A system allows a reliable and efficient identity management that can, with full interoperability, accommodate to various requirements of participants. For that a system is presented for providing an identity-related information about a user to a requesting entity. The method includes a location-request step initiated by the requesting entity for requesting from a client application a location information that corresponds to a location entity possessing the identity-related information, a redirecting step for connecting the client application to the location entity in order to instruct the location entity to transfer the identity-related information to the requesting entity, and an acquiring step for obtaining the identity-related information. The acquiring step includes a contact step wherein the location entity contacts the requesting entity, a request step wherein the requesting entity requests the identity-related information, and a response step wherein the requesting entity receives the identity-related information from the location entity.

A computer-implemented system and method for protecting a memory are provided. The system includes a memory section with privileged and non-privileged sections, a host gateway (HG) to generate a capability credential, a device controller (DC) to append the credential to data transmitted to the memory, and at least one IO device enabled to do direct memory access (DMA) transactions with the memory.

Memory protection and security using credentials

Systems, apparatus and methods for privacy-protecting integrity attestation of a computing platform. An example method for privacy-protecting integrity attestation of a computing platform (P) has a trusted platform module (TPM), and comprises the following steps. First, the computing platform (P) receives configuration values (PCRPCRn). Then, by means of the trusted platform module (TPM), a configuration value (PCRp) is determined which depends on the configuration of the computing platform (P). In a further step the configuration value (PCRp) is signed by means of the trusted platform module. Finally, in the event that the configuration value (PCRp) is one of the received configuration values (PCRPCRn), the computing platform (P) proves to a verifier (V) that it knows the signature (sign(PCRp)) on one of the received configuration values (PCRPCRn).

Software license management systems are provided in which a license to use a software product is represented by a data token. The systems have a software controller for controlling use of the software product at a user device, and a license management server for communicating with the software controller via a data communications network. The software controller allows use of the software product at the user device substantially only during a use period associated with a current data token supplied to the software controller by the license management server. An exchange token can be supplied to another, similar software controller when necessary to transfer the license, e.g. in the event of a breakdown. The software controller is adapted to supply either the current data token, or the exchange token, to the license management server to be exchanged for a new data token.

In a computer, a first set of object classes are provided representing active entities in an information-handling process and a second set of object classes are provided representing data and rules in the information-handling process. At least one object class has rules associated with data. The above-mentioned objects are used in constructing a model of an information-handling process, and to provide an output that identifies at least one way in which the information-handling process could be improved. One aspect is a method for handling personally identifiable information. Another aspect is a system for executing the method of the present invention. A third aspect is as a set of instructions on a computer-usable medium, or resident in a computer system, for executing the method of the present invention.

Using an object model to improve handling of personally identifiable information

The invention provides a data network, systems and methods for checking nodes of a data network that are used for detecting whether a privacy policy concerning an information is maintained. The information comprises a mark corresponding to the privacy policy. The mark defines the storage place or the accessing paths or the transferring paths of the information. The mark is automatically searchable. The mark is searched, analyzed and checked as to whether the privacy policy is maintained. The advantage of the system is that vulnerabilities of systems for protecting confidential information may be detected a long time before an attack on the confidential information occurs.

Data network and method for checking nodes of a data network

Method, system, and storage medium for reducing or minimizing access to sensitive information. A method includes identifying processes and data associated with a computer system and classifying each of the data as one of either sensitive information or non-sensitive information. The sensitive information includes at least one of: data that is personal to an individual, confidential data, and data that is legally subject to conditions of restricted use. For each of the processes the method includes selecting a process and a sensitive data item, modifying the sensitive data item, analyzing the behavior of at least the selected process, and preventing access of the sensitive data item by the selected process if, as a result of the analyzing, the sensitive data item is determined not to be needed by the selected process.

Reducing access to sensitive information

Method and device for verifying the security of a computing platform. In the method for verifying the security of a computing platform a verification machine is first transmitting a verification request via an integrity verification component to the platform. Then the platform is generating by means of a trusted platform module a verification result depending on binaries loaded on the platform, and is transmitting it to the integrity verification component. Afterwards, the integrity verification component is determining with the received verification result the security properties of the platform and transmits them to the verification machine. Finally, the verification machine is determining whether the determined security properties comply with desired security properties.

A computer-implemented method for protecting a memory is provided. The method includes responsive to a direct memory access (DMA) request received from a consumer for a transaction of data from an IO device to the memory, the request including an IO command and a capability (CAP), generating a cryptographically signed capability (CAPB), forming a credential from CAP and CAPB, appending the credential to the IO command, configuring the IO device according to the credential and the IO command, transmitting the data from the IO device to the memory and prior to allowing execution of the DMA, authenticating that the credential is valid, further includes regenerating CAPB from a key available to an authenticating entity and from the CAP (included in CAPB) and verifying that the memory region information described in the cryptographically signed capability is the same as the requested region that was originally created, and that the cryptographically signed capability encompasses the IO command.

The invention entails identifying the parties involved in a process of handling personally identifiable information; identifying the data involved in said process; classifying the data; expressing each relationship between each pair of said parties in terms of a privacy agreement; and representing the parties, data, and privacy agreements graphically in one or more privacy agreement relationship diagrams. The invention has the advantage of identifying opportunities to reduce privacy-related risks, including identifying unnecessary exchanges of data, for possible elimination, and identifying opportunities to transform data into a less sensitive form. Privacy agreements are based on a limited set of privacy-related actions: access, disclose, release, notify, utilize, update, withdrawConsent, giveConsent, delete, anonymize, depersonalize, and repersonalize. One aspect of the present invention is a method for improving the handling of personally identifiable information. Another aspect of the present invention is a system for executing the method of the present invention. A third aspect of the present invention is as a set of instructions on a computer-usable medium, or resident in a computer system, for executing the method of the present invention.
