The invention is directed to just-in-time (JIT) retrieval of directory information to reduce network traffic and load on directory servers and/or data sources by requesting only the information that is currently needed from the directory server. In the invention, a request handler operating with the directory server provides this capability. Specifically, the request handler and directory server are configured to receive a request for directory information from a client and to determine a location corresponding to a set of current attribute values for responding to the request. The request handler retrieves the set of current attribute values from at least one of the following: the directory server and an external source. A set of current attributes is returned to the client from the directory server. The request handler propagates information in a JIT manner so that only the information that will be currently used by the client is propagated across the network.

Integrated just-in-time synchronization

The present invention may comprise a system and method for a Virtual Attribute Federation System (VAFS) and may be composed of a Virtual Attribute Federation Manager (VAFM) and a system of Virtual Attribute Enabled Directories (VAED) modified to accept federation of virtual attributes. The VAFM produces signed and trusted calculation methods and coordinates a synchronized dispersal of these methods to the VAEDs. The VAEDs may have local mappings which allow for federation-time configuration of the calculation methods.

Embodiments of the present invention include a computer system and computer program product for implementing encryption of data. A computer system determines that a first data field of a plurality of data fields of a web form requires encryption. The computer system tags the first data field with one or more HTML encryption tags. The computer system displays the web form to a user. The computer system receives user input, wherein at least a portion of the user input is contained in the first data field of the web form. The computer system encrypts the first data field on a first computer, wherein a first user specific encryption key is associated with at least the first data field. The computer system inserts the encrypted first data field into at least one record stored on a second computer.

Data encryption at the client and server level

Approaches for using the historical party reputation data to calculate an access decision rating are provided. Specifically, one or more approaches provide a method, including: collecting reputation information of a first user that is requesting access to one or more assets, the reputation information based on at least an association of the first user with an organization and an association of the first user with one or more other users associated with one or more other organizations; storing the requester's reputation information; determining a change in the requester's reputation information, wherein the change comprises at least one of: the first user forming a new association with another organization, and the first user forming a new association with a second user, wherein the second user is affiliated with another organization; and causing an access decision rating to be calculated based upon the determined change in the requester's reputation information.

Gathering, storing and using reputation information

Embodiments of the present invention disclose a method, system, and computer program product for implementing user specific encryption in a database system. A computer receives a query statement including a user specific key and data, the data including data needing encryption and non-encrypted data. The computer encrypts the data needing encryption using the user specific key. The computer inserts both the encrypted data and the non-encrypted data into a table row in a database. The computer creates a hash of the user specific key, and stores the hash of the user specific key in the table row with the data.

Field level database encryption using a transient key

The invention is directed to just-in-time (JIT) retrieval of directory information to reduce network traffic and load on directory servers and/or data sources by requesting only the information that is currently needed from the directory server. In the invention, a wrapper operating with a directory server and an application programming interface (API) provides this capability. The wrapper is configured to receive a request from a client and to determine a location corresponding to a set of current attribute values for responding to the request. The wrapper retrieves the set of current attribute values in a JIT manner from at least one of the following: the directory server and an external source. A set of current attributes is returned to the client from the wrapper. By propagating information in a JIT manner, only the information that will be currently used is propagated across the network.

Approaches for providing reputation based access control are provided. Specifically, at least one approach includes: identifying a requesting subject requesting access to a controlled resource; retrieving a reputation of the subject stored as a virtual attribute in a reputation-based access control database, the reputation comprising a value for skill for operating with the requested controlled resource; determining whether the subject is a known security risk; modifying a reputation of the subject and an associate in the case that a security risk of the subject meets a threshold; modifying the reputation of the subject based on at least one of: peer feedback and expert opinion, in the case that the subject is not a known security risk; retrieving a policy of the requested controlled resource; determining if the reputation of the subject meets the policy, and if so, allowing the subject access to the resource, and if not, denying the access.

Reputation based access control

An approach for connecting the inputs and the outputs of multiple services in such a way that the entire transaction can be tracked from beginning to end and from service to service is provided. The pipeline architecture of the present invention passes information through a sequence of nodes, each node providing some processing or filtering before passing information to the next node in the pipe. A transaction's token passes down a pipe of services. The pipe can have forks and branches, so a transaction's token is passed from node to node carrying messages from one node to another. The overall transactional information is not lost from service to service; instead it is carried up and down the length of the pipeline. As the transaction's token is passed up and down the pipeline, its history passes with it. The pipe links a chain of nodes connected end-to-end.

Transactional service pipeline

Approaches for providing reputation based access control are provided. Specifically, at least one approaches includes: identifying a requesting subject that is requesting access to a controlled resource; retrieving the requesting subject's reputation stored as a virtual attribute in a reputation-based access control database, wherein the requesting subject's reputation comprises a value for skill for operating with the requested controlled resource, and wherein the requesting subject's reputation is modified following an indication from a peer of the requesting subject that the requesting subject's value for skill is diminished; retrieving the requested controlled resource's policy; determining if the requesting subject's reputation meets the requested controlled resource's policy; if the requesting subject's reputation meets the requested controlled resource's policy, allowing the requesting subject access to the requested controlled resource; and if the requesting subject's reputation does not meet the requested controlled resource's policy, denying the requesting subject access to the requested controlled resource.

A system and method for creates, maintains and monitors individuals, organizations and artifacts relating to the same over time with respect to pedigree and reputation, security and reliability. One aspect of the present invention provides for a method and a system for collecting and maintaining historical party reputation data. Another aspect of the present invention provides for a method and a system for assessing an access decision to the historical party reputation data to a person after the person's reputation has changed.

Data system forensics system and method

A computer identifies an available task assignment, which is location independent for completion, and determines if an assignee is available to perform work on the task assignment. The assignee's availability is based in part on information received from a mobile device of the assignee. When a change in availability is determined by the mobile device, the mobile device sends the assignee's availability information to the computer, indicating the change. If the computer determines that the assignee is available, then the computer sends the task assignment information to the mobile device of the assignee. If the computer determines the assignee is not available, then the computer sends the task assignment information to a delegate of the assignee. The computer monitors the completion of a task assignment. If the computer determines that a task assignment has not, or can not, be timely completed, then the task assignment is reassigned to a delegate.

System for assignment routing, delegation and reassignment

The reputation based access control system of the present invention allows or denies access to a requested controlled resource to a requesting subject based upon predetermined associations between the resource and security contexts to determine the subject's reputation in those contexts. The reputation based access control system utilizes an authentication system (biometric, challenge/response, etc.) to identify a subject. Once the identity is determined, a resource to be accessed is determined by a reputation based access control unit. The system interfaces with a reputation assessment system to gauge the subject's reputation in these contexts. If the subject's reputation meets the predetermined limits for reputation in those contexts for that resource, the subject is allowed access to the resource. Otherwise access is denied and the proper agents are notified.

The invention is directed to off-peak and just-in-time (JIT) retrieval of directory information to reduce network traffic and load on directory servers and/or data sources by requesting only the information that is currently needed from the directory server, while subsequently updating the directory information during an off-peak period in the case that the directory information retrieved in a JIT manner is outdated. In these embodiments, a hybrid integrator operable with an integration directory capable of retrieving directory information in a JIT manner provides this functionality.
