only. The attack victim is able to recover the complete address(es) information after receiving several packets from a particular attacking host or hosts. The full path is not really essential for the traceback since it can be different for different packets for different reasons. In order to deal with fragmentation, it is required that the ID field (as well as some other fields) of all the fragments in a given series is the same. DPM randomly selects the marks from the pool, which is created at startup. The mark completely occupies the ID field in the IP packet header, as well as Reserved Flag. Since every single packet passing through the DPM-enabled interface is marked, the ID field of all the fragments of a series are ensured to be the same. By allowing DPM to suspend randomness in selecting the marks for the fragments of a series, all fragments are ensured to have the same ID. This ID would be different from the one originally set by the origin of the packet, but this would not make a difference for the reassembly process.

If the trust level is not high enough, then questions are sent to the user and the user's answers are evaluated and access is granted or denied based on the trust level and answers. The user's profile is updated to reflect the access attempt.

Testing functional boundary logic at asynchronous clock boundaries of an integrated circuit device
Mechanisms for testing functional boundary logic at an asynchronous clock boundary of an integrated circuit device are provided. With these mechanisms, each clock domain has its own scan paths that do not cross domain boundaries. By eliminating the scanning across the boundaries, the requirement to have two clock grids in the asynchronously clocked domains may be eliminated. As a result, circuit area and design time with regard to the clock distribution design are reduced. In addition, removing the second clock grid, i.e. the high speed core or system clock, in the asynchronously clocked domains removes the requirement to have a multiplexing scheme for selection of clocking signals in the asynchronous domain. In addition to the above, the system and method provide boundary built-in-self-test logic for testing the functional crossing logic of boundaries between the clock domains in a functional mode of operation.
Scan testable register file
Memory compiler engineers often focus on the efficient implementation of the largest possible memory configurations for each memory type. The overhead of test and control circuitry within memory implementations is usually amortized across a large number of storage bits. Unfortunately, test structures generally do not scale down with decreasing memory sizes, creating a large area penalty for a design with numerous small memories. One solution is a scannable register file (SRF) architecture using scannable latch bit-cells laid out using a standard cell layout/power template. All sub-cells can be placed in standard cell rows and utilize standard cell power straps. Non-SRF standard cells can be abutted on all sides, placement keep-out regions are not needed. Metal utilization is usually limited to first three metallization layers. The bit-cell is much larger than standard compiled memory bit cells, but has no overhead beyond address decode, word-line drivers, and read-write data latches.

Facilitated use of column and field data for field record universe in a knowledge store
Typically, field names are saved separately from tables as metadata in modern databases. Databases did not traditionally get built into interlocking trees datastores that recorded the data as events. However, in cases where one may wish to do that, thus avoiding the need for saving separate metadata from the table data of the data base, a need was found to establish an identity for particular columns or fields when working with databases or sources of data that provide table data in field/record format. So, to build interlocking trees datastores from such records a mechanism to record such data was created, adding a column ID, preferably to each field within each record or sequence that is to be recorded. Putting the column ID or identifier is inserted into the record during particlization between each column variable. In preferred embodiments a delimiter was included between the column ID or field name and the field variable. Appropriate hardware and software systems were employed to implement the invention.

Information management system
An information management system is described comprising one or more workstations running applications to allow a user of the workstation to connect to a network, such as the Internet. Each application has an analyzer, which monitors transmission data that the application is about to transmit to the network or about to receive from the network and which determines an appropriate action to take regarding that transmission data. Such actions may be extracting data from the transmission data, such as passwords and usernames, digital certificates or eCommerce transaction details for storage in a database; ensuring that the transmission data is transmitted at an encryption strength appropriate to the contents of the transmission data; determining whether a check needs to be made as to whether a digital certificate received in transmission data is in force, and determining whether a transaction about to be made by a user of one of the workstations needs third party approval before it is made. The analyzer may consult a policy data containing a policy to govern the workstations in order to make its determination. The information management system provides many advantages in the eCommerce environment to on-line trading companies, who may benefit by being able to regulate the transactions made by their staff according to their instructions in a policy data, automatically maintain records of passwords and business conducted on-line, avoid paying for unnecessary checks on the validity of digital certificates and ensure that transmissions of data made by their staff are always protected at an agreed strength of encryption.
