This invention relates generally to a computer-implemented method and system for having anonymous profiling of, and marketing to, anonymous users in a data network, particularly in the Internet. It enables an individual to surf the Internet anonymously as well as enabling third parties to use profiling information to target such anonymous users. The real identity of the individual is never known within the anonymous trust system.

Intelligent Trust Management provides a centralized security facility that gives system components a flexible mechanism for implementing security policies. System components such as applications create a request describing an action that needs to be checked against an appropriate security policy. The request is given to a trust system that determines which policy object applies to the request, and may pass request arguments to the policy. The policy objects include executable code that uses any arguments along with dynamically obtained variable information to make a decision. The decision is returned to the system component, which then operates accordingly. Policy objects may maintain state and interface with the user independent of the system component in order to obtain information to make their decisions. Policy objects may call other policy objects and / or mathematically combine the results of other policy objects to make a decision.

Methods, data structures, and systems by which entities can efficiently discover, extend, validate and establish business relationships over a digital network are disclosed. A transitive trust system can be utilized by any number of interconnected entities in which at least two of the entities are capable of sharing information. One or more entity trust lists contain, for at least two of the entities, at least one characteristic. Each characteristic can, for example, describe or pertain to the actual or perceived dependability, reliability and / or credibility of an entity. The system also includes at least one transactional trust list that contains at least one parameter relative to an exchange between at least two of the entities through at least one degree of separation between the entities. The transactional trust list can, for example, be a listing of any type of parameters that define or describe business exchanges within a particular industry segment. The transactional trust list can also list information about the types of transactional activities that can take place and proxy actions available to cooperating entities. The system retrieves information from the entity trust list and the transactional trust list in order to provide a framework for at least two of the entities to establish relationships with one another.

A trust system and method is disclosed for use in computing devices, particularly portable devices, in which a central Authority shares secrets and sensitive data with users of the respective devices. The central Authority maintains control over how and when shared secrets and data are used. In one embodiment, the secrets and data are protected by hardware-rooted encryption and cryptographic hashing, and can be stored securely in untrusted storage. The problem of transient trust and revocation of data is reduced to that of secure key management and keeping a runtime check of the integrity of the secure storage areas containing these keys (and other secrets). These hardware-protected keys and other secrets can further protect the confidentiality and / or integrity of any amount of other information of arbitrary size (e.g., files, programs, data) by the use of strong encryption and / or keyed-hashing, respectively. In addition to secrets the Authority owns, the system provides access to third party secrets from the computing devices. In one embodiment, the hardware-rooted encryption and hashing each use a single hardware register fabricated as part of the computing device's processor or System-on-Chip (SoC) and protected from external probing. The secret data is protected while in the device even during operating system malfunctions and becomes non-accessible from storage according to various rules, one of the rules being the passage of a certain time period. The use of the keys (or other secrets) can be bound to security policies that cannot be separated from the keys (or other secrets). The Authority is also able to establish remote trust and secure communications to the devices after deployment in the field using a special tamper-resistant hardware register in the device, to enable, disable or update the keys or secrets stored securely by the device.

Federated systems for issuing playback certifications granting access to technically protected content are described. One embodiment of the system includes a registration server connected to a network, a content server connected to the network and to a trusted system, a first device including a non-volatile memory that is connected to the network and a second device including a non-volatile memory that is connected to the network. In addition, the registration server is configured to provide the first device with a first set of activation information in a first format, the first device is configured to store the first set of activation information in non-volatile memory, the registration server is configured to provide the second device with a second set of activation information in a second format, and the second device is configured to store the second set of activation information in non-volatile memory.

Systems, devices and methods are presented for providing controlled use of information stored publicly within the domain name system (DNS). Controlled use is established by storing encrypted data at the DNS servers and establishing trust, in the form of transfer of keying material, with requisite parties. The invention provides backward compatibility with existing DNS servers, in that, it provides for storage of encrypted data in existing resource records. The invention benefits from allowing storage in the DNS to be divided into both public and private classification, such that a user can identify and store certain public information that is available to all parties that have access to the DNS, while other information that has been classified as private is only available to parties which have established a trust.
