| 20110277036 | Policy Determined Accuracy of Transmitted Information - Systems and methods for controlling accuracy of transmitted information are described. A package is assembled based on a numerical value, such as a measurement, and one or more policies associated with the sender. When the package is received by a receiver, it is unpacked to yield a second value representing the numerical value and having a reduced accuracy with respect to the first value. The accuracy reduction depends on policies associated with the receiver and/or the sender. Examples of numerical values in different applications include geo-location data, medical data, and financial data. | 11-10-2011 |
| 20110246782 | Data Protection Systems and Methods - Systems and methods are provided for protecting electronic content from the time it is packaged through the time it is experienced by an end user. Protection against content misuse is accomplished using a combination of encryption, watermark screening, detection of invalid content processing software and hardware, and/or detection of invalid content flows. Encryption protects the secrecy of content while it is being transferred or stored. Watermark screening protects against the unauthorized use of content. Watermark screening is provided by invoking a filter module to examine content for the presence of a watermark before the content is delivered to output hardware or software. The filter module is operable to prevent delivery of the content to the output hardware or software if it detects a predefined protection mark. Invalid content processing software is detected by a monitoring mechanism that validates the software involved in processing protected electronic content. Invalid content flows can be detected by scanning the information passed across system interfaces for the attempted transfer of bit patterns that were released from an application and/or a piece of content management software. | 10-06-2011 |
| 20100299522 | Content Sharing Systems and Methods - Systems and methods are described for peer-to-peer sharing of electronic content. In one embodiment, if a license associated with a content item permits a sharing peer to share the content item with a receiving peer, the sharing peer rebinds a cryptographic key associated with the content item to the receiving peer and generates a sharing license for the content item. The sharing peer sends the sharing license and the content item to the receiving peer for consumption. | 11-25-2010 |
| 20100293058 | Ad Selection Systems and Methods - Systems and methods are described for dynamically selecting an advertisement for presentation to an end user in combination with an electronic content item. In one embodiment, a control associated with the electronic content item is evaluated to determine whether the advertisement is permitted to be presented in combination with the electronic content item. A control associated with the advertisement is also evaluated to determine an amount that the provider of the advertisement is willing to pay to have the advertisement presented to the end user in combination with the electronic content item. If this amount is greater than the amount bid by other advertisements, then the advertisement and the content item are presented together to the end user. | 11-18-2010 |
| 20100293050 | Dynamic, Local Targeted Advertising Systems and Methods - Systems and methods are described for targeting advertisements to a user of an electronic device. In one embodiment, the user's device receives multiple advertisements and at least one content item. Using a control associated with the content item and controls associated with the advertisements, the user's system dynamically determines the optimum advertisements to render with the content item. Information about the advertisements that were selected can be sent to a remote party to facilitate payment by the provider of the advertisements to the provider of the content. | 11-18-2010 |
| 20100228999 | Trusted Storage Systems and Methods - Systems and methods are disclosed for providing a trusted database system that leverages a small amount of trusted storage to secure a larger amount of untrusted storage. Data are encrypted and validated to prevent unauthorized modification or access. Encryption and hashing are integrated with a low-level data model in which data and meta-data are secured uniformly. Synergies between data validation and log-structured storage are exploited. | 09-09-2010 |
| 20100223672 | Systems and Methods for Managing and Protecting Electronic Content and Applications - Systems and methods are disclosed for managing and protecting electronic content and applications. Applications, content, and/or users can be given credentials by one or more credentialing authorities upon satisfaction of a set of requirements. Rights management software/hardware is used to attach and detect these credentials, and to enforce rules that indicate how content and applications may be used if certain credentials are present or absent. In one embodiment an application may condition access to a piece of electronic content upon the content's possession of a credential from a first entity, while the content may condition access upon the application's possession of a credential from a second entity and/or the user's possession of a credential from a third entity. Use of credentials in this manner enables a wide variety of relatively complex and flexible control arrangements to be put in place and enforced with relatively simple rights management technology. | 09-02-2010 |
| 20100030869 | SYSTEMS AND METHODS FOR MANAGING THE DISTRIBUTION OF ELECTRONIC CONTENT - The present invention provides systems and methods for transferring electronic information from one location to another such that only one original work exists at a given time. The methods and systems of the present invention allow distribution of originals without requiring a registration authority or other entity to vouch for what constitutes an “original” piece of information, thus reducing (or eliminating entirely) the need to centrally record changes in ownership each time originals change hands. | 02-04-2010 |
| 20100017620 | SOFTWARE SELF-CHECKING SYSTEMS AND METHODS - Software self-checking mechanisms are described for improving software tamper resistance and/or reliability. Redundant tests are performed to detect modifications to a program while it is running. Modifications are recorded or reported. Embodiments of the software self-checking mechanisms can be implemented such that they are relatively stealthy and robust, and so that it they are compatible with copy-specific static watermarking and other tamper-resistance techniques. | 01-21-2010 |
| 20090298480 | DATA COLLECTION AND TARGETED ADVERTISING SYSTEMS AND METHODS - Embodiments of a mobile device and server system are described. The mobile devices communicate with the server system and present targeted content, such as advertisements to the mobile device users. The content is targeted based on usage statistics stored on the server system which were previously collected from the mobile device. The server receives the usage statistics collected from the mobile device, makes inferences about preferences of users by tracking application and/or content usage behaviors of the users, generates recommendations for advertisements targeted toward the users of the mobile devices based on usage statistics; and transmits the recommendations to one or more of the mobile devices for presentation to the user(s). | 12-03-2009 |
| 20090037732 | TETHERED DEVICE SYSTEMS AND METHODS - Systems and methods are described for applying digital rights management techniques to tethered devices. In one embodiment, a host device is operable to translate a relatively sophisticated license into a simpler format for use on a relatively low-capability device. In another embodiment, a method of using extended SCSI commands to communicate over a USB connection is provided. | 02-05-2009 |
| 20090031431 | DYNAMIC MEDIA ZONES SYSTEMS AND METHODS - Systems and methods are described for applying digital rights management techniques to manage zones in electronic content. In one embodiment, zones are defined in a piece of electronic content, and a license is associated with the electronic content that indicates how the zones are to be accessed or otherwise used. A digital rights management engine governs access to or other use of the zoned content in accordance with the license. | 01-29-2009 |
| 20090031126 | Trust Management Systems and Methods - The present invention provides systems and methods for making efficient trust management decisions. A trust management engine is provided that processes requests for system resources, authorizations or certificates, and the identity of one or more root authorities that are ultimately responsible for granting or denying the requests. To determine whether a request should be granted, the trust management engine identifies a set principals from whom authorization may flow, and interprets each of the certificates as a function of the state of one or more of the principals. The processing logic iteratively evaluates the functions represented by the certificates, updates the states of the principals, and repeats this process until a reliable determination can be made as to whether the request should be granted or denied. The certificates may be evaluated until the state of the root authority indicates that the request should be granted, or until further evaluation of the certificates is ineffective in changing the state of the principals. | 01-29-2009 |
| 20090029718 | CONTENT PUBLISHING SYSTEMS AND METHODS - A system for publishing digital content is described which, in one embodiment, includes a beacon device associated with a first user configured to transmit identification information and information indicating its current position. A browsing device includes a display configured and adapted to display to a second user a representation of a local geographical area, and to selectively display to the second user content information associated with the first user, based at least in part on whether the location of the beacon device is within the local geographical area. | 01-29-2009 |
